The part of a computer that actually thinks, while everything else just carries messages.
means The hardware component — like a CPU or GPU — that executes instructions and performs the actual calculations inside a computing device.
from A straightforward 20th-century technical compound: 'process,' from Latin processus (a going forward, a course), fused with 'unit,' from Latin unus (one) via its sense of 'a single standardized component.' The phrase rose with early computer engineering, when machines were literally built from discrete labeled 'units' — arithmetic units, control units, memory units — wired together into a working whole. 'Processing unit' simply named the one that did the processing, and it stuck through generations of hardware, from room-sized mainframes down to the sliver of silicon in your pocket.
- origin term
- Coined for mainframes before chips existed
- cpu vs gpu
- One does tasks, one does crowds
- speed myth
- Clock speed alone no longer predicts performance
- heat problem
- Most design limits are thermal, not logical
