Recent wrap in numbering of Exynos chips > might bring confusion... Judging by vendor's sources it is quite confusing. It looks mostly like Exynos3830 but in few other cases it uses Exynos9 compatibles (Exynos9, Exynos9820). Only in few places there is Exynos850. Marketing department made it so confusing... The revision embedded in SoC would be very interesting. Anyway, judging by current versioning, there is a risk Samsung will come with a new chipset name conflicting with existing ones. It already overflowed. It's even worse with a thingy called "Exynos9 auto" which hides numbering even more. Best regards, Krzysztof
