So,what`s difference between 512 and normally?

So,waht`s the difference between the AVX construction we met on our customers Core series processor and AVX-512 ON Xeon?

I am not understand the explain on weki.....

Basically it lets the processor work on 512 bits worth of data per clock cycle. Not relevant to most workloads, but it's incredible for massive data processing work.

AVX 512 and GPUs address similar problems in different ways. AVX 512 does more data computation with the same number of cores, GPUs just shove in a huge amount more cores. For gaming you don't need the ability to access hundreds of GB worth of RAM, so a GPU is much more useful there, whereas in something like a financial simulation you might need that much memory, which is where AVX 512 comes in since CPUs do have the ability to have that much RAM. Nvidia's NVLink is something trying to address the problem of limited memory amount on GPUs by making super high speed links so they can share RAM.

 

TL;DR:

AVX 512 no make game fast.

Some people seem to think that the purpose of SSE/2 and AVX/2/E is solely to allow operations on longer integers. That is actually the least of it's purposes, and is only a by product of their implementations.

These instruction set extensions provide SIMD, or Single Instruction Multiple Data, models to programmers. They are meant to process the same operation on more than one unit of data at once.

For example, each 256 bit register can be treated as 8 32 bit integers, an operation of the form C = A + B can then perform 8 separate additions of 8 pairs of 32 bit integers in one instruction.

 

One should also be aware that it is not true SIMD in the sense that all of the additions (in this example) are physically being carried out at once: Rather, like all of Intels instructions, it is a highly optimized microprogram that is able to leverage parts of the processor not accessible to normal developers to improve the performance of "common" operations.

Hold on,bro,you guy`s portrait is pretty insane
