Compare any two graphics cards:
GeForce 8800 GT 256MB vs Radeon HD 6570 (OEM) 2GB
IntroThe GeForce 8800 GT 256MB comes with clock speeds of 600 MHz on the GPU, and 700 MHz on the 256 MB of GDDR3 RAM. It features 112 SPUs along with 56 TAUs and 16 Rasterization Operator Units.Compare those specifications to the Radeon HD 6570 (OEM) 2GB, which makes use of a 40 nm design. AMD has set the core speed at 650 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this particular card. It features 480 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6570 (OEM) 2GB will be 43% quicker than the GeForce 8800 GT 256MB in general, because of its greater data rate. (explain)
Texel RateThe GeForce 8800 GT 256MB is a lot (about 115%) more effective at AF than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateThe GeForce 8800 GT 256MB is much (approximately 85%) better at FSAA than the Radeon HD 6570 (OEM) 2GB, and also capable of handling higher screen resolutions without slowing down too much. (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 max amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
