Compare any two graphics cards:
Radeon R9 290 vs Radeon R9 M395X
IntroThe Radeon R9 290 makes use of a 28 nm design. AMD has set the core speed at 800 MHz. The GDDR5 memory works at a speed of 1250 MHz on this particular model. It features 2560 SPUs along with 160 TAUs and 64 ROPs.Compare those specs to the Radeon R9 M395X, which comes with core clock speeds of 723 MHz on the GPU, and 1250 MHz on the 4096 MB of GDDR5 memory. It features 2048 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon R9 290 will be 100% faster than the Radeon R9 M395X overall, because of its greater data rate. (explain)
Texel RateThe Radeon R9 290 will be much (more or less 38%) faster with regards to anisotropic filtering than the Radeon R9 M395X. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon R9 290 is the winner, 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 maximum amount of data (in units of MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once 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 are processed per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the 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 most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
