Word traveled down the grape vine that Samsung is in talks with both AMD and NVIDIA to see what its options are to get better graphics in its phones. At the moment, Samsung uses ARM's Mali GPU in its Exynos chipsets, but according to SamMobile the company may license NVIDIA or AMD technology.
Currently, Samsung is using ARM’s Mali series of GPUs in its Exynos chipsets. According to information that we’ve received, Samsung is in talks with both AMD and Nvidia to license their GPU technologies. As of now, Nvidia seems to have an upper hand due to its superior Pascal architecture. However, that doesn’t mean AMD could be ruled out, especially since Sony just announced its PS4 Pro gaming console with 4K gaming that uses AMD’s Polaris architecture.
