Pocket accelerator vs. desk supercomputers: Tenstorrent picks a different fight

The new local AI arms race: A tale of three boxes.

January 12, 2026

Tenstorrent and Razer are pitching a first-gen, Thunderbolt-attached AI accelerator as a bring-your-own-laptop on-ramp to local inference and edge development, optionally scaled by daisy-chaining up to four units. Nvidia’s DGX Spark and AMD’s Ryzen AI Halo, by contrast, are compact but self-contained systems built around large, unified memory pools and much higher absolute compute budgets. The result is three products that all offer local AI but optimize for very different constraints: portability and modularity (Tenstorrent), peak prefill and Nvidia’s stack (DGX Spark), and general-purpose x86 workstation familiarity and large local models (Ryzen AI Halo). The question isn’t who wins a
