Compare any two graphics cards:
GeForce GTX 260 Core 216 vs Radeon HD 4850 X2 512MB
IntroThe GeForce GTX 260 Core 216 makes use of a 65 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 RAM works at a speed of 999 MHz on this particular card. It features 216 SPUs as well as 72 Texture Address Units and 28 ROPs.Compare those specs to the Radeon HD 4850 X2 512MB, which comes with clock speeds of 625 MHz on the GPU, and 993 MHz on the 512 MB of GDDR3 memory. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 4850 X2 512MB should be a small bit faster than the GeForce GTX 260 Core 216 overall. (explain)
Texel RateThe Radeon HD 4850 X2 512MB should be a lot (approximately 21%) better at texture filtering than the GeForce GTX 260 Core 216. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 4850 X2 512MB is superior to the GeForce GTX 260 Core 216, by a large margin. (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: Bandwidth is the max amount of data (measured in MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 most pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
