As the first brother of domestic chips, Huawei Haith has many chips under its banner, such as Kirin, Kunpeng, Shengteng, Tiangang, Hongwan, Lingxiao and so on, but the most famous of them must be Kirin.
From the launch of the first K3 in 2009 to the launch of Kirin 9000 in 2020, Kirin chips have become the symbol of Huawei Haith, which also represents the highest level of domestic chips.
Huawei Kirin chip family, another new member, Kirin 990A is here, stock enough for 2 years
The newest addition to the Kirin family is the Kirin 990A.
The newest addition to Huawei’s Kirin chip family is the Kirin 990A, a chip that has never existed before and is used in cars. And Huawei said that Kirin 990A chip, at least enough to use 2 years, the inventory is still very adequate.

Kirin 990A, using the ARM architecture, its core design is 4 cores Tarzan V120 (small) + 4 cores based on ARM V7A series Vortex A55.
And the GPU part is using Mary G76, in addition Huawei also added Da Vinci architecture AI cores, respectively 2 D110 + 1 D100 size core.
From the naming, this chip is based on Kirin 990 chip to modify the build. However, we should note that this is a car chip, that is, a chip for the car computer (not autopilot), and theoretically not a car-grade chip, and of course it will be very different from a normal cell phone chip.

As for what performance is achieved, there is no specific test data, you can refer to is Qualcomm. Qualcomm’s current mass-produced high-end car chip is Qualcomm SA8155P, 8-core architecture, using a 7nm process.
Qualcomm this chip is based on Qualcomm Snapdragon 855 modified, with 1 super core main frequency 2.4GHZ, 3 large core main frequency 2.1GHZ, 4 low-power core main frequency 1.8GHZ, in performance than Qualcomm 855 slightly lower than about 15-20%.
Qualcomm has also released a 5nm car chip this year, but there is not much car use, the car with a 5nm car chip may have to be on the road next year, the mainstream of Qualcomm car chip or this one SA8155P.

So based on Kirin 990 compared to Kirin 990A, and then look at Qualcomm 855 and Qualcomm SA8155P, we can assume that Kirin 990A, should be about the same level as Qualcomm SA8155P, should also be 7nm process, performance may also be a little lower than Kirin 990.
Why can be enough for two years, because the car chip is very durable, a car is also a chip, car shipments are so small, unlike cell phones, may not sell many units a year, so as long as the preparation of a few million, enough for two years or even longer, the problem is not big.
