Huawei’s CEO is saying that the Kirin 990 chip is too strong, so it doesn’t need ARM’s latest CPU core.

Tram Ho

A few days ago, Huawei launched its highest-end Kirin 990 processor. Kirin 990 is designed by HiSilicon and manufactured by TSMC based on 7nm process, containing 10.3 billion transistors and integrated 5G modem chip. The processor will be equipped with upcoming Mate 30 and Mate 30 Pro smartphones.

Kirin 990 has 8 CPU cores, including 4 high-performance Cortex-A76 cores (2 cores clocked at 2.86 GHz and 2 cores clocked at 2.34 GHz) and 4 power-efficient Cortex-A55 cores with 1.9 GHz .

One question many people ask is why Huawei doesn’t use the latest and most powerful Cortex-A77 cores? According to ARM’s statement, the Cortex-A77 cores are up to 20% stronger than the Cortex-A76.

Huawei Consumer Product Group CEO Richard Yu gave some interesting answers. And these causes have nothing to do with the U.S. ban on Huawei.

The executive said that the performance of the Kirin 990 is “beyond user demand,” so using a more powerful CPU core in exchange for shorter battery life is not necessary.

Prior to that, however, ARM had said that the Cortex-A77 cores were more powerful but didn’t consume much more power. Huawei’s testing and claims are completely at odds with ARM. So one of the two companies is definitely not telling the truth.

Yu added that Huawei will use the Cortex-A77 CPU core after the manufacturing process shifts to 5nm. The smaller the size, the larger the number of transistors on the chip. And the more transistors the higher the power-saving capability.

Huawei is blacklisted by the United States and restricts cooperation, supply of components or licensing software. And although ARM Holdings is based in the UK, it still uses US technologies. Therefore ARM is also subject to this ban.

Fortunately, Huawei signed a licensing contract with ARM before the US ban was enacted. Therefore, Huawei can still use existing Cortex CPU cores to design its chips. But most likely in the future, when the license agreement ends, ARM will also have to comply with the ban and stop licensing CPU core designs for Huawei.
