How was KNL too slow for HPC, like Cori? It does need to be the right sort of HPC that can use the SIMD and/or benefit from the memory bandwidth. Just the large core count (for the time and Intel) helps with MPI communication, keeping more of it local, or all of it for small enough jobs. However, we did have 64-core Bulldozers rather earlier.
