Samsung Illustrates the Innovations of the Exynos 9820 Chip

Samsung has listed the news of the Exynos 9820 chip that will be integrated into the Galaxy S10, highlighting the improvements compared to the previous Exynos 9810.


Samsung has mentioned more details about the processor of the Galaxy S10. According to the company, the chip of the Exynos 9 Series presented in November is said to usher in “a new era of mobile experiences.” Specifically, Samsung promises “intelligent processor performance, multi-gigabit Internet” and rich multimedia capabilities.

The built-in Neural Processing Unit (NPU), which performs AI tasks around seven times faster than its predecessor, is designed to allow the implementation of artificial intelligence anywhere, anytime. Samsung wants to use the new AI features to enhance personal assistants, augmented reality and the camera.

The computing powers

The computing power of the Exynos 9820 compares Samsung with that of a desktop system – at least in terms of user experience. To this end, the Korean company is combining two proprietary cores with two ARM Cortex A75 cores and four other Cortex A55 cores.


The Samsung cores are responsible for performance-hungry tasks. The Cortex-A75 cores, on the other hand, are designed to provide optimum performance while the Cortex-A55 cores are expected to become active in everyday tasks.

The increase in performance of its own cores compared to its predecessors is about 20 percent. Other benefits include an intelligent task scheduler that optimizes the performance balance between the three clusters (high performance, optimal performance, everyday tasks) to provide longer battery life.


The integrated LTE Advanced Pro modem supports LTE Cat. 20 and download speeds of up to 2 GBit/s. The reception performance Samsung wants to improve with a 4 × 4 MIMO antenna technology. In addition, Samsung at least indirectly confirmed a 5G version of the Galaxy S10, the Exynos 9820 should connect to the Exynos modem 5100, Samsung’s 5G mobile modem.

In addition to the CPU and modem, the system-on-a-chip also integrates a Mali G76 MP12 graphics unit. New execution units, graphics compression technologies, and extended API support are expected to deliver 40 percent more power while increasing energy efficiency by 35 percent.

Improvement in Camera and Video

The Exynos 9820 supports up to five camera systems, which can be extended by AI functions. “This means that when a user clicks the shutter button within the camera app, billions of arithmetic operations are performed by the enhanced Image Signal Processor to produce better focus, closer exposure and white balance, vivid colors and less noise, and take such amazing photos,” said Samsung.

The Exynos 9820 will also support 8K video recordings. Samsung wants to solve the problem of large amounts of data to be stored with the Multi-Format Codec (MFC), which in turn uses the HEVC codec with a color depth of 10-bit. It also means that there are 1024 different gradations for each primary color and thus a total of 1.07 billion color combinations are available.


Another component of the new flagship processor is the display subsystem. It will support HDR10+ with a 4K UHD resolution, which is probably true for the Galaxy S10. To improve security, the SoC also uses a digital fingerprint that provides a non-editable key for data encryption. The key, in turn, is also based on the physical characteristics of each chip.

Samsung manufactures the Exynos 9820 in an 8-nanometer FinFET process. It should consume 10 percent less power compared to the predecessor. It is possible, among other things, by lowering the operating voltage and reducing losses.

The Galaxy S10 will present Samsung on February 20, probably in three variations. They are said to differ in several details such as display and camera, but all use the same processor, namely the Exynos 9820. In some markets, including the United States, Samsung will probably rely on Qualcomm’s new top of the range Snapdragon 855.
