Samsung launches Exynos 9820 with 2 Gbps LTE modem and dedicated NPU

Christmas has come early for Samsung fans as the Korean manufacturer released its latest Exynos 9820 chipset for smartphones. It is based on the 8 nm LPP (Low Power Plus) FinFET process and is an evolution from the 10 nm Exynos 9810. The SoC came with 2 Gbps LTE modem, Tri-cluster CPU and improved NPU.

Samsung implemented 4th-gen CPU with two custom cores for ultimate processing power, two Cortex-A75 cores for performance and a third cluster of four Cortex-A55 units for efficiency. The company said the new configuration has intelligent task scheduler to boost multi-core performance by 15% from the previous Exynos. The single-core results would be up to 20% and provide 40% power efficiency.

The LTE-Advanced Pro modem is another step towards 5G chipsets with 2 Gbps downlink speeds, but the company deterred from using the next-gen term in its press release. Technical specs included 8x CA and 316 Mbps uplink. Like its predecessor, the Exynos 9820 relies on 4×4 MIMO, 256-QMA and eLAA technology for blazing speeds.

On the GPU side the company put Mali-G76 cores which should deliver a 40% performance boost or 35% power savings, allowing longer usage of VR and AR applications. The NPU is a separate unit that would make any AI processes about seven times faster. In practice, it should help the camera to adjust the settings to the surrounding or objects in focus to provide better information.

Samsung said the chipset is expected to be in mass production by the end of this year, meaning it should be ready for the Galaxy S10 launch, typically taking place in Q1 2019.
