Compare any two graphics cards:
GeForce 8800 GTS (G80) 640MB vs Radeon HD 6570 (OEM) 2GB
IntroThe GeForce 8800 GTS (G80) 640MB uses a 90 nm design. nVidia has clocked the core speed at 513 MHz. The GDDR3 memory is set to run at a speed of 792 MHz on this particular card. It features 96 SPUs as well as 48 TAUs and 20 ROPs.Compare all that to the Radeon HD 6570 (OEM) 2GB, which features GPU clock speed of 650 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also features 480 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon HD 6570 (OEM) 2GB should perform just a bit faster than the GeForce 8800 GTS (G80) 640MB overall. (explain)
Texel RateThe GeForce 8800 GTS (G80) 640MB will be quite a bit (about 58%) more effective at AF than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce 8800 GTS (G80) 640MB is a better choice, 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: Memory bandwidth is the max amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 can be applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
