AMD Says “Helios” Racks And MI400 Series GPUs On Track For 2H 2026

we sat in on a conference call hosted by New Street Research last week, where Forrest Norrod, general manager of the Data Center Solutions business group, and Doug Huang, one of the co-founders of ZT Systems, which was acquired by AMD last year to underpin its rackscale system engineering efforts, and now its senior vice president in charge of the Data Center Platform Engineering group.
Norrod was having none of it when asked about a delay with the Helios racks:
“I have no idea where this purported issue around thermals is coming from,” Norrod said unequivocally. “I literally have no idea. We have no significant thermal issue. The risk around the thermal design at the component level all the way through the rack level was retired quite some time ago. So, no idea where that’s coming from. I think the meta question that you are asking is when we expect to see the ramp, and are we on track. Lisa showed the first silicon, we are right on track with where we thought we would be, both in terms of the readiness of the overall solution as well as the readiness of the silicon. And we are highly confident of ramping Helios in high volume in the second half of the year.”
So that is that. The reason why AMD can be confident was explained by Huang, who showed off two charts, and explained that they use what amounts to dummy hot plates to simulate the CPUs and GPUs long before they come back from the fabs so they know the physical specs and thermals of the chips that will come back will fit into the racks and the racks will work right.
This may be AMD’s first rackscale design, just like the NVL36 and NVL72 rackscale machines that were supposed to be based on Hopper were – and never came to market except for one machine sold to AWS. But this is not the first rackscale machine that ZT Systems has developed, and it is not the first one for Meta Platforms, either, which started the Open Compute Project back in 2011 with server, rack, and datacenter designs. Getting Helios out the door on time and being manufactured in volume is why
AMD spent $4.9 billion to acquire ZT Systems back in August 2024. Not wanting to be in the server manufacturing business is why
AMD sold the manufacturing arm of ZT Systems to Sanmina for $3 billion last fall.
