Radeon HD 8180 is an integrated graphics card on some of the Kabini APUs.
It is based on the Graphics Core Next Architecture and shares the main system memory of up to 533MHz, on a 128-bit memory interface, whereas the memory bandwidth and performance will depend heavily on the laptop configuration.
The codenamed Kalindi LP Core offers 128 Shader Processing Units, 8 TMUs and 4 ROPs and comes optimized for low power consumption.
Even assuming the best combination possible, expect its performance to be slower than an Intel HD 2000 and thus the card is hardly suited for any gaming. Its biggest advantage is its ridiculously lower power consumption.
