Intel'овские процессоры
Я тут почитал вот это:
https://en.wikipedia.org/wiki/Alder_Lake
>The P and E cores of early versions of Alder Lake CPUs reported different CPUID models. This has caused issues with digital rights management systems that perceive the P and E cores as being separate computers, and falsely enforce license restrictions preventing a particular piece of software from being executed on more than one device at a time.
>This problem has been fixed in a microcode update. The P and E cores now return the same CPUID when both are enabled. A different CPUID is reported when E cores are disabled and only P cores are enabled. The AVX-512 instruction set extension is implemented in the P cores but disabled due to incompatibility with the E cores.[32] Hackers have shown that it is possible to enable the AVX-512 instructions on the P cores when the E cores are disabled and an old microcode version is used.
Это какая-то жесть. Овернжиниринг высшей степени.
Re:Intel'овские процессоры
для ширнармасс выбор алдэерлэйков: N95-N97-N100 и какой-нибудь i3 в той же ценовой. главное - прикрутили аппаратное декодирование av1, а не вот это всё..
кроме того, avx-512 ни в приложениях, ни в железе так широко применяться не будет, как avx2. оч специфичная штука с нюансами в компиляторах (шланг/гэцэцэ).
Linus Torvalds: "I hope AVX-512 dies a painful death, and that Intel starts fixing real problems instead of trying to create magic instructions to then create benchmarks that they can look good on" https://www.zdnet.com/article/linus-torvalds-i-hope-intels-avx-512-dies-a-painful-death/
