AMD Unveils Threadripper Halo Station With Four AI GPUs and Up to 2.6TB Memory

At the heart of the Halo Station is the Ryzen Threadripper PRO 9995WX, based on AMD's Zen 5 architecture and carrying 192 threads. AMD lists up to 2TB of RDIMM system memory, while the accelerator side can add as much as 576GB of HBM3e memory. Together, CPU and accelerator memory can reach 2.6TB, giving large AI models far more room to run locally. AMD also claims up to 16.4TB/s of combined memory bandwidth, giving large datasets rapid access to both system and accelerator memory.

The accelerator configuration can use four Instinct MI350P units, with each device carrying 144GB of HBM3e memory and 4TB/s of bandwidth. That design gives the machine a much larger high-speed memory pool than typical professional desktops built around a single graphics card. The system can handle frontier-class models while supporting hundreds of AI agents operating within the same local environment, according to AMD. Its main role is running, training, and fine-tuning large AI models that would normally require access to expensive remote computing infrastructure.

AMD says the workstation is intended for development tasks where repeated cloud transfers create delays, added costs, or data control concerns. The company also says the design allows sensitive data and intellectual property to remain on premises instead of moving through external cloud services. AMD compares the Halo Station with Nvidia's DGX Station, whose GB300 platform offers 748GB of coherent memory across its CPU and GPU resources. The comparison highlights AMD's focus on memory capacity rather than treating processor core count as the main selling point.

Pricing has not been announced. Industry estimates suggest a fully equipped system could cost around $150,000, reflecting the combination of a high-end CPU, multiple AI accelerators and several terabytes of memory. AMD senior vice president Jack Huynh described the device as “the most powerful workstation in the world,” emphasizing its computing scale. Rack-mounted systems can cost far more than desktop workstations, so the Halo Station is not necessarily the world's most expensive computer.

Editor's Summary

AMD's Threadripper Halo Station packages a 96-core CPU, four Instinct MI350P accelerators and up to 2.6TB of combined memory into a deskside AI workstation. AMD plans commercial availability in 2027 and has not announced pricing, though estimates put a full configuration near $150,000. The system is aimed at local training, fine-tuning and running of large AI models, with a memory capacity that AMD contrasts against Nvidia's DGX Station.
