While Nvidia continues to dominate the AI accelerator market with a share of over 90%, its closest rival AMD has signed a deal with Oracle on Monday to build a cluster of 30,000 MI355X AI accelerators.
The new MI355X Instinct now expected to arrive by mid-2025, is manufactured on TSMC’s 3nm node and built on AMD’s new CDNA 4 architecture. It will feature 288GB of HBM3E memory, bandwidth of up to 8TB per sec, and support for FP6 and FP4 low-precision computing. It is positioned as a rival for Nvidia’s Blackwell lineup.

This news was revealed during Oracle’s recent Q2 2025 earnings call, where Chairman and Chief Technology Officer Larry Ellison told investors, “In Q3, we signed a multi-billion dollar contract with AMD to build a cluster of 30,000 of their latest MI355X GPUs.” He also went on to talk about Oracle’s technological edge. The move also strengthens Oracle’s hand in the AI cloud race, following earlier shipments of MI300X GPUs to both Oracle and Vultr.
Meanwhile, Ellison also discussed the Stargate Project. “We are in the process of building a gigantic 64,000 GPU liquid-cooled Nvidia GB200 cluster for AI training,” he said. He also added, “Stargate looks to be the biggest AI training project out there, and we expect that will allow us to grow our RPO even higher in the coming quarters. And we do expect our first large Stargate contract fairly soon.”
When asked further about Stargate, he said “the capability we have is to build these huge AI clusters with technology that actually runs faster and more economically than our competitors. So, it really is a technology advantage we have over them. If you run faster and you pay by the hour, you cost less. So that technology advantage translates to an economic advantage which allows us to win a lot of these huge deals.”
