Compare any two graphics cards:
GeForce 8600 GT 256MB GDDR3 vs Radeon HD 6950
IntroThe GeForce 8600 GT 256MB GDDR3 has core speeds of 540 MHz on the GPU, and 700 MHz on the 256 MB of GDDR3 memory. It features 32 SPUs as well as 16 TAUs and 8 ROPs.Compare all that to the Radeon HD 6950, which uses a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 RAM works at a speed of 1250 MHz on this particular model. It features 1408 SPUs as well as 88 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6950, in theory, should perform a lot faster than the GeForce 8600 GT 256MB GDDR3 overall. (explain)
Texel RateThe Radeon HD 6950 should be quite a bit (more or less 715%) more effective at anisotropic filtering than the GeForce 8600 GT 256MB GDDR3. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 6950 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 maximum amount of information (counted in MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 are processed per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the 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 most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
