Compare any two graphics cards:
GeForce 9800 GTX+ vs Radeon HD 6950 2GB
IntroThe GeForce 9800 GTX+ makes use of a 55 nm design. nVidia has set the core frequency at 738 MHz. The GDDR3 memory works at a speed of 1100 MHz on this specific card. It features 128 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.Compare that to the Radeon HD 6950 2GB, which comes with core clock speeds of 800 MHz on the GPU, and 1250 MHz on the 2048 MB of GDDR5 RAM. It features 1408 SPUs along with 88 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 6950 2GB should theoretically be quite a bit better than the GeForce 9800 GTX+ in general. (explain)
Texel RateThe Radeon HD 6950 2GB is a lot (more or less 49%) more effective at texture filtering than the GeForce 9800 GTX+. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 6950 2GB is the winner, 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: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the 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 applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. 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 fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
