i7 920 rendering faster than i7 4770


Recommended Posts

Same scene is rendering 30% faster on my i7 920 than on my i7 4770k.

 

Both machines have dymamic memory set at 6000.

 

Win. resource monitor small CPU window (hor blue line) on the right showed the 920 cpu at 70% for the duration of render while the 4770k cpu was at 20% . ????

 

Task manager window showed 100% for both.

 

The windows performance experience is rating the processor 920 at 7.4; the 4770k is rated at 5.1.

 

Any idea what might be causing this? Any programs you might recommend to accurately gauge cpu performance?

 

Thanks.

The 4770K should have an almost 70% higher multicore and 75% higher single core performance. So i think there must be something wrong with your setup...

Did you check your Bios settings? Is this a clean windows installation with all drivers? (but i think this is so far off, this can't be a driver issue...)

I took off the cooler and cleaned off both surfaces - am going to re-paste. Cooler was quiet and smooth.

 

I'm pretty sure HT is enabled on the bios. I'm looking for a performance tester app to see if it's just running slow in general.

 

Like I said, windows is giving the 4770k cpu a 5.1 rating while the 920 is getting a 7.4.

 

Something ain't right.

You can try cinebench and compare the results:

And some additional tools to see whats going on:
