Can not manufacture Kirin 990.
Smic cannot contract the 7nm Kirin 990 chip. Smic can do contract manufacturing for low-end Kirin chips, such as the 14nm process Kirin 710A is SMIC foundry. However, SMIC's 7nm process is currently unable to achieve commercial mass production stage, because the 7nm yield is not high, and when SMIC can achieve 7nm mass production is temporarily unpredictable. Moreover, SMIC's lithography machine actually uses the Dutch Asmer, and there are many obstacles to truly OEM Kirin 990 and other models of chips.
No, Kirin 990 will integrate 5G baseband chip Balong 5000, without external 5G chip can achieve 5G network, while supporting SA\/NSA two 5G networking modes, and support TDD\/FDD full band. Download rate 2.3Gbps, uplink peak rate 1.25Gbps; With the overlay of LTE, the download peak rate is 3.3Gbps and the uplink peak rate is 1.32Gbps.
