In 2023, the claim was that LPO could cut power by 50% by eliminating the DSP. Now it’s 67%? There’s not a lot of field data obviously. Was there any explanation? Great extrapolation on the explosion of beachfront real estate.

In reply to Calamity Jim. I'm bookmarking this page now; will check back in 2028, 2036, and 2039 (for sure!)! 8^b

In reply to Hubert. Oh well, I'm with you I think, seeing how it took 11 years to go from TF to PF (97-08), and 14 years from PF to EF (08-22), one can imagine 17+ years to ZF (2039+), with 200 EF in-between somewhere, maybe 2036. You deserve that $16-$20 billion net worth IMHO ... eh-eh-eh!

An interesting Hot Interconnects keynote by Andy Bechtolsheim, with insightful, provocative, and optimistic bits. A more ocnservative analysis might estimate that performance increases by 2x in 2 years (4x in 4 years), and power consumption goes up by 2x in 4 years, so that power efficiency goes up by 2x in 4 years as well (based on 3.3x perf in 3 years from A100 to H100, with 1.75x TDP (3x in 6y), and 2x perf in 2 years from MI250x to MI300x, with 1.5x TDP (2x in 4y)).

So, possibly 12 years (2036, conservative) to the 64x perf Z100, at around 5 kW, and 100x perf with liquid cooling … which is still WoW! That’ll be 200 ExaFlops of FP64 HPC, or 2 ZettaFlops in MxP, all at approx 200 MW (save some major improvement in efficiency) … with all calculation errors mine, of course.

The cost and power advantages of LPO should clearly remain.
