Compare any two graphics cards:
Radeon R5 M255 vs Radeon R9 285
IntroThe Radeon R5 M255 features core clock speeds of 940 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 320 SPUs as well as 20 Texture Address Units and 8 Rasterization Operator Units.Compare those specifications to the Radeon R9 285, which has a clock frequency of 918 MHz and a GDDR5 memory frequency of 1375 MHz. It also features a 256-bit bus, and uses a 28 nm design. It features 1792 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon R9 285 will be 1000% quicker than the Radeon R5 M255 in general, because of its higher data rate. (explain)
Texel RateThe Radeon R9 285 will be much (more or less 447%) better at AF than the Radeon R5 M255. (explain)
Pixel RateThe Radeon R9 285 is a lot (about 291%) more effective at AA than the Radeon R5 M255, and also capable of handling higher screen resolutions without slowing down too much. (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 (in units of MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
