Architecture over time

CPU Technology Timeline

The corpus spans 1964-2026. The technology changes as processors move from board-level control and narrow datapaths to pipelines, caches, speculation, multicore fabrics, SoCs, and package-scale integration.

1970s

Integrated Microprocessor

CPU function moves from boards and chip sets into single-chip control objects.

1980s

Caches And Pipelines

On-chip locality and overlapping stages make the CPU a timing machine rather than only an instruction interpreter.

1990s

RISC, Superscalar, And Out-of-Order

The processor learns to discover and exploit parallelism inside ordinary instruction streams.

2000s

Frequency Wall

Power and misprediction penalties reveal that higher clocks alone cannot define CPU progress.

2010s

Multicore And Uncore

Cores, caches, memory controllers, and fabric become one processor object.

2020s

SoC And Chiplet CPUs

The CPU is increasingly a cluster inside a package or SoC shared with memory, GPUs, NPUs, and IO.
