#AMD Says “#Helios” Racks And #MI400 Series #GPU On Track For 2H 2026
AMD has been working on the Open Rack Wide v3 specification, a double-wide rack that AMD calls “Helios” and that is the platform for delivering #rackscale compute based on the “Altair” MI400 series GPU accelerators. This series includes the #MI450, #MI430X, and the #MI455X for the Helios rackscale systems, which will have 64, 72, or 128 GPUs per system, and possibly MI440X for eight-way system nodes.

#AMD threatens to go medieval on Nvidia with #Epyc and #Instinct: What we know so far
AMD teased its next-generation #AI accelerators at #CES2026, with CEO Lisa Su boasting the #MI500-series will deliver a 1,000x uplift in performance over its two-year-old #MI300X #GPU.
if AMD wants to stay competitive with Nvidia, MI500-series will need to deliver performance on par with if not better than Rubin Ultra Kyber racks.
AMD joins the #rackscale race with #MI455X #Helios racks.

#AMD touts Instinct #MI430X, #MI440X, and #MI455X #AI accelerators and #Helios #rackscale AI architecture at CES — full MI400-series family fulfills a broad range of infrastructure and customer requirements
The newly disclosed MI440X and MI455X are set to be optimized for low-precision workloads, such as FP4, FP8, & BF16. The previously disclosed MI430X targets both sovereign AI and #HPC thus fully supports FP32 and FP64 technical computing and traditional #supercomputing

#HPE to ship #rackscale #AI system using #AMD's #Helios in #2026
Announced ahead of HPE's Discover event in Barcelona this week. Helios is intended to operate a rack full of nodes fitted with accelerators as if they were one single large #GPU, like Nvidia's DGX GB200 NVL72 system, to which Helios is pitched as a rival. Helios will be a vehicle for its next-generation Instinct #MI455X GPUs and its 6th-gen Epyc CPUs, codenamed Venice, both of which are due next year.
