Compare any two graphics cards:
GeForce 9600 GT 512MB vs Radeon HD 4850 512MB
IntroThe GeForce 9600 GT 512MB has a GPU clock speed of 650 MHz, and the 512 MB of GDDR3 memory runs at 900 MHz through a 256-bit bus. It also is comprised of 64 SPUs, 32 TAUs, and 16 Raster Operation Units.Compare all that to the Radeon HD 4850 512MB, which makes use of a 55 nm design. AMD has clocked the core speed at 625 MHz. The GDDR3 RAM runs at a speed of 993 MHz on this model. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 4850 512MB should in theory be a little bit better than the GeForce 9600 GT 512MB in general. (explain)
Texel RateThe Radeon HD 4850 512MB is just a bit (more or less 20%) faster with regards to AF than the GeForce 9600 GT 512MB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce 9600 GT 512MB is the winner, but not by far. (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 largest amount of data (measured in MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
