Compare any two graphics cards:
Radeon R5 M255 vs Radeon R9 270
IntroThe Radeon R5 M255 makes use of a 28 nm design. AMD has clocked the core speed at 940 MHz. The DDR3 memory is set to run at a frequency of 1000 MHz on this particular model. It features 320 SPUs along with 20 TAUs and 8 Rasterization Operator Units.Compare those specifications to the Radeon R9 270, which features a clock frequency of 900 MHz and a GDDR5 memory speed of 1400 MHz. It also features a 256-bit bus, and uses a 28 nm design. It is made up of 1280 SPUs, 80 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon R9 270 should be a lot faster than the Radeon R5 M255 overall. (explain)
Texel RateThe Radeon R9 270 will be quite a bit (approximately 283%) more effective at texture filtering than the Radeon R5 M255. (explain)
Pixel RateThe Radeon R9 270 is much (more or less 283%) faster with regards to AA than the Radeon R5 M255, and also will be capable of handling higher resolutions better. (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 (counted in megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
