from your all around deep knowledge what do you think is the realistic advantage of AVX512 over AVX2?Latest builds of X264 have some preliminary support in them.
5-10% performance improvement over AVX2, depending on the used preset currently (according to the devs).
thanks - what software?
will I see this on KLITE?
thanks
Is AMD allowed to use these commands ( 512 ) ?
Or do they have similar / another name?
I did not understand what " resource "increasing the resources in the core.
You have to have dedicated pipelines for processing this kind of work and basically an answer sheet.I did not understand what " resource "
in theory AVX-512 should bring 100% over AVX2 ?
There is supposed to be no difference in theory and practice, but in practice there is. 100% more performance over AVX2 would only happen ideally in something like LINPACK.I did not understand what " resource "

What's point of AVX2/AVX512 when We do have GPU workloads? Isn't GPU rival to AVX?
AVX512 advantages over AVX2 in practically useful work is extremely limited in both applicability and performance.
AVX512 Integer performance is still only 20 (or 40, can't remember) percent over AVX2, according to Sandra. As for FP, it's still limited to array or matrix operations as long as they don't run into memory bottlenecks, and in isolation. Fawning over big performance deltas in MKL FFT/LINPACK isn't really what you'd call an example of overall usefulness. When software is written with varying degrees of competence when it comes to exposing vectorizable paths, performance is going to be all over the place. And I'm not even talking about the physical restrictions of die area, clock speeds and power consumption.AVX512VL should allow AVX512 to be much more practical and useful in general computing.
Of course this will take years to manifest unfortunately.

If I may ask you. How much more power does it needs?
Why is 264 still being developed? 265 is superior in every way last time I checked.
There are many devices that cannot do full HEVC/h.265 hardware decoding, be it CPUs, GPUs, mobile phones, set-top boxes, etc. Companies cannot abandon h.264 just yet, until the large majority of people's devices support h.265.
P.S. This is off-topic though.
