Last week we published our Galaxy S9 and S9+ review, and the biggest story (besides the device) was the difference between the processors used inside the two variants: the Snapdragon 845 SoC and Exynos 9810 SoC. Based on earlier announcements, we had large expectations from the Exynos 9810 as it promised to be the first “very large core” Android SoC. However, our initial testing put a lot of questions on the table. Unfortunately the synthetic performance of the Exynos 9810 did not translate well at all into real life performance. As part of the testing, I had discovered that the device’s scheduler and DVFS (dynamic voltage-frequency scaling) configurations were atrociously tuned.

For the full review I had opted not to go modify the device, as that initial review was aimed as a consumer oriented article, and it would serve little purpose to readers (that and time constraints). Still I promised I would follow up in the coming weeks and this is the first part of what’s hopefully a series where I try to extract as much as possible out of the Exynos 9810 and alleviate its driver situation.
