Vivo Releases New Imaging Chip, Will Adapt MediaTek’s Dimensity 9200 Chip
Chinese smartphone maker vivo on November 10 released the second generation of its self-developed V2 imaging chip, and introduced in-depth cooperation with MediaTek involving the use of its Dimensity 9200 chip.
Since 2021, vivo has launched two self-developed chips, the V1 and V1+. The new V2 adopts an AI-ISP architecture, bringing about overall improvements in the on-chip memory unit, AI computing unit and image processing unit.
Vivo proposed frame info tunneling (FIT) technology to establish a new high-speed communication mechanism between the V2 chip and Mediatek’s Dimensity 9200 chip, enabling them with completely different architectures and instruction sets to complete interconnected data and computing power within 0.01 seconds.
Thanks to vivo’s self-developed AI deep learning accelerator and large-capacity static random access memory (SRAM), the V2 chip greatly improves the capacity and computing speed of on-chip cache. Compared with traditional NPU, SRAM’s data throughput power consumption can be reduced by 99.2% at most.
At the meeting, vivo also brought forward advanced self-developed imaging algorithms, such as telephoto images, motion capture and dark light motion capture. With V2 chip’s algorithm and the blessing of new HDR, NR and ProMEMC, vivo’s mobile image technology has been pushed to a new level.
While developing its own chips, vivo also jointly tuned the SoC platform for mobile phones with MediaTek. Just on November 8, MediaTek released Dimensity 9200, which is the first SoC based on TSMC’s second-generation 4nm process technology. Vivo announced that it will soon release the first model adapting this chip.

In order to give full play to its hardware capabilities, vivo started considering the product requirements while designing chips to realize balance between performance and power consumption in actual use. Vivo and MediaTek cooperated deeply to develop five functions, including multi-cycle queue, adaptive image quality mode for Honor of Kings, eye protection, APU framework integration and AI airport mode.
According to vivo’s product manager, Han Boxiao, the firm’s first model to adapt the Dimensity 9200, which was rumored to be the X90, has a score of 1.28 million on AnTuTu, which is slightly higher than Mediatek’s official statement of 1.26 million.
“Vivo started its own research very early, and it took five to six years to launch V1, V1 + and today’s V2,” Huang Tao, vivo’s vice president of products, said at a press conference. “Nowadays, we combine independent R&D and cooperation with partners to bring consumers a better experience.”
