Compare any two graphics cards:
GeForce GTX 460 SE vs Radeon HD 4870 2GB
IntroThe GeForce GTX 460 SE comes with a clock speed of 650 MHz and a GDDR5 memory speed of 850 MHz. It also makes use of a 256-bit bus, and makes use of a 40 nm design. It features 288 SPUs, 48 TAUs, and 32 ROPs.Compare those specifications to the Radeon HD 4870 2GB, which has GPU clock speed of 750 MHz, and 2048 MB of GDDR5 memory running at 900 MHz through a 256-bit bus. It also features 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthAs far as performance goes, the Radeon HD 4870 2GB should in theory be a little bit superior to the GeForce GTX 460 SE overall. (explain)
Texel RateThe GeForce GTX 460 SE should be a small bit (more or less 4%) faster with regards to texture filtering than the Radeon HD 4870 2GB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 460 SE is the winner, 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 max amount of data (counted in megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, 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, High Dynamic Range 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 figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
