[Galaxy Tab S Q&A, Help & Troubleshooting] BarryH_GEG:
If it were purely TW related, wouldn't all the high-end tablets that preceded the S' also behave the same way? Meaning pronounced performance differences between Exynos and S-800? Hardware wise the CPU, GPU, radios (Wi-Fi, 3G, 4G) and pixel count have been the same since last year. If the software Samsung coded for Exynos and S-800 didn't create SoC-specific performance issues with Note's and Pro's, the latter using M-UX just like the S', what's unique about the S'? And the N3 uses the same SoC combo and doesn't have Exynos-specific performance issues.

Samsung hasn't had SoC specific problems (that I'm aware of) with other devices using multiple SoC's. The only h/w differences between the S' and earlier tablets is the substitution of AMOLED for LCD and a finger print reader. We all know AMOLED sucks on whites (on any SoC) so perhaps whatever performance throttling being applied to extract decent battery life is more aggressive on Exynos? But, again, the N3 is AMOLED and the Exynos and S-800 get almost identical battery life. And the finger print reader didn't seem to affect Exynos vs Snapdragon on the SGS5.

The S is an important tablet for Samsung and SLI builds Exynos so it would seem odd that for the first time (that I'm aware of) there were performance issues biased toward one SoC vs. another. Everything discussed as "annoyances" is subjective. In every Samsung forum where a single device uses multiple SoCs there are people swearing both are slower/faster than the other and get better/worse battery life. That's the danger of subjectivity.
