someone spotted qualification CPU samples as having much lower clock speeds than the previous spotted engineering samples. this is concerning because, as the article points out, ES CPU are prototypes and usually have much lower speeds than the end product will while qualification CPU are made just before they go into production, so a much stronger indicator of what's actually coming. read the article to see the clock differences...

Intel's Arrow Lake chips may have lower clock speeds than previous CPUs — Core Ultra 9 QS achieves 5.7 GHz boost and 5.4 GHz across all P-cores
Arrow Lake QS sample reportedly improves boost clock speed by 100 MHz over the ES sample.
