x800GT, x800 (12p) questions.

[Remedy]

I've been contemplating an upgrade for a client and have been wondering about pipe performance differential.


I understand the x800 standard and pro has 12 pipes. But, the x800GT has 8 pipes and higher clock than the 12 piper. Scaling resolutions above 1024,768 is where the additional pipes start to make a difference.

Here, the x800 is $149 and, the x800GT is $161.

Reading, Legion Hardware's x800pro vs. GT, 850 and 800XL. I don't understand, if the GT only has 8 pipes and supposively detrimental to performance, then why are the benchmarks differing very little to the x800pro? Core clock frequency?

Does anyone else have this or looking to get it want to shed some light on what kind of system you have and your opinion on the GT?

i have that powercolor X800 and it's sweet so far. i've overclocked it to 410/430 right now, but i know it'll go higher; just haven't tried yet.

12pipes > 8pipes

get the X800 anyday over the GT. the remaining 12 pipes will definetely play a factor in eye-candy modes.

What kind of performance gain did you receive from your overclock? Greater continuity @ higher resolution or higher AA and AF settings without dropping frames?

I have an x800, and I oc'd mine to 440/950. My 3dmark05 went up from ~4100 to ~4800, and I'm getting like 10-20 more fps in games. It's a sweet card, especially now with all the rebates they have going on.

hey Remedy, just tried maxing out on some games. used FRAPS.

3000+venice@stock
9npa+ultra
512mb DDR400
X800 410/430

Doom3 @ 1280x960 High Quality : i got 40-60 fps

Half Life 2 @ 1280x960 Med Quality, 2xAA : 60-110 fps

BF2 @ 1024x768 w/everything cranked: chuggy chuggy. i think i need more RAM, cuz if i went straight frames were good, but anytime i turned around it just chugged like crazy.

hope that helps some.

Thanks,

in that review, they used 1600x1200 a resolution that helps the x800gt

at lower resolution, the other cards will open up more of a lead on it

the 800xt isn't a great over clocker, but it's got a great price on it and it's pretty powerful.

Do you mean, 800 "XL" instead of XT? Because that article only showed 800XL,800GT,850pro and vanilla x800.

The results in this test are surprising to me. Conventional wisdom says that as you get to high resolutions and turn on AA/AF, the higher pipeline card (X800) should pull away from the lower pipeline, higher clocked card (X800GT). However, the GT seems to remain neck-and-neck and even beats the X800 in many tests. So that makes it a tough decision between these two, but I don't think you would go wrong with either one. The X800, being lower clocked at stock, may give a little more headroom for overclocking, if you're into that. It looks like those two cards you pointed out have identical cooling solutions. I would just go with the cheaper of the two.

nope, I'm referring to the 800 xt: http://www.digital-daily.com/video/ati-radeon-x800xt/

Yes, if you overclock the x800, you should get better performance than an overclocked GT.
