In One Sentence

Future processor technology is moving beyond simply shrinking transistors toward a combination of advanced transistor architectures, backside power delivery, chiplets, 2.5D and 3D integration, high-bandwidth memory, specialized AI accelerators, heterogeneous computing and new computing paradigms designed to deliver more performance and intelligence with less energy and data movement.

Introduction: The Processor Is Entering a New Era

For decades, processor progress could be summarized relatively simply:

smaller transistors → more transistors → more performance.

That model is becoming increasingly difficult.

The industry is now approaching a point where performance improvements require innovation across the entire computing stack.

The future looks more like:

Better Transistors
       +
Better Power Delivery
       +
Better Architecture
       +
Chiplets
       +
3D Integration
       +
Faster Memory
       +
Specialized Accelerators
       +
Better Software
       ↓
Future Computing

The processor of the future may therefore look very different from today’s conventional CPU.


1. Full Definition: What Is Future Processor Technology?

Future processor technology refers to emerging semiconductor, architectural, packaging, memory, interconnect, acceleration and computing technologies intended to improve processor performance, energy efficiency, scalability, integration and workload specialization beyond conventional processor designs.

It includes both evolutionary technologies and fundamentally different computing approaches.


2. The Five Forces Driving Processor Evolution

Future processors are being shaped primarily by five pressures:

1. Performance

More computation is required.

2. Energy

Power budgets cannot increase indefinitely.

3. Memory

Processors increasingly need enormous data bandwidth.

4. Integration

More functions must fit into increasingly compact systems.

5. AI

AI workloads are changing the structure of computing itself.

These forces are interconnected.

3. Moore’s Law and the Changing Processor Industry

Moore’s Law describes the historical trend of increasing transistor counts on integrated circuits over time.

It was never simply a law stating that processors automatically become faster.

Historically, transistor scaling enabled:

  • more logic
  • larger caches
  • higher frequencies
  • greater integration
  • improved efficiency

But as transistor scaling becomes more difficult and expensive, processor innovation is increasingly coming from other areas.


4. Beyond Traditional Moore’s Law

The next phase is not necessarily:

“Moore’s Law ends.”

It is better understood as:

Performance scaling increasingly requires more than transistor scaling.

The industry is combining:

Transistor Scaling
+
Architectural Scaling
+
Packaging Scaling
+
Memory Scaling
+
Software Scaling

5. Gate-All-Around Transistors

One major transistor evolution is:

GAA : Gate-All-Around.

Unlike older planar transistor structures, GAA surrounds the channel more completely with the gate.

Conceptually:

Traditional
Gate
 ↓
Channel

GAA
Gate
 ↓↓↓
Channel
↑↑↑
Gate

The improved electrostatic control can help with continued transistor scaling.


6. Why GAA Matters

Better control of the transistor channel can potentially improve:

  • leakage characteristics
  • switching behavior
  • energy efficiency
  • performance
  • scaling capability

GAA is therefore an important transition in advanced semiconductor manufacturing.


7. Nanosheet Transistors

A common GAA implementation uses:

nanosheet transistors.

Instead of a single conventional channel geometry, multiple horizontal semiconductor sheets can form the transistor channel structure.

This allows manufacturers to continue scaling while maintaining strong gate control.


8. Forksheet and Future Transistor Structures

Beyond conventional nanosheet GAA, researchers and manufacturers are exploring further transistor structures such as:

  • forksheet
  • CFET
  • vertically integrated transistor architectures

These approaches aim to increase density and improve transistor scaling.


9. CFET

CFET = Complementary Field-Effect Transistor.

A CFET approach can vertically stack complementary transistor structures.

Conceptually:

n-type transistor
       ↑
p-type transistor

This could increase logic density by using the vertical dimension more aggressively.


10. Backside Power Delivery

Traditional chips generally route both:

  • power
  • signals

through the front side of the wafer.

Backside power delivery moves significant power-delivery infrastructure toward the opposite side.

Conceptually:

Front Side
────────────
Signal / Logic
────────────
Transistors
────────────
Back Side
Power Delivery

This can separate power and signal-routing requirements.


11. Why Backside Power Matters

Moving power delivery to the backside can potentially provide:

  • reduced power-routing congestion
  • improved signal routing
  • lower resistance
  • better power delivery
  • improved density

This is especially valuable as processors become increasingly complex.

