For years, we’ve celebrated AMD’s incredible resurgence, from the Ryzen revolution to challenging NVIDIA in the GPU space, and perhaps most crucially, innovating with technologies like 3D V-Cache. We here at eTeknix have dedicated content to how this stacking technology fundamentally changed the game, giving AMD a unique edge, particularly in gaming. It was innovation we could all see and feel in our framerates.
But on November 3rd, 2025, an invisible threat emerged that could fundamentally shake AMD’s very foundations and, by extension, impact every enthusiast who cherishes their 3D V-Cache CPU or looks forward to AMD’s next-gen AI chips. That threat comes in the form of a lawsuit filed by a company called Adeia.
What are Adeia
Adeia, a name many of you likely haven’t heard, is not a rival chip designer. They don’t manufacture anything. Instead, they are a technology licensing company, often controversially labelled a “patent troll” by critics, whose business model revolves around intellectual property, and they’re suing AMD, alleging infringement on ten crucial patents related to semiconductor manufacturing.
With these lawsuits, the stakes are enormous. Adeia isn’t just seeking monetary damages; they are pursuing an injunction that could, if granted, force AMD to stop manufacturing, selling, and even importing some of its most successful products, including the beloved Ryzen X3D CPUs and potentially its next-generation AI accelerators. This isn’t just about money; it’s about potentially halting the very innovation that has defined AMD’s recent success.
So What’s Happening?
So today is a bit of a different one, but we’re going to be looking into this legal bombshell. We’ll talk about who Adeia is and their history of patent litigation. We’ll also look into the heart of the dispute with those ten patents and why they’re so critical to AMD’s 3D V-Cache and advanced packaging along with what immense financial and strategic implications this could cause for AMD, especially in the booming AI market, before looking at the likely outcomes, the industry’s response, and what this potentially means for your next CPU purchase. So buckle in as there’s a lot to go through.
