Consider the following statement:
If that's true and I believe it is then I'm going to use some reverse logic to theorize the following:Nvidia’s GeForce 9800 GTX features 16 ROPs. The ROPs are split into four clusters – each is able to process four pixels per clock and is also connected to a 64-bit memory interface. This means that there’s a 256-bit memory interface on the GPU and it connects out to eight 64MB GDDR3 DRAMs, making a total of 512MB of video memory.
Nvidia’s GeForce GTX280 features 32 ROPs. The ROPs are probably split into eight (dividing 32 by 4) clusters – each is able to process four pixels per clock and is also connected to a 64-bit memory interface. This means that there’s a 512-bit memory interface on the GPU and it connects out to sixteen 64MB GDDR3 DRAMs, making a total of 1GB of video memory.
Nvidia’s GeForce GTX260 features 28 ROPs. The ROPs are probably split into seven (dividing 28 by 4) clusters – each is able to process four pixels per clock and is also connected to a 64-bit memory interface. This means that there’s a 448-bit memory interface on the GPU and it connects out to fourteen 64MB GDDR3 DRAMs, making a total of 896MB of video memory.
I know that I've seen how many memory chips there are on these boards somewhere but I didn't take to time to see it is 16 and 14 as I stated above.
Are we talking about the same clusters?
