For me the git master branch uses 1 and a half core (~130-150% usage). The angrylion-rdp-sse branch uses 2 cores (~200% CPU usage). AVX build, build today.

edit: And I got around 41 VI/s on an 2Ghz i7 (boosts to 3Ghz) in the Funnel Cube Demo.

That sounds right. master branch can still only effectively use 2 cores with multithreading. angrylion-rdp-sse branch changed it so that, effectively, 3 cores can be used.

Haswell/Broadwell/Skylake also run CEN64 a lot faster (clock for clock) than their predecessors. Dolphin observed something similar in this regard.

On a 2.8GHz/3.2GHz (stock/turbo) i7 mobile (dual core, hyperthreaded) Haswell, I currently get about 53-55VI/s on the funnelcube demo.

Make sure you are still passing -multithread when running with angrylion-rdp-sse builds.

Only 3 of the cores are really "busy" (the fourth is just to handle the GUI, render the screen, etc.) For the best performance, you want a true quad core, though -- there's a notable difference between a dual-core hyperthreaded CPU, and one that actually has 4 cores.

In the future, I hope to use fewer cores once I finish the rewrite. The rule of thumb is probably thus: get the highest clocked quad core you can find. If you're on a budget, get the highest clocked dual core with hyperthreading you can find.
Thanks for the clarification I'll go for the best i7 available.

hey guys, am guessing you know about this but putting all this together? wow...

this scales across many many cores...
