Lenovo Yoga All-in-One PC 27" QHD 120Hz Ultra 7 255H 16GB 8TB Arc 140T Luna Grey

All-in-One for creative work

The Lenovo Yoga All-in-One combines a 27-inch IPS QHD display running at 120 Hz with an Intel Core Ultra 7 255H processor and 16 GB of LPDDR5X memory. Integrated Intel Arc 140T graphics share system memory, while an 8 TB PCIe NVMe SSD provides large local storage for media projects. Windows 11 Home, WiFi 7 and Bluetooth 5.4 complete the package for home-office creators who want a single tidy unit.

Sustained workload behaviour

The 170 W power supply feeds a 16-core, 16-thread CPU that can reach 5.1 GHz boost clocks, but the all-in-one chassis limits how long peak frequencies hold under continuous multi-threaded rendering or compile jobs. Shared graphics memory means heavy GPU compute competes with the 16 GB RAM pool, so extended 3D or video sessions may throttle sooner than a discrete-card desktop. Thermal headroom is fixed by the sealed design.

Installation and common issues

Setup is minimal: place the unit, connect the included wireless keyboard and mouse, and run Windows 11 first-boot. The bundled Dockztorm USB hub adds extra ports at up to 5 Gbps for peripherals. Because memory is soldered LPDDR5X and storage is internal NVMe, later upgrades are not possible; buyers needing more RAM or a second drive should choose a tower system instead.