12. The Frontside Bottleneck

As transistor density increases, the processor needs more connections.

The front side has to accommodate:

  • signal interconnects
  • power delivery
  • clocks
  • data movement

Separating power and signal paths can relieve some of this congestion.


13. Advanced Interconnect

Future processors will require increasingly sophisticated on-chip and package-level interconnects.

Important technologies include:

  • high-density electrical interconnect
  • silicon interposers
  • advanced substrates
  • optical interconnect
  • die-to-die interfaces

The processor is becoming a communication system as much as a computation system.


14. Chiplets

One of the most important architectural trends is:

chiplet-based design.

Instead of creating one enormous die:

One Huge Die

manufacturers can combine smaller dies:

CPU Chiplet
     +
GPU Chiplet
     +
I/O Chiplet
     +
Cache Chiplet
     +
Accelerator

15. Why Chiplets Are Important

Chiplets can provide:

  • modular design
  • manufacturing flexibility
  • scalability
  • process-node mixing
  • potentially improved yield
  • product reuse

A company can use different process technologies for different functions.


16. Heterogeneous Chiplets

Future processors may contain chiplets optimized for different purposes.

For example:

Advanced CPU Chiplet
        +
GPU Chiplet
        +
AI Chiplet
        +
I/O Chiplet
        +
Cache Chiplet
        +
Memory Interface

This is heterogeneous computing at the package level.


17. 2.5D Integration

2.5D packaging places multiple dies beside each other with very high-density connections.

It is especially useful for:

  • AI accelerators
  • GPUs
  • high-performance computing

The package becomes an extension of the processor architecture.


18. 3D Integration

3D integration stacks semiconductor dies vertically.

Layer 4
────────
Layer 3
────────
Layer 2
────────
Layer 1

This increases density without requiring everything to occupy additional horizontal silicon area.


19. Why 3D Matters

3D integration can potentially provide:

  • greater density
  • shorter communication distances
  • higher bandwidth
  • larger effective cache
  • closer compute-memory integration

But it creates significant thermal challenges.


20. 3D Cache

Stacked cache is already an important direction in processor design.

Instead of placing all cache beside CPU cores:

CPU + Cache

additional cache can be stacked vertically:

Cache
──────
CPU

This can dramatically increase cache capacity.


21. Memory Is Becoming the Bottleneck

Modern processors can execute enormous numbers of operations.

But computation is useful only if data arrives quickly enough.

This creates:

the memory wall.

Conceptually:

More Compute
     ↓
More Data Required
     ↓
Memory Bottleneck
     ↓
Idle Compute

Future processors therefore need better memory systems.


22. High-Bandwidth Memory

HBM = High Bandwidth Memory.

HBM provides extremely high memory bandwidth through wide interfaces and stacked memory structures.

It is particularly important for:

  • AI accelerators
  • GPUs
  • HPC
  • data centers

23. Compute + HBM

A future AI processor can be viewed as:

        Compute
     ┌───────────┐
     │ GPU / AI  │
     └───────────┘
          ↕
      High-Speed
      Interconnect
          ↕
     ┌───────────┐
     │    HBM    │
     └───────────┘

The memory system becomes a core part of accelerator design.


24. Memory-Centric Computing

Traditional computing emphasizes:

compute → memory

Future architectures increasingly optimize:

compute + memory + data movement together.

This can involve:

  • larger caches
  • stacked memory
  • near-memory computing
  • processing-in-memory concepts
  • high-bandwidth interconnects

25. Near-Memory Computing

Near-memory computing places processing capability physically closer to memory.

The goal is to reduce:

  • data-transfer distance
  • latency
  • energy consumed moving data

Conceptually:

Compute
 ↕
Very Close Memory

26. Processing-in-Memory

PIM = Processing-in-Memory.

PIM attempts to perform certain computations within or extremely close to memory structures.

The motivation is simple:

Moving data can consume significant energy.

Reducing data movement can therefore improve efficiency for appropriate workloads.


27. AI Is Changing Processor Architecture

AI workloads have fundamentally different characteristics from many traditional CPU workloads.

They involve:

  • massive matrix operations
  • parallel computation
  • large models
  • high memory bandwidth
  • repeated tensor operations

This is driving specialized AI architectures.


28. AI Accelerators

Future processors will increasingly contain specialized AI engines.

