Are the tenstorrent blackhole cards anyhow competitive?

They seem to be showing very decent performance results for diffusion transformers. Not so much for the autoregressive transformers (the "regular" ones).

A test [1] by a random dude with the older Wormhole N150 delivers half the performance (as in tokens/s) of a RTX 4090 in generic Llama tests. The new p150 should have double the performance according to specs, but who knows. I'd call it somewhat competitive.

Tenstorrent's Wormhole was garbage for anything other than development.

Blackhole is actually usable. They cost slightly more than a used 3090 Ti with 24 GB VRAM, but they come with 32GB GDDR6 and 4x 800G networking (apparently only blackholes to other blackholes).

Nvidia's datacenter GPUs are at least 4x faster, but they also cost 20 times as much. There's also the fact that they have as much SRAM as Groq LPUs.

There is also another present. You get 16 Ascalon cores per Blackhole card. Yes, you've heard that right. You are getting 16 of the fastest RISC-V cores ever developed for a measily $999 to $1,299.

My only complaint is that they have these insane 300W TDPs.
