The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
Yahoo Finance reported the launch on July 23, 2026.
AMD's[3] Helios product page gives each MI455X "432 GB HBM4" and "up to 40 PFLOPS FP4", and the Venice CPU "up to 256 high performance cores" on Zen 6.
AMD's[2] own launch blog gives the rack as 72 MI455X GPUs with "2.9 exaflops of dense FP4 compute, 1.4 exaflops of FP8 compute, 31 TB of HBM4" and claims up to 15% more AI compute and 50% more HBM capacity than a Vera Rubin NVL72 rack.

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
