Evidence
All leading AI accelerators deployed for GenAI training and inference use HBM.
Context After
In this report, we will examine HBM’s present state, what’s happening in the supply chain, and the groundbreaking changes happening in the future. We’ll examine HBM’s critical role in AI accelerator architecture, the impact HBM is having on the DRAM market, and why it is upending the way memory market analysis is being performed. For subscribers, we will also address the major questions on Samsung’s future viability as a supplier, as well as highlight one technological change that may reverse the trend of increasing HBM capacity.
