Compare any two graphics cards:
GeForce GTX 560 Ti vs Radeon HD 5770
IntroThe GeForce GTX 560 Ti uses a 40 nm design. nVidia has clocked the core frequency at 822 MHz. The GDDR5 RAM works at a speed of 1002 MHz on this particular model. It features 384 SPUs along with 64 Texture Address Units and 32 Rasterization Operator Units.
Compare that to the Radeon HD 5770, which makes use of a 40 nm design. ATi has set the core speed at 850 MHz. The GDDR5 memory runs at a speed of 1200 MHz on this particular model. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 560 Ti should theoretically be a lot better than the Radeon HD 5770 in general. (explain)
Texel RateThe GeForce GTX 560 Ti should be quite a bit (about 55%) better at anisotropic filtering than the Radeon HD 5770. (explain)
Pixel RateThe GeForce GTX 560 Ti is a lot (about 93%) more effective at anti-aliasing than the Radeon HD 5770, and will be able to handle higher screen resolutions more effectively. (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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high 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 amount of texture units of the card by the core clock 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 that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
