Two New Product Lines Go Live: AI Compute Servers and Junhangclaw Inference Workstations

JH Semiconductor's website now hosts two new product lines: AI compute servers and Junhangclaw AI inference workstations. The compute spectrum runs from 50 TOPS on a personal desktop to rack-scale liquid-cooled training clusters, joining the existing enterprise storage, memory, and GPU supply-chain businesses into one-stop compute-plus-storage supply.

50 TOPS or 2,070 TFLOPS: A Selection Guide to the Four Junhangclaw Inference Workstations

The W50, W120, W280, and W2000 map to four user profiles: individuals, small teams, government/enterprise xinchuang, and desktop flagship. This guide compares them by compute tier, chip route, and data boundary, and explains why the W2000's 128GB LPDDR5x unified memory matters for running large models locally.

After 600W per Card: Where Air Cooling Ends and Cold-Plate Liquid Cooling Begins for 8-10 GPU Servers

With GPUs drawing up to 600W per card, cooling selection for 8-10 GPU servers is no longer a matter of preference. This post maps the boundaries of JH Semiconductor's three cooling routes: the preconditions under which the RTX 6000D platform's independent CPU/GPU airflow ducts and the Thor T5000 platform's high-volume air cooling hold up, the three things cold-plate liquid cooling (full CPU/GPU coverage, CDU connection, supply/return water monitoring) buys in high-power-density and low-PUE scenarios, and which three kinds of users the 8-GPU air-cooled platform — positioned to lower the liquid-cooling retrofit barrier — actually fits.

PC-Farm 4U4H/6U6H: Pluggable PC Nodes in a Standard Rack — Maintenance Granularity, the 750W Backplane and Redundant Power Design

JH Semiconductor's PC-Farm distributed node servers pack four (4U4H) or six (6U6H) pluggable PC nodes into a standard rack chassis. This post explains the workload shape this form factor targets: why node hot swap plus fully independent power control cuts maintenance granularity and the failure domain down to a single node, what the two-layer power design — a 750W-peak-per-node backplane and four redundant CRPS 1100W supplies — actually means, and why one GPU card per node happens to match count-scaled businesses such as render farms and batch inference.
