Revisiting FullHD X11 desktop performance of the Allwinner A10
Looking, in detail, into how the CPU and GPU contend for memory on the A10 -- and why some A10 machines (particularly with 16-bit memory) struggle with high resolutions. This is lovely stuff -- it's like talking about the Spectrum all over again!
