FugakuNEXT, the supercomputer it will be used in, also some details about the next-gen Monaka-X: https://global.fujitsu/-/media/Project/Fujitsu/Fujitsu-HQ/te...

For a single CPU: 844 GB/s memory bandwidth (12 channels of DDR5 RDIMM, 8800MT/s). 4.3-6 TFLOPS.

Basically comparable to a modern (although not top-end) GPU, so good for HPC & AI workloads. (though only 2 CPUs per node, with GPUs 4-8 is more common)

>Combined with SVE2 vector operations and software optimization,

It’s ARMv9.

Why does this matter? Markets outside the US account for about half of many US technology vendors' revenue. Who is going to speak up first?

It's not terribly popular even in Japan, since it's dry, bland, fragile and has to be assembled on the spot or it goes soggy.

Also odd how big an emphasis they put on AI inference when they don't build the GPU?

I know that for GPU's the model weights have to be transferred over the bus initially, but that only has to occur once for inference use cases, so is the Fujitsu system more about training scenarios? Or is the focus more about efficiency, as these are ARM-based cores with AI additions?

It's an overcrowded market. Far better would be to focus on semiconductor supply chain, which Japan already supplies some elements, to sell to fabs.

Because the bottleneck is the fabs. If a new 2 nm fab came online today, it would immediately sell all its capacity to 2030 no problem, without Fujitsu trying this gambit.

It's not 'sovereign', the architecture is not designed in Japan, the silicon is not fabbed in Japan. This whole thing is sideways.

And here's more technical information about this generation: https://news.ycombinator.com/item?id=49443040

I do find it odd that the 2U model has less storage capacity than the 1U on their chart. That doesn't make much sense to me.

    Fujitsu MONAKA Server will be
    made broadly available from 
    November 2026 to data center 
    operators, enterprises, and 
    the academic and HPC sectors 
    in Japan and Europe, as well 
    as to the defense sector, 
    contributing to national 
    security.

Kudos to Japan

I also liked their Primergy Servers, but never got one for a reasonable price to test it out.

Another thing was the Futro series (e.g. S930) that could be used as opnsense firewall or low budget proxmox host.

Unfortunately it was always hard to obtain the high quality stuff as a consumer and years ago they sold their mainboard section to kontron. So no new Fujitsu Mainboards for now... What a pity.

A Pentium 4 hit 3.8 GHz longer than that ago in 2004, so that's not special. And the estimated price will be $7,000-10,000, which isn't special either since that's about 10x more than it should be.

Hot take: GPUs disrupted the CPU industry to such a degree that CPUs never recovered, and like the k-shaped economy, the current status quo only serves a small fraction of customers. We can and should do better, but sadly we won't. Still, it's good that Fujitsu did this, for the competition if nothing else.

Does Fujitsu have extensive expertise in processor development? I don't remember any notable Fujitsu processors.

Although, as irusensei notes, this seems to be an ARMv9 processor.

:D

For AI infrastructure:

:(

Their software is so poor that it caused probably the biggest miscarriage of justice in history. Well that and Fujitsu staff colluding with post office executives to put innocent people in prison rather than admit there was a problem
