Fujitsu is already working on a successor to the ARM-based data center chip that also powers the supercomputer Fugaku.
Fujitsu is working on a successor to the A64FX. This chip forms the basis of Fugaku: currently the second most powerful supercomputer in the world. Fugaku contains approximately 150,000 A54FX processors, showing that the ARM architecture is in no way inferior to alternatives at the ultimate high-end of the computing spectrum. Fujitsu has further commercialized the chip in two HPC systems: PrimeHPC FX1000 and FX700. With Apollo 80, HPE has also launched an HPC platform based around the ARM processor.
In other words, Fujitsu can call the chip a success. So it’s no wonder that a sequel is planned. Details are scarce, although The Register now knows that the next version of the chip is planned for 2027. The code name of the new chip is Monaka. Fujitsu would not only focus on the HPC market with Monaka, but also has broader AI and analytics workloads in mind.
Efficiency Champion
Additionally, raw performance is not the only consideration when designing the chip. Fujitsu wants to offer “overwhelming energy efficiency” compared to alternatives that will be on the market by 2027. In other words, Monaka needs to become the power-to-watt ratio champion.
Fujitsu is not only working on the new processor. The Japanese government is also interested. Finally, the development takes place under the roof of the research institute New energy and industrial technology development organization (NEDO). NEDO wants data centers to be at least 40 percent more energy efficient by 2030 than they are today, and Monaka seems to fit that picture.
