Compare any two graphics cards:
GeForce GTX 560 Ti 448 vs Radeon HD 7850
IntroThe GeForce GTX 560 Ti 448 features a GPU clock speed of 732 MHz, and the 1280 MB of GDDR5 RAM runs at 900 MHz through a 320-bit bus. It also is made up of 448 Stream Processors, 56 Texture Address Units, and 40 ROPs.
Compare those specs to the Radeon HD 7850, which features a core clock frequency of 860 MHz and a GDDR5 memory speed of 1200 MHz. It also makes use of a 256-bit memory bus, and uses a 28 nm design. It is comprised of 1024 SPUs, 64 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Radeon HD 7850 should be a small bit faster than the GeForce GTX 560 Ti 448 overall. (explain)
Texel RateThe Radeon HD 7850 will be much (more or less 34%) better at anisotropic filtering than the GeForce GTX 560 Ti 448. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 560 Ti 448 is superior to the Radeon HD 7850, but not by far. (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 (measured in megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
