ATI Radeon HD 4890 vs. NVIDIA GeForce GTX 275

Final Words
NVIDIA is competitive at this new price point of $250 depending on what resolution you look at. We also see some improvement from NVIDIA's new 185 series driver and get a new feature to play with in the form of Ambient Occlusion. We did look at PhysX and CUDA again, and, while we may be interested in what is made possible by them, there is still a stark lack of compelling content that takes advantage of these technologies. We can't recommend prioritizing PhysX and CUDA over performance, and performance is where a GPU needs to compete. Luckily for NVIDIA, the GTX 275 does.
The fact that its worst-case performance is still better than the GTX 260 core 216 and in the best case, it can hit that of the GTX 280 was a plus for the GTX 275. It often posted performance more in line with its bigger brothers than a $50+ cheaper part. This is pretty sweet for a $250 card, especially as many games these days rely very heavily on shader performance. The GeForce GTX 275 is a good fit for this price point, and is a good option. But then there's the Radeon HD 4890.
The 4890, basically a tweaked and overclocked 4870, does improve performance over the 4870 1GB and puts up good competition for the GTX 275. On a pure performance level the 4890 and GTX 275 trade blows at different resolutions. The 4890 tends to look better at lower resolutions while the GTX 275 is more competitive at high resolutions. At 1680 x 1050 and 1920 x 1200 the 4890 is nearly undefeated. At 2560 x 1600, it seems to be pretty much a wash between the two cards.
At the same time, there are other questions, like that of availability. With these parts performing so similarly, and price being pretty well equal, the fact that AMD parts can be bought starting today and we have to wait for the NVIDIA parts is an advantage for AMD. However, we have to factor in the fact that AMD driver support doesn't have the best track record as of late for new game titles. Add in the fact that NVIDIA's developer relations seem more effective than AMD's could mean more titles that run better on NVIDIA hardware in the future. So what to go with? Really it depends on what resolutions you're targeting and what the prices end up being. If you've got a 30" display then either card will work, it's just up to your preference and the items we talked about earlier. If you've got a 24" or smaller display (1920x1200 or below), then the Radeon HD 4890 is the card for you.
AMD tells us that most retailers will feature mail in rebates of $20, a program which was apparently underwritten by AMD. Could AMD have worried they weren't coming in at high enough performance late in the game and decided to try and throw an extra incentive in there? Either way, not everyone likes a mail in rebate. I much prefer the instant variety and mail-in-rebate offers do not make decisions for me. We still compare products based on their MSRP (which is likely the price they'll be back at once the rebate goes away). This is true for both AMD and NVIDIA parts.
There will also be overclocked variants of the GTX 275 to compete with the overclocked variants from AMD. The overclock on the AMD hardware is fairly modest, but does make a difference and the same holds true for the GTX 275 products in early testing. We'll have to take a look at how such parts compare in the future along with SLI and CrossFire. In the meantime, we have another interesting battle at the $250 price point.

Can anyone tell me about the testing metod average or maximum fps? thanks.Jamahl - Thursday, April 2, 2009 - link
some sites have the gtx275 clearly winning at all games, all resolutions.helldrell666 - Thursday, April 2, 2009 - link
You can't trust every site you check.especially since most of those sites don't post their funders names on their main page.You must've heard of Hardocp's Kyle who was fired by nvidia because he mentioned that the gtx250 is a renamed 9800gtx.7Enigma - Thursday, April 2, 2009 - link
I think this is due to Nvidia shooting themselves in the leg with the 185 drivers. With the performance penalty at the normal resolutions, anyone testing with the 185's is going to get lower results than someone testing with the previous drivers. And I'm sure you could find 10 games that all perform better on ATI/NVIDIA. That's the problem with game selection and the only real answer is what types of games you play and what engines you think will be used heavily for the next 2 years.SiliconDoc - Monday, April 6, 2009 - link
Well the REAL ANSWER is - if you play at 2650, or even if you don't, and have been a red raging babbling lying idiot red rooster for 6 months plus pretending along with Derek that 2650x is the only thing that matters, now you have a driver for NVidia that whips the ati top dog core...If you're ready to reverse 6 months of red ranting and raving for 2560X ati wins it all, just keep the prior NV driver, so the red roosters screaming they now win because they suddenly are stuck at the LOWER REZ tier to claim a win, can be blasted to pieces anyway- at that resolution.
So - NVidia now has a driver choice - the new for the high rez crown they took from the red fanboy ragers, and the prior driver which SPANKS THE RED CARD AGAIN at the lower rez.
Make sure to collude with all the raging red roosters to keep that as hush hush as possible.
1. spank the 790 at lower rezz with the older Nvidia driver
2. spank the 790 at the highest rez with the new driver

Can someone ban this freaking idiot. The last few posts of his have been nothing but moronic, senseless rants. Jesus Christ, buy a gun and shoot yourself already.SiliconDoc - Tuesday, April 7, 2009 - link
Ahh, you don't like the points, so now you want death. Perhaps you should be banned, mr death wisher.If you don't like the DOZENS of valid points I made, TOO BAD - because you have no response - now you sound like krz1000 and his endless list of names, the looney red rooster that screeches the same thing you just did, then posts a link to youtube with a freaky slaughter video.
If I wasn't here, the endless LIES would go unopposed, now GO BACK and respond to my points LIKE MAN, if you have anything, which no doubt, you do not.

According to xbitlabs, the 4890 beats the gtx285 at 1920x1200 resolution with 4x aa in Cod5, Crysis Warhead, Stalker CS, Fallout 3 and loses in Far Cry2.Here, the 4890 matches in Far Cry 2 and cod5 with some slightly lower fps than the gtx285 in Crysis warhead.Strange....

That is crazy. There is no way variations should be that huge between the 2 tests, regardless of the area they chose to test in the game. Anandtech has it as essentially a wash, while Xbit has the 4890 20% faster!?! (COD:WaW)7Enigma - Thursday, April 2, 2009 - link
Just looked closer at the Xbitlabs review. The card they used was an OC variant that had 900MHz core instead of the stock 850MHz. In certain games that are not super graphically intensive I'm willing to bet at 1920X1200 they may still be core starved and not memory starved so a 50MHz increase may explain the discrepancy.I've got to admit you need to take the Xbitlabs article with a grain of salt if they are using the OC variant as the base 4890 in all of their charts....that's pretty shady...
