Final Thoughts

If my final thoughts start sounding like a broken record, it’s because once again a set of NVIDIA & AMD product launches have resulted in a pair of similarly performing products.

The crux of the matter is that NVIDIA and AMD have significantly different architectures, and once again this has resulted in cards that are quite equal on average but are all over the place in individual games and applications. If we just look at the mean performance lead/loss for all games at 2560, the GTX 590 is within 1% of the 6990; however, within those games there’s a great deal of variance. The GTX 590 does extremely well in Civilization V as we’d expect, along with DIRT 2, Mass Effect 2, and HAWX. Meanwhile in Crysis, BattleForge, and especially STALKER the GTX 590 comes up very short. Thus choosing the most appropriate card is heavily reliant what games are going to be played on it, and as a result there is no one card that can be crowned king.

Of the games NVIDIA does well in, only Civ5 is a game we’d classify as highly demanding; the rest are games where the GTX 590 is winning, but it’s also getting 100+ frames per second. Meanwhile on the games AMD does well at the average framerate is much lower, and all of the games are what we’d consider demanding. Past performance does not perfectly predict future performance, but there’s a good chance the 6990 is going to have a similar lead on future, similarly intensive games (at least as long as extreme tessellation isn’t a factor). So if you had to choose a card based on planning for future use as opposed to current games, the 6990 is probably the better choice from a performance perspective. Otherwise if you’re choosing based off of games you’d play today, you need to look at the individual games.

With that said, the wildcard right now is noise. Dual-GPU cards are loud, but the GTX 590 ends up being the quieter of the two by quite a bit; the poor showing of the 6990 ends up making the GTX 590 look a lot more reasonable than it necessarily is. The situation is a lot like the launch of the GTX 480, where we saw the GTX 480 take the performance crown, but at the cost of noise. The 6990’s performance advantage in shader-intensive games goes hand-in-hand with a much louder fan; whether this is a suitable tradeoff is going to be up to you to decide.

Ultimately we’re still looking at niche products here, so we shouldn’t lose sight of that fact. A pair of single-GPU cards in SLI/CF is still going to be faster and a bit quieter if not a bit more power hungry, all for the same price or less. The GTX 590 corrects the 6990’s biggest disadvantage versus a pair of single-GPU cards, but it ends up being no faster on average than a pair of $280 6950s, and slower than a pair of $350 GTX 570s. At the end of the day the only thing really threatened here is the GTX 580 SLI; while it’s bar none the fastest dual-GPU setup there is, at $1000 for a pair of the cards a quad-GPU setup is only another $400. For everything else, as was the case with the Radeon HD 6990, it’s a matter of deciding whether you want two video cards on one PCB or two PCBs.

Quickly, let's also touch upon factory overclocked/premium cards, since we had the chance to look at one today with the EVGA GeForce GTX 590 Classified. EVGA’s factory overclock isn’t anything special, and indeed if it were much less it wouldn’t even be worth the time to benchmark. Still, EVGA is charging 4% more for about as much of a performance increase, and then is coupling that with a lifetime warranty; ignore the pack-in items and you have your usual EVGA value-added fare, and all told it’s a reasonable deal, particularly when most other GTX 590s don’t come with that kind of warranty. Meanwhile EVGA’s overclocking utility suite is nice to see as always, though with the changes to OCP (and the inability to see when it kicks in) I’m not convinced GTX 590 is a great choice for end-user overclocking right now.

Update: April 2nd, 2011: Starting with the 267.91 drivers and release 270 drivers, NVIDIA has disabled overvolting on the GTX 590 entirely. This is likely a consequence of several highly-publicized incidents where GTX 590 cards died as a result of overvolting. Although it's unusual to see a card designed to not be overclockable, clearly this is where NVIDIA intends to be.

Finally, there’s still the multi-monitor situation to look at. We’ve only touched on a single monitor at 2560; with Eyefinity and NVIDIA/3D Vision Surround things can certainly change, particularly with the 6990’s extra 512MB of RAM per GPU to better handle higher resolutions. But that is a story for another day, so for that you will have to stay tuned…

    Would this card be better for the P67 platform vs GTX 580's in sli considering you won't get full 16x going the sli route? Reply

    The 16x vs. 8x issue has been beaten to death for years. Long story short, it's not a measurable difference at or below 1920x1080 resolutions and only barely a difference above that. Reply

    Thanks man. Already have one evga 580. Only reason I was considering was for the step up program evga offers (590 for around $200). I have till first part of June to think about it but am leaning towards adding another 580 once the price comes down in a year or two. Reply

    You won't get 16x going the CF route either.....although I agree that it doesn't really matter. Reply

    Comon guys, I would have thought you could have at least had the 6990 and the 590 data points for Crysis 2. Perhaps a short video as well with the new game? :) Reply

    It's unlikely we'll be using Crysis 2 in its current state, but that could always change.

    However if we were to use it, it won't be until the next benchmark refresh.

    Crysis: Warhead will always be the benchmark. Crysis 2 isn't nearly as demanding. It's been dumbed down for consoles, in case you haven't heard. There are no advanced settings available to you through the normal game menu. You have to tweak the CFG file to do so.

    I thought like you, originally. I was thinking: Crysis 2 is gonna set a new bar for performance. But in reality, it's not even close to the original in terms of detail level.

    I know I can be annoying, but I checked it myself and the built in benchmark in Civ V really favours nVidia cards. In the real world scenario the situation is almost upside down. I got a reply from one of the reviewers last time that it provides quite accurate scores, but I thought that just for the heck of it you'd try and see for yourself that it doesn't at all. I know it's just one game and that benchmarking is a slow work, but in order to keep up the good work you're doing you should at least use the advice and confront it with the reality to stay objective and provide the most accurate scores that really mean sth. I don't mean to undermine you, because I find your articles to be mostly accurate and you're doing a great job. Just use the advice to make this site even better. A lot of writing for a comment, but this time maybe you will see what I'm trying to do. Reply
