SiSoftware Sandra 20/21-R8x – New Memory & Cache Benchmarks

Note: Releases R8 and R8x have been updated to R8z to address additional compatibility issues.

We are pleased to release R8z (version 31.60) update for Sandra 20/21 with the following changes:

Sandra 20/21 Press Release

We are continuing to make multi-threading improvements across all benchmarks and other modules, including hybrid big/LITTLE architectures, both x86/x64 and ARM/ARM64. Further scheduling and benchmark optimisations are ongoing.

We have a brand-new dynamic workload scheduler for the memory and cache bandwidth benchmarks which takes into account each core’s performance – similar to the processor benchmarks workload scheduler. This way the bandwidth of different cores (big & LITTLE) can be measured in parallel. This works both on the standard x86/x64 platform as well as traditional ARM/ARM64 big/LITTLE platforms.

Hardware Support, Updates & Fixes

  • Memory & Cache Benchmarks
    • Dynamic bandwidth workload allocator for big/LITTLE arch (e.g. ARM, Intel “AlderLake”)