CPU
GPU
NPU
Tensor Engine
AI Accelerator

The distinction between traditional processor categories may increasingly blur.


29. CPU + GPU + NPU Convergence

A future SoC could look like:

             SoC
              │
    ┌─────────┼─────────┐
    ↓         ↓         ↓
   CPU       GPU       NPU
    │         │         │
    └─────────┼─────────┘
              ↓
        Shared Memory
              ↓
        AI / Applications

The workload is distributed according to efficiency and capability.


30. On-Device AI

AI processing is increasingly moving from remote servers toward local devices.

Advantages can include:

  • lower latency
  • improved privacy
  • reduced network dependence
  • offline functionality
  • potentially lower cloud cost

This increases demand for efficient local AI accelerators.


31. Edge AI

Edge AI places AI processing near where data is generated.

Examples include:

  • smartphones
  • cameras
  • vehicles
  • industrial systems
  • IoT devices

The processor must therefore optimize:

AI performance per watt.


32. AI Efficiency Becomes More Important

Future AI processors will increasingly be evaluated using:

  • performance per watt
  • energy per inference
  • memory bandwidth
  • latency
  • sustained throughput

Raw TOPS alone will become an increasingly incomplete measure.


33. Quantization

AI models can often use lower numerical precision.

Examples include:

  • FP16
  • BF16
  • INT8
  • INT4

Lower precision can reduce:

  • memory usage
  • bandwidth requirements
  • computational cost

when supported appropriately by the model and hardware.


34. Sparse Computing

Some AI models contain computation that can be skipped.

Hardware can potentially exploit:

sparsity

to reduce unnecessary operations.

This can improve efficiency for workloads that expose useful sparsity patterns.


35. Transformer-Oriented Hardware

Modern generative AI relies heavily on transformer architectures.

Future AI accelerators are increasingly optimized for operations such as:

  • matrix multiplication
  • attention
  • tensor operations
  • memory movement

This is changing accelerator architecture.


36. Specialized AI Silicon

Future processors may increasingly contain workload-specific acceleration.

For example:

General CPU
     +
Graphics GPU
     +
AI Accelerator
     +
Video Engine
     +
Image Processor
     +
Security Engine

The processor becomes an ecosystem of specialized engines.


37. Neuromorphic Computing

Neuromorphic computing attempts to model certain principles of biological neural systems in hardware.

Instead of conventional processor architectures, neuromorphic systems may emphasize:

  • event-driven computation
  • spiking neural networks
  • distributed processing
  • low-power operation

38. Why Neuromorphic Computing Matters

Traditional processors continuously manipulate digital data.

Neuromorphic systems can instead operate around discrete events.

For suitable workloads, this could potentially reduce unnecessary computation.

Potential applications include:

  • robotics
  • sensors
  • edge AI
  • autonomous systems

39. Photonic Computing

Photonic computing uses light or optical techniques to perform or transport certain computational operations.

Potential advantages include:

  • high bandwidth
  • parallel optical data movement
  • potentially lower communication energy for specific applications

It is particularly interesting for AI and data-center interconnects.


40. Optical Interconnect

Even if optical computing does not replace conventional electronic processors, optical communication could become increasingly important.

Conceptually:

Compute
 ↓
Electrical → Optical
 ↓
High-Bandwidth Link
 ↓
Optical → Electrical
 ↓
Compute

This can address communication bottlenecks in large systems.


41. Quantum Computing

Quantum computing uses quantum-mechanical phenomena to process information in fundamentally different ways.

It is not a direct replacement for CPUs.

Instead, quantum computers are intended for particular classes of problems where quantum algorithms may provide advantages.

Potential areas include:

  • cryptography
  • chemistry
  • materials science
  • optimization
  • simulation

42. Quantum Processor vs CPU

TechnologyPrimary Computing Model
CPUGeneral-purpose classical computing
GPUMassively parallel classical computing
NPUNeural-network acceleration
NeuromorphicEvent-driven / brain-inspired computing
PhotonicOptical computation or communication
QuantumQuantum information processing

These technologies are likely to coexist rather than one completely replacing the others.


43. Domain-Specific Accelerators

The future may include increasingly specialized processors.

Instead of:

one processor does everything

the architecture becomes:

CPU
├── AI Accelerator
├── Video Accelerator
├── Security Accelerator
├── Networking Accelerator
├── Cryptography Accelerator
└── Signal Processor

Each engine handles the workload for which it is most efficient.


