SiFive, a company focused on open-source chip design, has raised $400 million in a funding round that values it at $3.65 billion, with Nvidia as one of the key investors. The company’s RISC-V chip designs are gaining traction in AI data centers, positioning SiFive as a competitor to traditional CPU manufacturers like Intel and AMD. Unlike proprietary systems, SiFive’s open architecture allows for greater customization and adaptability in varied applications, particularly in partnership with Nvidia’s AI technologies.

📌 Key Insights
Here are three key insights from the article about SiFive:
-
Significant Investment and Valuation: SiFive has raised $400 million in an oversubscribed funding round, resulting in a company valuation of $3.65 billion. This round featured prominent investors, including Nvidia, which highlights growing interest and confidence in SiFive’s technology.
-
RISC-V Open Chip Design: SiFive differentiates itself by using the RISC-V architecture, an open-source chip design that contrasts with the proprietary designs of Intel’s x86 and ARM. This positions SiFive well for flexibility and innovation in the growing AI data center market.
- Strategic Shift Towards AI Data Centers: With the support of Nvidia and the new funding, SiFive aims to transition from its traditional embedded systems market to designing CPUs specifically tailored for AI data centers, compatible with Nvidia’s CUDA and NVLink Fusion systems. This move positions SiFive as a key player in the competitive landscape of AI and high-performance computing.

SiFive, a company founded in 2015 by the UC Berkeley engineers who created an open source chip design, has landed a $400 million oversubscribed round that values the company at $3.65 billion.
This deal is interesting for a bunch of reasons. For one, SiFive’s RISC-V open chip design is based on the RISC processor, not Intel’s x86 or ARM, the two major types of CPUs that currently feed Nvidia’s GPU computer system AI empire.
Also, Nvidia was investor in this round, alongside a long list of VCs, private equity, and hedge funds. The round was led by Atreides Management, founded by former Fidelity investor bigwig Gavin Baker. (Atreides was also an investor in Cerebras Systems $1 billion round). Other investors in the round include Apollo Global Management, D1 Capital Partners, Point72 Turion, T. Rowe Price Sutter Hill Ventures, and others.
SiFive’s business model is like Arm’s was in years gone by — it licenses its chip designs to those who modify them for their own needs and does not sell the chips themselves. (In March, Arm changed its model when it launched the first-ever chip it manufactured, an AI chip, developed with Meta with customers including OpenAI, Cerebras, and Cloudflare.)
SiFive stands in rarified air with chip designs that are open, not proprietary, as well as neutral, not reliant on specific customers. In fact, SiFive hasn’t raised since March 2022, Pitchbook estimates, when it brought in $175 million led by Coatue Management at a pre-money valuation of $2.33 billion. Intel Capital, Qualcomm Ventures, Aramco Ventures, were part of that round.
RISC-V has been, until recently, better known as a chip for smaller uses, like embedded systems. But with this cash and Nvidia’s attention, SiFive is moving into CPUs for AI data centers. SiFive’s designs will work with Nvidia’s CUDA software and its NVLink Fusion, a rack server system that lets different CPUs plug into Nvidia’s “AI factory.”
In other words, as rivals Intel and AMD seek to compete with Nvidia’s GPU, Nvidia is backing an 11-year-old startup that can design CPUs on an open and completely alternate technology.
