Compare any two graphics cards:
GeForce GTX 260 vs Radeon HD 6570 (OEM) 1GB
IntroThe GeForce GTX 260 has a GPU core speed of 576 MHz, and the 896 MB of GDDR3 RAM is set to run at 999 MHz through a 448-bit bus. It also features 192 SPUs, 64 TAUs, and 28 ROPs.Compare those specs to the Radeon HD 6570 (OEM) 1GB, which comes with GPU core speed of 650 MHz, and 1024 MB of GDDR3 RAM running at 900 MHz through a 128-bit bus. It also is comprised of 480 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 260 should theoretically be a lot better than the Radeon HD 6570 (OEM) 1GB overall. (explain)
Texel RateThe GeForce GTX 260 will be quite a bit (approximately 136%) faster with regards to AF than the Radeon HD 6570 (OEM) 1GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 260 is superior to the Radeon HD 6570 (OEM) 1GB, 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 data (in units of MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount 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 better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. 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 lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
