must have been simply typing mistakes.
Not necessarily, some brands like to make out that they have the best, and when it is so difficult to find out the truth, why not not make some intentional typing mistakes?
That might mean that the "mistake" was made by the manufacturer, and the companies rebranding the dashcams just copied the mistake, since it is also hard for them to check, they tend to just trust the manufacturer.
It needs someone who actually talks to the relevant part of Novatek, like Viofo, to know what doesn't actually exist, it is hard enough for other people to find info on the Novatek chips that do exist!
Generally, it doesn't much matter, since recent Novatek SoCs have only really differed in their processing power, the number of processing cores, and maybe the number of video channel inputs. What matters is what the dashcam company can manage to make those SoCs do, and some brands get more out of the cheaper processors than others get out of the expensive ones. Some of the newer SoCs coming up might be worth taking note of, Novatek have been investing in new semiconductor technology, so the newer processors are likely to be significantly more power efficient, and at some point they will include an AV1 codec, but for now, I wouldn't worry about the processor number, it is the image sensor that matters, you want Sony Starvis 2 image sensors, plus a Novatek processor that can handle the Sony HDR properly. None of the non-Novatek processors can do that yet.
