Note: Releases R8 and R8x have been updated to R8z to address additional compatibility issues.
Note2: ARM64 support has shipped with the R9 release.
We are pleased to release R8z (version 31.60) update for Sandra 20/21 with the following changes:
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.
Please don’t forget to submit benchmarks results to the Official SiSoftware Ranker! Many thanks for your continued support.
And please, don’t forget small ISVs like ourselves in these very challenging times. Please buy a copy of Sandra if you find our software useful. Your custom means everything to us!
