Jim Keller's Tenstorrent is downgrading Blackhole p150 cards from 140 to 120 tensor cores via firmware update — will ship cards with 120 tensor cores going forward, company claims existing users should expect 1-2% performance drop

Tenstorrent, led by Jim Keller, is reducing the number of tensor cores on its Blackhole p150 cards from 140 to 120 through a firmware update, affecting both existing and new units. The company claims that users should expect a minor 1-2% performance drop due to this change. The reason behind this downgrade remains unclear, leaving customers puzzled. Despite the reduction in tensor cores, Tenstorrent asserts that the impact on performance should be minimal, especially for single-card setups. The company's move has sparked discussions among users about the utilization of the hardware and potential effects on existing code.
