144 ARM cores with 3.5D chiplet design: This is the Fujitsu Monaka processor

Fujistu has revealed some details of its “Monaka” high-performance data center and processing processor with 144 Armv9-A architecture cores.

Monaka will be manufactured with a chiplet design, that is, with several blocks or “tiles” that form the processor and that are integrated with a striking “3.5D” distribution.

In the case of Monaka, have a large input/output chiplet that will be manufactured 5 nanometers and placed in the central part of the chip on the interposer. It is surrounded by four SRAM memory chiplets (it does not use HBM) manufactured at 5 nanometers and, just above each of these memory chiplets, we find other chiplets with ARM cores.

Each of these chiplets offers 36 cores and is manufactured at 2 nanometers, which gives us a total of 144 cores in a single processor.

The manufacturing of the Fujitsu Monaka will be carried out at TSMC, with its N5 and N2 processes. It will offer support for DDR5 memory, CXL 3.0 and also PCI Express 6.0.

There is still time for its arrival on the market, since it is expected that we can see it in servers for AI and high-performance computing tasks during the year 2027.
