ArsenalPC ES620 AI Workstation

The ArsenalPC ES620 is a liquid-cooled desktop workstation built around a 16-core AMD Ryzen 9 9950X3D2 processor running at 4.3GHz. It pairs dual NVIDIA GeForce RTX 5090 graphics cards with a combined 64GB of GDDR7 memory and 256GB of DDR5 system memory across four slots. A 4TB NVMe SSD and 1600W power supply complete the platform, which ships with Windows 11 Pro installed.

Suits ML developers and creators needing dual-GPU

This system targets engineers training large models, researchers running parallel inference, and content creators rendering complex scenes who need two RTX 5090 cards in a single validated chassis. Buyers who need more than 64GB of total GPU memory, require ECC system memory, or want a rackmount form factor should evaluate alternative configurations.

64GB combined GDDR7 GPU memory

The dual RTX 5090 configuration provides 64GB of GDDR7 video memory shared across two GPUs connected via PCI Express x16. This capacity determines the maximum model size and batch dimension that fit entirely in VRAM without offloading to system RAM, making it the critical spec for deep-learning workloads.
