Intel Black Hat Policies

Filed under: Uncategorized — ioconnor @ 2:24 pm

even benchmarking programs are affected by this, up to a point where benchmark results can differ greatly depending on how a processor identifies itself. Ars found out that by changing the CPUID of a VIA Nano processor to AuthenticAMD you could increase performance in PCMark 2005’s memory subsystem test by 10% – changing it to GenuineIntel yields a 47.4% performance improvement! There’s more on that here [print version – the regular one won’t load for me].

This is from “Intel Forced to Remove “Cripple AMD” Function from Compiler?

Wouldn’t it be great if Intel were forced to pay these companies back?
