A new generation of GPUs from Nvidia and AMD has hit the streets. Both camps are offering incredible performance and the widest array of features ever before seen in graphics cards. But, inevitably, each side brings its own unique strengths and weaknesses. What better way to determine the performance champ than by letting this season’s new crop of cards duke it out in the various price categories?
On one side is AMD, the self-proclaimed master of efficiency, looking to hold onto the glory it grabbed when it shipped the original Radeon HD 5870—a surprise contender that knocked former champ Nvidia to the canvas at the time by offering DirectX 11 feature sets at impressive performance levels without requiring a nuclear reactor to power it.
On the other side is Nvidia, looking to score a comeback. When Nvidia finally shipped its long-awaited Fermi, it managed to retake the performance crown, but with an asterisk next to the record, since it was forced to ship an incomplete chip that required massive power draws. Even then, AMD’s GPUs stayed close, while its dual-GPU HD 5970 dominated performance overall—but only when games took advantage of AMD’s CrossFire X dual-GPU capability.
Now it’s rematch time—a day of reckoning between the shiny, redesigned, and ready-to-rumble Fermis from Nvidia and AMD’s new Radeon HD 6000 series. While Nvidia’s new parts are streamlined versions of the original Fermi, more efficient and full-featured, AMD’s new GPUs have been completely re-architected from scratch. Can new AMD designs deliver a winning blow to Nvidia’s modernized GPUs?
The fight card includes battles in every price class, featuring a representative selection of cards. Contenders will be hit with a boatload of different games and benchmarks, as well as power-draw tests.
Whether they end in close calls or clear KOs, the results of these bouts will determine the videocard you choose for your next rig. Let’s take this party ringside, shall we?
The Technical Decision
What features and capabilities to look for in today’s graphics contenders
If you’re looking for a graphics card today, the decision is more difficult than ever. The two primary suppliers of graphics processors, AMD and Nvidia, have taken decidedly different paths, even as they add more robust support for new graphics and GPU-compute programming interfaces.
DirectX 11
Both AMD and Nvidia support Microsoft’s latest DirectX 11 graphics standard. So far, all DirectX 11 games have run well on both, though some run faster on Nvidia and others faster on AMD. So, you can feel comfortable that either AMD or Nvidia should be fine if you’re looking to run the latest games.
Both AMD and Nvidia are strong players when it comes to DX11 games.
Display Support
On the AMD side, the Radeon HD 6000 line of graphics chips continues to support a minimum of three displays with a single card, just as the older HD 5000 series did. However, all HD 6000 cards have DisplayPort 1.2 built in. What that means is that monitors with DisplayPort 1.2 support can be daisy-chained, so that one card can drive up to six LCD panels. Nvidia’s support for DisplayPort has been lukewarm on consumer graphics cards, but individual card manufacturers have occasionally added DisplayPort connectors. Almost all monitors still ship with DVI connectors, though, so if you’re running one or two monitors, you’re in good shape with a single Nvidia card.
Stereoscopic 3D
AMD has just begun adding stereoscopic 3D capability; the new Radeon HD 6000 series cards support stereoscopic 3D. In both games and Blu-ray movies, though, glasses must be obtained from third parties. Nvidia’s 3DVision offers robust stereoscopic 3D support, provided you’ve also got a PC monitor capable of running at the required 120Hz refresh rate. In addition, if you’re running an SLI setup, you can use 3DVision across three monitors, and the effect can be pretty startling. A system with an Nvidia card can connect to an HDTV and allow that TV’s native stereoscopic capability to work with the PC.
Nvidia has a clear lead in terms of 3D movies and games. AMD needs to catch up.
GPU Compute
If you’re into GPU-compute applications, Nvidia still has the edge here. While newer applications are moving toward multi-vendor standards like DirectCompute and OpenCL, a large library of applications exists for Nvidia’s proprietary CUDA GPU-compute architecture, including the recently released Adobe Premiere Pro CS5’s Mercury Playback Engine.
Physics
Nvidia has worked mightily to get game programmers to incorporate its PhysX technology, but only a few games really support it well. We’re starting to see more open APIs that support OpenCL, like Bullet Physics, arrive on the scene. Already, 3DMark 2011 is shipping with Bullet Physics support, and it’s likely we’ll see a variety of new games ship with Bullet Physics.
Power Consumption
Nvidia’s made some substantial strides in improving power efficiency, but cards using AMD GPUs still tend to consume less power. If you can save $50 a year in electricity, that could mean an additional game you can buy.
HD Video Encoding
While both cards support HD video decoding, AMD’s third-generation Unified Video Decoder (UVD3) offers hardware decoding of key HD codecs, including VC-1 and H.264. It also handles MPEG-2 and MPEG-4 Part 2, including DivX and xVid in hardware. AMD also supports hardware-accelerated transcoding in its fixed-function UVD3, with the ability to convert H.264 and MPEG-2 1080p streams to a different H.264 or MPEG-2 target bitrate and resolution.

