15.6" FHD touchscreen laptop

The Lenovo IdeaPad 3 15 is a 15.6-inch laptop with a 1920 x 1080 IPS touchscreen. It runs Windows 11 Pro and includes a Microsoft Office licence. The system is built around a 12th Generation Intel Core i7-1255U processor with 24GB of DDR4 memory and a 2TB PCIe SSD.

Intel Core i7-1255U sustained performance

The 10-core processor combines two performance cores and eight efficient cores with a 4.7 GHz turbo frequency. Under sustained load the efficient cores handle background work while the performance cores maintain higher clocks for longer periods. The 12 MB smart cache helps reduce latency during extended multitasking sessions.

Thermals noise and power in daily use

The 0.78-inch chassis weighs 3.74 pounds and uses a fan-assisted cooling solution. In typical office workloads the system runs quietly with the 300-nit anti-glare display at comfortable brightness. Integrated Iris Xe graphics share system memory, keeping power draw moderate during video playback or light creative tasks.
