Compare any two graphics cards:
Radeon R9 380X vs Radeon R9 M290X
IntroThe Radeon R9 380X comes with a clock frequency of 970 MHz and a GDDR5 memory speed of 1425 MHz. It also features a 256-bit memory bus, and makes use of a 28 nm design. It is made up of 2048 SPUs, 128 TAUs, and 32 ROPs.Compare all that to the Radeon R9 M290X, which uses a 28 nm design. AMD has clocked the core speed at 850 MHz. The GDDR5 memory is set to run at a frequency of 1200 MHz on this specific model. It features 1280 SPUs as well as 80 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon R9 380X should perform just a bit faster than the Radeon R9 M290X overall. (explain)
Texel RateThe Radeon R9 380X is a lot (more or less 83%) better at anisotropic filtering than the Radeon R9 M290X. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon R9 380X 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 max amount of information (counted in MB per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, it should 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 anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, 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 that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
