Super Micro Computer shares SMCI climbed 11% on Wednesday as the server maker began shipping a new generation of AMD-powered systems for artificial intelligence workloads.
The gains were also supported by a recovery in its major customer, CoreWeave, following better-than-expected quarterly results and an improved financial outlook.
Super Micro stock rose 11% to $31.02, while CoreWeave shares gained 25.6% to $61.22 after the AI cloud infrastructure provider reported its third-quarter earnings.
The rebound helped ease concerns about the financing of large-scale AI data centre projects.
AMD-powered servers expand Super Micro’s AI offering
Super Micro said it had started shipping its H15 generation servers powered by AMD’s sixth-generation EPYC 9006 processors.
The systems are designed for cloud computing, high-performance computing, AI inference, and agentic AI applications.
The servers can also work with AMD’s Instinct accelerators, which are designed for demanding AI workloads.
Agentic AI refers to systems capable of carrying out tasks through multiple steps with limited human intervention.
Super Micro said its H15 systems offer up to 33% more processor cores, twice the PCIe bandwidth and 2.6 times the memory bandwidth compared with previous-generation systems.
The company also said its AMD-powered infrastructure can deliver up to 1.8 times as many tokens per second for frontier-model host nodes.
Tokens are units of information processed by AI models.
The H15 portfolio includes more than 20 systems for different computing requirements.
Super Micro added that its 2U Hyper and CloudDC server platforms had achieved multiple SPEC CPU benchmark world records.
The company is also expanding its rack-scale infrastructure through two platforms developed with AMD.
Helios uses AMD Instinct MI455X GPUs for large-scale AI training and inference, while Helion uses sixth-generation EPYC processors for compute-intensive workloads.
Both platforms are designed to integrate with Super Micro’s Data Center Building Block Solutions, which combine computing, networking and cooling infrastructure.
CoreWeave recovery provides additional support
Super Micro’s share gains came alongside a sharp recovery in CoreWeave, one of its largest customers.
Susquehanna analyst Mehdi Hosseini told Barron’s that CoreWeave was among Super Micro’s largest customers, if not its largest, and that the cloud provider’s earnings beat and improved guidance were helping lift Super Micro shares.
CoreWeave had faced pressure over the previous month amid concerns about its debt burden and a possible slowdown in AI data centre construction.
Despite Wednesday’s rebound, its shares remained down 25% over the month and 16% for the year.
Super Micro, by comparison, was up around 4% for the year before Wednesday’s move.
However, the company’s dependence on major customers remains a concern.
Raymond James analyst Simon Leopold previously identified customer concentration as one of the key risks facing Super Micro.
SpaceX has also been named as a potential major customer, although neither company has confirmed the relationship.
