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.

New Drivers From NVIDIA Change The Landscape

    One is an open, one is not.

    Jesus christ.

    The fact you have to pay extra on top of the card prices to use these features is a no go. You start to lose value, thus negating the effect these "features" have.

    p.s ATI have similar features to nvidia, what they have is nothing new.

    Did you see a charge for ambient occlusion ?
    Here you are "clucky clucky cluck cluck !"
    Red rooster, the LIARS crew.

    One ? I count for or five. I never had to pay extra outside card cost for PhysX, did you ?
    You see, you people will just lie your yappers off.
    Yeah ati has PhysX - it's own. ROFLMAO
    Look, just jump around and cluck and flap the rooster wings and eat some chickseed, you all can believe eachothers LIES. Have a happy lie fest, dude.

    Personally while you bring up good points I'd much, much, MUCH rather have the thorough explanation of CUDA and PHYSX and the relevance thereof, they gave us than power, heat and overclocking numbers you can get at dozens of other reviews. The former is insight, the latter just legwork. Reply

    I really like to soft shadows you get in the corners with the new AO features in nVidia's drivers. Very neat. Reply

    I had a 4850 that I bought at launch. I was very excited when ATI released their Video Convertor app. I spent days trying to make that produce watchable video. Then I realized that every website that tested it had the same result. They released a broken POS and have yet to fix it. I did not appreciate them treating me like that so when I replaced the card I switched out to Nvidia. I have gone back and forth but this time I think I will stick with Nvidia for a while. Reply
  • duploxxx - Thursday, April 02, 2009 - link

    and by buying Nvidia you already knew that you didn't have POS so in the end you have the same result, except for the fact that the 48xx series really had a true performance advantage with that price range so your rebranded replacement just gave you 1) additional cost and 2) really 0 added value, so your grass is a bit to green.....

    "0 added value"? Really? He didn't have a GPU video converter that worked on his ATI card, and now he DOES have a working program with his Nvidia card. Sounds like added value to me. He gets the same performance, pretty much the same price, and working software. Not a bad deal... Reply
  • z3R0C00L - Thursday, April 02, 2009 - link

    The GPU converted that comes with nVIDIA is horrible (better than ATi's though).

    I use Cyberlink PowerDirector 7 Ultra which supports both CUDA and Stream. Worth mentioning that Stream is faster.
  • Spoelie - Thursday, April 02, 2009 - link

    Is the 30$ pricetag of badaboom included in the "pretty much the same price"? If it isn't, then actually there is no added value. You have a converter (value, well only if your goal is to put video's on your ipod and it's worth 30$ to you to do it faster) but you have to pay for it extra. The only thing the nvidia card provides is the ability to accelerate that program, you don't actually get the program. Reply
