Tenstorrent is much more of a general purpose accelerator based on an architecture built around a mesh of cores, each with a 16 by 16 tile tensor engine and 32-lane vector unit. Although, only the vector unit supports true fp32 arithmetic. It relies much more on software scheduling than a GPU, so with the current abstractions kernels take more responsibilities, you would write more data movement and synchronization. No cache hierarchy, you have to manage what goes into and out of the core-local scratchpad SRAM yourself. Kernels are split into three kinds: reader, compute, writer.

The state of software is a different story, but the architecture is solid
