GeForce GTX 260 vs GeForce GTX 470

Intro

The GeForce GTX 260 features a clock frequency of 576 MHz and a GDDR3 memory speed of 999 MHz. It also makes use of a 448-bit memory bus, and makes use of a 65 nm design. It features 192 SPUs, 64 TAUs, and 28 Raster Operation Units.

Compare all that to the GeForce GTX 470, which comes with a core clock speed of 607 MHz and a GDDR5 memory speed of 837 MHz. It also uses a 320-bit bus, and uses a 40 nm design. It is comprised of 448 SPUs, 56 Texture Address Units, and 40 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 260 182 Watts
GeForce GTX 470 215 Watts
Difference: 33 Watts (18%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 470 will be 20% faster than the GeForce GTX 260 in general, because of its higher data rate. (explain)

GeForce GTX 470 133920 MB/sec
GeForce GTX 260 111888 MB/sec
Difference: 22032 (20%)

Texel Rate

The GeForce GTX 260 is just a bit (about 8%) better at anisotropic filtering than the GeForce GTX 470. (explain)

GeForce GTX 260 36864 Mtexels/sec
GeForce GTX 470 33992 Mtexels/sec
Difference: 2872 (8%)

Pixel Rate

The GeForce GTX 470 should be much (about 51%) better at anti-aliasing than the GeForce GTX 260, and will be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 470 24280 Mpixels/sec
GeForce GTX 260 16128 Mpixels/sec
Difference: 8152 (51%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
