Meteor Lake is aging out of Intel's lineup as 18A-based Panther Lake ramps through 2026, which leaves open the question of what fills Intel 4 capacity next. A multi-generation firewall ASIC program is a reasonable answer with mature yields, a customer that values supply stability over bleeding-edge density, and a part Intel described as tailored for cost-sensitive applications. Intel said in April that yields were improving across Intel 4, Intel 3, and 18A.
Fortinet's 2025 annual report names Renesas and Toshiba America as the contract manufacturers for its ASICs, utilizing foundries in Taiwan and Japan operated either by TSMC or by the contract manufacturers themselves. The current SP5, a monolithic 7nm Arm-based SoC announced in February 2023, sits in that supply chain, so SP6 on Intel 4 moves Fortinet's next flagship security processor out of a TSMC-linked flow and into Intel's. The disaggregated design language in the announcement points to a chiplet-based part, a first for Fortinet's SP line.
Fortinet re-engineered three FortiGate models in 2022, the 70F, 600F, and 3700F, to accept alternative components during the chip shortage, and CMO John Maddison told SDxCentral at the time that the company wouldn't wait for parts to arrive in 2023. The "resilient and diversified" supply chain used in the SP6 press tracks back to that experience. Ken Xie called Fortinet "the #1 firewall leader with a 55% unit market share" in the company's 2025 results in February, with approximately six million FortiGates deployed, so there’s real, substantial volume here even if the parts are relatively inexpensive.
CEO Lip-Bu Tan told CNBC in May that he expected commitments from multiple foundry customers in the second half of 2026, and Intel told investors in January that two prospective customers were evaluating 14A test chips . The SP6 announcement comes inside Tan's stated window, and it finally gives Intel something its foundry marketing has lacked in a named customer with shipping volume on a node with mature yields. Meanwhile, an 18A or 14A commitment from a major external customer is still missing, and Fortinet's cost-sensitive parts on a 2023 node don't substitute for one.
