Compare any two graphics cards:
GeForce GTX 460 1GB vs GeForce GTX 480
IntroThe GeForce GTX 460 1GB uses a 40 nm design. nVidia has clocked the core speed at 675 MHz. The GDDR5 memory is set to run at a frequency of 900 MHz on this specific model. It features 336 SPUs along with 56 Texture Address Units and 32 ROPs.
Compare those specs to the GeForce GTX 480, which features a clock frequency of 700 MHz and a GDDR5 memory frequency of 924 MHz. It also makes use of a 384-bit memory bus, and uses a 40 nm design. It is comprised of 480 SPUs, 60 TAUs, and 48 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 480 will be 54% faster than the GeForce GTX 460 1GB in general, due to its greater data rate. (explain)
Texel RateThe GeForce GTX 480 should be a bit (about 11%) faster with regards to texture filtering than the GeForce GTX 460 1GB. (explain)
Pixel RateThe GeForce GTX 480 should be quite a bit (approximately 56%) faster with regards to FSAA than the GeForce GTX 460 1GB, and should be capable of handling higher resolutions without slowing down too much. (explain)
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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
