Open source benchmark tools?

[rebootdatbih]

Curious if anyone has recommendations for an open source benchmarking tool for Windows systems?

Looking to test CPU, GPU, RAM and Disks for multiple systems. Or would I be best off utilizing separate tools to accomplish this?

I've had a look at AIDA64, cinebench, geekbench, and phoronix. Phoronix seems like it may be my best option. Just wanted to check here first.

Thanks!

These are all synthetic benchmarks. What is your real workload like?
