In February 2026, Tenstorrent, an AI chip company, executed a firmware update that reduced the core count of its Blackhole p150 AI acceleration card from 140 to 120. This led to a roughly 14% drop in its theoretical peak computing capacity. The company justified this action by asserting that it was intended to standardize the interface. Moreover, they maintained that under normal workloads, the actual performance degradation would merely range from 1% to 2%.
