Compare any two graphics cards:
GeForce GTX 260 Core 216 vs Radeon HD 4870 2GB
IntroThe GeForce GTX 260 Core 216 has a GPU clock speed of 576 MHz, and the 896 MB of GDDR3 RAM runs at 999 MHz through a 448-bit bus. It also is comprised of 216 SPUs, 72 TAUs, and 28 ROPs.Compare that to the Radeon HD 4870 2GB, which makes use of a 55 nm design. AMD has set the core frequency at 750 MHz. The GDDR5 memory works at a speed of 900 MHz on this model. It features 800(160x5) SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 4870 2GB will be 3% faster than the GeForce GTX 260 Core 216 in general, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTX 260 Core 216 is a lot (about 38%) faster with regards to AF 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 superior to the Radeon HD 4870 2GB, 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

Display Specifications
Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 are processed in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
