VPX3U-A4500E-HPC (WOLF-144Y)

NVIDIA Ampere, 5888 CUDA Cores, 160 Tensor Cores, HPC

  • NVIDIA RTX™ GA104 GPU with 5888 CUDA Cores, 184 Tensor Cores
  • 16 GB GDDR6 256-bit memory with up to 512 GB/s
  • 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. WOLF’s advanced cooling technology is designed to move heat using a low weight, high efficiency path from the GPU die to the wedgelocks.
