Compare any two graphics cards:
Radeon R9 380 4G vs Radeon R9 M290X
IntroThe Radeon R9 380 4G uses a 28 nm design. AMD has set the core speed at 970 MHz. The GDDR5 RAM works at a speed of 1425 MHz on this card. It features 1792 SPUs as well as 112 TAUs and 32 Rasterization Operator Units.Compare those specs to the Radeon R9 M290X, which features a core clock frequency of 850 MHz and a GDDR5 memory frequency of 1200 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It is made up of 1280 SPUs, 80 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 380 4G should in theory perform a bit faster than the Radeon R9 M290X in general. (explain)
Texel RateThe Radeon R9 380 4G should be much (about 60%) faster with regards to texture filtering than the Radeon R9 M290X. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon R9 380 4G is a better choice, but not by far. (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 largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 amount of texture map elements (texels) that are processed per second. This 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 processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core 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 output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
