AMD is the only x86 CPU vendor I will remotely bother with at this point, but folks shouldn't use x86 anyway if they can avoid it: https://www.theverge.com/2024/6/14/24178751/intel-raptor-lake-crash-fix-etvb-not-yet
Intel says it still doesn’t have the true fix for its crashing i9 desktop chips

Despite what you might have seen earlier today, Intel says it doesn’t have a final fix for its 13th and 14th Gen Intel Core i9 “Raptor Lake” and “Raptor Lake S” chips just yet.

and for the love of all things, apply CPU microcode updates on your machines, *especially* with x86, where basically *zero* x86 cores have been taped out in the past 20 years that did not immediately need bugfixing in microcode

@ariadne and then you have the gnu libre people who remove any microcode blobs, even though there is one running on there cpu anyway... might as well update it to get security fixes

@kate those folks literally believe that you can make a microcoded CPU run an entirely different ISA just by changing the microcode

@ariadne yk cpu is just fpga+microcode, right??

@kate if that were actually true, wouldn't the microcode be, oh, i don't know, much much larger in size?

@ariadne @kate Intel had to do some code golfing because they ran out of patch slots for uCode updates on some generations after the Spectre/Meltdown times

@kate @ariadne idk if you're joking but that just ain't true, real FPGAs cannot come close to ASICs in terms of raw perf, we're talking 40 series size cards hitting a few hundred Hz max
