The Asus ProArt P14 has launched as the company’s first 14-inch laptop built around Nvidia’s RTX Spark chip, pairing a 1,600-nit OLED display with up to 128 GB of unified memory inside a 1.48 kg chassis. It’s the smallest of three RTX Spark machines Asus has now detailed, and the first to actually ship.
The laptop is listed on Asus’s site as the H7407BA. It carries a 90 Wh battery, a 120 Hz, 2880 x 1800 OLED display with variable refresh rate and Nvidia G-Sync support, and 100% coverage of the DCI-P3 colour gamut across every configuration Asus offers.
What’s inside the Asus ProArt P14
Buyers choose between two touch-enabled panels. The brighter option reaches 700 nits in SDR mode and 1,600 nits in HDR; the second tops out at 500 nits SDR and 1,100 nits HDR, a distinction TechPowerUp pulled from Asus’s own product listing before wider coverage caught up. Both panels support a pressure-sensitive stylus, which fits the creative work the ProArt line is built for, and both run on the same RTX Spark silicon regardless of which display a buyer picks.
That silicon is a 20-core Nvidia Grace Arm CPU fused with a Blackwell-derived RTX GPU carrying 6,144 CUDA cores. It makes the ProArt P14 an Arm-based Windows laptop, not the x86 machines Asus has sold under the ProArt name until now. Asus quotes AI performance of up to one petaflop using the chip’s lowest-precision format; that figure comes from Asus, not an independent benchmark, and should be read as such.
RAM tops out at 128 GB. Because RTX Spark uses a unified memory architecture, that pool is shared between CPU and GPU workloads rather than split into separate system RAM and VRAM allocations.
Unified memory, and why teqpost has been tracking it
We flagged this shift on 24 August 2026, when a Windows 11 build surfaced hidden unified memory controls, pointing to Microsoft preparing OS-level support for shared CPU/GPU memory pools ahead of hardware that would need it. The ProArt P14 is one of the first shipping laptops where that actually matters: its 128 GB isn’t a conventional split of dedicated VRAM and system RAM, it’s a single pool the operating system has to manage dynamically. Whether Windows 11 exposes those controls to ProArt P14 owners at launch, or only later through an update, is still unclear.
Asus isn’t alone in building around Nvidia’s Grace-plus-Blackwell combination. MSI has already started shipping its XpertStation WS300 workstation around the related GB300 superchip, and Asus is extending RTX Spark across its own ProArt range well beyond the P14.
What to watch next
Asus has confirmed two further RTX Spark machines. The ProArt P16, pitched as a rival to the 16-inch MacBook Pro, adds a 4K Tandem OLED display, a 99 Wh battery and 240 W charging, and is due before the end of 2026. The ProArt GR1X, a mini PC rebranded from the ProArt Mini PC, will offer multiple RTX Spark configurations, up to 128 GB of unified memory and 180 W charging over one of its four USB-C ports.
Pricing and a firm release date for the ProArt P14 itself have not been confirmed.
