On Thursday morning in South Korea, Samsung has just announced its flagship chipset for 2020. The Exynos 990 chipset gets a 20% performance hike from its use of a tri-cluster CPU setup that includes two of Sammy’s custom cores, two ARM Cortex-A76 high-performance cores, and four Cortex-A55 efficiency cores. The chip will also feature ARM’s Mali-G77 graphics processor; Samsung says that this is the first premium GPU based on the new Valhall architecture and it provides a 20% improvement in graphics performance or power efficiency. That should warm the cockles of mobile game players’ hearts.
On-device AI is handled through a dual-core neural processing unit (NPU). By allowing AI functions to be processed on-device instead of through a network and a server, these operations can be done faster and in a more secure fashion. It also can improve an AI-based facial recognition system and enhance scene detection employed by cameras; the latter automatically use certain settings in order to produce the best possible picture depending on the subject matter and the location. The manufacturer says, “Samsung’s Exynos 990 and Exynos Modem 5123 are perfectly adapted for high-volume 5G and AI applications, and are designed to help the world’s most ambitious enterprises, large and small, achieve their goals of bringing new capabilities to their markets.”
The aforementioned 5G Exynos Modem 5123 is one of the first modem chips made using the 7nm EUV process and supports both sub-6GHz and mmWave airwaves. The chip also will support 2G GSM/CDMA, 3G WCDMA, TD-SCDMA, HSPA, and 4G LTE. In 5G, with 8 carrier aggregation, the chip will handle download speeds up to 5.1Gbps on sub-6GHz and 7.35Mbps on mmWave networks. It also can deliver 3.06Gbps speed on 4G using 1024 QAM digital modulation. Considering that the maximum real-world download speed achieved on a 5G network is 3.67Gbps achieved by Huawei and its Swiss partner Sunrise, it would seem that Samsung’s 5G modem can handle all sorts of 5G traffic. Carrier aggregation is the combination of two or more carriers to form one larger data channel. This provides more room to handle large capacity data traffic, which in turn allows data to travel at faster data speeds.
The Exynos 990 chipset supports LPDDR5 data rates at 5,500 Mbps and can also help drive a 120Hz display refresh rate leading to very smooth scrolling and video game animation. The image signal processor (ISP) that comes with the SoC supports up to six individual image sensors with up to three processing at the same time. The ISP will handle images produced by cameras with a resolution as high as 108MP. Not coincidentally, Samsung announced that it had developed a 108MP camera sensor back in August.
