Compare any two graphics cards:
GeForce GTX 260 216SP 55 nm vs GeForce GTX 460 1GB
IntroThe GeForce GTX 260 216SP 55 nm has a clock frequency of 576 MHz and a GDDR3 memory frequency of 999 MHz. It also makes use of a 448-bit memory bus, and uses a 55 nm design. It is made up of 216 SPUs, 72 Texture Address Units, and 28 Raster Operation Units.Compare those specs to the GeForce GTX 460 1GB, which features a core clock frequency of 675 MHz and a GDDR5 memory frequency of 900 MHz. It also makes use of a 256-bit memory bus, and makes use of a 40 nm design. It is comprised of 336 SPUs, 56 TAUs, and 32 ROPs.

GeForce GTX 460 1GB wins(Based entirely on the benchmarks listed above)When combining all game benchmark scores on this page together, the GeForce GTX 460 1GB wins overall, by 69 FPS. Please note that we do not have the results of every benchmark ever done for these cards, so the results may differ wildly in different games.
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 460 1GB should be a bit faster than the GeForce GTX 260 216SP 55 nm overall. (explain)
Texel RateThe GeForce GTX 260 216SP 55 nm will be a small bit (about 10%) better at anisotropic filtering than the GeForce GTX 460 1GB. (explain)
Pixel RateThe GeForce GTX 460 1GB will be much (more or less 34%) faster with regards to anti-aliasing than the GeForce GTX 260 216SP 55 nm, and should be able to handle higher screen resolutions more effectively. (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. Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Specifications
Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
