> Slightly, the older tech is 64 threads/lanes per warp/wavefront. Newer ones are 32 by default but 64 if desired. AMD GCN was 64 threads/wavefront. NVidia always was 32 threads/warp. AMD's newest consumer cards RDNA and RDNA2 are 32 threads/wavefront. However, GCN lives on with CDNA (MI200 supercomputer chips), with 64 threads/wavefront architecture. |
