Compare any two graphics cards:
GeForce GTX 470 vs Radeon HD 4870 1GB
IntroThe GeForce GTX 470 comes with a core clock speed of 607 MHz and a GDDR5 memory frequency of 837 MHz. It also uses a 320-bit bus, and makes use of a 40 nm design. It features 448 SPUs, 56 Texture Address Units, and 40 ROPs.Compare those specifications to the Radeon HD 4870 1GB, which comes with GPU core speed of 750 MHz, and 1024 MB of GDDR5 memory running at 900 MHz through a 256-bit bus. It also features 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 470 should theoretically be a little bit faster than the Radeon HD 4870 1GB overall. (explain)
Texel RateThe GeForce GTX 470 will be a little bit (approximately 13%) faster with regards to texture filtering than the Radeon HD 4870 1GB. (explain)
Pixel RateThe GeForce GTX 470 should be quite a bit (approximately 102%) more effective at FSAA than the Radeon HD 4870 1GB, and will be capable of handling higher resolutions without slowing down too much. (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 largest amount of data (measured in megabytes per second) that can be moved 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. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core 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 rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
