Compare any two graphics cards:
GeForce 8800 GTS (G80) 320MB vs Radeon HD 4850 1GB
IntroThe GeForce 8800 GTS (G80) 320MB uses a 90 nm design. nVidia has clocked the core frequency at 513 MHz. The GDDR3 RAM runs at a frequency of 792 MHz on this card. It features 96 SPUs along with 48 TAUs and 20 Rasterization Operator Units.Compare those specifications to the Radeon HD 4850 1GB, which comes with a core clock speed of 625 MHz and a GDDR4 memory speed of 993 MHz. It also uses a 256-bit bus, and uses a 55 nm design. It is comprised of 800(160x5) SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 4850 1GB should perform a little bit faster than the GeForce 8800 GTS (G80) 320MB overall. (explain)
Texel RateThe Radeon HD 4850 1GB will be a small bit (more or less 2%) more effective at AF than the GeForce 8800 GTS (G80) 320MB. (explain)
Pixel RateThe GeForce 8800 GTS (G80) 320MB will be just a bit (about 3%) better at anti-aliasing than the Radeon HD 4850 1GB, and also capable of handling higher 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: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics 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 that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
