Compare any two graphics cards:
GeForce GTX 460 2GB vs Radeon HD 6870
IntroThe GeForce GTX 460 2GB features a GPU core clock speed of 675 MHz, and the 2048 MB of GDDR5 memory runs at 900 MHz through a 256-bit bus. It also is made up of 336 SPUs, 56 TAUs, and 32 ROPs.Compare those specs to the Radeon HD 6870, which makes use of a 40 nm design. AMD has set the core frequency at 900 MHz. The GDDR5 RAM works at a speed of 1050 MHz on this particular model. It features 1120 SPUs along with 56 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6870, in theory, should perform a small bit faster than the GeForce GTX 460 2GB overall. (explain)
Texel RateThe Radeon HD 6870 will be quite a bit (about 33%) more effective at texture filtering than the GeForce GTX 460 2GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 6870 is the winner, 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 data (counted in megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core 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 also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
