Vultr has revealed it will offer the AMD Instinct MI455X GPU and support for AMD’s Helios rackscale solution via its cloud platform.
The company is currently accepting preorders for the hardware, which will be offered starting in Q4 2026.
AMD launched its MI400 series GPUs earlier this month, including the MI455X and MI430X GPUs. The former is designed for AI training and inference, and the latter targets sovereign AI and HPC workloads.

The chips are built with the company's new CDNA 5 architecture and on a 2nm process node. Each MI455X GPU includes 432GB of HBM4 memory, a 1.5x increase over the 288GB of HBM3E in the MI355X, with around 2.9x the peak memory bandwidth. They include 3.6 TBps of low-latency scale-up bandwidth across 36 links.
