Round 2: Performance

In an attempt to demonstrate the capabilities of these cards, we have run these game tests at their highest quality levels. This means that the cards will be pushed harder with more detail. Most importantly, the entire card will be well stressed. This will give us an idea of how these lower memory cards can deliver on the promise of an experience comparable to all other cards of the current generation.

In the end, it will be up to the end user whether to enable the highest quality settings and run at lower resolutions, or to turn off a few of the bells and whistles and pump up the number of pixels packed on to the screen a bit. The tradeoff really comes down to preference. Even for the AT staff, the resolution vs. settings argument is addressed on a game by game basis.

We will be taking a look at 4 flavors of cards today. We have 3 different TurboCache models and 1 HyperMemory board. Our HyperMemory board is the 32 MB model while we have 16, 32, and 64 MB TurboCache cards. With the exception of the 16MB TC board, these boards have a 64-bit memory interface. The 16MB card's memory bus is only 32-bits wide.

Aside from memory size and bus width, speed is an important factor with these boards. Vendors are looking at cheap for these boards, so we won't be seeing <2ns GDDR3 here. Instead, memory speeds are at most 700 MHz (the speed of the 16 and 32 MB TC cards). The HyperMemory card runs with RAM clocked at about 665MHz while the 64MB TC card runs at a rather slow 550 MHz. This will serve to change the performance landscape of the TurboCache cards, as having faster memory will really help the boards with less memory. The advantage of the 64MB card then becomes the ability to run applications that require 256MB of graphics memory. This will not likely be as useful as having higher performance under a 128MB graphics memory setup.

It is also possible to create 32bit wide 32MB cards, but these will experience a definite performance hit. It will be important for the consumer to pay attention to the amount of graphics memory that their solution supports, the amount of RAM that it has locally, and the bit width of the local memory interface. Needless to say, we will probably be less than satisfied with the way that these cards are marketed. Of course, giving vendors a wide range of choices based on their needs will hopefully help to keep competition up and prices down in the market.

The test setup that we used was designed to put the most emphasis on the graphics cards capabilities. As such, we should keep in mind that we are very graphics card limited here and should see very similar performance on quite a range of CPUs (until we start becoming CPU limited in games). These cards will be most sensitive to RAM used in a system, and it is our recommendation that if these cards are intended to be used by the casual gamer, memory choice should be given careful consideration. Here's what the cards ran in:

Microsoft Windows XP SP2
ASUS A8N-SLI Deluxe
AMD Athlon FX-53
1GB OCZ PC3200 @ 2:2:2:9
Seagate 7200.7 HD
OCZ Powerstream 600W PS

The 32MB 304/665 (core/mem) HyperMemory card that we have is direct from ATI, while the 32MB and 64MB 350/700 (core/mem) TurboCache cards are from PNY. The 16MB TurboCache part was from NVIDIA and is clocked the same as the PNY parts.

This is quite a lot to keep in mind when looking at our performance tests. Unfortunately, it's not a simple matter to understand what we are seeing at first glance. But, that being said, what follows paints quite a good picture of the budget market as it stands.

    Hello Derek, are you planning to test the AGP 6200 version which uses the NV44A core - it's virtually the same core as the PCI-E Turbo-Cache cards, except it is a native AGP solution. They are all 64-bit as far as NVidia have told me and although all board makers only provide passive cooling, that's all it needs. I've only seen one brief review on another website so far (of the Inno3D one) that didn't really have enough information. As reviews on Anandtech are very thorough, it would be good to test and compare this card. The core is clocked at 350MHz like the Turbo-cache cards and the card has 128mb of 500MHz effective memory.

    Typo?

    " ...the bear minimum in graphics cards supports DX9 level graphics...
    "

    Shouldn't bear be bare?

    The x300 HM results wouldn't be so disappointing if ATI had not been saying that HM cards would be faster than TC cards.

    Derek: 128MB HM doesn't make much of a difference. I had an XPRESS 200M laptop with 128MB dedicated memory plus HyperMemory and performance was horrible, much much slower than a x300 SE. I wouldn't be surprised if turning off HM made the card faster.

    #23 Jarred- "Despite the fact that the system was high-end, the performance of the cards is the limiting factor. A 3.0 GHz or 3000+ CPU with the same amount of RAM would likely post similar scores. However, 512MB of RAM would have something of an impact on performance. Anyway, $100 gets you 1GB of RAM these days, so we're more or less through with testing anything with 512MB of RAM or less."

    Whilst I agree that 1GB and it is not unreasonable for even budget systems to have that amount, $100 certainly won't buy you 1GB of OCZ PC3200 with 2-2-2 timings. Given that the performance of these cards is very dependent on system memory and a budget system is likely to use budget memory, it is important to have benchmarks done with 2.5-3-3 timings or even 3-3-3.

    I support AT's use of a very fast CPU etc in all their usual graphics-cards reviews, and a very fast GPU for all their CPU reviews, so that performance is dependent on the component being tested rather than the rest of the system. However with the TurboCache and HyperMemory cards, the system memory effectively becomes an important part of the card, so it is important to test with the sort of budget memory these cards would be used with.

    By using premium memory, AT has probably reduced the importance of the quantity of onboard memory and skewed the relative results of the tested cards. The 64MB TC may have performed significantly better in comparison with the others, had the test system been outfitted with 1GB of budget memory at 3-3-3 timings.

    #28, you can get decent integrated graphics with the ATI XPRESS 200 chipset - however the only motherboard at NewEgg is $102, which is a bit high. I once saw them for around $80.

    "...perhaps upcoming integrated graphics solutions from ATI and NVIDIA will be as compelling as these parts show value products can be."

    I have a need for cheap but functional graphical PCs for smaller children, so I'm still waiting for a replacement for the NVIDIA nForce2 IGP. What's the holdup?

    Our comparison tests will continue to be done on higher end hardware. Our environments are designed to test the performance of graphics hardware not to determine the actual performance an end user can expect.

    We run these games on a fresh install of Windows XP SP2. Audio hardware is not installed and the service is disabled in Windows. Nothing that isn't necessary to get the graphics to the screen is not enabled.

    Most people have lots of background programs, services, and audio running. With the way Intel and AMD are approaching dual core, multitasking is perched to become even more pervasive. This will enevitably widen the gap between our tests and real world performance when we are looking at graphics cards. Our CPU performance tests will continue to grow and include more and more multitasking as we are able to come up with the tests.

    Of course, #25 has a very valid point -- it may well be worth it to run one test in a price targeted system running a more "typical use" environment for reference purposes. Budget systems cluttered with loads of apps running in the background are no place to build a hardware comparison, but that doesn't mean they are entirely unuseful.

    It would be useful, however, to include benchmarks with all budget hardware - to see if you really can get acceptable (30fps+) gaming performance with these cards in realistic settings.

    Thanks Derek.

    Seems crazy that there's no DVI since CRT's are
    going away fast. Even my old budget 9200SE card
    had DVI.

    Just wondering..I would think with 17inch LCD's
    around $175 and 19inch around $300 (with DVI)
    that this is the future.
    What do you all think?
