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.

Questions about this item

Should I pick the 24-core Threadripper Pro 9965WX or a higher-core model for three R9700 GPUs?

The 24-core 4.2 GHz Threadripper Pro 9965WX feeds all three GPUs with 48 threads, matching the 70B-class LLM workload this workstation targets.

What does the 96 GB total VRAM figure mean when I run a 70B-parameter model locally?

96 GB of GDDR6 across three R9700 cards lets you load a 70B model with long context windows entirely in GPU memory for fast inference.

Does the WRX90 chipset and PCIe layout let each R9700 use full bandwidth?

The Gigabyte MH53-G40 motherboard on the WRX90 platform connects the 24-core CPU and three GPUs for high-throughput AI pipelines.
