Compare any two graphics cards:
GeForce GTX 280 vs Radeon HD 5770
IntroThe GeForce GTX 280 uses a 65 nm design. nVidia has set the core frequency at 602 MHz. The GDDR3 RAM is set to run at a frequency of 1107 MHz on this model. It features 240 SPUs as well as 80 Texture Address Units and 32 ROPs.Compare those specifications to the Radeon HD 5770, which comes with a clock frequency of 850 MHz and a GDDR5 memory speed of 1200 MHz. It also uses a 128-bit bus, and uses a 40 nm design. It is comprised of 800(160x5) SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 280, in theory, should perform quite a bit faster than the Radeon HD 5770 overall. (explain)
Texel RateThe GeForce GTX 280 should be quite a bit (approximately 42%) faster with regards to AF than the Radeon HD 5770. (explain)
Pixel RateThe GeForce GTX 280 should be much (about 42%) more effective at AA than the Radeon HD 5770, and will be able to handle higher 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 largest amount of data (counted in MB per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
