Ex-Apple engineer launches Chinese rival to Apple's Vision Pro

GravityXR, a Chinese startup founded by former Apple engineer Wang Chaohao, has introduced the Jizhi G-X100, an all-in-one mixed reality (MR) chip for XR headsets and AI glasses.

The company claims the chip achieves a photon-to-photon latency of 9 milliseconds, faster than Apple’s Vision Pro at 12 milliseconds.

The G-X100 uses a 5-nanometer node and targets lightweight AI glasses and advanced XR headsets.

GravityXR also revealed two additional chips: one for high-definition video recording in AR glasses and another focused on energy-efficient spatial computing.

The startup is backed by HongShan, Gaorong Capital, Goertek, and miHoYo, with clients reportedly including Meta, Goertek, and Agibot.

🧠 Food for thought

Implications, context, and why it matters.

China’s Mixed Reality (MR) chip debut faces unclear manufacturing and OpenXR adoption hurdles

GravityXR touts 9 ms latency, yet the announcement leaves out production basics 1. No fabrication partner, tapeout status (final chip design handoff to the foundry), yield rates or delivery timelines appear 1. TSMC 5-nanometer (nm) lines are projected to be fully booked in 2026 due to Apple, NVIDIA, AMD and Qualcomm demand in mobile and high performance computing (HPC) 2.
OpenXR compatibility remains unconfirmed 3. Without OpenXR runtime support, developers must ship device-specific code 4. That would curb the G-X100’s appeal with original equipment manufacturers (OEMs) using standardized workflows 4. A news article claims clients like Meta, Goertek, Agibot, yet sources 1 and 5 do not list clients or mention OpenXR runtime support.

Middleware providers could benefit if GravityXR’s developer ecosystem trails established platforms

If GravityXR’s software development kit (SDK) lacks a mature OpenXR runtime, the on-device system software for the cross-platform standard that speeds development with a single application programming interface (API) across extended reality (XR) devices, or Unity and Unreal Engine integration, middleware can step in with compatibility layers 6 7 3. Developers need tools to port apps from existing OpenXR platforms to G-X100 without rewriting core logic 3.
Goertek, Agibot on the stated client list hint at design wins in augmented reality (AR) glasses for Western XR suppliers plus tooling firms. Partnerships offering local developer support, OpenXR conformance testing (verification that an implementation meets the standard) and graphics API tuning could make these vendors essential if the G-X100 sees adoption 3.
