ATI Radeon HD 4890 vs. NVIDIA GeForce GTX 275

I'm not really sure why we have NDAs on these products anymore. Before we even got our Radeon HD 4890, before we were even briefed on it, NVIDIA contacted us and told us that if we were working on a review to wait. NVIDIA wanted to send us something special.
Then in the middle of our Radeon HD 4890 briefing what do we see but a reference to a GeForce GTX 275 in the slides. We hadn't even laid hands on the 275, but AMD knew what it was and where it was going to be priced.
If you asked NVIDIA what the Radeon HD 4890 was, you'd probably hear something like "an overclocked 4870". If you asked AMD what the GeForce GTX 275 was, you'd probably get "half of a GTX 295".
The truth of the matter is that neither one of these cards is particularly new, they are both a balance of processors, memory, and clock speeds at a new price point.
As the prices on the cards that already offered a very good value fell, higher end and dual GPU cards remained priced significantly higher. This created a gap in pricing between about $190 and $300. AMD and NVIDIA saw this as an opportunity to release cards that fell within this spectrum, and they are battling intensely over price. Both companies withheld final pricing information until the very last minute. In fact, when I started writing this intro (Wednesday morning) I still had no idea what the prices for these parts would actually be.
Now we know that both the Radeon HD 4890 and the GeForce GTX 275 will be priced at $250. This has historically been a pricing sweet spot, offering a very good balance of performance and cost before we start to see hugely diminishing returns on our investments. What we hope for here is a significant performance bump from the GTX 260 core 216 and Radeon HD 4870 1GB class of performance. We'll wait till we get to the benchmarks to reveal if that's what we actually get and whether we should just stick with what's good enough.
At a high level, here's what we're looking at:

We suspect that this will be quite an interesting battle and we might have some surprises on our hands. NVIDIA has been talking about their new drivers which will be released to the public early Thursday morning. These new drivers offer some performance improvements across the board as well as some cool new features. Because it's been a while since we talked about it, we will also explore PhysX and CUDA in a bit more depth than we usually do in GPU reviews.
We do want to bring up availability. This will be a hard launch for AMD but not for NVIDIA (though some European retailers should have the GTX 275 on sale this week). As for AMD, we've seen plenty of retail samples from AMD partners and we expect good availability starting today. If this ends up not being the case, we will certainly update the article to reflect that later. NVIDIA won't have availability until the middle of the month (we are hearing April 14th).
NVIDIA hasn't been hitting their launches as hard lately, and we've gotten on them about that in past reviews. This time, we're not going to be as hard on them for it. The fact of the matter is that they've got a competitive part coming out in a time frame that is very near the launch of an AMD part at the same price point. We are very interested in not getting back to the "old days" where we had paper launched parts that only ended up being seen in the pages of hardware review sites, but we certainly understand the need for companies to get their side of the story out there when launches are sufficiently close to one another. And we're certainly not going to fault anyone for that. Not being available for purchase is it's own problem.
From the summer of 2008 to today we've seen one of most heated and exciting battles in the history of the GPU. NVIDIA and AMD have been pushing back and forth with differing features, good baseline performance with strengths in different areas, and incredible pricing battles in the most popular market segments. While AMD and NVIDIA fight with all their strength to win customers, the real beneficiary has consistently been the end user. And we certainly feel this launch is no exception. If you've got $250 to spend on graphics and were wondering whether you should save up for the GTX 285 or save money and grab a sub-$200 part, your worries are over. There is now a card for you. And it is good.

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....
7Enigma - Thursday, April 2, 2009 - link
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...
