Compare any two graphics cards:
GeForce GTX 560 Ti vs Radeon HD 5770
IntroThe GeForce GTX 560 Ti features a core clock frequency of 822 MHz and a GDDR5 memory speed of 1002 MHz. It also makes use of a 256-bit bus, and uses a 40 nm design. It features 384 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.
Compare those specifications to the Radeon HD 5770, which makes use of a 40 nm design. ATi has clocked the core speed at 850 MHz. The GDDR5 memory is set to run at a speed of 1200 MHz on this model. It features 800(160x5) SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 560 Ti is 67% faster than the Radeon HD 5770 overall, because of its higher bandwidth. (explain)
Texel RateThe GeForce GTX 560 Ti is quite a bit (about 55%) better at AF than the Radeon HD 5770. (explain)
Pixel RateThe GeForce GTX 560 Ti will be quite a bit (about 93%) more effective at AA than the Radeon HD 5770, and 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.
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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
