The AMD Instinct MI455X GPU, built and deployed into production by DALCO.
The MI455X pairs 432 GB of ultra-fast HBM4 memory with industry-leading low-precision compute, delivering up to 4x the 4-bit and 8-bit matrix performance of the previous-generation AMD Instinct MI355X. Built in a multi-chip package on TSMC 2nm/3nm process technology, it is designed from the ground up to operate as one of 72 GPUs inside a single AMD Helios rack, not as an isolated accelerator. DALCO engineers this into systems sized to the customer.

AMD Instinct MI455X GPUs with peak OCP MXFP4 are expected to offer up to 4X better peak theoretical performance compared to AMD Instinct™ MI355X GPU.
AMD Instinct MI455X and MI430X GPUs offer 50% more memory capacity and 6% higher peak memory bandwidth compared to its competitors.
The AMD Helios rackscale solution, powered by AMD Instinct MI455X GPUs, is expected to offer up to 15% better OCP MXFP4 peak theoretical performance compared to its competitors.
AMD Instinct MI430X GPUs are expected to offer up to 8.7X more FP64 peak theoretical performance than its competitors.
A unified AI platform for training, fine-tuning, and inference.
High core count for heavily parallel professional workloads.
Professional-grade memory bandwidth and platform security.
Server-class silicon in a deskside workstation chassis.
Single-socket 1U rack server for dense general-purpose workloads.
A 1U chassis built around a single AMD EPYC socket, tuned for the highest possible core density per rack unit. Front-serviceable drive bays and redundant power keep maintenance windows short.
Single-socket 2U platform with room for storage and expansion.
The 2U form factor keeps the single-socket simplicity but doubles the drive budget and adds full-height expansion slots, so storage and networking can grow without changing platform.
Dual-socket 2U server for heavily parallel and memory-bound workloads.
Two AMD EPYC sockets share 24 DIMM slots and a wide PCIe budget, giving simulation and database workloads both the core count and the memory bandwidth they need.
Entry-level storage server on a single AMD EPYC socket.
The starting point of the storage range: a top-loading chassis that keeps cost per terabyte low while still exposing enough PCIe lanes for high-speed networking.
Dual-socket storage node for parallel filesystems.
A second AMD EPYC socket doubles the memory channels, which is what keeps metadata operations responsive once a filesystem grows past a few hundred million objects.
High-capacity dual-socket platform with expanded drive count.
More spindles per rack unit without giving up compute: the same dual-socket layout, in a chassis built for capacity-first deployments.
Maximum-density storage server for petabyte-scale tiers.
The top of the AMD storage range — the highest drive count we ship in a single chassis, paired with enough network bandwidth to actually saturate it.
