It's not just about clock speed. CPI has been steadily improving across processor generations, even when the clock speed doesn't meaningfully change.

- atty 4y agoSorry do you mean IPC (instructions per clock) or is there another term that I’m not aware of?
- vlovich123 4y agoCycles per instruction.
- wtallis 4y ago"Cycles per instruction" sounds more like a measurement of instruction latency rather than instruction throughput, and I don't think instruction latency has improved as much in the past decade as instruction throughput: the most significant microarchitecture trend has been toward wider CPUs with more execution ports, wider instruction decoders, and larger reorder buffers.
