→CPW GPU article: new section
My own conclusions are:
* TeraScale has VLIW design.
* GCN has 16 wide SIMD, executing a Wavefront of 64 threads over 4 cycles.
* RDNA has 32 wide SIMD, executing a Wavefront:32 over 1 cycle and Wavefront:64 over two cycles.
== SIMD + Scalar Unit ==
It seems every SIMD unit has one scalar unit on GPU architectures, executing things like branches and branch-conditions or special functions the SIMD ALUs are not capable of.

== embedded CPU controller ==
It is not documented in the white paperswhitepapers, but it seems that every discrete GPU has an embedded CPU controller (e.g. Nvidia Falcon) who (speculation) launches the kernels.
[[User:Smatovic|Smatovic]] ([[User talk:Smatovic|talk]]) 1110:4836, 18 22 April 2021 (CEST) == CPW GPU article == A suggestion of mine, keep this GPU article as an generalized overview of GPUs, with incremental updates for different frameworks and architectures. GPUs and GPGPU is a moving target with different platforms offering new feature sets, better open own articles for things like GPGPU, SIMT, CUDA, ROCm, oneAPI, Metal or simply link to Wikipedia containing the newest specs and infos.
