Tencent’s in‑house Canghai V1 video encoding chip swept all metrics (SSIM, PSNR, VMAF) across 30–240fps at the MSU Hardware Video Encoding Competition, beating over 40 entries from AMD, Nvidia, Intel, and others. Compression ratios lead by >30% .

Launched in 2023, the Canghai V1 has been deployed across >100,000 units in Tencent Cloud and internal services (live streaming, 4K transcoding, cloud gaming), reducing CPU dependence while delivering high quality, low latency, and low cost.

The next‑gen Canghai V2 , already taped out, will enter mass production in H2 2026. It features a unified hardware architecture supporting both H.265 and H.266 . At the same visual quality, H.265 compression improves by >10% , H.266 by >30% , and single‑chip throughput doubles. V2 integrates a CPU, GPU, and CV unit with super‑resolution, denoise, and color enhancement algorithms.

ICgoodFind: Tencent’s Canghai V1 leads the world in compression efficiency; V2 doubles down on H.266 and cloud gaming, raising the bar for video infrastructure.
