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.

Yes, exactly why added value of CUDA, PhysX, badaboom, vReveal, the game profiles ready in nv panel, the forced SLI, the ambient occlusion games and their MODS ( se back a page or two in comments) - all MATTER to a lot gamers.Let's not forget card size for htpc'ers - heat, dissipation, H.264 etc.
Just the frames matter here just for ati - formerly at 2560x when ati had that crown, now of course, just for lower resolutions - the most important suddenly to the same reviewers, when ati is stuck down there.
Yeah, PATHETIC describes the dismissal of added values.

I have a CUDA-supporting GPU (8800GTS) and I have rarely used it. Other than to run the CUDA version of folding at home (there is also an Ati Stream version) or to look at the preitty effects in a few games. I don't really think these effects are particularly worthwhile and unless the industry comes together and supports a standard like OpenCL I don't see GPU-based processing becoming important to most uses.SiliconDoc - Monday, April 6, 2009 - link
Here's a clue as to why you're already WRONG.Most "gpu users" use NVidia. DUH.
So while you're whistling in the dark, it's already past that time when your line of crap has any basis in reality.
It takes a gigantic red fanboy brain fart to state otherwise.
Oh well, since when did facts matter when the red plague is rampant?

You can get an Nvidia GPU that runs CUDA and Badaboom for $50; the 9600GT. End of page 13.Hrel - Thursday, April 2, 2009 - link

Just need to some stable OC vs OC results!SiliconDoc - Monday, April 6, 2009 - link
anand doesn't do the overclocked part comparison of the videocard wars - BUT DON 'T worry - a red rooster exception with charts and babbling is no doubt coming down the pike.Keep begging, then they can "respond to customer demands". lol
Oh man, this is going to be fun.
I suggest they start with the gainward gtx260 overclock goes like hell, that whips every single 4870 1g XXX ever made. Sound good ?

What I'm really curious about because neither of the cards is what I'm interested in buying, but I like to follow both companies business strategies:Does nvidia really lose money or is looking at a fat zero on the bottom line with this card?
SiliconDoc - Monday, April 6, 2009 - link
Uhh ati is losing a billion a year.If you want card specifics, that's probably difficult to calculate - and loss leaders are nothing new in business - in fact that's what successful businesses use as a sales tool. Seems ATI has taken it a bit too far and made every card they sell a loss leader, hence their billions in the hole.
Now as far as the NVidia card in question, even if Obama takes over the mean greedy green machine - he and his cabal "won't release the information because it's just not fair and may cause those not really needing help at the money window to be expsoed".
So no, you won't be finding out.
The problem is anyway, if a certain card is a loss leader, they calculate how much other business it brings in, and that makes it a WINNER - and that's the idea.

The physx/cuda section was interesting, although it sounded a bit... whiny.I would LOVE it if someone would write an article about all the PR and marketing shenanigans that go on with reviewers behind the scenes. It'll never happen because it would kill any relationship the author has with the companies, but I bet it would be an eye opening read.
