It is an attempt to fit within the limitations
Chinese startup Biren Technology and Alibaba are slowing down their most advanced processors in an effort to avoid US sanctions. These processors were already developed and are now in production. They are however manufactured at Taiwan Semiconductor Manufacturing (TSMC) and are therefore subject to US restrictions. TSMC has not yet commented.
The new Alibaba chip is believed to have been the basis of new GPUs being made in China. It will now have to be artificially slowed due to Washington’s sanctions. The bidirectional transfer rate of chips should not exceed 600GB/s.
It is worth noting that the Biren BR100 computing accelerations had a speed rating of 640 GB / s. A Biren employee, who spoke on condition of anonymity, stated that this is an attempt to bypass the sanctions and get production started on TSMC lines. The design of the chips is the same, so it’s not clear if this trick will work.
Alibaba T-Head also plans to modify its 5nm AI processor. This could take some time and cost money.
It was reported that Japan had allocated $2.4 Billion to develop 2-nanometer chips with the United States.
