Compare any two graphics cards:
GeForce 8800 GTX vs Radeon HD 6950 2GB
IntroThe GeForce 8800 GTX comes with a clock speed of 575 MHz and a GDDR3 memory speed of 900 MHz. It also features a 384-bit memory bus, and makes use of a 90 nm design. It is comprised of 128 SPUs, 64 TAUs, and 24 Raster Operation Units.Compare those specs to the Radeon HD 6950 2GB, which makes use of a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory is set to run at a frequency of 1250 MHz on this card. It features 1408 SPUs as well as 88 TAUs and 32 Rasterization Operator Units.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6950 2GB will be 85% quicker than the GeForce 8800 GTX overall, because of its higher bandwidth. (explain)
Texel RateThe Radeon HD 6950 2GB will be quite a bit (more or less 91%) better at AF than the GeForce 8800 GTX. (explain)
Pixel RateThe Radeon HD 6950 2GB is a lot (more or less 86%) faster with regards to anti-aliasing than the GeForce 8800 GTX, and capable of handling higher resolutions better. (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 data (measured in megabytes per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core 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 is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
