At the ongoing Samsung Tech Days, Samsung announced two silicon products for future mobile devices. Focused on Video processing and artificial intelligence (AI) applications, the Exynos 990 premium mobile processor is based on the 7-nanometer(nm) process, along with the 5G Exynos Modem 5123.
The Exynos 990 features Arm Mali-G77 GPU for graphics-intensive usage. It is the first GPU based on the new Valhall architecture, which improves graphic performance or power efficiency by up to 20 percent. This comes in addition to an overall 20-percent performance boost from an extremely powerful and flexible tri-cluster CPU structure that consists of two powerful custom cores, two high-performance Cortex-A76 cores and four power-efficient Cortex-A55 cores.
The Exynos 990 also enhances on-device AI, thanks to its dual-core neural processing unit (NPU) and improved digital signal processor (DSP) that can perform over ten-trillion operations (TOPs) per second.
The NPU enables localized AI in a smartphone or other mobile platform, allowing data to be processed on-device, rather than going through a network and a server, for added efficiency and security. This can also help enhance AI features such as facial recognition and scene detection for richer mobile experiences.
The 5G Exynos Modem 5123 supports virtually all networks, 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. In 5G, with up to 8-carrier aggregation (8CA), the modem delivers 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).
The Exynos 990 complements these modem speeds with a very wide memory bandwidth that supports LPDDR5 data rates of up to 5,500 megabits per second (Mb/s). The processor also features a 120Hz refresh-rate display driver, which makes games come alive by reducing screen tearing and enabling smoother animations even on devices with multiple displays, such as foldable phones. Also on board is an advanced image signal processor (ISP) that supports up to six individual image sensors with concurrent processing of three; this enables pro-grade photography, with resolution up to 108-megapixels.
The Exynos 990 and Exynos Modem 5123 are expected to begin mass production by the end of this year.
