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 clocked the core speed at 822 MHz. The GDDR5 RAM works at a frequency of 1002 MHz on this particular card. It features 384 SPUs along with 64 TAUs and 32 Rasterization Operator Units.
Compare those specs to the Radeon HD 6570 (OEM) 2GB, which comes with core speeds of 650 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 480 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 560 Ti, in theory, should perform a lot faster than the Radeon HD 6570 (OEM) 2GB in general. (explain)
Texel RateThe GeForce GTX 560 Ti will be quite a bit (approximately 237%) better at texture filtering than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateThe GeForce GTX 560 Ti is much (about 406%) more effective at full screen anti-aliasing than the Radeon HD 6570 (OEM) 2GB, and also able to handle higher screen 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.
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 data (measured in megabytes per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's 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 applied in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock 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 lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
