Context Before

AMD Advancing AI: MI350X and MI400 UALoE72, MI500 UAL256

For the past six months, AMD has been in a Wartime stance ↗. They have been working hard and working smart towards their goal of being competitive with Nvidia. At its Advancing AI 2025 event, AMD launched the MI350X/MI355X GPUs which could be competitive to Nvidia’s HGX B200 solutions for inference of small to medium LLMs on a performance per TCO basis. Notwithstanding the reality distortion field projected by AMD, the MI355X is not a rack scale product, and it is not competitive against Nvidia’s GB200 NVL72 at frontier model inference or training.

Evidence

Instead, it is the MI400 Series that is a true rack scale solution that could potentially be competitive with Nvidia’s VR200 NVL144 rack scale solutions in H2 2026.

Context After

In this article, we will discuss the relative competitiveness of AMD’s new products and analyze their total cost of ownership. We will also elaborate on AMD’s new hyperscale customer, AWS, and on the flip side, the continued disappointment in follow-on orders on from existing customer Microsoft.

Recently, Nvidia has upset quite a few of their Neocloud partners with the launch of DGX Lepton Marketplace, which aims to commoditize compute. We believe that this development has also helped to open up a window of opportunity for AMD to foster their own Neocloud ecosystem. We will explain how AMD is more willing to invest into Neoclouds, the clever financial engineering they are employing to help out these Neoclouds, as well as the investment AMD is making into their own internal development R&D clusters.
