Compare any two graphics cards:
GeForce 8800 GTS (G92) vs Radeon HD 4850 2GB
IntroThe GeForce 8800 GTS (G92) uses a 65 nm design. nVidia has clocked the core speed at 650 MHz. The GDDR3 memory works at a frequency of 970 MHz on this particular model. It features 128 SPUs as well as 64 Texture Address Units and 16 ROPs.Compare all that to the Radeon HD 4850 2GB, which has a core clock speed of 625 MHz and a GDDR4 memory frequency of 993 MHz. It also features a 256-bit memory bus, and uses a 55 nm design. It features 800(160x5) SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4850 2GB should in theory be a little bit faster than the GeForce 8800 GTS (G92) overall. (explain)
Texel RateThe GeForce 8800 GTS (G92) should be a lot (more or less 66%) more effective at AF than the Radeon HD 4850 2GB. (explain)
Pixel RateThe GeForce 8800 GTS (G92) will be a little bit (more or less 4%) more effective at full screen anti-aliasing than the Radeon HD 4850 2GB, and also will be able to handle higher screen resolutions more effectively. (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 (in units of MB per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once 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 anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number 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 processed per second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core 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 quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
