Compare any two graphics cards:
GeForce GTX 470 vs Radeon HD 5850
IntroThe GeForce GTX 470 makes use of a 40 nm design. nVidia has set the core speed at 607 MHz. The GDDR5 RAM works at a frequency of 837 MHz on this specific card. It features 448 SPUs as well as 56 Texture Address Units and 40 ROPs.Compare that to the Radeon HD 5850, which features core clock speeds of 725 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 1440(288x5) SPUs along with 72 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 470 is 5% faster than the Radeon HD 5850 in general, because of its greater bandwidth. (explain)
Texel RateThe Radeon HD 5850 is much (about 54%) faster with regards to texture filtering than the GeForce GTX 470. (explain)
Pixel RateThe GeForce GTX 470 will be a bit (approximately 5%) faster with regards to anti-aliasing than the Radeon HD 5850, and should 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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 can be applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
