Compare any two graphics cards:
Radeon R9 M290X vs Radeon R9 M395X
IntroThe Radeon R9 M290X uses a 28 nm design. AMD has clocked the core frequency at 850 MHz. The GDDR5 RAM runs at a frequency of 1200 MHz on this particular card. It features 1280 SPUs along with 80 TAUs and 32 ROPs.Compare all of that to the Radeon R9 M395X, which makes use of a 28 nm design. AMD has set the core frequency at 723 MHz. The GDDR5 RAM works at a speed of 1250 MHz on this specific card. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon R9 M395X should in theory be a bit better than the Radeon R9 M290X overall. (explain)
Texel RateThe Radeon R9 M395X should be much (approximately 36%) faster with regards to texture filtering than the Radeon R9 M290X. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon R9 M290X is the winner, but it probably won't make a huge difference. (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 largest amount of information (counted in MB per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
