Compare any two graphics cards:
GeForce GTX 260 vs Radeon HD 6870
IntroThe GeForce GTX 260 comes with a GPU core clock speed of 576 MHz, and the 896 MB of GDDR3 memory is set to run at 999 MHz through a 448-bit bus. It also is made up of 192 SPUs, 64 Texture Address Units, and 28 ROPs.Compare those specifications to the Radeon HD 6870, which features GPU core speed of 900 MHz, and 1024 MB of GDDR5 memory running at 1050 MHz through a 256-bit bus. It also features 1120 Stream Processors, 56 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 6870 should in theory be a little bit superior to the GeForce GTX 260 overall. (explain)
Texel RateThe Radeon HD 6870 will be much (approximately 37%) faster with regards to texture filtering than the GeForce GTX 260. (explain)
Pixel RateIf running with lots of anti-aliasing 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: Memory bandwidth is the max amount of data (measured in MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better 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 a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
