VPX3U-A4500E-VO (WOLF-1448)

NVIDIA Ampere, 5888 CUDA Cores, 160 Tensor Cores, 4 DisplayPort Out

  • NVIDIA RTX™ GA104 GPU with, 5888 CUDA Cores, 184 Tensor Cores, 46 RT Cores, 4 DisplayPort outputs
  • 16 GB GDDR6 256-bit memory with up to 512 GB/s
  • PCIe x16 Gen4 with a configurable PCIe switch
  • Module power: 70W-160W, configurable



The VPX3U-A4500E-VO module includes an NVIDIA RTX™ A4500 embedded GPU in a rugged 3U VPX module. Built on the NVIDIA Ampere architecture this GPU includes CUDA cores for parallel processing, Tensor cores for dedicated AI-accelerated compute, and Ray Tracing cores for superior rendering speeds. This module also includes a configurable PCIe Gen4 switch.

The NVIDIA Ampere architecture has introduced many significant improvements to the performance and efficiency of the GPU, with more flexible CUDA FP32/INT core use, more efficient third generation Tensor cores, and second generation RT cores. The Ampere GPU fabrication uses an 8nm manufacturing processing providing significant power improvements which, along with other Ampere architecture improvements, can provide up to 154 GFLOPS/W, providing almost twice the performance per slot compared to the previous Turing generation’s 86 GFLOPS/W or the Pascal generation’s 62 GFLOPS/W.

Unlocking the best performance requires the best cooling capability. This module takes advantage of WOLF Advanced Metal, a material which provides lower thermal resistance between the GPU and the wedgelocks, allowing the GPU to run at higher power levels to achieve higher performance.
