Compare any two graphics cards:
GeForce GTX 460 SE vs Radeon HD 4790
IntroThe GeForce GTX 460 SE uses a 40 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR5 RAM works at a speed of 850 MHz on this specific card. It features 288 SPUs along with 48 TAUs and 32 ROPs.Compare that to the Radeon HD 4790, which features a core clock frequency of 600 MHz and a GDDR5 memory speed of 800 MHz. It also makes use of a 256-bit bus, and makes use of a 55 nm design. It is comprised of 640(128x5) SPUs, 32 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the GeForce GTX 460 SE should perform just a bit faster than the Radeon HD 4790 overall. (explain)
Texel RateThe GeForce GTX 460 SE is quite a bit (about 63%) better at texture filtering than the Radeon HD 4790. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 460 SE is superior to the Radeon HD 4790, by far. (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 Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the interface 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 4 instead. The higher the card's memory bandwidth, 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 processed in one second. This number is calculated by multiplying the total amount 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 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 chip could possibly record to its local memory in one 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 sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
