MetaX C700

MetaX C700, or Xiyun C700, is the third generation of MetaX's combined training and inference GPU line and the successor to the C600. MetaX disclosed it in the signed reply to the first round of review inquiries on its Shanghai STAR Market IPO application, published on 27 August 2025, where it appears as one of the four projects the company raised money to fund, with a total budgeted investment of 2.04 billion yuan. The company positions it as the future flagship of its fully domestic supply chain and says its performance approaches NVIDIA's H100, a claim it repeats three times without ever attaching a number, a precision or a metric to it. The one concrete capability MetaX singles out is compute support for low precisions including FP4, which matters because it is the clearest technical break from the C600: that part's instruction set gained FP4 conversion instructions only, while the C700 is credited with FP4 arithmetic itself. MetaX also states that the C700 adopts a new generation of its GPU architecture and instruction set, that it is built on a more advanced node of domestic process technology than the C600, and that it carries ultra-high-bandwidth memory, but it names no architecture, no foundry, no node and no memory generation. The purchased-intellectual-property schedule for the project is the only structural evidence available and it points to a high-bandwidth memory interface, a PCIe host interface and, newly for this generation, a UCIe die-to-die interface for chiplet integration that the C600 project did not buy. Development status is the important caveat: as of MetaX's most recent disclosure the core design and functional verification were largely complete and physical implementation was still being optimised, so the chip had not taped out, and every other unreleased part in this database is at least past that milestone. MetaX's shift to an entirely domestic supply chain for the C600 and C700 was not a preference but a consequence of United States restrictions that in November 2024 stopped it placing foundry orders for the C500 series. No throughput figure at any precision has ever been published for the C700, including for the FP4 capability MetaX highlights, and an analyst report published eleven months later by a brokerage with company access restates the filing's wording verbatim while adding no numbers of its own.
