Hello you fine Internet folks,

Today's article is a rebuttal to the article "Why x86 Needs To Die" as well as standing as a rebuttal to the wider argument of "RISC vs CISC" and why in today's age it is a very dead argument.

Hope y'all enjoy!

https://chipsandcheese.com/2024/03/27/why-x86-doesnt-need-to-die/

P.S. Please do not harass the author of that Hackaday article, this article was written out of a frustration that the RISC vs CISC debate is still going on despite it being an argument that has been dead for well over 20 years....

I (clam) messed up https://chipsandcheese.com/2024/01/20/inside-qualcomms-adreno-530-a-small-mobile-igpu/ because I thought it ran in wave64 based on testing the wrong thing and reading Mesa code.

I now think it runs in wave32 mode and has two scheduling partitions per SP. That's based on tests I wrote to investigate Adreno 730 (which is a really interesting architecture in its own right), which I went back and ran on Adreno 530.

The first is a simple divergence penalty test, which measures throughput with OpenCL threads being coherent at different granularity. It works as expected and shows Pascal gets best throughput with 32 or higher, and GCN does so with 64 or higher. Adreno gets better throughput with 32 or higher, suggesting wave32
