Ho do you achieve 25+ mh/s iterations, comparing in google table (Timelord (MH/s)? My i9 7900x with 20 threads getting just 2.6 mh/s with just used 2 core by default. MMX-node 0.9.14 / Ubuntu 22.10 / 64Gb RAM / Nvidia 4090

intel Core x7900

Your processor is 16 years old.

Core i9 7900x

Thank you for clarifying.

The single-core performance of Skylake was great in 2015 but doesn't hold up well against Zen 3 and Golden Cove and newer. Furthermore it's missing some specific instructions found in newer architectures that the TL process can leverage to greatly accelerate its processing. The TL "high scores" all belong to Raptor Cove at the moment.

Yep, with AMD Ryzen 9 5950x at 5100 GHz (2 core) have 25.8mh/s in windows binary and about 22mh/s with linux v0.9.14 It seems linux code need better optimizations. Adding more parallel cores in code does not help much :)

Core i9 7900x

I9 7900x IS in fact 10 cores (20 threads) per Intel. Or the same as my ancient E5-2680 v2 CPUs of the same generation. It might only be USING 2 of those cores when running a Timelord, but the other cores are there.

But it's single core performance is horrible compared to anything current, and has ZERO support for SHA extensions - and that lack of SHA extensions is the killer in VDF work (that support showed up a FEW generations later).
