With $720M round, Britain's Fractile gets a leg up in the race for AI chips | TechCrunch
获7.2亿美元融资，英国Fractile在AI芯片竞赛中占得先机 | TechCrunch
Fractile's $720M round makes it one of the best-funded AI-chip challengers, but investors are betting that purpose-built silicon can beat Nvidia on cost and power rather than just speed.
Judgment
Walter Goodwin’s next call is how to spend Fractile’s $720 million: push the DRAM-stacked chip and compiler into first shipments next year, or slow down to de-risk a design priced at over £5 billion.
Basis
The British government said the Sovereign AI Fund backed the $720 million Series C to ensure the U.K. has a greater stake in hardware underpinning its future economy. CEO Walter Goodwin wrote on LinkedIn that “there is still a lot of work ahead” and the funding will let Fractile “ship [its] first chips and systems next year.” The round was led by Thrive Capital, Founders Fund, Lightspeed Venture Partners, and Redpoint; the government put valuation at “over £5 billion,” while FT and a Reuters source reported about $7 billion. Mechanically, Fractile’s pivot centers on stacking DRAM on top of each chip to bypass the usual memory-capacity trade-off, with a machine-learning compiler to speed LLM execution; agentic AI’s longer task chains make that trade-off harder.
Unclear The source does not give Fractile’s cost, power, or performance benchmarks against Nvidia, nor named customers for the first chips and systems.
