Compare any two graphics cards:
GeForce GTX 260 vs Radeon HD 6570 (OEM) 1GB
IntroThe GeForce GTX 260 makes use of a 65 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 memory runs at a speed of 999 MHz on this card. It features 192 SPUs along with 64 Texture Address Units and 28 ROPs.Compare that to the Radeon HD 6570 (OEM) 1GB, which makes use of a 40 nm design. AMD has set the core frequency at 650 MHz. The GDDR3 memory works at a frequency of 900 MHz on this specific card. It features 480 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 260 should in theory be quite a bit better than the Radeon HD 6570 (OEM) 1GB in general. (explain)
Texel RateThe GeForce GTX 260 is a lot (about 136%) more effective at anisotropic filtering than the Radeon HD 6570 (OEM) 1GB. (explain)
Pixel RateThe GeForce GTX 260 is much (about 210%) more effective at full screen anti-aliasing than the Radeon HD 6570 (OEM) 1GB, and should be capable of handling higher resolutions while still performing well. (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 (counted in MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If 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 higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
