Huawei builds a 5G modem in Kirin 990 flagship processor

The latest Huawei Kirin 990 flagship chipset will include a version with an integrated 5G modem, as well as an increase in speed over its predecessor, the company announced on stage at IFA 2019 today. The 7-nm processor includes a modem that, according to Huawei, can offer a maximum download speed of 2.3 Gbps and a maximum download speed of 1.25 Gbps, alongside eight ARM Cortex processor cores.

Huawei believes that the use of a single chip should allow its phones to gain in energy efficiency compared to a separate processor and modem.

The company announced the new processor a few days after Samsung announced a 5G chipset, the Exynos 980. In the meantime, Qualcomm is not expected to market a combined processor and modem until next year. Chipmaker MediaTek also has its own 5G chipset, announced in May.

Like the Samsung Exynos chip, the 5G version of the Kirin 990 does not support mmWave 5G. The company said it chose to omit this technology because it is mainly used in the United States, where Huawei does not currently sell its devices. Instead, it will focus on the 5G variant below 6 GHz, which is more widely used in the rest of the world.

The Kirin 990 relies heavily on the design of Arm chips for its processor and GPU components. However, relations between Huawei and the British chip designer were upset earlier this year when the United States imposed sanctions on Chinese society. Shortly after the decision, BBC News reported that ARM asked its employees to sever ties with Huawei. The impact on Huawei's future internal processors is not yet clear.

Huawei has announced that the Kirin 990 will power the latest entry of the company's Mate series, which is expected to be announced on September 19.
