Compare any two graphics cards:
GeForce GTX 460 2GB vs Radeon HD 4790
IntroThe GeForce GTX 460 2GB has core clock speeds of 675 MHz on the GPU, and 900 MHz on the 2048 MB of GDDR5 memory. It features 336 SPUs along with 56 TAUs and 32 ROPs.Compare those specifications to the Radeon HD 4790, which uses a 55 nm design. AMD has clocked the core speed at 600 MHz. The GDDR5 RAM is set to run at a frequency of 800 MHz on this particular model. It features 640(128x5) SPUs along with 32 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the GeForce GTX 460 2GB is 13% quicker than the Radeon HD 4790 in general, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTX 460 2GB will be quite a bit (about 97%) more effective at texture filtering than the Radeon HD 4790. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 460 2GB is superior to the Radeon HD 4790, by a large margin. (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: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock 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 fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
