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.

Don't worry, it is mentioned in the article their overclocking didn't have good results, so they're keying up a big fat red party for you soon.They wouldn't dare waste the opportunity to crow and strut around.
This was about announcing the red card, slamming nvidia for late to market, and denouncing cuda and physx, and making an embarrassingly numberous amount of "corrections" to the article, including declaring the 2560 win, not a win anymore, since the red card didn't do it.
That's ok, be ready for the change back to 2560 is THE BESt and wins, when the overclock review comes out.
:)
Don't worry be happy.

SD, you seriously have a mental problem right?I noticed that you keep bashing, being sarcastically insultive (betwen other things.) to anyone who supports ati.

No, not true at all, there are quite a few posts where the person declaring their ATI fealty doesn't lie their buttinski off - and those posts I don't counter.Sorry, you must be a raging goofball too who can't spot liars.
It's called LOGIC, that's what you use against the lairs - you know, scientific accuracy.
Better luck next time - If you call me wrong I'll post a half dozen red rooster rooters in this thread that don't lie in what they say and you'll see I didn't respond.
Now, you can apologize any time, and I'll give you another chance, since you were wrong this time.

I just finished a mid-range C2D build, and decided to go with the HD 4870 512MB version for $164.99 (ASUS, no sale at NE, but back up to $190 now). This was my first ATI card and it was a no-brainer. While the 4890 is a better card, to me, it is not worth the nearly $100 more, especially considering I'm gaming at either 1920x1200 on a 40" LCD TV or a 22" LCD monitor at 1680x1050.Nvidia has lost me after 12 years as a fanboy for the time being, I suppose. What I will do here when I have more time is determine if buying another 4870 512MB for CrossFire will be the better bang for my resolutions or eventually moving up to the 4890 when the price drops this summer and then sell the 4870.
Thanks for the GREAT review AT, and now I have my homework cut out for me for comparisons with your earlier GPU reviews.

Good job with tidying up the conclusion Anand.Russ2650 - Thursday, April 2, 2009 - link
I've read that the 4890 has 959M transistors, 3M more than the 4870.Gary Key - Thursday, April 2, 2009 - link
That is correct and is discussed on page 3. The increase in die size is due to power delivery improvements to handle the increased clock speeds.Warren21 - Thursday, April 2, 2009 - link
Maybe the tables should be updated to reflect this?Gary Key - Thursday, April 2, 2009 - link
They are... :)helpmespock - Thursday, April 2, 2009 - link
I've been sitting on my 8800GT for a while now and was thinking about going to a 4870 1GB model, but now I may hold off and see what prices do.If the 4890/275 force the 4870 down in price then great I'll go with that, but on the other hand if prices slip from the new parts off of the $250 mark then I'll be tempted by that instead.
Either way I think I'm waiting to see how the market shakes out and in the end I, the consumer, will win.
