Hardware Support

With support for AVX2, AVX-512, and VNNI instruction sets, the DeepSparse Engine is validated to work on x86 Intel (Haswell generation and later) and AMD CPUs running Linux. Mac and Windows require running Linux in a Docker or virtual machine.

Here is a table detailing specific support for some algorithms over different microarchitectures:

x86 Extension Microarchitectures Activation Sparsity Kernel Sparsity Sparse Quantization
AMD AVX2 Zen 2, Zen 3 not supported optimized not supported
Intel AVX2 Haswell, Broadwell, and newer not supported optimized not supported
Intel AVX-512 Skylake Cannon Lake, and newer optimized optimized emulated
Intel AVX-512 VNNI (DL Boost) Cascade Lake. Ice Lake, Cooper Lake, Tiger Lake optimized optimized optimized
