Compare any two graphics cards:
Radeon R5 M230 vs Radeon R5 M255
IntroThe Radeon R5 M230 comes with a clock frequency of 780 MHz and a DDR3 memory frequency of 1000 MHz. It also features a 64-bit memory bus, and uses a 28 nm design. It features 320 SPUs, 20 TAUs, and 4 Raster Operation Units.Compare all that to the Radeon R5 M255, which features GPU clock speed of 940 MHz, and 2048 MB of DDR3 RAM running at 1000 MHz through a 64-bit bus. It also is made up of 320 SPUs, 20 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthBoth cards have the exact same bandwidth, so theoretically they should have identical performance. (explain)
Texel RateThe Radeon R5 M255 should be much (about 21%) more effective at texture filtering than the Radeon R5 M230. (explain)
Pixel RateThe Radeon R5 M255 will be a lot (about 141%) more effective at full screen anti-aliasing than the Radeon R5 M230, and also will be 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 maximum amount of information (measured in megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 applied per second. This is worked out 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 video 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 could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output 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 max fill rate.
