News Intel Nukes Alder Lake's AVX-512 Support, Now Fuses It Off in Silicon

[Admin]

Intel is now disabling support for AVX-512 instructions in its Alder Lake processors by fusing it off inside the silicon.

Nukes is not a good term to use in the present situation.

poor choice of title words considering whats going on in the world today...

Intel's typical mentality at its finest.

intel: "The CPU canlt do it"

[MB maker makes it work via bios]

intel: ya nah fam we can't that. [physically prevents it from working]


Intel: you do it our way or gtfo.

 

[Kamen Rider Blade]

Intel should've done this from the very beginning.

AVX-512 is really a Enterprise specific Instruction Set.

Intel : we add AVX 512 support for RKL

Everyyone : it make RKL power hong, and run like inferno

Intel : we remove AVX 512 on ADL

Everyone : Intel Axes Alder Lake's AVX-512 Support, Now Fuses It Off in Silicon

Inte : what the F u guys even want

Now remove it from the Core Die design so you can reuse that transistor space for something else.

Wasting manufacturing space on AVX-512 on a consumer end design was fundamentally STUPID.

Now they waste space by "Fusing" it off?!?!?

Why even waste material putting it on the Die in the first place when you're going to fuse it off!

All those extra transistors, sitting there silently, doing nothing. Why even make them if you're not going to be able to use them.

To be fair they've done it for decades now for advanced instruction set extensions, starting with the FPU for 486SX. Those designs do not come cheap.

Though it must've been a first for something that was previously - and somewhat prominently - featured in their client-level processors.

Now it would be fun if AMD included a useful implementation of AVX-512 in their incoming Zen 4 consumer lineup.

Cheaper to mass produce one design instead of multiple.
Also dark silicon, it helps with absorbing and removing heat, larger surface = more heat spread.

Meh works for me!

Well they fused it off for performance issues. These chips no doubt get silly hot when encoding AVX-512 with a stock cooler. Consumers using this feature in error without know could end up with slowed clockspeed. Truth be told this is false advertising!

So you’re that delicate that you can’t hear the word nukes or read it? So ridiculous

NUKES NUKES NUKES

 

[NUKETHEWORLD]

I mean you have to disable the E-Cores to activate AVX-512

That alone should tell you why Intel doesn't like it, it's kinda wonky

 

[digitalgriffin]

Now if only NVIDIA would fuse off support for mining algs on LHR cards.

Yes yes I know compiled hash algs looks like regular compute algs. But they have repeatable and detectable patterns that can be picked up during the compile stage.

 

[Krakenthemall]

The real question is why Intel wants to absolutely get rid off avx 512 up to the point that mid life cpu cycle they decide to alter rest of cycle production which is inadvertently boost cpu resell pre-avx512 nuke.

As if we don't have enough to deal with price increase and would market play that led to morose pov, now we have big bang tech and feature inquisition and WE are supposed to say... "ok" ?

Really? The verb "nuke" was used in the Cold War in non-military applications. My friends and I would "nuke" our snacks in the microwave during the Reagan years when there were a lot more nuclear weapons in the world and Chernobyl was still burning. We "nuked" threats in AD&D with fireball or meteor shower. We'd "nuke someone's (butt)" in dodgeball. And we lived a few miles from major nuclear targets, like Strategic Air Command.

Is a somewhat increased risk of nuclear evaporation that novel and concerning?
