GTX 670M vs 670MX vs 675M etc.

For the test I am using Unigine Heaven 2.5. Older version but soon I am going to upgrade to 3.0 which is the latest build I believe.

Here are my results with stock Nvidia settings and stock GTX 670MX



OCed GTX 670 @ 735 core and 1500 MHz memory

Thank you for the post. Very helpful. Good results. I like the fact that you can go that high on the core and I think that your memory can go up to +400 so you can try.

I will try the +1000 memory in games and post some results once I get the chance.

As I understand unigine heaven is a test which completely focuses on the GPU so that the power can be measured more accurately just in that domain. It is not very much CPU dependent and does not overload it. My point is that it shows the true potential of the graphic card and if some frequencies are not stable they will show in unigine first rather than in games. But we will see.

Still 30% overclock on a laptop with normal temperatures is amazing. I wish we were able to play with the voltage and that nVidia / ASUS unlocked the thermal power for +10 or more percent on the card but even this is just amazing.

Thanks dude... It's really impressive, actually... Yeah with Heaven it is very stable so we can push it hard, with games, etc. there could be bugs, driver issues, etc. that affect stability. Going to try3DMark Vantage now. 3DMark11 takes too long...! As for voltages, yeah... that's where I get scared LOL.

GTX 660M 1100mhz (+265) core, 3100mhz (+600) mem 😄
Edit: Tessellation: Moderate to compare with my benches previously posted.
Phew... For a second I thought I had no tessellation because I fried my card or something...

This stuff is more complicated than I thought. So if I press "Default" in EVGA Precision, is it going to restore the default gpu settings?

[gokica]

It is all about moving the sliders and test. The temperatures are quite normal at maximum allowed overclock. And yes, pressing default applies stock frequencies automatically. In my case nVidia Inspector and a GPU frequency of 800MHz yields lower results comparing to +135 and +1000MHz on the memory.

Great results and a very nice overclock. How high is the ASIC quality of your chip in GPU-Z? It seems like a good bin to me.

Cheers... It is 72% ASIC Quality. What does this mean?

3DMark Vantage and 3Dmark 11:



FWIW now running 660M for Folding@Home 1200mhz core, 2700mhz mem... I think my GPU core is OK but the mem is sensitive. Still, not sure in CUDA how "artifacting" is handled, I wonder if it slows down the folding if clocked too high because errors(artifacts) have to be recalculated.
