I like how this only has that single 8-pin power connector and the rest through PCIe. I'm all for less cables, coming from SLI...

OC looks good on this one, best out of what Hilbert tested so far. Likely silicon lottery though.

For the OC or generic ? I'll see if I can fit in the RPM plot into the AB screenshot.

Update: done, will include actual RPM values in the upcoming reviews.

Thanks from me also Hilbert

That was the one thing missing from these recent reviews , a lot of people on the web really liked that your reviews were one ones to include the RPM screenshot , the RPM/TEMP connection can tell an awful lot about a card especially to people like me who like quiet and cool systems even when gaming.

I personally bought the MSI 780 Gaming on the spot when i read your review and saw that the max RPM was 1132 even when the card was stressed.

I don't know , the power delivery and core clock certainly looks more stable on the MSI to me , the extra power and phases must be doing something

Hi Hilbert,

i have a question regarding the boost? Some sites, and users, are reporting that the the gpu only works (boosts) properly when the card is cold and that after 15 minutes or more, the card starts to trottle heavily and the boost almost disappears, becoming meaningless. Some sites are even starting to warn up cards for 30 minutes and then do the tests to make sure the boost doesn´t influence the results wrongly. And a few are starting to suggest (indirectly) that the boost is only intended to "cheat" on benchmarks, so the cards results are higher than they should.

My question is if you have found any evidence that confirms or contradicts this issue???

Thanks!

So if you look at the temp values in the chart above your post you can see that indeed I perform a warm-up cycle.

Thus far I have not been able seen active down-throttling on the boost values with long term usage. Typically imho that would/could happen with the founder editions as these cards have a temperature limiter set at roughly 80 degrees C, and it in fact that cooler reaches that number. At that moment the hardware will try and protect itself by lowering clock/voltage value to get closer to that 'safe' 80 degrees C again.

The AIB card however all have cooling well below that thermal threshold of 80 degrees C, since these cards run say 10 degrees C lower, they will (should) not run into that issue. That boost clock will only go down if the graphics card measures a valid reason for it. But it is complicated with GPU Boost 3.0, I'll give you that. Nvidia has so many sensors up these days.

In short - Thus far I have seen very little boost variation at the end of a two hour benchmark stretch. I am not saying it can't happen. But the chances with properly cooled AIB card pretty much should prohibit that behavior.

Also and let me add this, you need to keep things in perspective. If the card did reach a thermal limit and adapts by downclocking 50 MHz on the boost clock ... honestly you are not going to notice it in performance. You need more orders of magnitude for that say 100~150 MHz would result into maybe a 2 FPS lower framerate on a 60 FPS average.
