Compare any two graphics cards:
GeForce 8800 GT 512MB vs Radeon HD 6570 (OEM) 2GB
IntroThe GeForce 8800 GT 512MB uses a 65 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this specific card. It features 112 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.Compare all that to the Radeon HD 6570 (OEM) 2GB, which comes with GPU clock speed of 650 MHz, and 1024 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also is made up of 480 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6570 (OEM) 2GB is 11% quicker than the GeForce 8800 GT 512MB overall, due to its greater data rate. (explain)
Texel RateThe GeForce 8800 GT 512MB is much (approximately 115%) faster with regards to texture filtering than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateThe GeForce 8800 GT 512MB is quite a bit (more or less 85%) more effective at FSAA than the Radeon HD 6570 (OEM) 2GB, and able to handle higher 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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. In the case of 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, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
