Lenovo IdeaPad 3 15 laptop i7-1255U 24GB 2TB 15.6" FHD touchscreen

15.6" FHD touchscreen laptop for everyday work

The 15.6 inch full HD IPS touchscreen delivers 1920 by 1080 resolution at 60 Hz with an anti-glare finish and 300 nits brightness. A 12th generation Intel Core i7-1255U processor provides ten cores split between two performance and eight efficient cores, reaching up to 4.7 GHz turbo frequency. Integrated Intel Iris Xe graphics handles display output and light creative tasks. The system includes 24 GB of DDR4 memory and a 2 TB PCIe SSD running Windows 11 Home.

Sustained load behaviour with ten-core hybrid CPU

Under continuous workloads the two performance cores maintain higher clocks while the eight efficient cores handle background threads, keeping the 12 MB smart cache fed without thermal throttling typical of short bursts. The 60 Hz panel and integrated graphics mean frame pacing stays consistent during long video playback or document editing sessions. DDR4 memory bandwidth and the PCIe SSD keep data flowing for multi-tab browsing and office suites without the slowdown seen in shorter benchmark runs.

Thermals, noise and power in normal use

The slim chassis measuring 14.4 by 9.31 by 0.78 inches and weighing 3.74 pounds uses a fan-assisted cooler that remains quiet during typical productivity tasks such as web browsing, video calls and spreadsheet work. Surface temperatures stay comfortable on the palm rest and keyboard deck thanks to the efficient-core architecture reducing sustained package power. The 720p webcam with privacy shutter, Wi-Fi 6 and Bluetooth 5.1 add functionality without increasing acoustic output.
