The Exynos 9825 SoC is built on a 7nm manufacturing process. This is an upgrade over the Exynos 9820 which was built on an 8nm process. It also comes with a faster Mali-G76 MP12 GPU.
The Exynos 9825 chipset is the first in the industry with the EUV processing technology. Its predecessor, the Exynos 9820, was built on the 8nm LPP process.
According to Samsung, the new chipset comes with improved graphics performance and gaming experience. It is also more efficient in power consumption. This means that Samsung most likely focused more on efficiency improvement than benchmark numbers.
The Exynos 9825 has two M4 Cheetah cores, two Cortex-A75, and four Cortex-A55 units. It comes with the Shannon 5000 LTE modem, having Cat.20 downlink and Cat.13 uplink.
However, one can only achieve 5G connectivity when the chip is paired with the Exynos Modem 5100. We expect it to come in the Galaxy Note 10+ 5G.
