The config actually states for the SoC scaling max to be 1344000khz (1.3ghz) (the same as the SNESC/NESC) however it doesn’t reach that limit. The current clock scaling governor is set to ‘performance’ but is clocked at 1008000khz (1ghz).
As shown here (direct from the R16 Datasheet): The max rating for the Allwinner A33/A23/R16 is 1.5ghz quad core with a maximum of voltage of 1.5v.
The A33 is the same SoC as the Allwinner R16/A23, the same SoC used in the NESC/SNESC. The SoC is either a rebranded/clone Allwinner A33. This has been talked about online a lot since we posted about it, so just some clarifications and facts. Before we start, I assume you noticed our new kick ass project logo above. We are going to share any information and show a couple of bits that have taken place since the last update. Back due to popular demand, this is project update part 2 on our initial findings on the SEGA Mega Drive/Genesis mini.
