Tenstorrent in talks with TSMC, Samsung, even Rapidus, for 2nm; Jim Keller considering working with Intel

AI chip design startup, Tenstorrent, has announced it's working with a range of companies to build out its next-generation AI chips. These include TSMC, Samsung, and Japanese firm Rapidus, all of which will provide their latest 2nm process nodes to develop future AI hardware. CEO and AMD and Apple Veteran, Jim Keller, has also said he'd consider working with Intel, but that it "still [has] a lot of work to do," according to Nikkei Asia.

Tenstorrent was founded in 2016, with Jim Keller coming on as CTO in 2020 and then CEO in 2023. It's targeting a different approach to giants like Nvidia in its chip production, focusing more on cutting costs and maximizing efficiency. Its current chips, like the Blackhole AI accelerator, are built on TSMC's 6nm node, while an upcoming Quasar chip design uses Samsung's 4nm process. Beyond that, it wants 2nm for whatever comes next.

It's rare for companies to work with such a range of manufacturers for cutting-edge chips, but Tenstorrent claims it can do it because it uses chiplets for its designs. That lets it have different fabricators build different chips for it, and then it can package them altogether on a single die.

Alongside TSMC and Samsung, it is also working with Japanese firm Rapidus, a startup set up in just 2022 and supported by a range of Japanese businesses. Its sole model is to produce cutting-edge 2nm hardware by 2027. This is partly to reinvigorate Japan's semiconductor industry, but also to create localized and national capacity for advanced semiconductor production, as many countries are looking to do following the AI boom.

Tenstorrent has also worked with GlobalFoundries in the past, and has said it won't rule out using Intel's process technology in the future. Keller just seemingly wants to see where that technology goes, especially following recent investments from Nvidia and the US government.

Speaking on Intel with Nikkei Asia, Jelly said that "they still have a lot of work to do ... to deliver a really solid technology roadmap."

More immediately, Keller is looking to undercut the competition and target smaller companies that want to still leverage the capabilities of locally run AI, not just those building out giant multi-billion-dollar data centers.

"Everybody says Nvidia, OpenAI, Google ... Well, the long tail of small applications is very large, too," Keller said. "We have developers who buy a $10,000 workstation and they're really happy. ... There's a lot of them, and that will lead to bigger business."

What does it say about Intel Foundry that Jim Keller is working with Rapidus but has declined to work with Intel at the moment?

This is interesting news because Tenstorrent was one of the Rapidus 2nm clients announced or mentioned between 2023 and 2024. Now, suddenly, Tenstorrent is looking for 2nm foundries beyond Rapidus.

There are several possible explanations:
  1. 1. Tenstorrent has additional needs, such as features, quantity, capacity, pricing, or schedule, that Rapidus cannot meet.

  2. 2. Tenstorrent’s product roadmap cannot be supported by Rapidus.

  3. 3. Rapidus’s 2nm development or deployment is encountering difficulties.

  4. 4. Rapidus is facing challenges such as raising additional capital or acquiring expensive equipment.
 
Intel's PDK are still a mess. Even if 18A is great node no one will be able to make anything on it without expertise on the PDK.
In your opinion, why is Rapidus able to make a better PDK than Intel despite the fact that Rapidus is a much smaller company? Is it an issue of talent or is Intel saddled with too many bad legacy practices?

With 18A it's priorities they are focusing on their products and revenue stream there is no grounds up PDK for external till 14A as gor legacy practices many legacy practices are removed.
 
I thought they already signed with Rapidus over a year ago. "we are looking at everyone" seems strange

Does Tenstorrent have any chips being sold today or in 2026? What revenue are people expecting from them.

Tenstorrent is 10 years old, has raised more than $1B and current revenue cannot even cover the 1k employee burn rate. What position are they in to negotiate a wafer agreement with one foundry much less four? Jim Keller is also a former Intel and Tesla employee not just Apple and AMD. This is his first CEO job and probably his last. CTOs do not necessarily make good CEOs.
 
Keller's company has huge backing from Jeff Bezos so I doubt they will go under.

Samsung is another one of Tenstorrent's backers so they can always get to use their fabs I think.

I suspect Rapidus was initially selected because they promised delivery of silicon faster than their competitors. But I doubt they can provide the necessary volume.

Also, Jim Keller only joined the company 4 years ago. Initially as CTO and was only made CEO 2 years later. They released three hardware processor products since and their latest Blackhole processor seems to be price performance competitive with NVIDIA for AI.
