SANTA CLARA, Calif. — When EE Times visited Tenstorrent CEO Jim Keller’s office a year ago, the whiteboard outside his office door read: “We’re going to WIN!” On returning a year later, it reads: “Holy Shit, That’s Fast!”

In the aftermath of Tenstorrent’s TT-Deploy event, where the company showed initial demonstrations of what its chips can do when deployed at scale, Keller told EE Times that Tenstorrent can beat the performance of both GPUs and more specialized AI hardware with its BlackHole Galaxy server.

Keller believes AI inference is ultimately a networking and memory problem, and that Tenstorrent’s architecture is now proving that at scale.

At TT-Deploy, the company demonstrated performance across a range of workloads. For example, 16 Tenstorrent Galaxy servers (512 chips) can inference DeepSeek-671B at up to 350 tokens per second per user at batch 32.
