Compare any two graphics cards:
GeForce GTX 560 Ti 448 vs Radeon HD 7850
IntroThe GeForce GTX 560 Ti 448 comes with core clock speeds of 732 MHz on the GPU, and 900 MHz on the 1280 MB of GDDR5 memory. It features 448 SPUs along with 56 Texture Address Units and 40 ROPs.
Compare all of that to the Radeon HD 7850, which uses a 28 nm design. ATi has clocked the core frequency at 860 MHz. The GDDR5 RAM runs at a speed of 1200 MHz on this particular model. It features 1024 SPUs as well as 64 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon HD 7850 should in theory be a small bit better than the GeForce GTX 560 Ti 448 overall. (explain)
Texel RateThe Radeon HD 7850 should be quite a bit (more or less 34%) faster with regards to anisotropic filtering than the GeForce GTX 560 Ti 448. (explain)
Pixel RateThe GeForce GTX 560 Ti 448 should be a little bit (about 6%) more effective at FSAA than the Radeon HD 7850, and also should be able to handle higher resolutions better. (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 information (in units of megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per 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 card will be at 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 video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
