Intel Core Ultra 9 386H – 16 Cores, 50 TOPS NPU for Copilot+ AI
Under the hood is the Intel Core Ultra 9 Processor 386H — 16 cores, 16 threads, base clock at 2.1 GHz boosting up to 4.9 GHz, with an 18MB cache. The integrated Intel NPU delivers up to 50 TOPS, meeting the Copilot+ PC threshold for on-device AI features like instant file retrieval, quick summaries and faster searches.
There’s no discrete GPU here — graphics are handled by the Intel integrated graphics built into the processor.
32GB LPDDR5X RAM, 1TB PCIe 4.0 NVMe SSD
On the memory side, 32GB LPDDR5X is soldered on board and not upgradeable. Storage is a 1TB M.2 NVMe PCIe 4.0 SSD sitting in the single M.2 2280 PCIe 4.0×4 slot.
Dual 14-inch OLED 3K 144Hz Touchscreens – 1000 Nits HDR, 100% DCI-P3, PANTONE Validated
Both screens are identical 14-inch ASUS Lumina OLED panels running at 3K (2880 × 1800) resolution in a 16:10 aspect ratio. Refresh rate hits 144Hz with a 0.2ms response time.
Peak HDR brightness reaches 1000 nits, colour coverage spans 100% DCI-P3, and the panels carry VESA DisplayHDR True Black 1000 and PANTONE Validated certifications. Screen-to-body ratio is 93%. Both screens are glossy touchscreens with stylus support, and an anti-reflection coating plus E Reading mode help cut down eye strain during long sessions.
Dual-Screen Modes – Magnetic Keyboard, Integrated Kickstand
The magnetic keyboard detaches and reattaches quickly, letting users switch between modes in seconds. There’s a dual-screen productivity mode, a standard laptop mode, and a sharing mode where the second screen faces outward. An integrated kickstand holds the displays at the right angle in each configuration. The whole thing folds into one device — no separate parts to lose.
The keyboard has 1.7mm key travel with a precision touchpad.
6 Speakers with Dolby Atmos, FHD IR Camera
Audio runs through six speakers with Dolby Atmos support and Smart Amp Technology. A built-in array microphone with AI Noise Canceling handles calls and voice input.
Up top is an FHD camera with IR for Windows Hello face authentication — no password needed.
Thunderbolt 4, USB 3.2, HDMI 2.1, Wi-Fi 7 Connectivity
For a dual-screen machine this thin, the port spread is reasonable:
- 2× Thunderbolt 4
- 1× USB 3.2 Gen 2 Type-A
- 1× HDMI 2.1 FRL
On the wireless side, there’s Wi-Fi 7 (802.11be) tri-band 2×2 and Bluetooth 5.4.
99Wh Battery – Fast Charge to 60% in 49 Minutes
At 99Wh (4-cell Li-ion, 4S1P), this is about as large as a laptop battery gets before hitting airline carry-on limits. Fast charging brings it from flat to 60% in 49 minutes. The included 100W USB-C adapter (100–240V, 50/60Hz) handles charging.
Ceraluminum Build – MIL-STD-810H Military Grade Durability
The chassis, hinge and kickstand are all built from Ceraluminum — ASUS’s ceramic-aluminum material. The laptop meets the US MIL-STD-810H military-grade standard for durability and carries Energy Star and RoHS compliance certifications.
