Hi @allnes thanks for the PR, could you attach benchdnn test cases where this new heuristic is beneficial and the performance improvements you seen on what machine? Thank you! |

Description
This PR updates the heuristic for selecting the Winograd convolution algorithm. In the new version, devices with more than 28 cores (primarily servers) will no longer choose this convolution. However, for devices such as MacBooks, Raspberry Pi, and other similar hardware, experiments show speedups on a range of networks without the condition
src_md.dims[2] > 112orsrc_md.dims[3] > 112.This heuristic has already been applied in OpenVINO
