What are the internal secrets of Huawei Kirin 980 core photos? How big is the core area of ​​Huawei Kirin 980?

Huawei Kirin 980 is the first publicly announced mobile chip with 7nm process. TSMC is a foundry and integrates as many as 6.9 billion transistors. However, the core area has been kept secret, only less than 100 square millimeters, which is easy to think It will be 90+ square millimeters.

Now, ChipRebel has released the core photos of Kirin 980 for the first time, finally revealing many internal secrets.

In one corner can be seen the marking HI3680 V200.

First of all, it can be confirmed that the core area of ​​the Kirin 980 is only 74.13 square millimeters, which is not only much smaller than the official range, but also 30% smaller than the Kirin 970’s 96.72 square millimeters. It can be seen that TSMC’s 7nm is really powerful.

AnandTech also draws the distribution of different modules based on the kernel photos:

In the upper left corner is the Mali-G76 GPU, with a total of 10 cores. The biggest feature is that the computing power is doubled, which is almost equivalent to 20 cores of the previous generation G72.

The upper right corner is the CPU. For the first time, Kirin adopts the DynamIQ configuration, including two A76 large cores, two A76 medium cores, and four A55 small cores.

Note that the A76 core is divided into two groups, and the physical layout of each group is obviously different. Obviously, it has its own voltage and frequency control layers, which are optimized for different high and low frequencies.

In the middle of the eight CPU cores is the DSU, which is the DynamIQ Share Unit (dynamically configured shared unit), and the 4MB L3 cache.

In addition, four sets of LPDDR4X memory controllers can be seen, but the cores of the two NPU neural network units cannot be found, and there is no area that is exactly the same as the two songs. Are the two cores different?
