It's Arm based, although they barely mention that.
thebeardisred•1h ago
Thanks I was, of course, looking and very curious what their tool chain story will be.
minimeow•1h ago
Yes the lack of transparency on ARM architecture and the obfuscation of the RAM capacity with just the slot information is annoying. Not sure if it is deliberate to sell this at a premium to "mainframe" customers or whether its just their marketing folk not being on the ball. Fascinated by the fact Japan has a 2nm process node but I suspect that too is marketing. Perhaps the 2nm portion of the chip is done at TSMC and the rest of the package done in Japan or something like that. It's not like there's a plethora of 2nm Fabs around the planet to choose from.
imtringued•26m ago
It looks to me like it is an AI optimized HPC CPU and while HPC CPUs are actually quite fast, they are not particularly well suited for transformer based neural networks.

It's weird that they don't give out any of the interesting numbers like number of memory channels, how much SRAM they have (CPUs tend to have more of it) or what their expected performance is going to be.

nubinetwork•48m ago
If they didn't mention SVE2, I wouldn't have known either... that would make it arm9 at the earliest...
a012•18m ago
Quick Google result is it’s basically a Neoverse V2 system, so yeah, armv9.

Edit: it’s funny because this article from 2021 mentioned Fujisu precisely https://siliconangle.com/2021/03/30/arm-unveils-armv9-archit...

titzer•35m ago
They actually do not in that article. I had to look elsewhere to find that out. Weird, one would expect that a big announcement like this would probably need to be vetted against licensing agreements with Arm that would probably want that fact to be prominently highlighted in press releases.
shrubble•22m ago
Interesting to note that Fujitsu did this when the SPARC architecture was popular: they enhanced/developed a CPU for the same ABI.

Seems they have decided they don’t want to create their own architecture, but take the popular architecture and build on it.

qmarchi•5m ago
Thanks kinda how Japan works. Inventing something new is hard, but taking something that's a cool idea and making it actually usable is well within their wheelhouse.

See: - Blue LEDs - Quartz Watches - Lithium-ion Batteries - Bidets

mrweasel•17m ago
Not mentioning the architecture is rather strange. Being Fujitsu I'd expect SPARC, but apparently not. Maybe we're reaching a point where some circles either don't care or just defaults to ARM?

Obviously they can just ignore the license in the future and continue development out of a local branch, but it's also a bit disingenuous to speak of "sovereign infrastructure" and then use licensed processor design.

sherujgr•1h ago
Iam very curious as to how well it'll perform outside of Asia.
esafak•1h ago
And if they'll sell it, seeing as they market it as 'sovereign AI'.
mrweasel•15m ago
Performance would probably be the same regardless of where you run the CPU.
alightsoul•1h ago
Fun fact, Fujitsu used to run their own fabs in Japan until they were sold to UMC and now they're another UMC fab although they are stuck at like the 20nm node. So this is likely made at JASM.
iicc•1h ago
I think they'd say if the CPU was fabbed in Japan, instead there's some very "careful" wording:

>next-generation CPU, FUJITSU-MONAKA [1], designed and developed in Japan

>Fujitsu MONAKA Server, powered by the FUJITSU-MONAKA CPU, enhances sovereign capabilities through domestic manufacturing,

iicc•58m ago
>FUJITSU-MONAKA utilizes a 3D-stacked architecture with a state-of-the-art 2nm process for the core and a 5nm process for the cache and I/O sections.

https://en.wikipedia.org/wiki/Japan_Advanced_Semiconductor_M...

>The Phase 2 factory was under construction as of January 2025, next to the Phase 1 facility, and is expected to be completed by 2027.[3] Initially planned for manufacturing semiconductors using a 6 nm process, 3 nm was incorporated into production plans for 2028 in 2026

szatkus•26m ago
It's 2nm, so it has to be manufactured by TSMC.
Youden•1h ago
Where are the CPUs fabbed? They make a big deal about "sovereign" but is the CPU actually made in Japan, or do they rely on TSMC?

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

Max-q•1h ago
The article says that it’s manufactured in Japan.
ranger_danger•1h ago
where exactly does it say that? I don't consider "designed and developed in Japan" to be the same as manufactured there
bradyd•1h ago
At the very top of the article: "Achieving world-class AI inference performance through Japan-developed 2nm 3D-stacked CPU and server integrated, developed, and manufactured in Japan"
sgerenser•57m ago
"Japan-developed CPU..." plus the server itself (parts, power supplies, case, etc.) integrated, developed and manufactured in Japan. It sounds like they're weasel-wording it a bit, but I don't think the CPU itself is manufactured in Japan, only "developed."
tecleandor•51m ago
Yep. I'd say the CPU is manufactured outside, and the rest of the server in Japan.
redlewel•1h ago
Would be cool to get ahold of one of these in the US.

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.

The two made-in-Japan, premium grade, Fujitsu laptops I had to work with were by far the worse pieces of electronic I have ever used. Both exhibited identical defects: fans running continuously at maximum speed, and the batteries would completely die within hours of the devices being powered off. Windows or Linux. And don't talk about that tiny unresponsive trackpad to me. Never again.
dijit•50m ago
The Fujitsu Lifebooks were legendary for their robustness back in the day, I'm genuinely sad you had that experience.

