It was first reported last year that Samsung is working on two new high-end Exynos chipsets one of which features an AMD GPU – the Exynos 9855 and Exynos 9925. GalaxyClub reports that the Exynos 9855 has the codename Whitechapel which has already been associated with Tensor. Google’s Tensor SoC is thus the unreleased Exynos 9855.
Nope just the 4a 5G. The screen should be better since it's 90hz I think and has wireless charging as well. Rest of the specs are the same. Personally I wouldn't buy at that price since the camera hardware is very old. Software optimization can only get you so far.
