Compare any two graphics cards:
GeForce GTX 560 Ti vs Radeon HD 6570 (OEM) 2GB
IntroThe GeForce GTX 560 Ti has a core clock speed of 822 MHz and a GDDR5 memory frequency of 1002 MHz. It also makes use of a 256-bit memory bus, and makes use of a 40 nm design. It is comprised of 384 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.
Compare those specifications to the Radeon HD 6570 (OEM) 2GB, which uses a 40 nm design. AMD has set the core speed at 650 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this card. It features 480 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 560 Ti should be 100% quicker than the Radeon HD 6570 (OEM) 2GB overall, because of its greater data rate. (explain)
Texel RateThe GeForce GTX 560 Ti is quite a bit (approximately 237%) more effective at anisotropic filtering than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateThe GeForce GTX 560 Ti will be quite a bit (approximately 406%) better at AA than the Radeon HD 6570 (OEM) 2GB, and should be able to handle higher screen resolutions without losing too much performance. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the 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 most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out 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 rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
