. This represents a market approaching the size of the entire semiconductor industry today, driven largely by the rise of agentic AI1
.Su explained that agentic AI creates a step change in compute demand because when you ask an agent to complete a task, "it actually has dozens of steps, and it has to reason, and it has to call tools, and it has to access data, and it has to keep doing it over and over until it solves the problem, and so you need lots of GPUs to do all that"
1
. GPUs are expected to constitute the vast majority of this market because algorithms remain in their infancy and workloads continue evolving, favoring programmability in the silicon ecosystem1
.Microsoft will also leverage AMD's upcoming Epyc Venice CPUs, adding two new Azure VM series: the HDv2 series for agentic AI and data pipelines, and the HXv2 for semiconductor design workflows
