Compare any two graphics cards:
GeForce GTS 250 1GB vs Radeon HD 4850 X2 512MB
IntroThe GeForce GTS 250 1GB has a clock speed of 738 MHz and a GDDR3 memory speed of 1100 MHz. It also uses a 256-bit bus, and makes use of a 65/55 nm design. It is made up of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.Compare those specifications to the Radeon HD 4850 X2 512MB, which comes with GPU core speed of 625 MHz, and 512 MB of GDDR3 memory running at 993 MHz through a 256-bit bus. It also features 800(160x5) SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4850 X2 512MB should theoretically be quite a bit faster than the GeForce GTS 250 1GB in general. (explain)
Texel RateThe Radeon HD 4850 X2 512MB should be just a bit (about 6%) faster with regards to texture filtering than the GeForce GTS 250 1GB. (explain)
Pixel RateThe Radeon HD 4850 X2 512MB is quite a bit (approximately 69%) better at FSAA than the GeForce GTS 250 1GB, and also 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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units 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 rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
