Rob Clark, maker of the open source GPU driver Freedreno shows off his latest Freedreno open source GPU working on an upcoming Qualcomm Snapdragon 820 based Dragonboard 820c development board, one that is going to use an expanded 96Boards specification to add PCI-E and Gigabit Ethernet ports among other things to the development board. This Freedreno and 820 board provides a significant jump in performance for the GPU, possibly 4x to 5x between the Adreno 306 in a Dragonboard 410c and the Adreno 530 in a Snapdragon 820 based board. The availability of the Freedreno open source GPU driver on Qualcomm based development boards means that these development boards can run all sorts of Linux distributions, including Debian, not just Android.
