Matrix multiplication. Naive shader v.1i benchmark

WebGL2-compute based NxN matrix multiplication C = A x B Naive shader v.1 benchmark. Fixed random A, B 1024x1024 buffers are used for calculations, therefore You can set new N value (up to N=1024, multiple of TS). Shaders with tile sizes (local_size_x,y) TS = 8, 16, 32 are precompiled. it - number of iterations. FLOPS = 2 N3it / time. Random CGPU and CGPU - CCPU are shown.

N= TS= it=

Intel i3-8100     33.4 GFLOPS (N=1024, TS=32).

I re-run all programs many times (press "Run" button) and try to choose "representative" values. Results differ very much on different GPUs.
