The DragonHawk One adopts a multicore heterogeneous architecture, with 8 CPU cores realizing 90K DMIPS of computing power, a 14 core GPU with 900GFLOPS computing power, and 8 TOPS NPU computing power.

In order to support a robust perception system and infotainment experience onboard, the chip’s ISP has a 1.6Gpixel/s processing power, allowing 360° view, parking, ADAS, and DMS functions.

The DragonHawk One adopts a 6400MT/s LPDDR5 memory channel, offering 51.2GB/s memory bandwidth to match its performance. The SoC satisfies various infotainment, image, and AI processing needs. According to the company, this is the first time for a smart cockpit SoC to use LPDDR5 memory commercially.

The DragonHawk One has already received orders for several vehicle models. It is expected to start mass-production in the third quarter of 2022 and be deployed onto the said vehicles by the end of 2022. The first vehicle to be powered by the DragonHawk One will be a Geely model.

The company added, by 2023, there will be at least two or three automakers choosing its DragonHawk One solution.

Moreover, SiEngine is currently developing the DragonHawk Two SoC dedicated to autonomous driving applications, which can be expected in 2024. In 2026, the company’s onboard CPU dubbed DragonHawk Three will also debut.
