Compare any two graphics cards:
Radeon R9 M390X vs Radeon RX 460 2GB
IntroThe Radeon R9 M390X has a GPU clock speed of 723 MHz, and the 4096 MB of GDDR5 RAM runs at 1250 MHz through a 256-bit bus. It also is comprised of 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.Compare those specs to the Radeon RX 460 2GB, which uses a 14 nm design. AMD has set the core speed at 1090 MHz. The GDDR5 RAM works at a speed of 1750 MHz on this model. It features 896 SPUs along with 56 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 M390X, in theory, should perform a lot faster than the Radeon RX 460 2GB overall. (explain)
Texel RateThe Radeon R9 M390X is much (more or less 52%) better at texture filtering than the Radeon RX 460 2GB. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon R9 M390X is a better choice, and very much so. (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 information (in units of megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, 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 number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at 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 video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
