Detailed Insights into the ASUS Chromebook Plus CX15
The ASUS Chromebook Plus CX15 measures 14.15 x 9.14 x 0.79 inches and weighs 3.51 pounds, making it reasonably portable for a 15.6-inch notebook. The chassis is constructed entirely from plastic, which keeps weight down but results in a build that feels somewhat budget-oriented. The lid has a unique texture that ASUS describes as rock grey, and while functional, it does feel distinctly plasticky compared to aluminum-bodied competitors. A physical webcam privacy slider sits above the Full HD camera, though reviewers note it can be somewhat difficult to operate.
At the heart of the CX15 lies the Intel Core 3 N355 processor, part of Intel’s Twin Lake family. This 8-core chip runs at a base frequency of 1.7GHz and can boost up to 3.8GHz when needed. With a PassMark score around 10,476, it handles everyday Chromebook tasks like web browsing, document editing, and video streaming with ease. The processor represents a modest upgrade over previous Alder Lake-N chips while bringing the critical benefit of extended platform support through 2035.
Connectivity options include WiFi 6E wireless networking and Bluetooth 5.3 for modern peripheral support. The port selection provides two USB-C 3.2 Gen 1 ports with DisplayPort output and power delivery, one USB-A 3.2 Gen 1 port, and full-size HDMI 1.4B output. The absence of a microSD card reader may disappoint some users, but the USB port selection covers most common connectivity needs. Storage relies on eMMC rather than faster NVMe SSDs, which keeps costs down but results in noticeably slower read and write speeds compared to premium Chromebooks.
Reviewer Insights on the ASUS Chromebook Plus CX15
Chrome Unboxed Hands-On
Chrome Unboxed provided an early hands-on look at the 2025 ASUS Chromebook Plus CX15, focusing on the new Twin Lake processor and build quality observations. They noted that “This is one of the first new Chromebook Plus models to feature the Intel Twin Lake Core 3 N355 processor” and highlighted the exceptional software support timeline.
The reviewer was impressed by the redesigned keyboard layout featuring the new Quick Insert key, which provides quick access to AI-powered suggestions and clipboard history. The backlit keyboard offers adjustable brightness levels and the addition of a full number pad makes this a practical choice for data entry tasks. However, they expressed concerns about the touchpad, stating “it just feels a bit hollow, a little bit more on the cheap side.”
The screen delivers a 15.6-inch Full HD IPS panel with anti-glare coating, which performs adequately for everyday use but shows its budget positioning with only 45% NTSC color coverage. Chrome Unboxed noted the 180-degree hinge allows the screen to lay completely flat, useful for collaboration scenarios. Overall, their assessment positioned this as a solid entry-to-mid-range Chromebook that prioritizes longevity and AI features over premium build materials.
Conclusion
The ASUS Chromebook Plus CX15 (CX1505) makes its strongest argument through exceptional longevity, offering Chrome OS updates through June 2035 thanks to the new Intel Twin Lake platform. Combined with Chromebook Plus certification and its AI-powered features, this makes it an attractive option for users who plan to keep their laptop for years rather than upgrading frequently. The full-size keyboard with number pad and reasonable 15.6-inch display size suit it well for productivity-focused work.
That said, users who prioritize premium build quality should look elsewhere. The plastic construction, hollow-feeling touchpad, and eMMC storage position this firmly in the entry-to-mid-range segment despite the Chromebook Plus branding. Those who need faster storage performance or better display color accuracy might want to consider alternatives like the Acer Chromebook Plus 516 GE or HP Chromebook Plus x360 14.
