Compare any two graphics cards:
GeForce GTX 560 Ti vs Radeon HD 6570 (OEM) 2GB
IntroThe GeForce GTX 560 Ti makes use of a 40 nm design. nVidia has set the core speed at 822 MHz. The GDDR5 memory works at a frequency of 1002 MHz on this specific model. It features 384 SPUs as well as 64 Texture Address Units and 32 ROPs.
Compare all of that to the Radeon HD 6570 (OEM) 2GB, which makes use of a 40 nm design. AMD has clocked the core frequency at 650 MHz. The GDDR5 memory works at a speed of 1000 MHz on this particular card. It features 480 SPUs as well as 24 Texture Address Units and 8 ROPs.

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 in general, because of its greater data rate. (explain)
Texel RateThe GeForce GTX 560 Ti will be a lot (more or less 237%) more effective at anisotropic filtering than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateThe GeForce GTX 560 Ti will be a lot (more or less 406%) better at full screen anti-aliasing than the Radeon HD 6570 (OEM) 2GB, and also should be able to handle higher screen resolutions without slowing down too much. (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 (measured in megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 figure is calculated by multiplying the total texture units 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 per second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
