Compare any two graphics cards:
GeForce GTX 465 vs Radeon HD 7870 XT
IntroThe GeForce GTX 465 features a clock speed of 607 MHz and a GDDR5 memory speed of 802 MHz. It also uses a 256-bit memory bus, and makes use of a 40 nm design. It features 352 SPUs, 44 TAUs, and 32 Raster Operation Units.Compare those specifications to the Radeon HD 7870 XT, which has core speeds of 925 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 RAM. It features 1536 SPUs as well as 96 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 7870 XT should in theory be a lot superior to the GeForce GTX 465 overall. (explain)
Texel RateThe Radeon HD 7870 XT is much (more or less 232%) faster with regards to texture filtering than the GeForce GTX 465. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 7870 XT is the winner, and very much so. (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 information (measured in megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the 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 could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines 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 output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
