However, AMD and lattice core still maintain a very close cooperation. Even if lattice core gives up 5nm / 7Nm, amd still hands over 12NM / 14nm IO die in the core to lattice core for exclusive OEM on the sharp dragon processor.
After investigation, in the 8K document updated by the securities and Exchange Commission of the United States, the wafer supply agreement of the two companies has been adjusted, that is, the seventh edition of the amendment. In the seventh edition signed in January 2019, the two sides agreed to cooperate until 2024. The terms of the first three years (2019-2021) have been made clear, and the remaining three years (2022-2024) are scheduled for communication. At the same time, amd can choose other manufacturers' 7Nm and more advanced process, but 12NM and more mature process must be exclusively handed over to lattice core.
The amendment specifies the cooperation in the next three years,And the end time is extended from March 31, 2024 to December 31, 2024. The most important change is that AMD can choose any manufacturer for any process, and decouple from lattice core.
In fact, the reason is very simple. The most advanced manufacturing process of lattice core stays at 12NM, and AMD can't always accompany it. In the future, I / O die must be upgraded to 7Nm and 8nm, which lattice core can't provide.
Of course, with the signing of this agreement, Gexin will have a guaranteed income, that is, whether amd uses enough of these wafers or not, the money will have to be paid. It is said that AMD will purchase 1.6 billion US dollars of chips in Gexin in the next three years. The outside world is also very puzzled, why there is such a large amount.