I bought an AMD 6850 last November for my new build, and it's great. I can play any game I want, and I've even played Crysis at 1080p with High settings! This card has well exceeded my expectations. Highly reccomended. but is very bad

The 460 better than the 5770?
Not hardly.
1st there is the heat issue.
Then there is the ATi issue. We all know that ATi drivers sucked. I consistently had to roll back my drivers just to play old games because the drivers wouldn't work with the game engines'. But now AMD is making it up to us ATi guys in so so so many ways.
Starting with Catalyst. Before I got my 5770 all I read and heard from friends was "go to MSi and download their afterburner program..." which is a solid option still, but AMD has really simplified Catalyst. My grand parents could adjust anything to their hearts content if they were alive and well. My mother who is not technically savvy has no issues with it at all. Though like all moms will probably ask if there is a question that comes up and I can walk here through it step by step. Try that with Windows. lol
Then you have PhysX. NVidia you dirty bird you cornered market share from ATi for so long because game manufacturers rushed out and started coding to meet this demand. Still there are quite a few developers that don't use the technology. Doesn't matter anyway because AMD came up with BullitPhysX to shrink the gap even further.
And now you have Game Giant source company Steam giving their customers another avenue to update their drivers. Oh?, what? Not NVidia friendly? Bout damn time.
The coold thing about AMD being in the mix, is they have the pockets to compete with NVidia and put things on a level playing field. Sure there is still a performance gap when you move up the GPU chain, but at the entry point to Enthusiast Cards 5770 has it over the 460 in spades. Price, performance gap is in a dead heat and I don't have to introduce the rest of my components to an ice bath after every gaming session. Walk the plank Fermi.

I love you MacPC, but what happened? Why would you use the nVidia 460 at the 250 price point and not the GTX 560 Ti? It's been out for almost a month now. I plan on gaming at 1080p, and im torn between a 560, with SLI in the future, or a 570. Maybe I should bite the bullet, spend the extra 150, and go for the 580...

Excellent article! I always love reading and comparing specs on video cards and this seems like a "who's who" of video cards.
My one bone: I think the 6850/460 (768MB) & the 6870/460 (1GB) comparisons are a tad unfair to the nvidia cards. I think the 6850 should have been compared to the 460 (1GB); the 6870 vs. the 470. The price points are little closer and I think the comparisons would have been much closer.
Then again, anyone that gets either 460, or the 6850/6870 should be happy with their purchase. They are all dynamite cards with an excellent price/performance ratio!

How is it unfair?
If you want to make a point about Fairness, how about pointing out that Companies like EA still code to give NVidia an unfair advantage over their competition. That right there shrank the Video Card market to two chip manufacturers. NVidia and ATi.
Can you imagine if ATi had just gone the way of the Dodo without AMD to come in and pick up the pieces? Do you understand we were VERY close to having a monopoly in the Graphics market? One that people would have been forced to buy NVidia regardless if they liked it or not?
All because NVidia works better when it can take advantage of the software that Game developers built into their games. If this is a coinkydink I'll eat my 5770 without condiment.
All things being equal, yes it would be unfair to compare the 460 to the 6850 and the 6870, but AMD didn't do anything other than address their tesselation issues. While NVidia addressed what they didn't complete with the initial Fermi.
So now you tell me, which is unfair?
Having the market cowtow to one manufacturer for so long and comparing their cards which have the unfair advantage to anyone else.
Or comparing both on an equal footing? If 3D is used then I can see the problem since Fermi isn't a 3D card. But I've got this issue and I didn't see any 3D benches being used in the argument. Not even in the way that PhysX was used for so long, even though a only a handful of developers were using the technology.
I don't see how people can cry foul over this comparison.

My first post as a newbie :)
Thanks for excellent article, great job but still I've few doubts left:
1) which is faster/powerful? 6950 or 5870? (thanks to ati's wierd numbering!)
2) I read at many places that Sapphire 5850 Toxic is the best card available compared to other makers in its class. Say, we could OC the card etc. How does Toxic 5850 fare against reference 6950?
3) What are the equivalent of the above cards in nvidia? Please mention only if they draw less power and generate less noise.
4) How good is 3D support in 6950/570 gtx? (3 LCDs or connecting to a large display such as a Sony TV 46" or 50" or above).
5) For only one card, what's the best buy in terms of price/performance: 5850 toxic or 6950?Please clarify. Keep it up :)

The 6950 offers a much more robust tessellation engine, so will do better in the more recent generation of DX11 games than a 5870.
There have also been reports of BIOS updates that turn a 6950 into a 6970, but that would be a lucky byproduct; I wouldn't count on that.
The 6950 is roughly equal to a 560 Ti. Note that Nvidia's stereoscopic 3D support for games is much better at this point. AMD relies on third parties with rather spotty game support. However, those work well with 3D Blu-ray.

