Compare any two graphics cards:
GeForce 9800 GT 512MB vs Radeon HD 6570 (OEM) 2GB
IntroThe GeForce 9800 GT 512MB uses a 65/55 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 memory runs at a speed of 900 MHz on this model. It features 112 SPUs along with 56 Texture Address Units and 16 ROPs.Compare those specifications to the Radeon HD 6570 (OEM) 2GB, which comes with a clock frequency of 650 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It is comprised of 480 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6570 (OEM) 2GB should be 11% faster than the GeForce 9800 GT 512MB in general, because of its higher data rate. (explain)
Texel RateThe GeForce 9800 GT 512MB will be a lot (about 115%) faster with regards to anisotropic filtering than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce 9800 GT 512MB is superior to the Radeon HD 6570 (OEM) 2GB, 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 moved across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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.
