Compare any two graphics cards:
GeForce 8600 GS (OEM) vs Radeon HD 6570 (OEM) 1GB
IntroThe GeForce 8600 GS (OEM) makes use of a 80 nm design. nVidia has set the core frequency at 540 MHz. The DDR2 RAM is set to run at a speed of 400 MHz on this card. It features 32 SPUs as well as 16 TAUs and 8 ROPs.Compare that to the Radeon HD 6570 (OEM) 1GB, which comes with a core clock speed of 650 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It is comprised of 480 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6570 (OEM) 1GB will be 125% quicker than the GeForce 8600 GS (OEM) in general, because of its greater data rate. (explain)
Texel RateThe Radeon HD 6570 (OEM) 1GB will be quite a bit (about 81%) better at AF than the GeForce 8600 GS (OEM). (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 6570 (OEM) 1GB is the winner, though 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

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be moved over 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 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record 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 clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
