Are older CPU's really that slow in cryptonight?
I have a rig with an old Xeon 5645 (2.4 Ghz, 6 core, 12 Mb cache AES, SSE 4.2) that gives 200 H/s with xmr-stak / xmrig.
A tiny mobile i7 7500u 2 cores makes 135 and a Ryzen 1700 around 530.
Are newest CPU's really more efficient using AES, does software use other instructions for cryptonight, or what?
I was really expecting more from a 6 core / 12 Mb CPU, but I already checked, and yes, it's average for this CPU.
I think all of them uses AES, I don't know if there are some revisions that makes it faster, but generally newer CPUs are faster every generation and with better power consumption. For CPU mining try AEON, much better for CPU, hashrate is 4x higher then on XMR and only 2x times higher with GPU.I have a rig with an old Xeon 5645 (2.4 Ghz, 6 core, 12 Mb cache AES, SSE 4.2) that gives 200 H/s with xmr-stak / xmrig.

but the 6 year old fx8120 is still a beast, 420 hash, but it does use more power then new gen cpu's ofcourse.
Impressive. That's why I expected a bit more performance of a 6 core AES CPU.
You should've mentioned that I need to use a keyboard
