Loongson Technology is moving forward with the rollout of its generation 5 desktop silicon and companion chipsets. Company chairman Hu Weiwu confirmed during an earnings briefing that the 3B6600 desktop processor finished tape out delivery and will return initial silicon in Q4 of 2026. The incoming processor marks the debut of the 6600 series architecture for domestic consumer computers.
According to reports from the STAR Market Daily, Loongson sent the 3B6600 processor for fabrication in Q2 of 2026. The companion 7A3000 bridge chip followed with tape out delivery in Q3 of 2026, with factory test samples scheduled to arrive in Q4 of 2026. Loongson also plans to finalize design work on a low cost 3A6600 desktop processor before the end of Q4 in 2026.
Independent domestic fabrication requirements dictate the production timeline for the new chips. Earlier details published by IT Home show the 3B6600 finished its initial design phase before shipment to foundry partners. Hu explained that relying on independent domestic fabrication lines requires longer testing cycles to tune the silicon layout. The 6600 family serves as the core computing platform for Loongson as the company expands its desktop processing line.
