This is designed with two chips and packaged in the wafer base. The chip size is 4.4x6.2mm (27.28mm). Each chip adopts TSMC 7nm process, and one chip is equipped with four Arm.
Cortex-A72 kernel. The main chip contains two L2 caches of 1 megabyte, and TSMC also provides an additional 6 megabyte.
L3 cache improves the overall efficiency of the chip. The nominal maximum frequency is 4GHz, and the measured maximum frequency reaches 4.2GHz( 1.375V). TSMC's focus has changed chip manufacturing and the development of personal computers and mobile phones.
TSMC, which has been doing OEM honestly, has started the division of chip manufacturing: some people specialize in designing chips and some people specialize in manufacturing chips. Because companies like TSMC focus on increasingly complex chip manufacturing, specialized design companies such as NVIDIA, ATI, Qualcomm, Broadcom, Huawei and even Apple can focus on improving chip design. This division of labor has brought the 3D graphics processing revolution in the PC era, and it is also one of the direct contributing factors in the smart phone era. Now the chip industry is talking about autonomous driving, and TSMC is still the pillar behind it.
Taipower's huge investment in the chip production line makes those chip designers no longer need to spend their own money to invest in the production line, reducing the barriers in the design process and the risk of product development failure, thus prompting more small and medium-sized manufacturers to stand out in the semiconductor design process. The division of labor mode initiated by TSMC only focuses on chip production and does not involve chip design, which creates conditions for the birth of a large number of different functional chips needed by mobile phones, and also makes the chips in mobile phones no longer monopolized by only a few chip giants.
In a word, TSMC has the ability to make its own chips. It's like a mud master building a house. He has money, workers, drawings, experience and materials. How can he not build his own house? TSMC is such a local tyrant. It has all the design drawings of OEM chips, so it has many powerful resources to learn. TSMC didn't do this, but it shows that it is very focused.
Only by focusing on one thing can we form a long-term good interest chain and better promote the development of the industry. Therefore, TSMC will not make its own chips, and occasionally show its muscles and see! This is my own chip.
