Compare any two graphics cards:
Radeon R5 M255 vs Radeon R5 M330
IntroThe Radeon R5 M255 uses a 28 nm design. AMD has set the core frequency at 940 MHz. The DDR3 RAM works at a speed of 1000 MHz on this particular card. It features 320 SPUs along with 20 Texture Address Units and 8 Rasterization Operator Units.Compare all that to the Radeon R5 M330, which has core speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon R5 M255 should theoretically perform just a bit faster than the Radeon R5 M330 in general. (explain)
Texel RateThe Radeon R5 M330 will be a small bit (approximately 10%) faster with regards to anisotropic filtering than the Radeon R5 M255. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon R5 M330 is the winner, not by a very large margin though. (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 max amount of data (in units of megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once 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 number is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video 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 that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few 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.
