Compare any two graphics cards:
Radeon HD 6970 vs Radeon R5 M255
IntroThe Radeon HD 6970 comes with a GPU core clock speed of 880 MHz, and the 2048 MB of GDDR5 RAM runs at 1375 MHz through a 256-bit bus. It also features 1536 SPUs, 96 Texture Address Units, and 32 ROPs.Compare those specifications to the Radeon R5 M255, which comes with a GPU core clock speed of 940 MHz, and 2048 MB of DDR3 RAM running at 1000 MHz through a 64-bit bus. It also is comprised of 320 Stream Processors, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon HD 6970 will be 1000% faster than the Radeon R5 M255 overall, because of its greater bandwidth. (explain)
Texel RateThe Radeon HD 6970 will be a lot (about 349%) more effective at texture filtering than the Radeon R5 M255. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 6970 is superior to the Radeon R5 M255, and very much so. (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 data (in units of megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
