Compare any two graphics cards:
GeForce GTX 570 vs Radeon HD 3470 512MB
IntroThe GeForce GTX 570 features a GPU clock speed of 732 MHz, and the 1280 MB of GDDR5 RAM runs at 950 MHz through a 320-bit bus. It also is made up of 480 SPUs, 60 Texture Address Units, and 40 Raster Operation Units.Compare all of that to the Radeon HD 3470 512MB, which makes use of a 55 nm design. AMD has set the core frequency at 800 MHz. The GDDR3 memory works at a frequency of 950 MHz on this specific card. It features 40(8x5) SPUs as well as 4 Texture Address Units and 4 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe GeForce GTX 570, in theory, should be quite a bit faster than the Radeon HD 3470 512MB overall. (explain)
Texel RateThe GeForce GTX 570 will be a lot (approximately 1273%) better at AF than the Radeon HD 3470 512MB. (explain)
Pixel RateThe GeForce GTX 570 will be a lot (about 815%) better at full screen anti-aliasing than the Radeon HD 3470 512MB, and 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: Memory bandwidth is the max amount of information (measured in MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
