With the "6800" you have the stock 12 pixel pipes and 5 texture pipes,
128 megs of DDR1 SGram and 256 bit bus. The "6800GT" has stock 16 pixel
pipes and 6 texture pipes, 256 megs of DDR3 SGram and 256 bit bus.
Some while back, someone discovered that the pipes on the 6800 were
locked down to their stock number of 12 from 16 and 5 from 6 in the
cards BIOS. RivaTuner provided a way to unmask or unlock those pipes.
If the unmask worked and 'stuck' properly, you basically have a budget
GT with 128 megs of slower ram because all the pipes work. This is
called the 6800 softmod.
I have a 6800 that this mod did not work on. No sweat, it's simply a
6800.
Inglo has a 6800 that this mod DID work on, so his card is using 16
pixel pipes instead of 12 and 6 texture pipes instead of 5. This makes
for a noticeable improvment in overall performance in applications with
lots of big textures. Like games
The 6800 GT offers more stock clock speed and 256 megs of DDR3 SGram,
which is even more noticeable improvement in performance in those
applications.
This softmod puts the modded 6800 right between the stock 6800 and the
GT. It's a nice step too.
HIH,
