Why does the r600 look better on paper but not beat the g80?

post #1 of 30

Ok.

SO basiclly the 2900xt has 320 pixel shaders and the 8800 128 the r600 is a 512bit memory interface the 8800 384.

Why is it not better?

Personally I think its just a failure. By the paper specs it should whoop a G80 but it don't. It barely beats out a 8800GTS. And in some tests it loses. All of the ATI fanboys blame it on drivers.

could drivers cause that much of a performance loss?

No. Drivers can make a difference, but not that big.

Yes, but it doesn't mean that's the cause in this case.

Nvidia rigged the 8800 with some kind of magic.

im no ATI fanboy (never owned an ATI card so there) and with all the specs past even the GTX, there's got to be something that once they fix it will shoot up in benchies.. I just dont know what it is, naturally i want to say drivers, but with that much of a performance gap i really dont know.

The benchmarks, such as 3DMark06, are not far off between the 8800 GTX and HD 2900XT in many cases. It's the games that are bringing up the discrepancies, and usually this is due to drivers and the support therein, so that is why many people are suggesting that drivers are the issue. It doesn't necessarily have to do with people being fanboys.

It is very annoying that people are often labeled "fanboys" because they disagree with someone in the opposite camp.

It does look sweet on paper, doesn't it?

Most of those cool features you see on spec. sheets are not being fully utilized due to drivers, and games not being coded for it yet. We have already seen (on both nvidia and ATI camps) that a simple driver update could dramatically increase performance on a card.
