Sandra 20/21 Press Release

We are releasing more benchmark updates for ARM/Arm64 after additional testing with support for additional hardware as tested in the field.

We are also announcing the development of the Apple Mac (OS X) version of Sandra – to benchmark those M1-class Arm64 processors! Now that we converted the code to Arm64, we can just use it on other platforms, e.g. Android, Mac, etc. We hope to be going public by the end of the year (2022 that is 😉

Is x86 dead? Well, that is for you, the users/customers to decide. Vote now! 😉

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 (independent software vendors) 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!
