A few days ago, Samsung unveiled its newest high-end automobile processor, the Exynos Auto V920. It succeeds the Exynos Auto V9 that was launched a few years ago and has been used in Audi cars. The new chip brings newer CPU cores and an extremely powerful Xclipse GPU based on the AMD Radeon RDNA2 architecture.
Exynos Auto V920 is 70% faster than the previous generation Exynos Auto chip
The Exynos Auto V920 is Samsung's latest processor for cars and other automobiles. It is a 5nm chip made by Samsung Foundry, and it features a 10-core Cortex-A78EA CPU with two quad-core clusters and one dual-core cluster. The chip distributes the workload between these clusters, depending on the requirement. The South Korean firm says that its performance is 70% faster than the previous-generation Exynos Auto chip (Exynos Auto V9). It also features the Xclipse GPU that is based on AMD's RDNA2 architecture, which is also used in the Exynos 2200 smartphone chip.
Previous Exynos Auto chips used ARM's stock Mali GPU cores. The new GPU can drive up to six high-resolution screens (3x 5K displays + 3x Dual Full HD displays), including the DIC (Digital Instrument Cluster) and the main infotainment screen on the front and four additional screens for rear passengers.
There is a dual-core NPU that offers up to 23.1 TOPS of AI (Artificial Intelligence) and ML (Machine Learning) performance. It can monitor surroundings by recognizing objects in real time from the camera feed to offer smart and autonomous driving features. The chip can support up to 12 camera sensors simultaneously. The ISP supports 144db HDR feeds with the on-die merging of four exposure levels, so assisted and autonomous driving performance doesn't face issues even in bad lighting conditions.
Other features of the Exynos Auto V920 include an integrated DSP (Digital Signal Processor) for audio processing. It has three new-generation HiFi 5 cores for immersive audio and clear voice calls. The embedded safety island on the Exynos Auto V920 has ASIL-B (Automotive Safety Integrity Level B) certification for enhanced security. The chip is compatible with LPDDR5 DRAM, UFS 3.1 storage, and two 10Gbps 2x USXGMII/SGMII/RGMII ethernet connections.
This new Exynos Auto chip will be used to power the infotainment system in future Hyundai cars that are slated to be released in 2025.
