Changes

* Tesla has 8 wide SIMD, executing a Warp of 32 threads over 4 cycles.

* Fermi has 16 wide SIMD, executing a Warp of 32 threads over 2 cycles.

* Kepler is somehow odd, not sure how the compute units are partitioned.

* Maxwell and Pascal have 32 wide SIMD, executing a Warp of 32 threads over 1 cycle.

* Volta and Turing seem to have 16 wide FPU SIMDs, but my own experiments show 32 wide VALU.

According to AMD papers It seems every SIMD unit has one scalar uniton GPU architectures, Nvidia seems to have SFUs, executing things like branch-conditions or special function unitsfunctions the SIMD ALUs are not capable of.

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]]) 10:36, 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.
