Dell Precision 3490 Mobile Workstation AI PC… vs Dell Precision 7670 16.0" 500nits FHD… — Head-to-Head (2026)

Our verdict

Dell Precision 3490 Mobile Workstation AI PC… is our pick.

For most 2026 mobile-workstation buyers, the Dell Precision 3490 is the better machine — its Core Ultra 7 155H (16 cores/22 threads), 64GB of DDR5, 2TB SSD, and 3.1 lb chassis beat the 2022-vintage Precision 7670 on nearly every axis, and the only thing the 7670 wins is a dedicated RTX A2000 8GB GPU for CUDA work.

Buy the Precision 3490 if you want a modern, portable 2025-platform workstation with maximum CPU cores, RAM (64GB), storage (2TB), and an NPU for on-device AI. Buy the Precision 7670 if — and only if — your workflow genuinely needs the dedicated RTX A2000 8GB GPU for CUDA, GPU rendering, or ISV-certified viewport acceleration and you can live with half the RAM and an older i5.
