Forget 90Hz, Samsung Exynos 990 processor will power 120Hz display’s in smartphones

At the Samsung Tech Day 2019, the South Korean giant announced two new silicon chips that are designed particularly to power future mobile devices that will in-depth use video and artificial intelligence (AI) applications as well as 5G communications.

The two chips — Exynos 990 which is a premium mobile processor and the ultra-fast next-generation 5G Exynos Modem 5123 are based on the advanced 7-nanometer (nm) process technology. Samsung has used extreme ultra-violet (EUV) in order to provide the seamless performance and to accelerate product development options for OEMs.

The Exynos 990 supports 120Hz refresh-rate display driver which will make gaming a much more seamless and lively by reducing screen tearing and enabling smoother animations even on devices with multiple displays, such as foldable phones.

With the Exynos 990, Samsung says that new levels of mobile gaming and other graphics-intensive operations could be achieved thanks to the inclusion of an embedded Arm Mali-G77 GPU, which is the first premium GPU based on the new Valhall architecture. This architecture improves graphic performance or power efficiency by up to 20 percent, which is in addition to the overall 20 percent performance boost that comes from the use of flexible tri-cluster CPU structure – consisting of two powerful custom cores, two high-performance Cortex-A76 cores, and four power-efficient Cortex-A55 cores.

The Exynos 990 uses on-device AI with a top-class dual-core neural processing unit (NPU) and improved digital signal processor (DSP) that can perform over ten-trillion operations (TOPs) per second. The NPU further enables localized AI in a smartphone allowing data to be processed directly on-device, instead of going through a network and a server, for added efficiency and security. This on-device AI can further boost the efficiency of AI features such as facial recognition and scene detection for richer mobile experiences.

Samsung developed the 5G Exynos Modem 5123, one of the first 5G modem chips manufactured using a 7nm EUV process to address the next-generation mobile connectivity needs. From 5G’s sub-6GHz and mmWave spectrums to 2G GSM/CDMA, 3G WCDMA, TD-SCDMA, HSPA, and 4G LTE, with outstanding downlink speed across the board, the modem supports virtually all networks,

In 5G, the modem supports up to 8-carrier aggregation (8CA) delivering a maximum downlink speed of up to 5.1-gigabits per second (Gbps) in sub-6-gigahertz (GHz) and 7.35Gbps in mmWave, or up to 3.0Gbps in 4G networks by supporting higher-order 1024 Quadrature Amplitude Modulation (QAM).

According to Samsung, the Exynos 990 complements these modem speeds and supports LPDDR5 data rates of up to 5,500 megabits per second (Mb/s). Both the chips are said to begin mass production by the end of this year.
