AAEON EMB-BT1: A Linux-Friendly, Mini-ITX, Atom "Bay Trail" Board
The Radeon HD 8210 graphics with the AMD E1-2100 Kabini APU were slightly faster than the Bay Trail HD Graphics with the Atom E3825. It was only a difference of 9 vs. 13 FPS but still significant when both integrated graphics processors were using their open-source drivers. Using the Haswell HD Graphics 4600 was many times faster and yielded playable frame-rates for this open-source game.
The Atom E3825 can even run Unigine's Sanctuary and Tropics tests, but obviously at very low speeds.
With Xonotic at high image quality settings the Atom E3825 performance was ahead of the E1-2100.
The Atom E3825 on the AAEON board also had a competitive showing against the AMD E1-2100 Kabini graphics with GpuTest.
Well, that's the quick look at the graphics performance should you really be concerned about the Bay Trail graphics capabilities on Ubuntu 14.04 with this hardware. On the following pages are the processor-focused tests.
