Compare any two graphics cards:
GeForce GTX 470 vs Radeon HD 6870
IntroThe GeForce GTX 470 features a core clock speed of 607 MHz and a GDDR5 memory speed of 837 MHz. It also features a 320-bit bus, and makes use of a 40 nm design. It features 448 SPUs, 56 TAUs, and 40 Raster Operation Units.Compare that to the Radeon HD 6870, which features a clock frequency of 900 MHz and a GDDR5 memory speed of 1050 MHz. It also uses a 256-bit memory bus, and makes use of a 40 nm design. It is made up of 1120 SPUs, 56 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6870, in theory, should be just a bit faster than the GeForce GTX 470 overall. (explain)
Texel RateThe Radeon HD 6870 will be quite a bit (approximately 48%) better at anisotropic filtering than the GeForce GTX 470. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 6870 is superior to the GeForce GTX 470, though only just barely. (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 max amount of data (measured in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of 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 per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
