ArsenalPC ES620 Dual GPU Workstation

This ArsenalPC ES620 is a liquid-cooled desktop workstation built around an AMD Ryzen 9 9950X 16-core processor running at 4.3 GHz and two NVIDIA GeForce RTX 5090 graphics cards. It ships with 256 GB of DDR5 memory, an 8 TB NVMe SSD array in RAID, and a 1600 W power supply under Windows 11 Pro.

Suited for local AI training and heavy rendering

Developers and researchers who need dual-GPU compute for large model training or high-resolution rendering will match this configuration. Buyers who only need single-GPU performance or who work within a smaller power envelope should consider a different build.

Dual RTX 5090 configuration

The defining specification is the paired RTX 5090 GPUs, each equipped with 64 GB of GDDR7 memory. This twin-card layout determines whether the system fits workloads that scale across multiple accelerators or exceed single-card memory limits.

Questions about this item

What does the 16-core Ryzen 9 9950X at 4.3 GHz deliver in a real workstation?

The 16-core processor running at 4.3 GHz provides a strong CPU foundation for local development, content creation, and data-heavy workloads, backed by liquid cooling to sustain performance.

How does the 2.5G Ethernet port cap network throughput in practice?

The 2.5G Ethernet connection limits wired network speeds to 2.5 gigabits per second, which is the maximum throughput the port can handle.

What does the 360 mm liquid cooler require for mounting inside the ES620 case?

The 360 mm liquid cooler is pre-installed in the ES620 chassis, so no additional mounting steps or bracket compatibility checks are needed.
