Suite à l’arrivée des processeurs AMD Ryzen, l ‘éditeur SiSoftware a décidé de mettre à jour son logiciel SANDRA dont la version 2017 vient tout juste de paraître. En priorité, cette nouvelle version prend donc en charge l’architecture Ryzen mais elle apporte également plusieurs autres changements comme on peut le voir ci-dessous.

Maj : la version 2017.04.24.12 remplace la 2017.03.24.11 lancée la semaine dernière. Elle apporte simplement quelques corrections mineures.
* New fresh look!
Brand-new high-resolution icons for all modules and benchmarks at 256×256 pixels for all operating systems (including Windows 7) with Aero/transparency support for Windows 7 as well as future Windows 10/Neon!
* Hardware support for AMD Ryzen architecture
– Benchmark modifications with respect to non-zero (0), non-constant value buffers (memory bandwidth, cache bandwidth, multi-core bandwidth, crypto bandwidth). While this is a departure from standard STREAM, I personally believe it is a good idea ensuring memory pages are distinct and thus preventing data compression and optimisation (read/write).
* More AVX512 code-paths for future arch
– CPU Crypto hashing (SHA2-512, SHA2-256, SHA1) multi-buffer
– Memory and Cache bandwidth AVX512 both 256-bit and 512-bit transfers (depending on hardware).
– Transition to newest VC++ 2017 with preliminary support for AVX512 across benchmarks.
* GPGPU Cuda 8.x SDK support
– Support and optimisation for Pascal arch.
* CPU Image Processing and GPGPU Image Processing enhancements
– Wide Colour (10-bit bits-per-channel/30-bit total) image support
– Half Float (16-bit float) processing in addition to normal 32-bit float processing. (for 8-bit bbc it is sufficient)
* Maintained System benchmark: Overall Score 2016/Platinum
– As we’ve added just about all the benchmarks we can without running for hours, we are keeping the Overall Score unchanged for this release. We are planning to change it for the next major version.
