Compare any two graphics cards:
GeForce GTX 285 1GB vs Radeon HD 6950
IntroThe GeForce GTX 285 1GB has a GPU core clock speed of 648 MHz, and the 1024 MB of GDDR3 memory is set to run at 1242 MHz through a 512-bit bus. It also is made up of 240 SPUs, 80 TAUs, and 32 Raster Operation Units.Compare all that to the Radeon HD 6950, which uses a 40 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 memory is set to run at a speed of 1250 MHz on this particular card. It features 1408 SPUs along with 88 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6950, in theory, should be a little bit faster than the GeForce GTX 285 1GB overall. (explain)
Texel RateThe Radeon HD 6950 will be much (more or less 36%) more effective at anisotropic filtering than the GeForce GTX 285 1GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 6950 is a better choice, 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 information (measured in MB per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
