Question

A hatchery lab argues their office PCs “clock higher, so they must beat the graphics boards at fitting the grader.” What hardware comparison should the tester apply?

Accepted Answer

ML work is dominated by large parallel matrix math, so thousands of simpler GPU cores usually outperform a handful of high-clock CPU cores. — Fitting a grader is large parallel matrix math. Thousands of simpler GPU cores usually beat a handful of high-clock CPU cores. Clock speed is not the only hardware trait, and the two architectures are not identical for ML.

Answer

A higher CPU clock always beats a GPU for fitting, because raw clock speed is the only ML hardware trait.

Answer

CPU and GPU architectures are identical for ML, so the lab argument does not matter.

Answer

A request to size a GPU cluster as an ML platform engineer.
