3770K Intelburn GFlops question

post #1 of 10
Thread Starter 
Both with 2.52 and 2.53 versions of Intelburn I am getting around 100 GFlops with 3770K at 4600 MHz. (with 2.50 version I got 60 GFlops)
These numbers are significantly lower than numbers I was getting with my overclocked 2500K.

What is going on?

At least - are you getting the same numbers as I do?

What is going on?

Maybe linx is not optimized yet?

I remember 2500K didnt run well on linx coz of no AVX support.

I get 106 GFLOPs at 4.6GHz on my 3770k.

Not really an accurate test though and really shouldn't be used to measure a CPU's performance.

Can 106 vs 100 be caused just by memory frequency - 1866 vs. 1600?

It can be caused by a lot of things, IBT tests more than just the processor.

I suggest you stop using IBT as a way to measure CPU speed, use a real CPU benchmark.

Your running it on a i7 tongue.gif . Turn off HT and watch those Gflops sore! 2700k with Ht on gets around 114 and with Ht off gets 135 with 5ghz. Try turning Ht off and see what you get.

I turned HT off and I got 118. This is weird. I thought HT brings cca 20% IMPROVEMENT in performance!

Improvement in some applications. Intel Burn Test isn't indicative of anything in real life, it just loads the FPU with as many operations as possible.