44. Reconfigurable Computing

Some future processors may use hardware that can be configured for different workloads.

Examples include:

  • FPGAs
  • reconfigurable accelerators
  • adaptive compute architectures

This provides a balance between fixed-function hardware and general-purpose processors.


45. Processor–Memory Co-Design

Future processors will increasingly be designed together with their memory systems.

Instead of:

Processor
+
Memory

the architecture becomes:

Compute
+
Cache
+
HBM
+
Interconnect
+
Memory Controller

as one coordinated system.


46. Data Movement as a First-Class Problem

In future computing, the question will increasingly be:

How much energy does it take to move the data?

rather than only:

How many operations can the processor execute?

This is particularly important for AI.


47. 3D Memory and Compute

Future packages may increasingly integrate:

Compute Die
     ↓
Cache
     ↓
Memory

or combinations of:

CPU
GPU
NPU
Cache
HBM

within a single package.

This could dramatically change system architecture.


48. Thermal Management Becomes Harder

More integration means more heat in smaller spaces.

The challenge becomes:

More Compute
 ↓
More Power
 ↓
More Heat
 ↓
Harder Cooling

Advanced packaging therefore has to evolve alongside advanced processors.


49. Thermal-Aware Architecture

Future processors may increasingly optimize computation based on temperature.

For example:

Workload
 ↓
Thermal State
 ↓
Engine Selection
 ↓
Frequency / Voltage
 ↓
Power Allocation

The processor can choose the most efficient execution strategy dynamically.


50. Energy-Proportional Computing

Future systems will aim to minimize wasted energy when workload demand is low.

The ideal concept is:

Low Workload
→ Low Power

High Workload
→ High Power

with minimal energy consumed outside active computation.


51. AI-Assisted Processor Management

AI itself may help manage processors.

Potential applications include:

  • workload prediction
  • power optimization
  • thermal management
  • task scheduling
  • resource allocation

This creates an interesting feedback loop:

AI
 ↓
Manages Hardware
 ↓
Hardware Runs AI

52. Hardware–Software Co-Design

Future processor development will increasingly involve simultaneous optimization of:

Architecture
      ↕
Compiler
      ↕
Runtime
      ↕
Operating System
      ↕
AI Framework
      ↕
Application

The distinction between hardware design and software optimization will continue to blur.


53. Compiler-Driven Hardware

Future processors may be designed with specific compiler strategies in mind.

The compiler can determine:

  • instruction selection
  • workload distribution
  • accelerator usage
  • memory placement
  • vectorization
  • optimization

This makes the compiler part of the processor’s performance architecture.


54. Domain-Specific Software Stacks

AI, graphics and scientific computing increasingly require specialized software stacks.

For example:

AI Application
 ↓
Framework
 ↓
Compiler
 ↓
Runtime
 ↓
NPU

The quality of this stack can determine how much of the hardware’s theoretical capability becomes usable.


55. Universal vs Specialized Processors

The future is unlikely to be purely:

general-purpose

or purely:

specialized.

Instead:

General Purpose
       +
Specialized Accelerators
       +
Adaptive Software
       ↓
Heterogeneous Computing

This is likely to become the dominant model.


56. Processor Architecture by 2030s

A future high-end computing platform could conceptually resemble:

                 SYSTEM
                    │
     ┌──────────────┼──────────────┐
     ↓              ↓              ↓
   CPU            GPU            AI/NPU
     │              │              │
     └──────────────┼──────────────┘
                    ↓
             Shared / Unified
               Memory Fabric
                    ↓
        ┌───────────┼───────────┐
        ↓           ↓           ↓
       HBM       3D Cache    Storage
                    │
             High-Speed I/O

The exact architecture will vary by device class.


57. Future Smartphone Processor

A future smartphone SoC could integrate:

  • advanced CPU cores
  • powerful GPU
  • AI accelerator
  • image processor
  • video engine
  • modem
  • security processor
  • display engine
  • advanced memory controller

The major challenge will be:

performance within a tiny thermal envelope.


58. Future Laptop Processor

Future laptop processors will likely emphasize:

  • CPU efficiency
  • integrated graphics
  • NPU performance
  • media acceleration
  • memory efficiency
  • battery life
  • AI workloads

The NPU will increasingly become a standard component rather than an unusual feature.