Thanks for the update, lyod.
I'm planning to go with Sapphire 5950 2GB Toxic Ed. card once it's launched, hope they launch it by April or so because am planning buy i7-2600K and P67 MOBO in that time. Reason is I'm not sure of Nvidia 570's power and aacoustics compared to that 6950 card. Any input in this regard? (first hand experience). Thanks.

If the overclocked ASUS 460 is noisy, why not use Gigabyte's or EVGA's? Do you guys think ALL overclocked 460s are noisy?

I also noticed that most cards were either XFX or Asus. I guess they are some kind of sponsors to this magazine?
loyd

No, it was more like Asus, XFX and eVGA were able to deliver cards for testing before our deadlines. I did try to hit up other vendors, too, but they weren't able to participate.

So in this article you guys said the 768mb gtx 460 beats the 6850... yet in the conclusion you recommend the 6850 over its for twice?
loyd
February 14, 2011 at 12:24pm
The benchmarks show the two cards being pretty close... but the 1GB VRAM on the 6850 will likely mean better performance with AA and AF turned up. Plus, the 6850 is more power efficient and quieter.

This article really clarified a lot of confusion I had in the GPU field, since numbers and specs show one thing, and real world use and benchmarks show another. I've been searching for GPU's in a certain price range and it has been a struggle to decide which one to get, since the specs can get confusing. This article eased my decision substantially. Two thumbs up.

5970 is only super fast for dx10 applications. Even gtx 480s dominate the 5970 in a majority of applications. I own quadfire 5970s as well as tri sli 480s. In 90% of applications and dx11 games the tri sli 480s slaughter the quadfire 5970s. I don't game in dx10 so the 5970s rarely get used. If you look at benchmarks the 580 scores higher than the 5970 in most modern cases.

Just about any article you guys create that contains benchmarks is the bees knees. lol. Especially since unlike a preview or opinion article, you actually have to go through the task of preparing each setup, recording data, then write a story about your findings. Although this being said, I'm going to have to just put this out there that while I enjoy all of them (please don't kill me), Gordon's are usually the ones I read, re-read and re-read some more. Useful stuff. But, I'm going to have to agree with most of the people here and say that my favorite recent article is Loyd's AMD vs Nvidia: 10 Videocards Go Head-to-Head article. My buddies and I always have enlightening arguments on what it is the latest and greatest part on each price level and CPUs and GPUs are always mentioned in the conversation. Aside from the article being clearly spoken, well written and extremely informative, it settled most current GPU debates. Haha. Great aticle from a great magazine. I'm going to have to re subscribe since it runs out next month though. haha

As far as I can tell by my own research, current Nvidia cards including the ones reviewed have the same claimed digital video hardware decoding capabilities. The marketing name from Nvidia is "PureVideo", and "VP3" seems to offer substantially the same codec support as AMD's "UVD3". Is there actually a significant difference in decoding capabilities between these Nvidia and AMD cards?
As to HD video encoding, Nvidia's CUDA seems to be much more widely exploited for GPU processing in general, including use by encoding software.
Of course, for most MaximumPC readers, video decoding and encoding capabilities are fairly minor considerations, though it's important to me.
BTW, I'm not an Nvidia fanboy; I have both types of cards in different systems.

In the 12/1/10 article, "How to Build the Ultimate Digital Photo Studio the recommended GPU was the Evga GeForce GTX 470. In light of the upcoming GPU's would you still recommend this as the best GPU for a computer build oriented toward still and/or movie photography.

It's really all about what Adobe officially supports. For example, while there were hacks to enable GTX 460 cards to accelerate Premiere, Adobe only officially supported the 470 and above. I'd suggest sticking with supported cards to minimize support hassles. Adobe only seems to update the supported cards list on an irregular basis.

Loyd,
I would like to know your thoughts on the new gtx 560 ti and how they stack up to hd 6870. I currently have a gtx 280 and will be upgrading my rig soon, any input you have on a sub $300 card is appreciated.

The 560 Ti is a pretty killer GPU. It's pretty much unbeatable at the $250-$260 price point, and forced AMD to drop the price on the HD 6870.

I like this article because it felt very fair to me. I've seen a lot of reviews for the news series of cards where they declare a manufacturer a winner, not an individual card. This felt very much true to the cards as individual cards and not a fanboy mudslinging contest like a lot of reviews I've seen these days. Well done.
