It averages time for some iterations of random math operations. So the test measures how fast the LUA interpreter can interpret a set of simple Math operations (and a table insert/remove). I suspect that either the intepreter overhead or some of those operations (power, devision, insert, remove) completely dominate the benchmark. The fast, common operations probably dont have much influence at all.

i think he mesured those numbers in CPU-Z or cinebench, not faf.

This looks like the real answer, but hard to understand what exactly happens there without having a reading-code-skills =\

so yeah your 9900K scored worse than your 3700X according to FAF... which you should disregard entirely because FAF's cpu score is rustic and in no way an authority on what CPU is better... especially when it comes to newer CPUs.

this test at the time it was made didn't account for the world of CPU developing "under-clocking", a technology which allows for saving power and useless cycles dynamically when the CPU isn't doing much. and by today's standards, running FAF's cpu bench is basically not even lifting a pinkie.

It probably just measures how long something takes and converts that into a number. You will never arrive at 0 unless your CPU is infinitely fast.

of course. old one is 6600 non-k, i was at 175ish

new cpu is 136-140 out of the box and 133-135 with a slight overclock.

Did you re-run the benchmark after you got your new CPU?

Current top of the line CPU is 9900K which is having 580 points at a raw single core performance.

I running a 3700X which is 535 points, only 8% slower.

CPU's in lobby rated from 0 to 450, lower the better, and this meter is showing up 3700X as a 133-140

What in the world you need to have, to be at a top 100 in this benchmark of sort?

Thanks.
