SiSoftware Sandra 20/21-R9z – Updated Arm64 Support (Apple M1, Microsoft SQ, Qualcomm Kryo)

We are pleased to release R9z (version 31.73) update for Sandra 20/21 with the following changes:

Sandra 20/21 Press Release

We are releasing a pretty significant benchmark update for ARM/Arm64 after additional testing with support for additional hardware as tested in the field.

We are continuing to make multi-threading improvements across all benchmarks and other modules, including hybrid (big/LITTLE, DynamiQ) 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 big/LITTLE platforms.

Please don’t forget to submit benchmark 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!
