Compare any two graphics cards:
GeForce GTX 560 Ti vs Radeon HD 6570 (OEM) 2GB
IntroThe GeForce GTX 560 Ti features core speeds of 822 MHz on the GPU, and 1002 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs along with 64 Texture Address Units and 32 Rasterization Operator Units.
Compare all of that to the Radeon HD 6570 (OEM) 2GB, which features GPU clock speed of 650 MHz, and 1024 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also is comprised of 480 Stream Processors, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GTX 560 Ti should perform quite a bit faster than the Radeon HD 6570 (OEM) 2GB in general. (explain)
Texel RateThe GeForce GTX 560 Ti will be a lot (approximately 237%) more effective at anisotropic filtering than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateThe GeForce GTX 560 Ti should be quite a bit (approximately 406%) faster with regards to AA than the Radeon HD 6570 (OEM) 2GB, and should be capable of handling 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 largest amount of data (counted in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
