On June 22, Ming-Chi Kuo, a well-known analyst at Tianfeng International Securities, issued an article on Monday saying that Google has deepened its cooperation with MediaTek on the TPU v9 chip and developed an upgraded version code-named Triggerfish, focusing on maximizing AI agents, reinforcement learning and effective computing power.

Ming-Chi Kuo said that his latest industry survey shows that Google will develop an upgraded v9 chip possibly code-named Triggerfish based on TPU v9 (code-named Humufish), and MediaTek will exclusively obtain this new order with a higher unit price.
This upgraded chip is an extension project based on Humufish and is positioned as a revised version of TPU v9 with stronger reasoning capabilities, which can simultaneously alleviate the CPU wall (processor bottleneck) and memory wall (memory bottleneck) problems. This project also further verifies that MediaTek is Google’s preferred partner in the TPU v9 generation.
Compared with Humufish, the main differences of this TPU v9 revised chip include: the static random access memory (SRAM) capacity is greatly increased to 2 to 3 times that of Humufish; a new simulation die (simulation die) is added; and it is upgraded to use HBM4E high-bandwidth memory (Humufish uses HBM4).
In addition to the functions of local TPU management, training and inference mode switching, the new simulation die will focus on the collaborative operation of reinforcement learning (RL) and AI agents. A larger capacity SRAM can keep more of the active working set required for reinforcement learning and AI agents locally on the TPU, thereby reducing data movement costs and improving the execution efficiency of the ultra-low latency decoding stage.
Ming-Chi Kuo said that while the total life cycle shipments of Humufish remain unchanged at the estimate of 4 million to 5 million units, Google is expected to place an additional order of 1 million to 2 million Triggerfish units. The product is expected to start production at the end of 2027 and enter the mass production stage in 2028. Since the unit price of Triggerfish is about 30% higher than that of Humufish, it is expected to become a new driving force for MediaTek's performance growth in 2028.
