Samsung announces Exynos 9820 with dedicated AI core and three CPU clusters
Samsung might use Qualcomm chips in most of its North American phones, but everyone else gets the company's custom Exynos chips. The last-gen Exynos 9810 had some issues, but Samsung aims to rectify that with a substantial redesign of the new 9820. It's still using custom CPU cores alongside low-power ARM reference designs, but there's a third cluster of high-power ARM cores as well.
Last year's 9810 had a fairly typical arrangement of four M3 custom CPU cores with four Cortex-A55 cores. This year, the 9820 has two fourth-gen custom CPU cores (probably M4) with four Cortex-A55 low-power cores. You also get two Cortex-A75 reference cores as the third CPU cluster. Samsung says the new design is 20% faster at single-threaded tasks and has 40% higher power efficiency. The tri-cluster design is allegedly 15% faster at multi-threaded tasks. A new Mali G76MP12 GPU is around 40% faster and 35% more efficient than last year's chip.
The Exynos 9820 is also the first Samsung SoC to include a dedicated AI processing core. That should allow future Samsung devices to run AI processes locally rather than offloading to a server. The SoC includes Samsung's latest LTE modem, too. It's capable of 2Gbps with 8x carrier aggregation, 4x4 MIMO, and 256 QAM.
Samsung says the Exynos 9820 will go into full-scale production by the end of the year. It's likely you'll see this chip in the international Galaxy S10 in early 2019.
