ASUS Chromebook CX15 (CX1505CTA)

The ASUS Chromebook CX15 (CX1505CTA) is a big-screen ChromeOS laptop for browsing, schoolwork, and video at home, built for one task at a time rather than heavy multitasking. It is the newer version of the Celeron N4500 CX15 in the same chassis, now with Intel’s dual-core Processor N50, a second USB-C port, and no microSD slot. Google supports it with updates through June 2033. The memory is soldered, so buy the 8GB build for anything past light use.

Ports, screen, and build

All of the ports sit on the left edge: two USB 3.2 Gen 1 Type-C ports with DisplayPort output and Power Delivery, one USB 3.2 Gen 1 Type-A port, an HDMI 1.4 output, and a 3.5mm combo audio jack. The right edge carries only a Kensington lock slot. Two USB-C ports mean the charger, an external display, and a USB-A accessory can all stay connected without a hub. HDMI 1.4 drives a 1080p TV or projector but is not meant for a 4K or high-refresh monitor.

ASUS lists WiFi 6 (802.11ax, dual band 2x2) and Bluetooth 5.4. The 15.6-inch 1920x1080 panel is non-touch with an anti-glare finish, rated at 300 nits and 45% NTSC color. The 42Wh three-cell battery charges over USB-C from the included 45W adapter, and ASUS rates it at up to 13 hours on the 4GB model.

The keyboard is a chiclet layout with 1.35mm of key travel, a spill-resistant design, and a numeric keypad on the right, with no backlight. The plastic chassis is rated to MIL-STD 810H, measures about 14.2 by 9.1 by 0.8 inches, and starts at 3.5 pounds. The 720p webcam has a physical privacy shutter, and the board carries a Titan C security chip.

Intel N50 performance and the two memory sizes

The Intel Processor N50 has two efficiency cores and two threads, a 3.4 GHz boost clock, 6MB of cache, and a 6W power rating. Intel launched it in early 2023, and its PassMark CPU Mark of about 2,600 is roughly 45% above the Celeron N4500 in the older CX15, about half of an Intel N150, and about a quarter of the Core 3 N355 in the Chromebook Plus CX15. It handles web browsing, Google Docs, streaming, and video calls when only a few tabs are open at once.

The 4GB model has very little room once ChromeOS, a handful of tabs, and an Android app are running. The 8GB model (CX1505CTA-AS88F-PG) keeps more tabs in memory, though it does not change the two-core processor. The 128GB of eMMC storage is soldered too, and with no microSD slot, extra space comes from a USB drive or cloud storage.

The N50 and the 720p webcam both fall short of the Chromebook Plus requirements, so neither configuration gets that tier’s on-device AI features. Its June 2033 update date is two years past the N4500 CX15’s June 2031 and two years before the Plus model’s June 2035, and the auto-update expiration date marks when security patches stop.

Reviewer Insights

Chrome Unboxed

Chrome Unboxed unboxed the 4GB/128GB model in purple after ASUS offered it a unit, and Robby Payne wrote up the same model in an unboxing article. In the video, the host said “The keyboard actually feels really good,” quiet but with a good click and no mistyping, and found the numeric keypad a little small but wide enough to type on by feel. He called the touchpad smaller than most on 15-inch laptops but usable, and said “I do just really like the build quality here for an all plastic device.” Payne’s article said the plastic chassis “doesn’t feel cheap or flimsy in hand.”

On the screen, the host noted that 300 nits is not bright but that the anti-glare coating worked, text looked sharp, and scrolling was smooth, and he said “I like the screen a lot.” He found the speakers better than those on many cheap Chromebooks, with a little mid and low end and no real bass. The 720p webcam was a little grainy but adjusted well when he pointed it at a dark background.

He expected the 4GB of memory to hurt alongside the two-core processor, and with three tabs open and Android apps turned off he noticed some stuttering, though he said the studio’s slow internet may have played a part and that loaded pages scrolled and zoomed smoothly. He said the N50 is not meant for 20 tabs or several virtual desks, and that it suits a single task with a couple of web pages open: checking social media, banking, simple spreadsheets, and video calls. Payne wrote that the N50 “handles daily web tasks, Google Docs editing, video streaming, and casual web navigation far better than I expected,” but he would not recommend it for people who juggle many tabs, web apps, and Android apps. Battery life was not measured; the host guessed 10 to 12 hours from the 6W chip.

Who it’s for

The CX15 (CX1505CTA) fits browsing, schoolwork, streaming, banking, simple spreadsheets, and video calls with a couple of pages open, the single-task use Chrome Unboxed described. The 15.6-inch anti-glare 1080p screen, the numeric keypad, HDMI plus two USB-C ports, and updates through June 2033 suit a desk at home. Buy the 8GB build, because the soldered 4GB leaves little room once a few tabs and an Android app are running.

Skip it if you keep many tabs open, use several virtual desks, or lean on Android or Linux apps. The ASUS Chromebook CM15 (CM1505) uses the same chassis with a MediaTek Kompanio 540, an ARM chip with about twice the N50’s PassMark score, and Google supports it through June 2036, though it runs only ARM builds of Linux software. The Chromebook Plus CX15 is the step up for heavy tabs, Android apps, or Linux tools. The Chromebook comparison chart lines these models up spec by spec.
