Compare any two graphics cards:
GeForce GTX 260 Core 216 vs Radeon HD 4870 512MB
IntroThe GeForce GTX 260 Core 216 features core speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 memory. It features 216 SPUs as well as 72 TAUs and 28 Rasterization Operator Units.Compare all of that to the Radeon HD 4870 512MB, which has a clock speed of 750 MHz and a GDDR5 memory speed of 900 MHz. It also features a 256-bit bus, and uses a 55 nm design. It is made up of 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 4870 512MB is 3% quicker than the GeForce GTX 260 Core 216 in general, because of its higher data rate. (explain)
Texel RateThe GeForce GTX 260 Core 216 will be much (more or less 38%) better at anisotropic filtering than the Radeon HD 4870 512MB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 260 Core 216 is a better choice, by far. (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

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's 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 rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
