CEO Lisa Su says next-gen MI400 GPUs and architecture gaining traction with hyperscalers
AMD plans to launch its Helios rack-scale architecture in 2026 as a direct challenge to Nvidia in the AI infrastructure market, pending successful integration of its next-gen GPUs and processors.
The chip firm's President & CEO Dr Lisa Su talked up its progress in the datacenter, AI, and server businesses during an investor conference call for AMD's third quarter 2025 financial results.
She claimed server CPU revenue reached an all-time high, driven by rapid adoption of AMD's 5th Gen Epyc Turin processors, which accounted for nearly half of overall Epyc revenue during the quarter.
Looking ahead, Su said AMD's datacenter AI business is to enter "its next phase of growth" and customer interest is building ahead of the launch of the next-gen MI400 series GPU accelerators and the Helios rack-scale solution next year.
AMD showed off Helios in June, at an event in San Jose, California. It is designed to operate a rack full of accelerators as if they were one single large GPU, like Nvidia's DGX GB200 NVL72 system.
"Helios integrates our Instinct MI400 Series GPUs, Epyc Venice CPUs and Pensando NICs in a double-wide rack solution optimized for the performance, power, cooling and serviceability required for the next generation of AI infrastructure and supports Meta's new open rack wide standard," Su said on an earning conference call last night.
Venice is the codename for AMD's 6th-gen Epyc CPUs, set to be produced using TSMC's 2nm manufacturing process, also due next year.
"Development of both our MI400 Series GPUs and Helios rack is progressing rapidly, supported by deep technical engagements across a growing set of hyperscalers, AI companies and OEM and ODM partners to enable large-scale deployments next year."
The ZT Systems team, a maker of high-performance servers for cloud operators that AMD acquired last year, is playing a critical role in Helios development, Su added.
In response to an analyst question, she said customers for its MI450 GPU will buy them as part of the rack-scale solutions. "We will have other form factors as well for the MI450 Series, but there's a lot of interest in the full rack-scale solution."
However, AMD has also seen signs of a pickup in CPU demand in the midst of all this AI frenzy.
"A number of our large hyperscale clients are now forecasting significant CPU build into 2026. And so from that standpoint, I think it's a positive demand environment, and it is because AI is requiring quite a bit of general-purpose compute," she explained.
AMD was cagey about when it might start to see the benefits from its rack scale push in its bottom line.
"We're not guiding 2026, but our priority in datacenter GPU business is to really expand the top line revenue growth and the gross margin dollars," said chief finance officer Jean Hu.
Another analyst, Timothy Arcuri of UBS Investment Bank, inquired about AMD's agreement with OpenAI, announced last month.
"It looks like they could be something like half of your datacenter GPU revenue in the 2027, 2028 time frame. So how much risk, in your mind, is there around that single customer for you?" he asked.
Su brushed this aside, saying the deal had been in the works for quite some time, and AMD is happy with the planned scale of the deployments.
"I think we're dimensioning the supply chain in such a way that we would have ample supply to have multiple customers at similar scale as we go into the '27, '28 time frame, and that's certainly the goal," she stated.
Overall AMD's revenue grew 36 percent to $9.2 billion during the third quarter ended September 27, compared with the same period last year. Its datacenter business saw revenue up 22 percent to $4.3 billion, attributed to sales of its Instinct MI350 series GPUs and server share gains.
In client and gaming systems, revenue was up 73 percent to $4 billion, with Su saying that "Our PC processor business is performing exceptionally well with record quarterly sales as breadth of our leadership Ryzen portfolio accelerates growth."
Revenue declined 8 percent year-on-year to $857 million for AMD's embedded portfolio, although the company says it is on track for a second straight year of record design wins, reflecting the growing adoption of its products across a broad range of markets and expanding set of applications.
For the fourth quarter of 2025, AMD forecasts revenue of $9.6 billion, plus or minus $300 million, which would represent year-on-year growth of roughly 25 percent. The firm said that its current outlook does not include any revenue from AMD Instinct MI308 shipments to China. ®
