I'm not surprised expecting to beat implementations of the basic Goto strategy for BLAS didn't turn out well. BLIS only needs a single, pared-down GEMM kernel for level3, and maybe one for TRSM. (It doesn't currently have GPU support, but I think there was an implementation mentioned in an old paper.)