59. Future Data-Center Processor

Data-center processors will increasingly prioritize:

  • performance per watt
  • AI acceleration
  • memory bandwidth
  • chiplet scalability
  • HBM
  • high-speed networking
  • advanced cooling

The package may become almost as important as the compute die.


60. Future AI Accelerator

A high-end AI accelerator may combine:

Compute Dies
+
HBM
+
High-Speed Interconnect
+
Advanced Packaging
+
Dedicated AI Software Stack

This is fundamentally different from the traditional CPU model.


61. Processor Performance Will Become More Systemic

Future performance comparisons will increasingly need to measure:

  • compute throughput
  • memory bandwidth
  • latency
  • power
  • thermal behavior
  • software optimization
  • interconnect efficiency

A single benchmark number will become increasingly inadequate.


62. New Processor Metrics

Future processor evaluation may increasingly emphasize:

Performance per watt

How much work is achieved for each watt.

Energy per inference

Important for AI.

Memory bandwidth per compute unit

How effectively compute resources are fed.

Data movement energy

Energy required to move data.

Sustained throughput

Long-duration performance.

Latency

Time required to complete an operation.


63. The End of the “GHz Race”

Processor development has already moved beyond simply increasing clock frequency.

The future emphasis is increasingly:

IPC
+
Parallelism
+
Specialization
+
Memory
+
Packaging
+
Efficiency
+
Software

Clock speed will remain relevant, but it will no longer define processor progress by itself.


64. The End of the “Core Count Race”

More cores can increase performance for parallel workloads.

But adding cores also creates:

  • memory demands
  • power demands
  • scheduling complexity
  • interconnect requirements

The future is therefore not simply:

more cores.

It is:

more useful computation per unit of energy and silicon.


65. The New Processor Equation

A useful conceptual model for future processor design is:

Performance
=
Compute
×
Memory
×
Interconnect
×
Software
×
Thermal Capacity

If any major component becomes a bottleneck, the overall system can be constrained.


66. Processor Technology Convergence

Several previously separate technologies are converging:

CPU
GPU
NPU
DSP
ISP
Memory
Networking
Security
      ↓
Integrated Computing Platform

This is especially visible in SoCs and AI systems.


67. The Package Becomes the System

Historically:

chip = processor

Increasingly:

package = computing platform

A package may contain:

  • multiple compute dies
  • cache
  • HBM
  • I/O dies
  • accelerators

This is a major architectural transition.


68. The System Becomes the Processor

At the highest level:

Transistor
 ↓
Core
 ↓
Processor
 ↓
SoC
 ↓
Package
 ↓
System
 ↓
Software Ecosystem

The boundaries between processor, memory and platform are becoming less distinct.


69. What Will Replace the CPU?

The most likely answer is:

nothing singular.

The CPU will remain important.

Instead, it will increasingly work alongside:

  • GPUs
  • NPUs
  • AI accelerators
  • DSPs
  • domain-specific engines
  • memory accelerators

The future is heterogeneous rather than CPU-less.


70. What Will Replace Traditional Scaling?

Not one technology.

The industry is likely to combine:

GAA
+
Backside Power
+
Chiplets
+
2.5D
+
3D
+
HBM
+
Specialized Accelerators
+
Software Optimization

This is the emerging post-traditional scaling model.


71. Future Processor Technology Matrix

TechnologyPrimary Problem It Addresses
GAAContinued transistor scaling
NanosheetsAdvanced transistor density/control
Backside PowerPower-delivery and routing congestion
ChipletsScaling, yield and modularity

PIMData-movement cost
AI AcceleratorsAI efficiency
Neuromorphic ComputingUltra-efficient event-driven processing
Photonic ComputingHigh-bandwidth computation/interconnect
Quantum ComputingSpecialized quantum algorithms
Hardware–Software Co-DesignBetter real-world utilization

72. What Is Likely vs Experimental?

Not every future technology is equally mature.

More immediate

  • GAA
  • backside power delivery
  • chiplets
  • advanced packaging
  • 3D cache
  • HBM
  • specialized AI accelerators

Developing

  • 3D logic integration
  • hybrid bonding
  • processing-in-memory
  • optical interconnect
  • advanced heterogeneous computing

Longer-term / specialized

  • neuromorphic computing
  • photonic computing
  • quantum computing

This distinction is important when discussing future technology.


