Compare any two graphics cards:
GeForce GTX 560 vs Radeon HD 4870 2GB
IntroThe GeForce GTX 560 comes with a clock speed of 810 MHz and a GDDR5 memory speed of 1001 MHz. It also features a 256-bit bus, and makes use of a 40 nm design. It features 336 SPUs, 56 TAUs, and 32 Raster Operation Units.Compare those specifications to the Radeon HD 4870 2GB, which features a GPU core clock speed of 750 MHz, and 2048 MB of GDDR5 RAM running at 900 MHz through a 256-bit bus. It also features 800(160x5) Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthThe GeForce GTX 560 should in theory perform a small bit faster than the Radeon HD 4870 2GB overall. (explain)
Texel RateThe GeForce GTX 560 should be quite a bit (approximately 51%) more effective at anisotropic filtering than the Radeon HD 4870 2GB. (explain)
Pixel RateThe GeForce GTX 560 will be a lot (about 116%) faster with regards to AA than the Radeon HD 4870 2GB, and should be able to handle 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 maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units by the core 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 per second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock 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 output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
