Leaks suggest upcoming Samsung Exynos 9830 SoC will only use ARM Cortex cores
Samsung’s Exynos 9820 SoC was supposed to match the performance of Qualcomm’s Snapdragon 855, but the 8 nm tech used by the Koeran giant fell short in comparison to the 7 nm U.S. SoC. Meanwhile, Samsung managed to complete its own 7 nm EUV nodes and released the Exynos 9825 SoC, a minor upgrade over the 9820 model that is considered as an intermediary step between the original 9820 and the next gen SoC that will be launched in February 2020.
Since Samsung did not make any architectural changes for the Exynos 9825 chip, its performance is mostly in line with the Snapdragon 855, yet it cannot really compete with the Snapdragon 855+. However, Samsung intends to make some major changes for the next gen flagship SoC, if we are to believe the latest report coming from renowned leaker Ice_Universe (80% accuracy cited this time).
Instead of using its proprietary Mongoose M4 cores for the high-end CPU core cluster, Ice_Universe claims that the upcoming flagship SoC provisionally named Exynos 9830 will exclusively integrate ARM Cortex cores. So, unlike the current architecture that combines two Mongoose M4 cores with two ARM Cortex high-speed cores, the next gen Exynos 9830 is getting a 4-core ARM Cortex-A77 cluster, plus a high-efficiency cluster that includes four ARM Cortex-A55 cores.
It is yet unclear why Samsung would choose to drop its own technology. The Mongoose cores were derived from ARM’s designs anyway, so Samsung might be thinking that it is not worth it anymore to further tune an already stellar design.
