Compare any two graphics cards:
GeForce GTX 260 216SP 55 nm vs Radeon HD 6970
IntroThe GeForce GTX 260 216SP 55 nm makes use of a 55 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 RAM runs at a speed of 999 MHz on this specific model. It features 216 SPUs as well as 72 TAUs and 28 Rasterization Operator Units.Compare all of that to the Radeon HD 6970, which uses a 40 nm design. AMD has set the core speed at 880 MHz. The GDDR5 RAM works at a frequency of 1375 MHz on this card. It features 1536 SPUs along with 96 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 6970 should in theory be a lot better than the GeForce GTX 260 216SP 55 nm overall. (explain)
Texel RateThe Radeon HD 6970 should be much (more or less 104%) more effective at anisotropic filtering than the GeForce GTX 260 216SP 55 nm. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 6970 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: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units by the core 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 processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
