Compare any two graphics cards:
Radeon R7 260X vs Radeon R9 M385X
IntroThe Radeon R7 260X features a GPU clock speed of 1100 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1625 MHz through a 128-bit bus. It also is made up of 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.Compare all that to the Radeon R9 M385X, which comes with a clock frequency of 1100 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is made up of 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon R7 260X should be 8% faster than the Radeon R9 M385X in general, because of its greater data rate. (explain)
Texel RateBoth cards have exactly the same texel rate, so in theory they should be equally good at at anisotropic filtering. (explain)Pixel RateBoth cards have exactly the same pixel fill rate, so in theory they should be equally good at at full screen anti-aliasing, and be capable of handling the same resolutions. (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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR 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 speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
