Compare any two graphics cards:
GeForce GTX 275 vs Radeon HD 5850
IntroThe GeForce GTX 275 uses a 55 nm design. nVidia has set the core frequency at 633 MHz. The GDDR3 memory works at a speed of 1134 MHz on this specific card. It features 240 SPUs along with 80 TAUs and 28 Rasterization Operator Units.Compare those specifications to the Radeon HD 5850, which comes with GPU core speed of 725 MHz, and 1024 MB of GDDR5 RAM set to run at 1000 MHz through a 256-bit bus. It also is made up of 1440(288x5) Stream Processors, 72 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon HD 5850 should be just a bit faster than the GeForce GTX 275 overall. (explain)
Texel RateThe Radeon HD 5850 is a small bit (more or less 3%) better at AF than the GeForce GTX 275. (explain)
Pixel RateThe Radeon HD 5850 should be a lot (approximately 31%) better at full screen anti-aliasing than the GeForce GTX 275, and capable of handling higher resolutions while still performing well. (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: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
