Compare any two graphics cards:
GeForce GTX 580 vs Radeon HD 6950 2GB
IntroThe GeForce GTX 580 comes with a clock frequency of 772 MHz and a GDDR5 memory frequency of 1002 MHz. It also features a 384-bit bus, and makes use of a 40 nm design. It is made up of 512 SPUs, 64 TAUs, and 48 Raster Operation Units.Compare all that to the Radeon HD 6950 2GB, which uses a 40 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 RAM runs at a frequency of 1250 MHz on this particular card. It features 1408 SPUs as well as 88 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 580 is 20% faster than the Radeon HD 6950 2GB overall, due to its greater bandwidth. (explain)
Texel RateThe Radeon HD 6950 2GB is a lot (about 42%) better at anisotropic filtering than the GeForce GTX 580. (explain)
Pixel RateThe GeForce GTX 580 is quite a bit (about 45%) faster with regards to AA than the Radeon HD 6950 2GB, and also able to handle higher resolutions without slowing down too much. (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 maximum amount of data (in units of 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 the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
