990A, is changed through the Kirin 990 chip, Kirin 990 adopts 2*A76*2.86GHz,2*A76*2.09GHz, 4*A55*1.86GHz. 16 core G76, then 1, 1, 2 core NPU. The Kirin 990A uses an 8-core CPU, uses Huawei's Taishan V120 Lite kernel in the large core, uses A55 in the small core, the GPU has changed from 16 core to 8 core, and the NPU uses 21 *D100. In terms of process, it was not disclosed, but it is obvious that if it is modified based on Kirin 990, it is definitely based on 7nm process, after all, Kirin 990 is 7nm process.
Kirin 990α is a few nanometers in the nanometer is the shortest distance unit found in modern times, is measured by special instruments, is invisible, the application of nanotechnology has changed people's lives, nanotechnology is a new technology, nanomaterials have also appeared. Kylin is an ancient Chinese fictional animal image, like the dragon, phoenix, etc., is deified, and has nothing to do with nano, let alone numbers.
Kirin 990a is 7 nanometers.
Kirin 990 is a new generation of mobile phone processors developed by Huawei, and the Hisilicon Kirin 990 processor will be manufactured using TSMC's second-generation 7nm process. The Kirin 990 processor will improve overall performance by about 10% over the Kirin 980. On September 6, 2019, Huawei simultaneously released two mobile phone chips, Kirin 990 and Kirin 990 5G, in Berlin and Beijing, Germany.
The Kirin chip 990 series belongs to 7 nanometer technology, and 990a is produced by 7 nanometer process.
