Compare any two graphics cards:
GeForce GTX 560 Ti 448 vs Radeon HD 7850
IntroThe GeForce GTX 560 Ti 448 makes use of a 40 nm design. nVidia has set the core speed at 732 MHz. The GDDR5 RAM is set to run at a frequency of 900 MHz on this card. It features 448 SPUs as well as 56 TAUs and 40 ROPs.
Compare all that to the Radeon HD 7850, which has a GPU core clock speed of 860 MHz, and 2048 MB of GDDR5 memory set to run at 1200 MHz through a 256-bit bus. It also is comprised of 1024 SPUs, 64 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, 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 quite a bit (more or less 34%) better at texture filtering than the GeForce GTX 560 Ti 448. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 560 Ti 448 is superior to the Radeon HD 7850, not by a very large margin though. (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 max amount of data (in units of megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units of the card by the core clock 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 processed in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record 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 clock speed. 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
