What are the differences between 6800, 6800GT and 6800 Ultra?

[Creole]

I m just wondering what are the main differences between these three boards? Is it just clock speed or are there hardware differences also?

Clockspeeds, Pipelines and Onboard Memory:

6800 - 12 Pipelines, 128MB, 325MHz/700MHz

6800 GT - 16 Pipelines, 256MB, 350MHz/1GHz

6800 Ultra - 16 Pipelines, 256MB, 400MHz/1.1GHz

Some brand like BFG and EVGA ship their ULTRAs at 425/1100 though.

6800 Ultra - 16 Pipelines, 256MB, 400MHz/1.1GHz


Also, 6800 has 5 vertex processors, GT and Ultra come with 6. 6800-cards have DDR-1 memory, most GTs and Ultras have DDR-3. Asus makes a bastard GT-edition with DDR-1 memory.

yea, my ultra also came at 425mhz... but I know most of them are 400

XFX has their ultras at 450/1100.

XFX has their ultras at 450/1100.

450/1200 actually, unless they've started shipping new card revisions clocked at the lower speed.

I guess the bastard edition can be listed also, using the format chosen by jackUp. ;)

Asus V9999GT/TD ("6800GT/6800 -bastard edition") - 16 Pipelines, 128MB, 350MHz/700MHz

The hardware differences are quite trivial. It is, more or less, just a matter of different quality components allowing different frequencys. The cards do the same tricks -- more expencive ones just do it faster.

So would a reagular 68000 be a worthwile upgrade from a Radeon 9700 Pro.

And dispite that it is quite a performer too, would be a great card in SLi, they also have a 6800GT 256MB 350/1GHz also.

All GT's are 256mb and run at 350/1ghz...except the BFG, that runs at 370/1ghz

yes because of the 4 extra pipelines. You would be better served by springing for the GT though.

[Lemur.fi]

I probably would not upgrade from 9700 Pro myself. Playing newer titles like Farcry for example, the performance difference would be noticiable though.

Bzzt. Thank you for playing. This ASUS GT has 128MB RAM and runs at 350/700:
