After having taken a long hard look at GPUs last fall, it is time, once again, to see what the graphics card vendors have to offer the world. We wanted to get our hands on as many cards as possible in order to put together a roundup of epic proportions.

There is more to buying a graphics card than an IHV's chip, and the tender loving care that the OEMs give their cards is where much of the end user value comes from these days. In this review, we will take a look at each card and what it has under the hood, along with its GPU. Beyond the gaming experience, we will be looking at fan noise and heat dissipation as well as which memory modules the vendor decided to use. Some of the cards are even pre-overclocked for our gaming pleasure.

We will see everything from two-fan cooling solutions to LCD temperature and fan speed readouts. After looking at what each card has to offer above and beyond the performance, we will put them all to the test. Obviously, if the cards all run at reference speeds, they will all perform similarly to earlier tests that we have already completed. We've got something more special in mind.

We are going to overclock each card to its highest stable core and memory speed, and then run a few select benchmarks to cover the most recent few DirectX releases as well as OpenGL. All told, 23 cards were benchmarked, so we didn't have the ability to run a whole suite of tests on each one.

Keep in mind, when looking at overclocking, that every single card is different. We are only hoping to get an idea of what a particular vendor's cards can do. Heat sink and fan selection are very important to overclocking, as is RAM cooling and board layout. Though these issues impact overclocking a great deal, they, alone, do not dictate success or failure at any given clock speed. Each GPU, RAM module, capacitor, etc. has different limitations, which can only be determined experimentally.

Beyond understanding what the vendors are doing, we will be able to glean a little more information about the IHV's GPUs. Hopefully, our tests will tell us what kind of speed increases we can expect from each core, and what impact core and memory clock speed have on performance. But that's enough talk. Take a look at the cards in our lineup.

UPDATE: As the performance tests in this article place a heavy weight on overclockability, it is important to note that the Radeon 9800 (R350/R360) based cards are fabbed on a 150nm process and will have a little more trouble overclocking than the 130nm parts that make up the rest of the cards we tested. Also, NVIDIA GPUs underclock themselves when running in 2D mode, so their idle temperatures will be lower on average than the ATI based solutions. We appologize for having omitted this information from initial publication.

    They should have included the 9700PRO in the benchmarks IMO Reply

    Great article. Almost like old-school AT, except better in many ways. Mr. Wilson, your thoroughness is appreciated and made for a great read. Reply

    if if you look back you will note that i did ask if you knew why the discrepancy existed. if i didn't know myself, i would have simply asked why and not directed my question at your knowledge of the situation. while i cannot argue against your comment that the information is available elsewhere, i doubt that you can argue that the omission of it in your review undoubtably serve to mislead the portion of the community who is not aware that you are comparing underclocked and undervolted cards to overclocked ones. as for linking to the original technology overviews or creating a page or two on the feature sets, that doesn't seem like a good idea when a single sentence explaining the situation would be much more effective in avoiding any possible confusion.

    Why didn't you ask that question in the first place snowman ;-)

    The info was left out because we didn't feek it was relevant (the operation of reference nvidia and ati cards has been well documented on this site and on others).

    If you would prefer, in future roundups we can point to our articles introducing which ever GPUs we are including. If that's not enough, we can have a page or two dedicated to going over all the features the various reference cards have.

    ya actually i knew that nvidia underclocks and undervolts their cards in 2d mode, i was just curious id Derek did. it struck me as rather odd that he would go though the trouble of presenting core temps while leaveing out such a vital factor in understanding the results. Reply

    Snowman (and Derek), remember that the FX5900 cards (all of them?) have 2D and 3D speeds. This has been the case since the FX 5800. Basically, they usually run at 300 MHz core and memory (DDR = 600 MHz) and when a 3D application loads, they bump up to the higher speed. It was done initially so that they could run the "leaf blower" 5800 fan at lower RPMs when you didn't need the extra power.

    This is okay, I guess, but it might be an issue if you were to run games for 48 hours straight or something. Technically, I think the one speed option by ATI is better for peace of mind - if it can always run at that speed, you don't need to worry as much about instability after prolonged gaming sessions.

    From the benchmarks here, I have to agree that the FX5900 SE cards seem to be the best choice right now. Relatively close to the 5900 ultra and 5950 ultra, at almost half the cost! I think more of these cards should have been included instead of the 5700 Ultras. Who would spend $175+ on a 5700 Ultra when the 5900 SE/XT/regular costs about the same ($185+) and beats it pretty soundly in every benchmark? There are also some 5900 cards that list 850 MHz as the RAM speed (the eVGA lists 700) - they might cost $30 to $50 more, but maybe they use the 2.2ns or 2.0ns RAM? They could potentiall be as fast as the Ultra cards and cost $100 less!

    also the vcore of the nvidia chips is at 1.2v in 2d mode and 1.6v in 3d mode. Reply

    Noise and heat are a huge concern for me, so I'll probably put the 9600xt Ultimate in my sff, BUT when doom3 and some of the heavier games drop are the 4 pipes opposed to 8 gonna hurt me enough to buy a new card? Reply

    The EVGA 5900se is missing from the Temp graphs. Reply

    If you go back and look at the older scores for Unreal Tournament and Halo you'll see that (with the exception of 4xAA/8xAF in UT) ATI's high end cards haven't really done better in those two games:

    UT: http://anandtech.com/video/showdoc.html?i=1896&...
    Halo: http://anandtech.com/video/showdoc.html?i=1896&...

    If we had turned on AA/AF we would have seen ATI do better in UT.

    Many people crucified the NVIDIA cards with Tomb Raider, Aquamark3, ShaderMark and Tron benchmarks. The problem is that there are popular games out there that NVIDIA cards perform better in, and that info got lost in the shuffle.

    When it comes down to it, ATI's 9800XT is the best card out there if you aren't going to overclock. The 9600XT and the 5700U are just about the same in terms of goodness, and if you want a card in that price range, I'd recommend a cheap 5900 based card instead.

    TheSnowman:
    There are some issues with that. Since ATI and NVIDIA don't measure temp the same way, and we haven't been able to come up with a really solid way of standardizing temperature measurements between the two, we have to rely on what the driver says. We are looking for better methods of measuring the temperature of each card.

    That being said, I can venture a guess on why nvidia cards idle lower. Powerstrip offers me settings for 2D and 3D operation with NVIDIA cards, but I only get one setting to play with from ATI. The standard 2D clock speed for NVIDIA GPUs is anywhere from 1 to 2 hundred MHz lower than their 3D clock speed (generally 2D for the 5950 is 300MHz core). The memory clocks were locked between 2D and 3D operation and couldn't be set seperately.
