Huawei today announced its Kirin 990 5G system on a chip, which it calls the “world’s first flagship 5G SOC.” It made the announcement here in Berlin at its IFA keynote.
The SOC is produced on a 7nm FF+ EUV process and has 10.3 billion transistors on board. Huaweiclaims to have a board area 36 percent smaller than its competitors, Samsung and Qualcomm.

This will compete with the Samsung Exynos 980, which that company announced on Wednesday in a surprise drop. That chips is aimed at the mid-range, however, while Huawei is considering the Kirin 990 5G a flagship chip. Huawei is also announcing the Kirin 990, a slightly less powerful chip without 5G support.
Huawei suggests that the chip and receivers will use machine learning to ensure high data speeds. When you enter a weak 5G signal area, the modem will split uplink between 4G and 5G. Kirin 9905G will support both 5G non-standalone (NSA) and 5G standalone (SA) networks.
It claims that the chip will offer a downlink up to 2.3Gbps and uplink of up to 1.25Gbps. The chip supports four sub-6 antennae.
As for the image signal processor (ISP), Huawei is using its fifth-generation dual ISP, and it is claiming improvement in throughput, power efficiency, image and video noise reduction. It also uses block-matching and 3D filtering (BM3D) for what it says will result in DSLR-style noise reduction on its phones.
The GPU on the Kirin 990 5G is the 16-core Mali-G76; that’s up from 10 cores on the Kirin 980. Huawei claims that a smart cache will help with gaming, reducing GPU-to-memory bandwidth needs by 15% and reducing DDR power consumption by 12%.
The neural processing unit uses Huawei’s Da Vinci architecture and a new “Tiny Core” in combination, which Huawei claims makes it much more efficient. It said that 90% of CV neural networks are supported.
We haven’t yet heard when these new Kirin will be released, or which of Huawei’s devices they’ll wind up in. There’s also the question of course, of whether or not you’ll actually be able to buy any of Huawei’s phones or tablets in the US once they actually arrive with these new SoCs.
