Godson put forward dragon chain technology for the first time: nVLink and CXL for 3C6000 server chip.

Thank CTOnews.com netizens Cainiao N for the clue delivery! CTOnews.com November 6 news, in today's Godson third quarter 2023 results presentation meeting, Godson Zhongke for the first time announced the "dragon chain technology."

According to reports, Godson 3C6000 server chip has basically completed the design, equipped with 16 cores and 32 threads, through dragon chain technology (Loongson Coherenent Link) to achieve inter-chip interconnection, the recent delivery of taping.

CTOnews.com learned from the performance presentation that dragon chain technology can achieve the connection of Chiplet (small chip, core) by aligning nVLink and CXL. Loongxin Zhongke said that compared with the inter-chip interconnection protocol of 3A5000, the inter-chip interconnection delay is reduced exponentially, the bandwidth is increased several times, and the performance of multi-chip cooperation is greatly improved. Dragon chain has a lower speed than nvlink (currently each rate is 16Gbps, the next step will be increased to 32Gbps), but the efficiency is already good.

Hu Weiwu, chairman and general manager of Loongxin, said: "compared with 3C5000 general processing performance, IO performance and inter-chip interconnection performance, 3C6000 has greatly improved, and the cost has been reduced. I think it should be competitive in a specific open market."
