Well, here is Sapphire's page for their R9800PRO:

Doesn't say anything about clock speeds though, and the brochure isn't available yet...

LOL it's pulled again

[Jazzz]

Anandtech should be releasing a review of it later on today or maybe tomarrow. The R9800 is suppose to overclock well as well according to firingsquad

...so isn't it fortunate that I got a screen capture
As said, there's no info... But I just heard that their PDF's were there for a while too... Wonder if anyone has a copy?

wow. that's weird.

is the chip fabbed in UMC?

[Chrono_Wanderer]

WOW. note "smartshaders 2.1 and smoothvision 2.1"

must be PS2.0+ and VS2.0+

possibly 8x FSAA...

correct me if i m wrong, but i thought the R300 cannot really do 128-bit FP color precision right (limited to 96)? if that's the case R350 must be the bug fix...

now we can only hope a 'real" FAA 16x. but then... if ati actually does this.. they will use a new naming like this one...

ATI RevolutionarySuperDupaIntelligentSmoothingLineVisi on 10.0 or something similar...

thx tempest, for the screenshot

o yea... found it funny on the screenshot:

The Radeon 9800 Pro must be connected to the computer ?

Correct, R300 can only do 96-bit and what do you mean by the R350 is the bug fix?

And second, FAA is is inferior to Radeon's 6xFSAA IMO. Plus, as we all know it only does edges so it misses a bunch fo stuff. I think it was Beyond3D that has the best comparison SS.

The R350 is the R300 with some improvements to Hyper-Z III to the Z cache is improved and there have been some changes to the color compression to improve the AA performance.

The initial R350 will run at 380/340 on the 9800 Pro. Also, it seems that the R350 will still use a 0.15µ process.

Quoting from an AnadTech review of the 9800 Pro

At the same clock speeds the new R350 core is no less than 30% faster across the board (ed. than R300 core) with 4X AA and 8X Quality Aniso enabled, not too shabby at all. ATI's improvements in their compression algorithms and the memory controller clearly come in handy when AA and Anisotropic filtering are turned on, effectively making the Quality Anisotropic filtering mode a useable option with the Radeon 9800 Pro.

As well, AnadTech indicates that they were able to overclock the R350 to have it run at 420/380 and that yeilded about ~ 10% improvement.

9800: 0.15µ process
9600: 0.13µ process

From the HardOCP review:
"Editors Note: There is some confusion about 128-bit color here that I just want to clear up. The R350/9800 handles color precision in the very same way that the 9700/R300 does. They both support 128-bit floating point color but only support 96-bit (24/24/24/24) precision in the use of pixel shaders."

also from HardOCP, we will downclock the gffx5800 ultra to normal retail gffx5800 speeds.... Kyle don't like NV anymore, he is not cutting them any slack.

Tests done by TB, the maker of the great 3DAnalyze program have shown that most of this performance gains are not really in the core but in the new drivers. He forced the new R350 driver to work on his R300 and got up to 20% improvement with his "old" R9700Pro in AA/aniso.

way to go ATi...they fixed a few things, upped the speed for the show, and tweaked the drivers. So they sell a cheaper part for a premium price

[GNEP]

The tests done by Beyond3d (also using the same drivers for 9700PRO and 9800PRO, and downclocking the 9800PRO) seemed to suggest that in some circumstances, the 9800's core did have advantages - usually around 10% or so in terms of speed.

But the real tweaks to the core from R300 --> R350 seem to be to allow it to clock higher. Much like different cores of, say, the Athlon XP...

Which is no bad thing at all. Remember the 9800PRO is clocked higher than the 9700PRO, with room for more if you like...
