Mr obvious. Ofcourse future cards are faster with better features - why else would folks upgrade and buy them?
And I think you underestimate the ENORMOUS effort in architecture, design, floorplanning, validation, etc to get even chips as similar as 9800GT and 9600GT made. FYI 5800fx and 7900GTX were both DX9, but they are very very different.
Does it really matter? The means to an end? R600 doesn't have either 2D core or correctly working AA hardware. Yet you can surf web and play games with AA.
Obviously fake
Ghz -> GB = 1000000 / 1024^2 = 0.9313 GiB
512bit DDR = 512 * 2 / 8 = 128 (384=96, 320=80)
For GDDR5 double the clock rate shown, because GDDR5 fetches twice #bits at a time.
(if you dont use the Ghz->GB conversion factor, you will get same number as GPU-Z)
So, for your GTX295: (512/4) x 1.512Ghz = 128 x 1.512 x 0.9313 = 180.2 GigaBytes/s (GiB/s)
GTX480 from screenshot would be: (384/4) x 1.8 x 0.9313 = 160.9 GigaBytes/s (GiB/s)
For reference 5870: (256/4) x 2.4 x 0.9313 = 143.0 GigaBytes/s (GiB/s)
Almighty GTX480 only a smidgen ahead ... pff.. marketing PR wont stand for that.
Using same clocks as 5870, 480 will be 50% more, or 214.6GiB/s (or 230GB/s in marketing speak - very close to 5970's 256GB/s!!)
