AVX-512 can benefit the average Joe, it appears.
Sadly, Intel takes another loss here.
There is an issue, though: Intel disabled AVX-512 for its Core 12th, 13th, and 14th Generations of Core processors, leaving owners of these CPUs without them.
I'm surprised Intel would remove a feature that AMD provides in their desktop CPUs.
Hand written assembly is pretty common in video, no matter what they say. All modern video codecs have hand written assembly for all modern SIMD extensions, even on ARM. They didn't say anything about where these numbers come from. Likely compared against unoptimized C code. There will never be a case where having AVX-512 will give you that kind of speedup, because there will be fallbacks for more common extensions.
It's mostly because AVX-512 doesn't get used too well by compilers even today.
However, what makes this impressive for me is that it is x86 after all. ARM is way easier to write assembly for.
Hand written is impressive? I thought all code was hand written until AI
It's about code optimization and efficiency. Most assembly code these days just relies on compilers for optimization as hand optimizing is extremely time-consuming work.
To add to this, it's also very easy and very likely to write assembly that has zero speedup or even significant slowdown versus what the compiler will write.
It's handwritten assembly as opposed to bytecode generated by a compiler, from handwritten higher level language.
