EVGA GeForce GTX 680 Classified Review: Pushing GTX 680 To Its Peak
by Ryan Smith on July 20, 2012 12:00 PM ESTCrysis, Metro, DiRT 3, Shogun 2, & Batman
Since the GTX 680 Classified doesn’t bring anything new to the table architecturally, we’ll keep our commentary on its stock performance brief. At stock it’s much like any other overclocked GTX 680 (factory or otherwise), with the only real room for differentiation being the greater amount of RAM and the higher power target. In practice the greater amount of RAM doesn’t make much of a difference in our single-GPU tests, as that much RAM is far more beneficial for the ultra-high resolutions of multi-monitor gaming, at which point you’re going to need a second card to provide the necessary horsepower.
The higher default power target on the other hand is quite interesting. The GTX 680 Classified will hit its top boost bin almost all of the time thanks to the generous power target, something the reference GTX 680 can have trouble with even at stock. So although reference cards can be overclocked to this level, it doesn’t necessarily mean they’ll match the GTX 680 Classified’s boost clocks in that state.
Starting off as always in Crysis, there’s actually not much to see. Since the reference GTX 680 is already memory bandwidth limited here and since the GTX 680 Classified doesn’t have a memory overclock, the factory core overclock does very little for its performance here.
Metro isn’t a title that we’ve previously considered to be memory bandwidth limited, but given its GPU-crushing nature like Crysis (and the fact that the 7970GE does so well here), maybe we should take that into consideration. The GTX 680C picks up 7% here at 2560, which is decent but it’s less than what the factory overclock can provide when the GPU can fully stretch its legs.
Now when the GTX 680 Classified can stretch its legs in a GPU-bound situation, we see the full impact of that factory overclock. With DiRT 3 it picks up the full 10% performance improvement the factory overclock is capable of providing.
Things also look good with Shogun 2 at 2560, with another 10% gain. On the other hand 5760 only picks up 7%.
Batman on the other hand doesn’t do the GTX 680 Classified any favors, which is a bit odd. 3-5% just isn’t what you expect here, since there’s no real evidence that the game is CPU or memory bandwidth bottlenecked.

i'm kinda more interested in 8xMSAA or 4xSSAA...Ryan Smith - Saturday, July 21, 2012 - link
Ahh, okay, I see what you mean.So the short answer is that the memory requirements on Ultra are so high that we wouldn't be able to test most of our previous-generation 1GB cards at 1920 if we used it. I did want to have Ultra in there somewhere so that was the compromise I had to make to balance that with the need for a useful test at 1920.
Though I will agree that it's unorthodox.

At the same time that would be pretty useful to see if GTX570/580 run out of VRAM in Shogun with Ultra settings at 1080P. What if GTX660Ti only has 1.5GB of VRAM? We'd want to know if it's already starting to become a bare minimum in games :)CeriseCogburn - Tuesday, July 24, 2012 - link
The 570 and 580 don't run out, but the 5750, 5870, and 6950 1gb and 6970 1gb do. A lot of amd fans have those 1gb cards because as usual, the amd fan is all about scrimping pennies and claiming they have the best anyway. Sad, isn't it.Sadder is the 1920x1200 rez they use here, which allows crap amd cards to lose by less when most people have 1920x1080 where nVidia stomps on amd ever harder, because as usual, amd fan boys are hacking away over pennies and buy the much cheaper and far more common 1920x1080 monitors instead of 1920x1200, saving $50 minimum amd more like $100+.
So, amd loses, all around, again, as usual.

There is no "1200p"Catch-phrases like "720p" and "1080p" refer to television formats; they aren't just the vertical pixel number. 1920x1200 is not a television standard, and the "p" is superfluous.

While EVGA's cooler is an improvement over stock, I wonder how a capable card like this would perform if paired with an high performance cooler like the Arctic Accelero Xtreme III. Kepler-based cards drop their boost clocks above 70C to compensate for increased leakage, so it would be interesting to see how fast this card could get while staying below that mark. Even at maximum RPMs the fans would probably be quieter than this one.pandemonium - Saturday, July 21, 2012 - link
I can't understand where the market for this card is. Wait, nevermind. I forgot how many nVidia fanbois there are out there...RussianSensation - Saturday, July 21, 2012 - link
So true. $740 GTX680 with a volt-mod kit vs. $450 HD7970 that overclocks on stock voltage to 1.175V and gives the same performance. NV marketing machine FTW!CeriseCogburn - Tuesday, July 24, 2012 - link
Amd cards never give the same performance as they lack so many features.you can perhaps, if you're lucky, get an fps only equivlanet in a few old games, or a hacked equivalent with crappy IQ that I'm sure you cannot see anyway, and in that case your power/performance is a big fat loser too - we cannot suddenly forget that for just this latest round when it was the most important point ever made for several years just prior now can we...
pffffft !~

Not with this card. When you buy reference for liquid cooling then you can't go wrong with EVGA. Best cards around. When you buy EVGA Hydrocopper - you can't go wrong. But EVGA Classified are usually only highly overpriced reference designs. Yes there are tweaks here and there, but for max performance [air cooler] out of GTX family most people [including my humble person] go to MSI TwinFrozr3 Lighting/EX.or Asus 3 slot bricks (name escapes me).Lately EVGA sliding with theirs top offerings. SR-X motherboard is cruel joke when compared to ASUS dual CPU creation and now this. Another misfire.
But I think EVGA doesn't care too much. They have devoted customers who buy everything EVGA without thinking...
