Compare any two graphics cards:
GeForce GTX 560 Ti 448 vs Radeon HD 4850 1GB
IntroThe GeForce GTX 560 Ti 448 has core clock speeds of 732 MHz on the GPU, and 900 MHz on the 1280 MB of GDDR5 RAM. It features 448 SPUs along with 56 Texture Address Units and 40 Rasterization Operator Units.Compare those specifications to the Radeon HD 4850 1GB, which uses a 55 nm design. AMD has clocked the core frequency at 625 MHz. The GDDR4 RAM is set to run at a frequency of 993 MHz on this model. It features 800(160x5) SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 560 Ti 448 should theoretically be a lot better than the Radeon HD 4850 1GB in general. (explain)
Texel RateThe GeForce GTX 560 Ti 448 should be quite a bit (more or less 64%) better at anisotropic filtering than the Radeon HD 4850 1GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 560 Ti 448 is superior to the Radeon HD 4850 1GB, and very much so. (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 Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once 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 higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of 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.
