Compare any two graphics cards:
GeForce 9800 GT 512MB vs Radeon HD 6570 (OEM) 2GB
IntroThe GeForce 9800 GT 512MB comes with a clock frequency of 600 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 256-bit bus, and makes use of a 65/55 nm design. It features 112 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.Compare all that to the Radeon HD 6570 (OEM) 2GB, which uses a 40 nm design. AMD has clocked the core frequency at 650 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this particular model. It features 480 SPUs as well as 24 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6570 (OEM) 2GB should be 11% quicker than the GeForce 9800 GT 512MB in general, because of its higher bandwidth. (explain)
Texel RateThe GeForce 9800 GT 512MB will be much (more or less 115%) more effective at AF than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce 9800 GT 512MB is a better choice, and very much so. (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 largest amount of information (measured in megabytes per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the 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 the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
