Does anyone notice that it has a 192-bit bus instead of the 128-bit bus the GTS 450 had? This is the version we were expecting to see. 750mhz GDDR5 (3000 effective) on my laptop GPU, GTX 460M, on the 192-bit bus yields 72GB/s on the Memory Bandwidth. 1000mhz GDDR5 hit 96GB/s on my past 768MB 460, so this 550 will match the 1GB model 460 for bandwidth. So memory won't be much of a problem.
The one question I have is how do you have a 1GB framebuffer with that kind of memory bus? That's a bit odd. Shouldn't it be 768MB or 1.5GB? I didn't think you could actually have a mismatching framebuffer and bus width. o_O

And 1GHz has been possible since the 4890...
Yet hitting 1Ghz on an NVIDIA card has been impossible until now. The fact that you can regularly hit 1GHz now for this side of the GPU industry is a feat on it's own. Edited by Imglidinhere - 3/14/11 at 11:15am
