With a massive 1.5x performance jump over current Chromebook Plus models, this convertible is shaping up to be a premium powerhouse.
We finally have our first real look at the performance of the highly anticipated "Moonstone" Googlebook from Acer, thanks to new Geekbench listings. Derived from the "Fatcat" reference board featuring Intel Panther Lake (Core Ultra Series 3) processors, Moonstone has been in development since the fall of 2025. Now, these newly surfaced benchmarks are corroborating some of its most exciting spec configurations.
Two configurations, serious power
Data registered on Geekbench under the name "Quanta Moonstone" confirms the existence of two distinct CPU and RAM configurations.
Here is how the average benchmark scores break down:
| CPU / RAM Configuration | Single-Core Average | Multi-Core Average |
| Core Ultra 5 325 / 16GB | ~ 2,420 | ~ 9,110 |
| Core Ultra 7 355 / 32GB | ~ 2,500 | ~ 9,580 |
While the raw score difference between the two Panther Lake processors is relatively narrow, the generational leap is undeniable. When compared to the Core Ultra 5 115U (Series 2) powering current high-end Chromebook Plus devices, Moonstone delivers roughly a 1.5x performance boost across the board. That is a massive, tangible upgrade for everyday performance.
Interestingly, the test environment lists the operating system as "Android 16." Given that Lenovo's sibling device, "Ruby" (which also belongs to the Fatcat family), was previously benchmarked running Android 17, it is highly likely that this Moonstone data was captured in an early build environment rather than on final software.
A premium convertible with wide appeal
Built on the "Kinmen" convertible design foundation, Moonstone isn't just about CPU upgrades. The confirmation of a top-tier SKU packing a massive 32GB of RAM—alongside the standard 16GB model—signals that Acer is taking multitasking seriously.
By offering these two distinct tiers, Acer is positioning Moonstone to cover a much wider range of price points and user needs within the high-end Googlebook market, ensuring it appeals to both mainstream power users and demanding professionals looking for a premium device.