The only fujitsu laptops I used was back in 2011- it was a budget version for on-call and it was fine..

Sounds like the fans running 100% probably contributed significantly to the issue here. If I had to guess it was likely that the C-States were disabled in BIOS somehow so the CPU clock was running at full tilt the whole time, maybe combined with a bad thermal paste job.

I'm not here to defend Fujitsu but I've had really bad experiences with basically every major laptop brand (Dell: majorly bad coil whine and especially faulty soldered RAM, HP: keys vanishing from the keyboard and very weak hinges that break all the time, Apple: The GPU unsoldering itself and the butterfly keyboard shenanigans).

I don't really know any brand with a flawless track record sadly.

Before anyone brings up Thinkpads, they're trading on a reputation that hasn't been true for over a decade. If you have fond memories of a thinkpad it's most likely that you had it from before 2016, or it's "fine", but certainly not great.

nhubbard•35m ago
I do recall that Fujitsu had a very... unique approach to exposing the Setup option in their firmware. It was just a UEFI boot entry. If that entry was removed, you couldn't get back into the firmware setup; you had to find the name of the setup EFI file and then run that from the EFI console.

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

varispeed•43m ago
I wouldn't trust that this CPU can do maths properly.
Maken•37m ago
The 'Fujitsu' that made the shitty software was a British consulting company that was acquired by Fujitsu [1] to farm public contracts. This is made by the Japanese parent company.

[1] https://en.wikipedia.org/wiki/International_Computers_Limite...

nisegami•33m ago
You're right, but the scandal is so upsetting that I personally cannot ever look at Fujitsu the same way even. Also, I think you're neglecting that a large part of why it became so bad was that Fujitsu claimed there was no issue with their software. Even if it were built by a company they acquired, the response to the developing situation was something that the parent company should have stepped in to oversee.
varispeed•44m ago
Never buy products of this dodgy company.

kittikitti•39m ago
I think what's most notable about this for me is the reduced environmental impact. The specifications list liquid-cooling as optional and it highlights the CPU as the main processor instead of a power hungry GPU. My takeaway is that the next generation of AI HPC's will focus more heavily on sustainable operations.
drob518•29m ago
One problem we’re going to have with AI hardware is coming up with a standard set of specifications that are comparable. I don’t really care about the CPU GHz and the memory bandwidth, at least not directly. What I really want to know is how many tokens per second this will deliver, but that also depends on the model. We need a standard metric for that. Perhaps we agree on a specific open weight model (e.g. GLM 5.3 Flash or Qwen vWhatever) and then measure TPS on the hardware of interest.
swiftcoder•26m ago
> I don’t really care about the CPU GHz and the memory bandwidth ... What I really want to know is how many tokens per second this will deliver

There is a fairly direct link between the two numbers. You can predict the latter from former reasonably well

michaelbuckbee•24m ago
I feel like even TPS is becoming less of a good metric as we're seeing certain models handle similar problems while burning far fewer tokens.
julius•21m ago
I always heard of GB/s as most important number ... AI told me their 8800 MT/s on 8 Byte, 12 DDR5-Channels means 845 GB/s. A Nvidia RTX 4090 has 1008 GB/s. Nvidia B200 has 8000 GB/s. Is this the right way of looking at it?
hermitShell•16m ago
You have to load the model weights into VRAM over PCI-E. So the bandwidth strongly affects time to first token.

You have to run inference on the GPU by reading and writing to VRAM. So TFLOPS of the compute matters, and bandwidth to the VRAM, and this strongly affects tokens/s

If you're doing training workloads or offloading to system RAM, it gets more complicated.

Combining info from https://news.ycombinator.com/item?id=49740907 and https://news.ycombinator.com/item?id=49740901, it seems that they're relying on TSMC for the first batch and are planning to move production to JASM once that's ready?
hobofan•49m ago
Pretty sure it's worded in a way that it applies only to the server, so it should be read as two distinct things:

- Japan-developed 2nm 3D-stacked CPU

- server integrated, developed, and manufactured in Japan

dopa42365•6m ago
Ever seen the phrase "diffused in Taiwan, assembled in Malaysia"?

> put on AI inference when they don't build the GPU?

GPU in AI world is essentially a set of specific matrix calculations that this CPU supports on hardware-level. Thought memory speed seems low.

DashAnimal•59m ago
According to a Feb press release, they're fabbed by TSMC:

> For FUJITSU-MONAKA, the 2nm semiconductors will tape out next year. Due to this, Rapidus would be unable to meet the deadline, so TSMC is handling the manufacturing.

Source: https://global.fujitsu/en-global/pr/news/2026/02/12-01?utm_s...

According to Rapidus webpage, they are explicitly starting mass production of their 2nm in 2027.

Reaching further back, the Sylistic line was mostly quite good/durable, and I still use my Stylstic ST-4110 when I need to use an old scanner or control a CNC machine on my back deck when cutting tropical hardwoods.

Really miss the transflective display and wish that there were newer devices with such technology
