SiPearl delivers first Rhea1 CPU samples to Bull for JUPITER supercomputer

SiPearl delivered the first Rhea1 CPU samples to Bull for integration into JUPITER, Europe's exascale flagship; SiPearl calls it its first order and first significant revenue. General availability of the 80 core Arm based chip is still due by end 2026.

What it does not test. This does not establish volume production of Rhea1 or that JUPITER's node count runs mainly on European rather than AMD silicon.

How this item counts. Towards autonomy: it changes who made the parts. Binding 3 of 3 (in force or operating), scale 1 of 3 (small), Verified counts in full: weight +3 of 36 possible. European Rhea1 chip samples delivered for JUPITER; parts moves, but only samples not volume. European Sovereignty Index
