Compare any two graphics cards:
GeForce GTX 260 vs Radeon HD 5850
IntroThe GeForce GTX 260 features a core clock speed of 576 MHz and a GDDR3 memory speed of 999 MHz. It also uses a 448-bit memory bus, and makes use of a 65 nm design. It features 192 SPUs, 64 Texture Address Units, and 28 Raster Operation Units.Compare all of that to the Radeon HD 5850, which has core clock speeds of 725 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 1440(288x5) SPUs as well as 72 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 5850 should theoretically be a small bit superior to the GeForce GTX 260 overall. (explain)
Texel RateThe Radeon HD 5850 will be quite a bit (more or less 42%) better at AF than the GeForce GTX 260. (explain)
Pixel RateThe Radeon HD 5850 should be much (more or less 44%) better at full screen anti-aliasing than the GeForce GTX 260, and able to handle higher screen resolutions more effectively. (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 max amount of data (counted in megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
