Huawei's newly released nova12 brings two new chips – the Kirin 9000SL and the Kirin 8000. Judging from the test data, these two chips are not much different from Qualcomm's Snapdragon 870 and Snapdragon 778G in terms of performance, only a slight gap. However, there is no definite statement about the process of the Kirin 9000SL and Kirin 8000, as well as the foundry. However, judging from the naming and architecture of the Kirin 9000SL, we can guess its **, which is the chip that the Kirin 9000S was repurposed after yield control.
The Kirin 9000S uses an 8-core and 12-thread design, specifically, including one custom A34 core (2 threads), three custom A78AE cores (6 threads) and four A510 cores, with a maximum clock speed of 262ghz。The GPU model is Maleon, and the architecture has not yet been disclosed. The Kirin 9000SL uses 1 235GHz large cores (2 threads), 2 pcs 215GHz medium core (4 threads) and 3 1The small core of 53GHz is also equipped with マヨオオンンプ. Compared with the Kirin 9000S, the difference between the Kirin 9000SL is: 1. The frequency of the large core is from 262GHz down to 235ghz；2. The middle nucleus changes from 3 to 2, and the small nucleus changes from 4 to 3;3. The middle core is reduced by one, and the number of threads is missing, and the small core is also reduced by one, and finally the number of threads is reduced by 3, so the total number of cores is 6, and the total number of threads is 9. It can be seen that the Kirin 9000SL is actually more like a product after shielding off 2 cores and reducing the frequency of large cores.
It is likely that Huawei will not produce chips with only 6 cores on its own, because this is not a cost-effective approach. So why does the Kirin 9000SL only have 6 cores?Why block out 2 of the cores?In fact, there will be certain yield problems in the production process of chips. A chip with reduced yield does not exactly mean that it is completely unusable, it is likely that there is a problem with some of the modules in it. So we can block out those parts that are problematic and move on. Due to the yield problem of Kirin 9000s, there will inevitably be some chips that cannot meet its standards, and some of those chips that cannot meet the standards only have some problems with the core. Therefore, after shielding the problematic core, the Kirin 9000SL was born. This is actually not the first time Huawei has launched similar products, there have been similar examples before, such as Kirin 820E is a special version of Kirin 820, with only 6 CPU cores, Kirin 990E is a special version of Kirin 990, GPU from 16 cores to 14 cores, NPU from dual large cores to single large cores, etc. Therefore, the Kirin 9000SL is based on the Kirin 9000s, which is repurposed by the chip after yield control.
From the naming and architecture of the Kirin 9000SL, we can speculate that the Kirin 9000SL is a chip reused by the Kirin 9000S after yield control. By shielding out some of the problematic cores and reducing the frequency of the large cores, Huawei has successfully re-enabled those chips that originally failed to meet the standard. This approach is not uncommon in Huawei's chip design, with similar examples such as the Kirin 820e and Kirin 990e. On the one hand, this approach can improve the utilization rate of chips, reduce the waste of resources, and on the other hand, it can also ensure the stability and performance of the product. Therefore, the launch of the Kirin 9000SL is an economical and viable option for Huawei.
In the future, Huawei is expected to further optimize the chip manufacturing process, improve the level of yield control, and reduce the generation of problematic chips. At the same time, we will continue to pay attention to and invest in new technologies, continue to improve chip performance, and bring users a better user experience. The launch of the Kirin 9000SL will bring new options to the smartphone market and will also drive competition and innovation in the industry.
