Is there a clear winner in this ranking ? Broadcom have released some documentation on the RPi's GPU while AllWinner have used 3rd party IP that they can't document ({Mali,PowerVR} and Ethernet).
- makomk 11y agoArguably there is - you can boot these AllWinner chips using entirely open source code, whereas you need a binary blob to boot the Pi at all and the license agreement forbids you from using it on non-Pi Broadcom hardware. Also, the USB interface on the Pi is third party IP from Synopsis that - last time I checked - they can't document, it's incredibly buggy, and Ethernet goes through it too. (Whereas the AllWinner USB host interface is standard EHCI, just like an ordinary PC.)
- userbinator 11y agoAllWinner's Ethernet peripheral is also directly connected to the CPU bus, which makes for a huge difference: http://hardware-libre.fr/2014/06/raspberry-vs-banana-hardware-duel/ http://hardware-libre.fr/2014/06/raspberry-vs-banana-hardwar... (Look at the network benchmark in particular.)
