Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 460 2GB 160 Watts
GeForce GTX 280 236 Watts
Difference: 76 Watts (48%)

Memory Bandwidth

Theoretically, the GeForce GTX 280 should perform quite a bit faster than the GeForce GTX 460 2GB overall. (explain)

GeForce GTX 280 141696 MB/sec
GeForce GTX 460 2GB 115200 MB/sec
Difference: 26496 (23%)

Texel Rate

The GeForce GTX 280 will be much (more or less 27%) more effective at anisotropic filtering than the GeForce GTX 460 2GB. (explain)

GeForce GTX 280 48160 Mtexels/sec
GeForce GTX 460 2GB 37800 Mtexels/sec
Difference: 10360 (27%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 460 2GB is superior to the GeForce GTX 280, not by a very large margin though. (explain)

GeForce GTX 460 2GB 21600 Mpixels/sec
GeForce GTX 280 19264 Mpixels/sec
Difference: 2336 (12%)

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 max amount of information (measured in MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. 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 many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
