Compare any two graphics cards:
Radeon HD 4870 X2 vs Radeon R7 M260
IntroThe Radeon HD 4870 X2 makes use of a 55 nm design. AMD has set the core frequency at 750 MHz. The GDDR5 RAM is set to run at a speed of 900 MHz on this model. It features 800(160x5) SPUs as well as 40 TAUs and 16 ROPs.Compare those specs to the Radeon R7 M260, which uses a 28 nm design. AMD has set the core frequency at 715 MHz. The DDR3 memory runs at a frequency of 1000 MHz on this particular model. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically, the Radeon HD 4870 X2 should be a lot faster than the Radeon R7 M260 in general. (explain)
Texel RateThe Radeon HD 4870 X2 is a lot (more or less 250%) more effective at texture filtering than the Radeon R7 M260. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 4870 X2 is a better choice, by far. (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 (in units of MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
