Acer Chromebook Plus 516 CB516 16" specifications and in-depth review

Acer Chromebook Plus 516 CB516 16"

Manufacturer: Acer

The Acer Chromebook Plus 516 CB516 is a 16″ Chromebook built around a large-format IPS display and a multi-core processor architecture that balances performance and efficiency. Weighing 1,700g and measuring 18mm thick, it occupies a practical footprint for everyday use, and its 1920x1200 resolution panel delivers a 141ppi pixel density across a generously sized screen. The system supports up to four external displays simultaneously, making it a reasonably capable choice for multi-screen setups.

Under the hood, the machine pairs 8GB of DDR5 memory running at up to 5,200MHz with 256GB of flash storage and an Intel Iris Xe Graphics 80EU integrated GPU, which clocks up to 1,250MHz in turbo mode. The CPU operates on a big.LITTLE configuration with a turbo ceiling of 4.6GHz across 12 threads, and benchmark results show a Geekbench 6 multi-core score of 7,605 alongside a PassMark result of 13,420. Connectivity includes two USB 3.2 Gen 2 Type-A ports, two USB 3.2 Gen 1 Type-C ports, one HDMI output, Wi-Fi 5 support, a 3.5mm audio jack, and stereo speakers, while the 53Wh battery rounds out the hardware profile.

Pros
  • The 16″ IPS display with a 1920x1200 resolution and 141ppi pixel density offers a taller aspect ratio that provides more vertical screen space for documents and web browsing
  • DDR5 RAM with a maximum supported capacity of 64GB and a speed ceiling of 5,200MHz gives the system meaningful headroom for memory-intensive workloads
  • The processor's big.LITTLE architecture across 12 threads, combined with a 4.6GHz turbo clock, allows the CPU to handle bursts of demanding tasks while keeping the 15W TDP in check
  • Two USB 3.2 Gen 2 Type-A ports alongside two USB 3.2 Gen 1 Type-C ports provide a practical mix of connectivity options without requiring adapters for common peripherals
  • Support for up to four simultaneous displays extends the machine's utility well beyond its built-in screen for multi-monitor setups
  • The Iris Xe Graphics 80EU with 80 execution units, OpenCL 3, and OpenGL 4.6 support handles a reasonable range of graphical workloads for an integrated solution
Cons
  • At 1,700g and 18mm thick, the chassis is on the heavier and bulkier side for a portable device
  • The display runs at only 60Hz with no anti-reflection coating and no touch support, limiting its appeal for users who work in bright environments or prefer touch input
  • Wi-Fi is limited to Wi-Fi 5 and Wi-Fi 4 with no Ethernet port, which can be a drawback in environments where a wired network connection is needed
  • There is no backlit keyboard, making the device less practical in low-light conditions
  • Flash storage is not an NVMe drive, which results in lower sequential read and write performance compared to NVMe-based alternatives
  • The absence of a fingerprint scanner and 3D facial recognition means there are no hardware-based biometric login options
Who is this for?

This Chromebook is a reasonable fit for users who spend most of their time on web-based tasks, document editing, and light productivity work, where the large 16″ IPS display with a 1920x1200 resolution provides ample screen space for multitasking across browser tabs and cloud applications. The support for up to four external displays and a CPU capable of reaching 4.6GHz turbo across 12 threads also makes it a workable option for multi-monitor office setups where ChromeOS's app ecosystem is sufficient. Users who prioritize a capable integrated GPU for casual graphics tasks and need a system with DDR5 memory expandable up to 64GB will find the hardware headroom useful for more demanding browser-based or progressive web applications.

Who is this NOT for?

Users who need a genuinely portable, travel-friendly machine will find the 1,700g weight and 18mm chassis less than ideal for daily commuting or frequent on-the-go use. The 60Hz display with no anti-reflection coating and no touch support makes it a poor match for creative professionals, illustrators, or anyone working extensively in bright environments. The non-NVMe flash storage and lack of ray tracing, DLSS, or discrete GPU support means the device is firmly unsuitable for gaming, video production, or any workload requiring sustained high-throughput storage and graphics performance. Additionally, the absence of an Ethernet port and the ceiling at Wi-Fi 5 make it a weak choice for users operating in network-critical or enterprise wired environments.

Final Verdict

The Acer Chromebook Plus 516 CB516 is a well-specified machine within its category, offering a generous 16″ IPS display, a multi-threaded processor with a 4.6GHz turbo ceiling, and DDR5 memory support up to 64GB — a combination that gives it more staying power than typical entry-level Chromebooks. Its multi-display support and practical port selection add genuine utility for desk-based productivity use. That said, the device carries trade-offs in portability, display quality, and storage throughput that narrow its appeal to users whose workflows align closely with what ChromeOS and web-based applications can deliver. For those users, it represents a solid and capable platform; for anyone with heavier creative, gaming, or network-intensive demands, the hardware ceiling will become apparent quickly.
