How Many GPUs Fit in 4U? TFNEW Launches F6008
TL;DR: TFNEW launched the F6008, a 4U rackmount GPU AI server chassis, on September 19, 2026. It holds up to 8 dual-slot GPUs, 4+ PCIe Gen 5.0 x16 slots, U.2 NVMe drive bays, redundant CRPS (1+1) power and BMC (IPMI/Redfish) management. It targets enterprise AI training, inference and HPC workloads that have outgrown 2U GPU servers. Specs and pricing: sales@tfnew.com.
Core Specifications (with Plain-Language Terms)
The F6008 is a 4U rackmount chassis — 4U means 4 rack units, about 17.8 cm tall, the standard height most datacenters reserve for GPU servers. It accepts up to 8 dual-slot GPUs (cards that occupy two expansion slots for thicker heatsinks and 350W+ power draw), with multiple PCIe Gen 5.0 x16 slots, U.2 NVMe drive bays and redundant CRPS (1+1) power supplies — two power modules running in parallel, so one failure does not stop the machine. Management is handled by BMC with IPMI and Redfish options, the two standard interfaces for remote power control, health monitoring and firmware updates.

F6008 vs a Typical 2U GPU Server
| Item | F6008 (4U) | Typical 2U GPU server |
|---|---|---|
| Rack height | 4U ≈ 17.8 cm | 2U ≈ 8.9 cm |
| Dual-slot GPUs | Up to 8 | Usually 2–4 |
| PCIe | Gen 5.0 x16, multiple slots | Gen 4/5, fewer slots |
| Power redundancy | CRPS 1+1 standard | Often single, redundant optional |
| Cooling headroom | Taller chassis, larger fans | Limited by 2U height |
| Typical use | 8-GPU AI training nodes | General compute, lighter AI |

Why the Numbers Matter
GPU density: an 8-GPU F6008 node can replace 2–3 typical 2U GPU servers in a rack, freeing space for storage and networking. Bandwidth: each PCIe Gen 5.0 x16 slot delivers about 128 GB/s of bidirectional bandwidth per direction (64 GB/s per direction), enough to feed modern accelerators without a bottleneck. Reliability: redundant CRPS (1+1) and hot-swap fans mean a failed power module or fan can be replaced while the system keeps running — important for 24/7 training jobs. Management: BMC with IPMI/Redfish gives the same remote control used by enterprise datacenter teams.
Where the F6008 Fits
- AI training teams: run large model training with up to 8 GPUs in one compact node instead of spreading across 2U boxes
- Enterprise inference: host production LLMs and vision models with predictable per-rack capacity
- HPC and analytics: simulation, engineering analysis and data processing with high PCIe throughput
- Server integrators: a validated base chassis to build custom GPU systems without redesigning cooling and power
What TF NEW Says
"We built the F6008 for teams that keep hitting the same wall: 2U servers run out of GPU slots long before they run out of rack space," said a TF NEW product manager. "Eight dual-slot GPUs, Gen 5 PCIe and redundant power in one 4U chassis is a straightforward answer, and it is the kind of spec sheet customers can plan a rollout around."
