PNY RTX A4500 20GB GDDR6 workstation
The 20GB GDDR6 ECC memory and 7168 CUDA cores on the Ampere-based RTX A4500 provide a stable, high-capacity platform for complex 3D rendering and AI model training. Its compact, single-slot design with four DisplayPort 1.4a outputs and a 200W power envelope allows for dense multi-GPU workstation configurations without excessive thermal load. This card is best for data scientists and engineers running memory-intensive simulations or AI inference in space-constrained server environments.
