Cool that you know the tech specs of the GroqChip! Yes, that's right, 220 MB of SRAM per chip. I think the demo where we first broke 200 tokens / sec was running on 1 GroqRack, so 64 chips. The live public demo that's currently running at 275 tokens / sec I think might be running on two GroqRacks, so 128 chips. I'm not certain of either of these figures so please don't quote me! But those are the right ball-park.
Thanks, looks like you're right and this demo is running on 9 GroqRacks (576 chips). I think we may also have an 8 rack version in progress. We've tried a variety of different configurations to improve performance, which is possible because of the high level of flexibility and configurability of our architecture and compiler tool chain.
