This tiny PC has two Intel Arc B70 GPUs with 64GB of RAM and water cooling — Gunnir B70 workstation runs on Intel's Ultra 200HX with no AMD version in sight

Gunnir fits two Arc Pro B70 graphics cards inside one compact workstation Each Arc Pro B70 card carries 32GB of GDDR6 ECC graphics memory The dual GPU workstation provides 64GB across two separate graphics processors At the recent Intel Connection 2026 event in China, hardware manufacturer Gunnir sh
