Compare any two graphics cards:
Radeon R5 M255 vs Radeon R9 M275X
IntroThe Radeon R5 M255 makes use of a 28 nm design. AMD has set the core frequency at 940 MHz. The DDR3 memory works at a frequency of 1000 MHz on this specific card. It features 320 SPUs along with 20 Texture Address Units and 8 ROPs.Compare all of that to the Radeon R9 M275X, which features a clock speed of 900 MHz and a GDDR5 memory frequency of 1125 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon R9 M275X should in theory perform quite a bit faster than the Radeon R5 M255 overall. (explain)
Texel RateThe Radeon R9 M275X is quite a bit (more or less 91%) better at anisotropic filtering than the Radeon R5 M255. (explain)
Pixel RateThe Radeon R9 M275X should be a lot (approximately 91%) better at full screen anti-aliasing than the Radeon R5 M255, and also will be able to handle higher screen resolutions without losing too much performance. (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 (measured in megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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 - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
