WOLF-2538
Overview

Dual NVIDIA RTX 5000 Ada HPEC with PCIe Gen4 Switch
The VPX6U-AD5000E-DUAL-VO module includes two NVIDIA RTX 5000 Ada embedded GPUs and a PCIe Gen4 switch in a rugged 6U VPX module. The NVIDIA RTX 5000 embedded GPU provides advanced processing capabilities for high performance embedded computing (HPEC) and artificial intelligence (AI) data processing.
The NVIDIA Ada architecture includes CUDA cores for HPEC, 4th generation Tensor cores for AI and data science computations, and 3rd generation Ray Tracing (RT) cores for visually accurate rendering. The Ada GPU uses a new TSMC 4N NVIDIA Custom Manufacturing Process which increases efficiency. The denser Ada GPUs have more CUDA and Tensor cores operating at higher clock frequencies at the same power, delivering significantly more performance per watt compared to the previous generation GPUs. For example, the RTX 5000 Ada GPU can achieve up to four times the GFLOPS/W compared to the RTX 5000 Turing GPU used in the WOLF-2348.
Unlocking the best performance requires the best cooling capability. WOLF’s advanced cooling technology is designed to move heat using a low weight, high efficiency path from the GPU die to the wedgelocks.,

FAQ
Choose WOLF-2538 when you want a dual RTX 5000-class 6U module with strong compute density and multi-display capability, but your platform is standardized around PCIe Gen4 and/or you are optimizing for power, qualification continuity, or system compatibility.
WOLF-2638 is typically preferred when your platform can take advantage of PCIe Gen5 bandwidth headroom and you want the newest-generation GPU baseline.
If the backplane and host ecosystem are Gen4-limited, WOLF-2538 can be the more practical integration choice while still providing dual-GPU density.
It provides the fabric needed to balance PCIe traffic across both GPUs and align to different platform topologies.
In practice it helps with:
- Consistent feeding of both GPUs from the host without one becoming starved
- Cleaner peer/endpoint movement through a centralized PCIe fabric
- Integration flexibility when chassis lane routing differs between programs
The switch is most valuable when you expect multiple system variants or when both GPUs must be fed heavily and consistently.
Confirm these early to prevent late-stage chassis/backplane changes:
- Cooling method: supports conduction-cooled (CC) or liquid flow-through (LFT) (and air-cooled variants are also referenced in configuration examples). Ensure your chassis matches the selected cooling model.
- Slot profile alignment: SOSA aligned profile support 10.6.4—confirm your backplane/slot is designed for that profile family.
- Display routing plan: supports up to 8 DisplayPort outputs with HDMI option by configuration. Decide early how displays are routed (rear I/O expectations) so harnessing and rear transition planning are stable.
For dual-GPU modules, cooling capacity and backplane routing are typically the two dominant integration constraints.
Key ordering-time decisions are integration-driven:
- Cooling variant (CC vs LFT vs AC builds): determines chassis compatibility and sustained power capability.
- PCIe switch configuration: affects PCIe lane allocation and how traffic is balanced across two GPUs.
- Display interface configuration: number of enabled outputs (up to 8 DP) and HDMI option requirements.
- Power threshold (150W-280W envelope): must match chassis thermal headroom for sustained performance.
- COTS/MCOTS/locked and conformal coating: drives qualification approach and configuration control.
