Nah the advantage seems to be long gone now. We are looking at 50% IPC indecrease
that means,
AVX512 will become AVX256
AVX256 will become SSE2
and SSE2 will turn into SSE64 whatever

It just works

Blasphemy! Nothing will change my mind about KFC being the best gaming CPU (I do like their nuggets, much better than McDonalds).

to someone not knowledgeable in this, if I have a 9700k, can I avoid having this mitigation enabled somehow? is my 9700k already using SGX ?

is this 50% supposed performance drop in all tasks? gaming? does it translate to 50% lower average fps or what?


on a sidenote I disabled meltdown and spectre mitigations with the inspectre app for the past year without any issues at all..

i wonder if the mitigation for this is why all our HPs are automatically BIOS updating this morning.

this is also why they should NOT have baked HP support assistant into the image.

gonna have to strip that out ASAP.

If something appears too good to be true, it probably is.

That thing is already the loudest pc in my house. If a fix cranks up the cpu usage that thing will go full turbo. Maybe I should just sell it.
I had the 7700HQ in a laptop and it was beast. But ran uber hot and each one of Dell's BIOS updates made it louder than the last. Eventually I sold it because the whine was wearing on me too much. Started hearing it in my dreams and that's when I decided it was enough. Haha.

My aunt's got a nice little HP 2400G machine with that support assist program on it. She refuses to let me remove it or to install a clean copy of LTSC so I wonder how it'll be affected by this mitigation.

Never much liked support assist myself but I see where it could be useful being automated and all.

Friday morning isn’t usually the best time for a slice of fried chicken, but it’s always the best time for several donuts. This was the problem at hand when KFC delivered 12 Chicken & Donuts sandwiches to In The Know’s New York office at 10:00 a.m.
tbh i googled the image w/o knowing the source.
