Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 260 216SP 55 nm 171 Watts
GeForce GTX 470 215 Watts
Difference: 44 Watts (26%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 470 should be 20% quicker than the GeForce GTX 260 216SP 55 nm overall, due to its higher bandwidth. (explain)

GeForce GTX 470 133920 MB/sec
GeForce GTX 260 216SP 55 nm 111888 MB/sec
Difference: 22032 (20%)

Texel Rate

The GeForce GTX 260 216SP 55 nm is a lot (more or less 22%) better at anisotropic filtering than the GeForce GTX 470. (explain)

GeForce GTX 260 216SP 55 nm 41472 Mtexels/sec
GeForce GTX 470 33992 Mtexels/sec
Difference: 7480 (22%)

Pixel Rate

The GeForce GTX 470 is quite a bit (about 51%) more effective at FSAA than the GeForce GTX 260 216SP 55 nm, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 470 24280 Mpixels/sec
GeForce GTX 260 216SP 55 nm 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: Bandwidth is the largest amount of information (counted in megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
