Compare any two graphics cards:
GeForce GTX 260 Core 216 vs Radeon HD 4870 2GB
IntroThe GeForce GTX 260 Core 216 has a core clock frequency of 576 MHz and a GDDR3 memory speed of 999 MHz. It also features a 448-bit bus, and makes use of a 65 nm design. It features 216 SPUs, 72 Texture Address Units, and 28 Raster Operation Units.Compare all that to the Radeon HD 4870 2GB, which makes use of a 55 nm design. AMD has set the core speed at 750 MHz. The GDDR5 memory runs at a frequency of 900 MHz on this particular model. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 4870 2GB should perform a little bit faster than the GeForce GTX 260 Core 216 overall. (explain)
Texel RateThe GeForce GTX 260 Core 216 will be a lot (more or less 38%) more effective at anisotropic filtering than the Radeon HD 4870 2GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 260 Core 216 is a better choice, and very much so. (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: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If 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 high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the card will be at 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 chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core 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 fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
