ABS ZRT9965WX-3XR9700 workstation, Threadripper Pro 9965WX, 128GB DDR5, 2x 2TB NVMe, 3x R9700 96GB VRAM

AI workstation for local LLM inference

This ABS ZRT9965WX-3XR9700 tower workstation combines a 24-core AMD Ryzen Threadripper 9965WX processor at 4.2GHz with three AMD Radeon AI Pro R9700 GPUs delivering 96GB aggregate GDDR6 VRAM. It targets organisations that need to run 70B-class models on-premises without cloud dependency. The system ships with Ubuntu and the open ROCm stack for PyTorch and vLLM workflows.

PCIe bandwidth and VRAM ceiling

Each R9700 connects over the motherboard's PCIe lanes, so total throughput depends on the WRX90 chipset's lane allocation and the CPU's 24 cores keeping all three GPUs fed. The 96GB combined VRAM sets a hard limit on model size and context length; larger quantised models or longer sequences will exceed device memory and force offload to system RAM.

128GB ECC DDR5 with 1TB headroom

The installed 128GB DDR5 ECC RDIMM configuration occupies half of the eight available slots, leaving capacity for expansion up to the platform maximum of 1TB. Two 2TB NVMe SSDs handle the operating system and active datasets. Workloads that outgrow GPU memory can spill into system RAM, but throughput drops once the 96GB VRAM boundary is crossed.
