However, despite the technical preparation, the chip will not go to production until 2026. Initially, it was planned to be released in 2023, but the project was faced with many delays.
The Rhea1 was built according to the TSMC N6 processing process, 80 branches include nuclear nuclear yader, 64 GB HBMM2E memory and DDR5 interface. Although the features have progressed at the beginning of development, they may have outdated against the background of the progress in the sector when released.
The project was also accompanied by frequent revision of configuration between 64 to 80 cores that slowed down development.
Despite my delay, Rhea1 continues to be an important element of technological sovereignty strategy in Europe. With Nvidia Grace Hopper accelerators, the GPU section will be the central processor of Jupiter Supercomputer, which is already 80% ready.
It is expected to fully commissioning until the end of 2026. Meanwhile, Spearl is already working on the next chip – Rhea2.
