Compare any two graphics cards:
Radeon HD 5550 vs Radeon R5 M255
IntroThe Radeon HD 5550 makes use of a 40 nm design. AMD has set the core speed at 550 MHz. The DDR2 memory is set to run at a speed of 400 MHz on this particular card. It features 320(64x5) SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.Compare that to the Radeon R5 M255, which comes with core speeds of 940 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs along with 20 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon R5 M255 will be 25% quicker than the Radeon HD 5550 overall, due to its greater bandwidth. (explain)
Texel RateThe Radeon R5 M255 is much (more or less 114%) faster with regards to AF than the Radeon HD 5550. (explain)
Pixel RateThe Radeon R5 M255 is a lot (approximately 71%) faster with regards to FSAA than the Radeon HD 5550, and also will be able to handle higher 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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, the result 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 high 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 clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
