Well I tried to look a bit more on it, and compare our board to others with the same SOC. So if the R16 is basically the A33 we are actually underclocking the R16 and we could obtain ~50% more horse power?

There you see that the maximum frequency is not even 1.2GHz, but 1.5GHz
Allwinner a33 datasheet manual#
The Allwinner R16 datasheet/User manual doesn’t specify what is the maximum clock frequency of the SOC, but if we go to the sunxi-linux wiki we see that the R16 is actually a rebranded version of the A33, and if you go to: So I thought that maybe something was wrong with it and tried to look more information. Everything is at your own risk.Ĭlockworkpi is advertised as “Allwinner R16-J Quad-core Cortex-A7 CPU although if you check your cpufreq-info info with the kernel that came with OS v.0.5 you will see that the maximum frequency is, in fact, 1.008GHz witch is ~20% less. First, I’m not responsible for anything if you want to try what I did.
