AMD’s next-generation Instinct MI400 series recently came under fire after it was reported that the lineup was being pushed to the front, but company executives denied this.
AMD’s Instinct MI455X Faces Challenges With N2 Integration, But Team Red Confident in Deployment in H2 2026
When it comes to the race for the best hardware for hyperscalers, NVIDIA has been leading for generations, and we see the gap widening with the Blackwell generation. However, with AMD’s Instinct MI400 series, specifically the MI455X, Team Red believes customers will have ‘no more arguments’ against switching from NVIDIA, given its architectural advancements. However, a SemiAnalysis report revealed that the MI455X will be deployed to customers on a large scale with a delay of almost a year, but AMD’s Vice President of Corporate Software Development, Anush Elangovan, denied the claim.
SemiAnalysis did not specifically highlight the reasons behind the delay, but according to Dylan Patel, AMD faced challenges with N2 integration, which is why engineering samples are on track for H2 2026, but proper token production will not happen before Q2 2027. As we understand, AMD may face challenges in migrating from traditional FinFET to GAA with N2, as this introduces microscopic manufacturing defects, leading to low-volume production initially. Another big challenge with Red Team was managing the scale-up interconnect (UALink) with the new N2 GAA structure, as channel resistance and capacitance were major issues.
Again, on paper, AMD is on track to deploy the MI455X to customers in the coming quarters, but SemiAnalysis’ Dylan believes this will be pushed back to Q2 2027. At the same time, NVIDIA’s Vera Rubin is on track for hyperscaler integration in H2 2026, meaning that if the delay rumors turn out to be true for AMD, NVIDIA will again be the first to offer next-generation infrastructure technology, giving Team Red a much more competitive market, once again. again. MI455X makes its debut.
AMD is struggling to break into the infrastructure segment, with adoption lagging behind NVIDIA, given that the company has faced several challenges in recent quarters, including volume, ROCm disparities, and, of course, NVIDIA being first in meeting customer commitments. The Instinct MI455X is a solid offering on paper, but it will be interesting to see what the timeline from sampling to deployment looks like.
