The press release is devoid of useful information, unsurprisingly. You can run an LLM under almost any energy envelope if you’re willing to wait long enough for the result. Total energy consumed and the time difference are the more important metrics.

The actual paper is here: https://arxiv.org/abs/2406.02528

The key part from the summary:

> To properly quantify the efficiency of our architecture, we build a custom hardware solution on an FPGA which exploits lightweight operations beyond what GPUs are capable of. We processed billion-parameter scale models at 13W beyond human readable throughput, moving LLMs closer to brain-like efficiency.

There is a lot of unnecessary obfuscation of the numbers going on in the abstract as well, which is unfortunate. Instead of quoting the numbers they call it “billion-parameter scale” and “beyond human readable throughout”.
