Compare any two graphics cards:
Radeon R9 390 8G vs Radeon R9 M365X
IntroThe Radeon R9 390 8G features a clock speed of 1000 MHz and a GDDR5 memory speed of 1500 MHz. It also makes use of a 512-bit memory bus, and makes use of a 28 nm design. It is made up of 2560 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.Compare all that to the Radeon R9 M365X, which has a core clock frequency of 925 MHz and a GDDR5 memory frequency of 1125 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon R9 390 8G, in theory, should be much faster than the Radeon R9 M365X overall. (explain)
Texel RateThe Radeon R9 390 8G is a lot (more or less 332%) better at AF than the Radeon R9 M365X. (explain)
Pixel RateThe Radeon R9 390 8G is a lot (more or less 332%) better at FSAA than the Radeon R9 M365X, and should be able to handle higher screen resolutions better. (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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
