Compare any two graphics cards:
Radeon R7 250X vs Radeon R9 M385X
IntroThe Radeon R7 250X has clock speeds of 1000 MHz on the GPU, and 1125 MHz on the 1024 MB of GDDR5 RAM. It features 640 SPUs as well as 40 TAUs and 16 ROPs.Compare all that to the Radeon R9 M385X, which comes with a core clock speed of 1100 MHz and a GDDR5 memory speed of 1500 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically, the Radeon R9 M385X should be a lot faster than the Radeon R7 250X in general. (explain)
Texel RateThe Radeon R9 M385X should be quite a bit (more or less 54%) faster with regards to texture filtering than the Radeon R7 250X. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon R9 M385X is superior to the Radeon R7 250X, though 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 maximum amount of information (measured in megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to 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 ability to get to the maximum fill rate.
