Read that... In any case, that's the 12 pipe 6800 non ultra with clocks of 325/350. As you can see it scored about 8800 in 3DMark 2003. Take a look at the other game tests. Keeping in mind that the 6800 Ultra is faster than the 6800 Go Ultra, you can see where I'm saying max 1.5X the speed (at higher res of course) of the 6800 go. You may notice that the 6800Ultra does do more than 50% better than the 6800nu in some tests, but as they point out that's due to the 128MB VRAM on the non-ultra as compared to 256MB on the Ultra. That shouldn't factor in for the mobile chips as both have 256MB VRAM.
I've done quite a bit of work with computer hardware and was pretty active in several tech forums prior to this one so if I pour out a lot of technical stuff, don't think that I'm trying to scare you off. It's just that many people have preconceived notions about certain things and it kinda bugs me sometimes when they shout it out to the world without really
knowing what they're talking about... So this is just to clear it up a bit, not to belittle anyone.
As for the type of VRAM, it really doesn't matter. DDR1 and DDR3 are changed in only 2 major aspects.
1. GDDR3 runs at a default of ~1.8V while GDDR1 uses ~2.5V
2. GDDR3 can run at higher speeds because it actually uses 4bit instead of 2bit (of GDDR1) data prefetch. So when you see GDDR3 say 1100, it's actually running at 225MHz while GDDR1 at 1100 (if that were possible) would be running at 550MHz. Obviously, much harder for GDDR1 than GDDR3. There are no performance benefits of GDDR3 over GDDR1 at the same clocks. Absolutely none, unless they change the latencies. And for the most part GDDR3 latencies are actually higher
than GDDR1 latencies.
