Apple tests an M3 chip with 12 CPU and 18 GPU cores, and 36GB of RAM; Meta shows its Apple Watch feelings by pulling Messenger and launching WhatsApp for WearOS
As Apple prepares to launch its next M2 Macs, the company is already ramping up testing of M3 chips.
Context & Ripple Effects
Apple was already using broad pre-release hardware testing to map its Mac roadmap, including M2-based chips across at least nine Mac models. This report shows M3 validation beginning while the next M2 Macs were still being prepared, indicating overlapping chip and product cycles rather than a clean handoff.
The configuration also became an early marker for a wider M3 family: later developer logs pointed to a higher-end M3 Max configuration with substantially more CPU, GPU and memory capacity. Separately, Meta’s app decisions make messaging availability a point of distinction between Apple Watch and WearOS.
First-order effects
- Apple can validate an M3 configuration with 12 CPU cores, 18 GPU cores and 36GB of memory while continuing its near-term M2 Mac launch plans.
- Apple Watch users lose Messenger access, while WearOS users gain a native WhatsApp option from Meta.
Second-order effects
- Overlapping M2 and M3 work lets Apple maintain a steadier Mac refresh pipeline, while giving software developers another forthcoming hardware configuration to account for.
- Meta’s split distribution changes the relative messaging proposition of the two watch platforms: WearOS gains WhatsApp as Apple Watch loses Messenger.
Third-order effects
- If Apple continues parallel validation across chip generations and performance tiers, its in-house silicon roadmap can support more frequent and more segmented Mac product updates.
- If major communication services keep choosing different wearable platforms for launch or withdrawal, app availability—not hardware alone—will increasingly shape smartwatch platform competition.
The trend: This is one data point in the convergence of vertically integrated silicon roadmaps and platform-specific app distribution as key levers of device differentiation.
