Isn’t the issue with AVX-512 is that different CPUs support different instructions? https://en.m.wikipedia.org/wiki/AVX-512 It might eventually get normalized but atm it’s a bit of a mess.

It's a bit less messy if you ignore the GPU-like Xeon Phi ( Knights Landing and Knights Mill ) and the failed Cannonlake that Intel definitely would prefer everyone pretend never happened. But that still leaves you with a progression of four levels of expanding support, and the Cooper Lake mess of having BFLOAT16 but not the stuff added in Ice Lake and Tiger Lake . If you don't cut down the support table to eliminate…

I think Icelake and Tiger lake not having BF16 is going to be a big issue especially for machine learning applications, I can’t find what Rocket Lake supports yet but I’m guessing it’s going to be similar to Tiger Lake.

There is also the big unknown of what kind of support AMD will bring to the table.

I think Intel is banking on people using OneAPI more than writing AVX-512 code using intrinsics or compiler magic.

At that point compatibility might be not as much of an issue if you ignore potentially drastic differences in performance.

> The improvements Intel has made to its processor seem to do very little in our gaming tests, and in a lot of cases, we see performance regressions rather than improvements.

> The answer from our side of the fence is that Rocket Lake has some regressions in core-to-core performance and its memory latency profile.

Anyone have any idea when intel's 10nm will hit desktop? Are they making any progress at all? Are they just planning on skipping straight to 7 at this point?

This is half- to full- snark: When they outsource to TSMC.

At some point Intel will get their act together and only be one step behind rather than... christ, are they three steps behind? They just have way too much money.

But it does look like with the management purges, re-hires of old guard, and other changes it'll be a while before they right ship.

There's probably pride to overcome, since a lot of process choices probably are "stake my career" things and now those careers may be coming to an end.

The interesting thing may be that Intel now not only must close a gap in process technology, they may also need to change instruction set and make an ARM offering.

I think at this point we're just waiting for Windows and Linux to be fully supported on the M1 or for ARM to come out with a system on a chip that's documented enough for Windows and Linux to make a port.

There already are other SoCs for ARM based PCs. Qualcomm has the 8cx "Gen 2" chip, but it performs really badly compared to M1 (https://www.cpu-monkey.com/en/compare_cpu-qualcomm_snapdrago...).

Considering how little fab capacity there is for new designs right now (and Apple has probably booked it all out for months/years to come), I can't see this situation changing much. AMD is the closest but they also have insane supply shortages right now.

This is pathetic. At this point Intel should open up x86 and become like ARM as this is proven to work now. I wonder how badly Intel's mishap set humanity back by releasing essentially the same processors each year...

We're simply fortunate this monopoly was more easily cracked that ones like Microsoft.

I'm just flabbergasted that Intel has Thunderbolt support integrated into it's mobile chips, but on desktop it's business as usual, left to motherboard vendors to implement Thunderbolt themselves with the normal slew of add-on chips. Super frustrating that desktop users can't expect modern connectivity. It should be on the chip, like mobile. Notably, one can take any old TB4 cable, connect two modern Intel laptops, a…

Well USB-C/Thunderbolt rollout and HDMI 2 to laptops has been as glacial as ever.

How is it that mobile phones get technology support two years before laptops and desktops?

Why would you wait for that when you can have a faster CPU in the form of the 5800X today? The M1 is a phenomenal laptop CPU, but it's still not faster than AMD's desktop offerings, either. At least not according to the specint results in the article.

Good thing nobody actually uses AVX512

Interestingly enough, the AVX512 test was the easy win for Intel. Nobody uses it because it wasn't available and, when available, wasn't much faster overall. Now it is.

Is it though? The vast majority of PCs even on the enthusiast level aren't going to have coolers that can handle 300w for any sustained period.
