That´s a bit wierdi. On your AMD processor, my version produces the same results as in Intel. But, on mine processor, it seems to happens the opposite. I´m wonderin what is happenning for such different results.

I guess it's due to optimization of the Ryzen Arch with each generation.
Would be interesting to see how Ryzen 5000 and 7000 performs.

No, I never tested it. The documentation is lousy

Hi JJ

I´ll try to find some more info to see if it can be implemented on x86. I found some few information (in fasm as well), that maybe could give a idea where to start later

https://board.flatassembler.net/topic.php?t=22502
https://www.felixcloutier.com/x86/vgatherdps:vgatherqps
https://stackoverflow.com/questions/21774454/how-are-the-gather-instructions-in-avx2-implemented

At least, now I got the syntax right. This assembles with UAsm64:

One more, please...

There is one Avx2 algo. If you run it on an older cpu, it will simply output "No Avx2" (I hope that works...)

Ok, there was a little glitch. Corrected version attached, it even builds without MasmBasic.

As you can see, the Avx2 version is not particularly fast. However, it was fun to code it, and I almost understood one of the exotic gather instructions ;-)

18324  cycles for 100 * Bin2Hex Avx2

Maybe AVX2 module power up on demand.

Wow, this is weird - and it's not an old CPU

I'm wondering how is the program calculating cycles on my machine, I have no AVX2 apparently. But looking at the cycle count results, my computer is doing something to get those results... or is that from just running the 'overhead' code? guga? jj2007?
