Compare any two graphics cards:
Radeon HD 3870 X2 1GB vs Radeon R7 M260
IntroThe Radeon HD 3870 X2 1GB uses a 55 nm design. AMD has clocked the core frequency at 825 MHz. The GDDR4 RAM is set to run at a frequency of 1126 MHz on this specific card. It features 320(64x5) SPUs as well as 16 Texture Address Units and 16 Rasterization Operator Units.Compare those specifications to the Radeon R7 M260, which comes with a clock speed of 715 MHz and a DDR3 memory frequency of 1000 MHz. It also features a 64-bit bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon HD 3870 X2 1GB will be 801% quicker than the Radeon R7 M260 in general, because of its greater bandwidth. (explain)
Texel RateThe Radeon HD 3870 X2 1GB will be a lot (more or less 54%) faster with regards to AF than the Radeon R7 M260. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 3870 X2 1GB is a better choice, 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

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
