Compare any two graphics cards:
Radeon R9 M295X vs Radeon R9 M390X
IntroThe Radeon R9 M295X uses a 28 nm design. AMD has set the core speed at 750 MHz. The GDDR5 memory is set to run at a frequency of 1375 MHz on this particular card. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.Compare all that to the Radeon R9 M390X, which makes use of a 28 nm design. AMD has clocked the core speed at 723 MHz. The GDDR5 memory is set to run at a speed of 1250 MHz on this card. It features 2048 SPUs along with 128 TAUs and 32 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthAs far as performance goes, the Radeon R9 M295X should in theory be just a bit superior to the Radeon R9 M390X overall. (explain)
Texel RateThe Radeon R9 M295X will be a small bit (more or less 4%) better at AF than the Radeon R9 M390X. (explain)
Pixel RateThe Radeon R9 M295X should be a small bit (more or less 4%) faster with regards to full screen anti-aliasing than the Radeon R9 M390X, and should be able to handle higher screen resolutions without losing too much performance. (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 max amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If 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 higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core 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 processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
