The Clock Myth
Frequency (Hz) is no longer the sole measure of computer performance. Modern CPUs use deep pipelines and multi-core architectures to achieve more work at lower clock speeds.
- CPI: Cycles Per Instruction (lower is better)
- IPC: Instructions Per Clock (higher is better)
- TDP: High frequency requires exponential voltage/heat.

Frequently Asked Questions
Why did clock speeds stop increasing around 5-6 GHz?
Hitting the "Power Wall." Increasing frequency requires more power, which creates heat that silicon cannot dissipate quickly enough without melting.
Is a 4GHz i3 faster than a 3GHz i7?
Not necessarily. The i7 might have higher IPC, more cores, and larger cache, allowing it to complete more total instructions per second despite the lower clock.
