Compare any two graphics cards:
Radeon HD 3870 X2 512MB vs Radeon R7 M260X
IntroThe Radeon HD 3870 X2 512MB uses a 55 nm design. AMD has clocked the core speed at 825 MHz. The GDDR3 memory works at a frequency of 900 MHz on this specific card. It features 320(64x5) SPUs along with 16 Texture Address Units and 16 ROPs.Compare that to the Radeon R7 M260X, which comes with core clock speeds of 825 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 RAM. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon HD 3870 X2 512MB will be 80% faster than the Radeon R7 M260X overall, due to its higher data rate. (explain)
Texel RateThe Radeon HD 3870 X2 512MB is quite a bit (about 33%) faster with regards to AF than the Radeon R7 M260X. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 3870 X2 512MB is superior to the Radeon R7 M260X, 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 information (counted in megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units of the card 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 in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video 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 core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