73. Future Does Not Mean Replacement

A common mistake in technology reporting is:

“Technology X will replace technology Y.”

The real future is more likely to be heterogeneous.

For example:

CPU
+
GPU
+
NPU
+
HBM
+
Chiplets
+
Optical Interconnect

Different technologies can coexist.


74. The Future Processor Is a Distributed Computing System

Instead of one monolithic computational engine:

One Processor

the future may resemble:

CPU ── GPU ── NPU
 │      │      │
 └── Memory Fabric ── HBM
          │
      Chiplets
          │
     3D Package

Computation becomes distributed across specialized resources.


75. The Biggest Future Bottleneck

The most important bottleneck may not be transistor density.

It may increasingly be:

data movement.

Moving data between:

  • CPU
  • GPU
  • NPU
  • memory
  • storage

requires time and energy.

Future architectures will increasingly minimize this movement.


76. The Future of Processor Efficiency

The next generation of efficiency will come from multiple levels:

Transistor Efficiency
       ↓
Architecture Efficiency
       ↓
Memory Efficiency
       ↓
Interconnect Efficiency
       ↓
Packaging Efficiency
       ↓
Software Efficiency
       ↓
System Efficiency

Efficiency is becoming a system-level property.


77. Future Processor Development Philosophy

The traditional question was:

How do we make the transistor smaller?

The emerging question is:

How do we move information, compute it and store it with the least possible energy?

That change in thinking is one of the most important developments in processor technology.

  1. What changed in the transistor?
  2. What changed in the architecture?
  3. What changed in memory?
  4. What changed in packaging?
  5. What changed in power efficiency?
  6. What changed in software?
  7. What workloads actually benefit?
  8. Is the improvement peak or sustained?
  9. Is the technology commercially available?
  10. What is still experimental?

These questions separate technology analysis from marketing.


80. Common Future Processor Misconceptions

 

Myth 1: Moore’s Law ending means processor innovation ends.

False.

Innovation is increasingly shifting toward architecture, packaging, memory and specialization.

Myth 2: Chiplets will replace all monolithic processors.

Unlikely.

Both approaches have advantages.

Myth 3: 3D stacking automatically makes processors faster.

False.

Thermal and interconnect challenges remain.

Myth 4: HBM replaces conventional system memory.

Not universally.

It is optimized for specific high-bandwidth applications.

Myth 5: AI accelerators will replace CPUs.

Unlikely.

Different workloads require different processing architectures.

Myth 6: Quantum computing will replace PCs.

Highly unlikely.

Quantum computing targets specialized workloads.

Myth 7: Smaller process nodes automatically mean better processors.

False.

Architecture, packaging, memory, software and power all matter.


81. The Future Processor Stack

The complete future architecture can be visualized as:

This is particularly evident in modern SoCs and AI systems.


83. What the Next Decade Could Bring

The next generation of processors is likely to combine:

  • GAA transistor technologies
  • advanced process nodes
  • backside power
  • chiplets
  • advanced substrates
  • 2.5D integration
  • 3D stacking
  • stacked cache
  • HBM
  • AI accelerators
  • heterogeneous computing
  • hardware–software co-design

More experimental technologies may gradually enter selected markets.


84. The Long-Term Direction

The overall trajectory can be summarized:

Smaller Transistors
       ↓
More Transistors
       ↓
More Specialized Engines
       ↓
Chiplets
       ↓
3D Integration
       ↓

       ↓
Heterogeneous Intelligence

The processor is becoming increasingly specialized, integrated and software-aware.


85. Final Takeaway

The future of processors is not one breakthrough.

It is a convergence of technologies.

GAA continues transistor scaling.

Backside power delivery improves power distribution.

Chiplets provide modular scalability.

2.5D and 3D packaging increase integration density.

3D cache and HBM attack memory bottlenecks.

AI accelerators provide efficient specialized computation.

Neuromorphic and photonic technologies explore fundamentally different approaches.

Quantum computing targets specialized problems beyond classical processor architectures.

And hardware–software co-design connects all of these technologies to usable applications.

The most important shift is this:

The future processor will not be defined by the CPU alone. It will be defined by how efficiently computation, memory, interconnect, packaging, specialized accelerators and software work together.

The industry is therefore moving from:

“More transistors.”

toward:

“More useful computation per unit of energy, silicon, bandwidth and time.”

That is the foundation of the next generation of computing.
