Chinese brand debuts 16-core AMD laptop with 99.9Wh battery under 1.8kg

Sixunited, a Shanghai-based laptop manufacturer, has launched the XN77-160M-CS featuring AMD’s latest Ryzen AI MAX+ 395 APU, beating major brands like Dell and Lenovo to market with the high-end processor. The laptop combines the rare 16-core Strix Halo chip with a massive 99.9Wh battery in an under-1.8kg aluminum chassis, targeting users who need both power and extended battery life.

What you should know: The XN77-160M-CS is one of only a handful of laptops to feature AMD’s Ryzen AI MAX+ 395 APU, also known as Strix Halo.

• The 16-core processor includes integrated Navi 3.5 graphics and a 50 TOPS NPU (neural processing unit) for AI workloads.
• Only HP’s ZBook Ultra G1a and Asus ROG Flow Z13 have been announced with this chip so far.
• Sixunited offers two thermal configurations at 85W and 120W, both supported by dual-fan cooling systems.

Key specs: The laptop packs premium components despite its compact form factor.

• Memory consists of non-upgradable LPDDR5X running at up to 8,000 MT/s speeds.
• Storage supports up to two PCIe 4.0×4 SSDs in M.2 2280 format for fast, high-capacity configurations.
• The 16-inch display runs at 2560×1600 resolution with 165Hz refresh rate and 100% sRGB coverage, with an OLED version planned for the future.

The big picture: The 99.9Wh battery represents the maximum capacity allowed by most airlines while maintaining portability.

• Despite the large battery, the chassis weighs under 1.8kg and uses aluminum and mylar construction materials.
• The XN77-160M-CS follows a barebones design approach, meaning it may appear under different brand names as Sixunited often acts as an OEM supplier.

Competitive landscape: Pricing details remain undisclosed, but comparable laptops command premium prices.

• Asus’ AI MAX+ 395 laptop starts at $2,099, while HP’s device begins at $4,099.
• AMD’s Strix Halo platform has mostly appeared in mini-PCs like the GMKTec EVO-X2, Beelink AI Mini, and AOOSTAR NEX395 until now.

Why this matters: Sixunited’s launch highlights growing interest in AMD’s high-end mobile processors and provides another option for users seeking powerful laptops with extended battery life in a compact form factor.
