Mid Range Graphics Card CPU scaling

For mid-range cards we've got three from ATI and one from NVIDIA; as we've discovered in previous Half Life 2 articles, NVIDIA's last-generation mid-range cards are only reasonable performers in DirectX 8 mode, and we are conducting a fully DX9 comparison here so that excludes all of them. From ATI we've got the Radeon 9700 Pro, Radeon 9800 Pro and Radeon X700 Pro. We've also included the NVIDIA GeForce 6600GT, which as you will remember from our previous articles, performs very similarly to the GeForce 6800 non-ultra under Half Life 2.

Our mid-range tests were conducted at 1280 x 1024, the target resolution for most mid-range cards.

If you've got any of ATI's mid-range GPUs, you're stuck with severely diminishing returns after about 1.4 - 1.6GHz on the Athlon 64 (< 2800+ range). The GeForce 6600GT is far less GPU bound at 1280 x 1024 (and even at 1024 x 768 although not depicted here), and thus scales relatively well.

    by the way, you can't mod a 9500Pro to a 9700Pro, the 9500Pro circuit-board only has a 128-bit memory-bus and there's no way you can change it to 256-bit. Reply

    #55- the cut-off point where you can't really tell the difference of a higher framerate, is when the framerate exceeds the monitor refresh rate.

    If your monitor is updating the display 85 times per second (a common setting for cheaper CRT displays), then a *minimum* framerate of higher than 85fps makes no difference. With flat-panels, refresh-rates of 60-75hz are more common so you don't even need to maintain 85fps. A faster graphics-card is still worthwhile though as it allows you to crank up AA and Aniso settings (8x anti-aliasing is lovely).

    Coming from the recent dark age of a P4 1.7/9500Pro(@9700Pro) combi, this is great article to decide on my new machine. Although HL2 is playing quite nicely, I am lucky to have a one-off opportunity to buy myself a FX-55/X800XT combi.
    Never having experienced even any fps close to what's on these charts, something in the back of my mind keeps saying that a 10-20 fps more when you are already over 100 fps, will make no difference to the experience except a bigger hole in my wallet. Can anyone tell me where the 'cut-off' point is where even the most discerning of gamers cannot see/feel the difference? Knowing that dual core is coming up (even though games for them still need to be made), would buying a 3500+ be smarter or should I go for the FX-55 simply because I can (only this once)? Thx Anand for the article.

    Those graphs look nice, but they don't really mean much. Based on similar graphs and results I just bought a a64-4000+ and MSI Neo2 Platinum to replace my P4-3.2GHz and Asus P4c-800E.

    With the same ATI X800XT Platinum, memory, and hard drives, I can't see any difference between then, in fact, the P4 seemed to play smoother.

    Do I have any proof, no, other than playing half-life 2 on my p4 was more enjoyable.

    Can anyone offer some insight into why the extreme edition northwoods did as poorly as they did? The 3.2GHz EE could barely keep up with the 3.0GHz Prescott; so, it's more than the raw clock speed of the high end Prescotts.

    Could it be related to running the Northwood on a platform really intended for Prescotts?

    Awesome article. It was exactly what I've been looking for. My 2600+ is not cutting it with my 6600GT AGP and I was thinking it was the CPU that was limiting preformance. Reply

    Firing Squad did a review on the Athlon XP performance with HL2 a while ago:


    The 3200+ XP got about 95fps in the Canals_09 demo at 1280x1024 with an X800 XT PE. Not sure how well it compares to the Canals_08 that Anandtech uses, but I doubt the difference would be that great.

    I'm very dissapointed with this article. I have been eagerly awaiting it for ages, expecting to see how Half-Life 2 scales down to lower speed processors; I've long maintained that low end processors like an AthlonXP 1900+, run the game quite poorly.

    The big deal with HL2 is that it was supposed to run on much older computers. But nobody seems to have benchmarked it on anything but pretty new hardware. I expected that a CPU scaling article would cover that, in fact I thought that was the entire point.

    i'd be curious to see normal 6600, as well as maybe some lower-end ati card in the comparison :)
    ok ok, i know this isn't a GPU shootout, but still...
