Compare any two graphics cards:
Radeon R9 380X vs Radeon R9 M275X
IntroThe Radeon R9 380X uses a 28 nm design. AMD has set the core speed at 970 MHz. The GDDR5 RAM is set to run at a speed of 1425 MHz on this card. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.Compare all of that to the Radeon R9 M275X, which makes use of a 28 nm design. AMD has set the core speed at 900 MHz. The GDDR5 memory is set to run at a speed of 1125 MHz on this model. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon R9 380X should in theory be much superior to the Radeon R9 M275X in general. (explain)
Texel RateThe Radeon R9 380X should be much (more or less 245%) better at anisotropic filtering than the Radeon R9 M275X. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon R9 380X is superior to the Radeon R9 M275X, by a large margin. (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 megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
