Compare any two graphics cards:
GeForce GTX 560 vs Radeon HD 4870 512MB
IntroThe GeForce GTX 560 features core clock speeds of 810 MHz on the GPU, and 1001 MHz on the 1024 MB of GDDR5 RAM. It features 336 SPUs along with 56 TAUs and 32 ROPs.Compare all that to the Radeon HD 4870 512MB, which uses a 55 nm design. AMD has clocked the core speed at 750 MHz. The GDDR5 memory runs at a speed of 900 MHz on this specific model. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthThe GeForce GTX 560 should theoretically be a bit faster than the Radeon HD 4870 512MB overall. (explain)
Texel RateThe GeForce GTX 560 will be much (approximately 51%) better at anisotropic filtering than the Radeon HD 4870 512MB. (explain)
Pixel RateThe GeForce GTX 560 will be a lot (about 116%) more effective at full screen anti-aliasing than the Radeon HD 4870 512MB, and able to handle 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 max amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the 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 the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
