- R14e/g 30.96 (3-Feb-2021): Optimisations to AMD Ryzen 5000-series and older.
- R14c 30.95 (31-Jan-2021): Resolves possible crash issues on older AMD (Kabini, etc.) systems.
- R14b 30.94 (27-Jan-2021): Resolves issues on future Intel Rocketlake (RKL)/Alderlake (ADL) systems.
- R14a 30.93 (26-Jan-2021): Resolves issues on older Intel Haswell (HSW)/Broadwell (BRW) systems.
As we continuing to move towards Sandra 20/21 release, we are pleased to release R14x (version 30.9x) update for Sandra 20/20 (2020) with the following changes:
- Preliminary Intel Alderlake (ADL) support; optimised RocketLake (RKL) support
- Preliminary Intel PCH series 500, 600 support
- Preliminary AMD Ryzen (Zen3 Mobile) support; optimised Zen3 (series 5000) support
- Preliminary Zhaoxin/Centaur KX-5000, KX-6000, KX+ support
- Preliminary Hygon/AMD (Ryzen-like) support
- Resolved CPU speed detection for some Atom “Goldmont” SoCs
- Preliminary big/LITTLE hybrid system workload optimisation*
- Select only “big”, only “LITTLE” or “All” cores to benchmark
big/LITTLE Hybrid Architecture (aka “heterogeneous multi-processing”)
As with any new technology, it will naturally require operating system (scheduler) support and may go through various iterations. Do note that as we’ve discussed in our 2015 (!) article – ARM big.LITTLE: The trouble with heterogeneous multi-processing: when 4 are better than 8 (or when 8 is not always the “lucky” number) – software (including benchmarks) using all cores (big & LITTLE) may have trouble correctly assigning workloads and thus not use such processors optimally.
As Sandra uses its own scheduler to assign (benchmarking) threads to logical cores, we have updated it to allow users to benchmarks not only “All Threads (MT)” and “Only Cores (MC)” but also “Only big Cores (bMC)” and “Only LITTLE Cores (LMC)“. This way you can compare and contrast the various cores performance without BIOS/firmware changes.
The (benchmark) workload scheduler also had to be updated to allow per-thread workload – with threads scheduled on LITTLE cores assigned less work and threads on big cores assigned more work depending on their relative performance.
Please note big and LITTLE cores may not support the same instructions sets; if running on ALL cores, only the instruction sets available on all cores will be used. Future versions of Sandra may be able to use different instruction sets depending on the core tested within the same test.
Note: This advanced information is subject to change pending hardware and software releases and updates.
