WebGL2 HALF FLOAT matrix multiplication C = A x B (SGEMM) benchmark. Fixed random A, B 4096x4096 arrays are used for calculations, therefore You can set new N = M = K value (up to N=4096, multiple of 4). FLOPS = 2 N3/ time.
GeForce RTX 2070, N = 4096 1600 GFLOPS (RGBA16F) 835 GFLOPS (RGBA32F).
I re-run all programs many times (press "Run" button) and try to choose "highest representative" values.
