The launch of the Exynos 2200 will be a major event in smartphone graphics. The industry tends to lose GPU vendors, not new vendors. The chipset’s GPU is based on AMD’s RDNA2 architecture used in APUs, graphics cards, and (modified) PlayStation 5 and Xbox One series consoles.
Peak performance is improved by 31% to 34%, and sustained performance is improved by 17% to 20%. Please note that these numbers are based on pre-release hardware and software and may vary depending on the final product.
The bigger question is how the architecture handles the migration of mobile disk sets to limited TDP. Leakster shared a number that shows better performance than the current Exynos 2100.

It’s hard to say how the Exynos 2200 GPU will be compared to Adreno in the new Snapdragon 898. Exynos is expected to benefit significantly over the 3DMark WildLife Outgoing Snapdragon 888, but there is no reliable data with the 888. .898 performance.
AMD GPUs offer some unique features such as beam detection, so raw performance doesn’t tell the whole story.
Beam detection is now standard in high-end computer and console games, giving game developers a lot of experience with beam detection. Recently Published Via GSMARENA
