Radeon X1900 XTX To Score Over 11K? - VR-Zone

[[EOCF] Tim]

We came to know that Radeon X1900 XTX (R580) will officially be clocked at 650MHz core and 1550Mhz for the memory while the X1900 XT will be officially clocked at 625MHz / 1450MHz. The reason for the lower memory clocks for X1900 XT is unclear yet since the X1800XT is already clocked at 1.5GHz. It is also confirmed that R580 has 16 pipelines and 48 shader processors.

More interestingly, we heard faintly that an early sample of X1900 XTX clocked at 500MHz scored 10.2K in 3DMark05 so we can safely presume that the official X1900 XTX will score over 11K. We can expect availability at launch on 24th January and retailers are expected to have stocks a few days before the launch. However, NVIDIA won't just allow ATi to steal the performance crown from them so G71 will be their answer to R580 and it seems NVIDIA is confident that G71 will beat R580. All it takes is a highly clocked, 32 pipes G71 to stop R580.

Someone just posted on a Dutch forum that a default X1900XTX at 650/775 doesn't reach 11K in 3DM05 on a A64 4000+. So it has to be a faster CPU that they've tested it on. And he also stated that the XTX seems to do well in F.E.A.R. at 1600x1200/4xAA/8xHQAF, max detail - no soft shadows.

I was expecting better, considering how shader intensive '05 is, but 11k will do.

X1900 with 48 shaders does not looked very good with small fps boost than I thought, the improvement was coming from the tweaking of the core, the extra huge 48 shaders didnt give the fps big boost.

6800 Ultra at 425MHz with 16 pipelines scored around 5000 3DMark 05, 7800 GTX at 430MHz with 24 pipelines scored around 8000 3DMark 05 and 7800 GTX 512 at 580MHz scored near 10,000 3DMark05. If G71 at 700MHz with the same 24 pipelines, it will scored 11,000 3DMark 05 but with the bonus of extra 8 pipelines bring the total to 32 pipelines will scored around 14,000 3D Mark 05.

Avg 49fps.

(tested in same system/same settings: 7800GTX/512; 36fps. X1800XT; 39fps.)

Isn't 3Dmark2k5 more vertex shading limited than pixel shading limited?

Yes I read from some forums that 3DMark 2005 are vertex shaders limited.

[MUYA]

With 2 more vertex shading units? and relatively same clock speed, a vertex throughput increase of 25%? not bad :)

In this year i believe 3DMark05's scores wont be as much important as the last year because 3DMark06 is comming!!
i'm interested to see how the G71/R580 will fare in it ;)

Perhaps, soon or later, some benchmark or game will use a lot of branches with PS 3.0 & will see a nice difference between R5x0/G7x due to the misspredicted branch penalties. Perhaps 3D Mark 2006 or perhaps Alan Wake. That's the only weak point of the G7x, i think.

Yes, I cannot wait for 3DMark06, curious to see this generation, and next generation cards tested on it.

Well said.
