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.

Well thanks for stomping the red rooster into the ground, definitively, after proving, once again, that what an idiot blabbering pussbag red spews about without a clue should not be swallowed with lust like a loose girl.I mean it's about time the reds just shut their stupid traps - 6 months of bs and lies will piss any decent human being off. Heck, it pissed off NVidia, and they're paid to not get angry. lol

arggh, lots of typoos."Mirrors Edge's PhysX in other hand does show indeed add a lot of graphical feel. " should have been : Mirrors Edge's physx in other hand, does indeed show a lot of new details.

Firstly, I agree with the articles basic premise that lack of convincing titles for PhysX/CUDA means this is not a weighted factor for most people.I am not most people, however, and I enjoy running NVIDIA's PhysX and CUDA SDK samples and learning how they work, so I would sacrifice some performance/quality to have access to these features (even spend a little more for them).
The main point I would like to make, however, is that I like the fact that NVIDIA is out there pushing these capabilities. Yes, until we have cross-platform OpenCL, physics and GPGPU apps will not be ubiquitous; but NVIDIA is working with developers to push these capabilities (and 3D Stereo with 3D VISION) and this is pulling the broader market to head in this direction. I think that vision/leadership is a great thing and therefore I buy NVIDIA GPUs.
I realize that ATI was pushing physics with Havok and GPGPU programming early (I think before NVIDIA), but NVIDIA has done a better job of executing on these technologies (you don't get credit for thinking about it, you get credit for doing it).
The reality is that games will be way cooler when the you extrapolate from Mirror's Edge to what will be around down the road. Without companies like NVIDIA out there making solid progress on executing on delivering these capabilities, we will never get there. That has value to me I am willing to pay a little for. Having said that, performance has to be reasonable close for this to be true.

Games will be better when we get better effects, and PhysX has some potential to do that. However, the past is a clear indication that developers aren't going to fully support PhysX until it works on every mainstream card out there. Pretty much it means NVIDIA pays people to add PhysX support (either in hardware or other ways), and OpenCL is what will really create an installed user base for that sort of functionality.If you're a dev, what would you rather do: work on separate code paths for CUDA and PhysX and forget about all other GPUs, or wait for OpenCL and support all GPUs with one code path? Look at the number of "DX10.1" titles for a good indication.

Agreed.NVidia has certainly received credit for getting accelerated physics moving, but its momentum stops when they couple it to CUDA when offering it to discrete graphics cards outside of the GeForce family.

Still no 3D Mark scores, STILL no low-med resolutions.Thanks for including the HD4850, where's the GTS250??? Or do you guys still not have one? Well, you could always use a 9800GTX+ instead, and actually label it correctly this time. Anyway, thanks for the review and all the info on CUDA and PhysX; pretty much just confirmed what I already knew; none of it matters until it's cross-platform.

3DMark can be found in just about every other review. I personally don't care, but realize people compete on the Orb, and since it's just a simple benchmark to run it probably could be included without much work. The only problem I see (and agree with) is the highly optimized nature both Nvidia and ATI put on the PCVantage/3DMark benchmarks. They don't really tell you much about anything IMO. I'd argue they not only don't tell you about future games (since to my knowledge no (one?) games have ever used an engine from the benchmarks), nor do they tell you much between cards from different brands since they look for every opportunity to tweak them for the highest score, regardless of whether it has any effect in realworld performance.What low-med resolution are you asking for? 1280X1024 is the only one I'd like to see (as that's what I and probably 25-50% of all gamers are still using), but I can see why in most cases they don't test it (you have to go to low end cards to have an issue with playable framerates on anything 4850 and above at that resolution). Xbitlabs' review did include 1280X1024, but as you'll see, unless you are playing Crysis:Warhead, and to a lesser extent Farcry2 with max graphics settings and high levels of AA you are normally in the high double to triple digits in terms of framerate. Any resolution lower than that, you've got to be on integrated video to care about!
