Compare any two graphics cards:
GeForce GTX 260 Core 216 vs Radeon HD 4870 2GB
IntroThe GeForce GTX 260 Core 216 features clock 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 those specifications to the Radeon HD 4870 2GB, which features a core clock speed of 750 MHz and a GDDR5 memory frequency of 900 MHz. It also uses a 256-bit memory bus, and makes use of a 55 nm design. It is made up of 800(160x5) SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 4870 2GB should perform a little bit faster than the GeForce GTX 260 Core 216 in general. (explain)
Texel RateThe GeForce GTX 260 Core 216 should be a lot (approximately 38%) faster with regards to anisotropic filtering than the Radeon HD 4870 2GB. (explain)
Pixel RateThe GeForce GTX 260 Core 216 is much (about 34%) more effective at FSAA than the Radeon HD 4870 2GB, and should be capable of handling higher resolutions better. (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 information (counted in MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
