The thin 16-inch workstation combines NVIDIA’s RTX Spark N1X platform, up to 128GB of memory and a 99.9Wh battery, but its specialist performance comes at a steep price.
ASUS has built a laptop that sits close to the edge of what a portable Windows machine can do. The ProArt P16 with NVIDIA’s RTX Spark platform is a thin, 16-inch workstation aimed at developers, engineers, AI enthusiasts, 3D artists and video editors rather than casual buyers. It is fast, well made and unusually light for the class, but it is also expensive enough that most people will be better served by something cheaper and less specialised.
That caveat matters because the ProArt P16 is not a conventional creator laptop with a few premium touches added on top. ASUS has paired the RTX Spark N1X platform with a 20-core Grace CPU, a 6,144-core Blackwell RTX GPU, native CUDA support and up to 128GB of unified LPDDR5X memory. In practical terms, that opens the door to local AI work, large models, complex creative projects and other memory-hungry tasks that would overwhelm many mainstream systems. According to Windows Central, ASUS says the highest-memory configuration can handle large language models with up to 120 billion parameters.
The chassis is one of the machine’s strongest arguments. Windows Central says the laptop weighs 3.9 pounds and measures between 0.51 and 0.63 inches thick, yet still houses a 99.9Wh battery. That makes it markedly lighter than several competing RTX Spark systems while remaining surprisingly cool and quiet under load. The review reported surface temperatures of roughly 105°F across the keyboard deck and around 120°F near the rear exhaust, with fan noise staying below 50dB even during demanding workloads. PC Gamer and Notebookcheck reached a similar conclusion, describing the design as unusually slim and light for a workstation this powerful, even if both noted the high asking price.
ASUS has also done a strong job with the user-facing hardware. Windows Central praised the OLED touchscreens, which come in 3K and 4K variants with 100% DCI-P3 coverage, HDR support and a variable refresh rate from 30Hz to 120Hz. The review found the 3K panel the better all-round choice for most buyers, even though the 4K option is available on higher-end configurations. The same review singled out the keyboard, large haptic touchpad, four-speaker Dolby Atmos audio and the bundled software. MyASUS includes display controls, OLED care functions, colour-gamut options and memory allocation settings, giving the machine a deeper level of adjustment than many rivals.
Performance is strong, though not always decisive against other RTX Spark laptops. Windows Central found that the ProArt P16 generally stayed close to competitors from Microsoft and HP in CPU and CUDA tests, with graphics results varying depending on the benchmark. The review also noted that SSD performance lagged behind some rivals, even if the laptop remained responsive in day-to-day use. Tom’s Guide and PC Gamer likewise reported strong gaming, rendering and AI performance, while also flagging compatibility concerns tied to the ARM-based platform and the premium price. ASUS’s own specification page confirms up to 128GB of memory, up to 2TB of storage, Wi-Fi 7, Bluetooth 5.4 and a wide port selection, including USB4, HDMI 2.1 and an SD Express card reader.
Battery life is respectable rather than class-leading. Windows Central recorded just under 10 hours in mixed real-world use, which is solid for a high-performance workstation with a large OLED panel, but still trails the best Snapdragon X and Apple Silicon laptops. Tom’s Guide reported more than 12 hours in its own testing, underlining how workload and measurement method can materially change the result. The broader picture is clear: the ProArt P16 is one of the most capable Windows laptops available for people who can genuinely use RTX Spark, but it is far from a universal recommendation. For the right buyer, it is an impressive glimpse of where portable Windows workstations are heading. For everyone else, it is a very expensive way to do ordinary laptop work.
