Compare any two graphics cards:
Radeon R9 M270X vs Radeon R9 M375
IntroThe Radeon R9 M270X has a GPU core clock speed of 725 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1125 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.Compare all that to the Radeon R9 M375, which features GPU clock speed of 1015 MHz, and 4096 MB of DDR3 RAM running at 1100 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon R9 M270X is 105% faster than the Radeon R9 M375 in general, because of its higher data rate. (explain)
Texel RateThe Radeon R9 M375 will be much (more or less 40%) faster with regards to anisotropic filtering than the Radeon R9 M270X. (explain)
Pixel RateThe Radeon R9 M375 will be quite a bit (more or less 40%) better at anti-aliasing than the Radeon R9 M270X, and should be able to handle higher resolutions more effectively. (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 data (in units of megabytes per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels the graphics 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 ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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 get to the maximum fill rate.
