That "peak" was the average NPS for a single move. They could hit 1B for a second, 200M for 4 seconds, and get roughly 350M for the average for that 5 seconds. Remember, DB didn't count any "real peak" number... because it didn't count nodes at all in the hardware. Numbers are just guestimates based on duty-cycle of the chess processors times their speed, summed up. > >-- >GCP
