Test results for AMD Ryzen
Author: Agner Date: 2017-07-13 09:45
There is an advantage only if instruction fetch and decoding is the bottleneck, which is often the case. Future processors will probably have higher throughput for 512 bit instructions. This happens every time they increase the vector size. The first processor to support a new vector size always has inferior performance. This makes sense because there is very little software on the market to support the new vector size.
