Questions about this item

How does the 10-core i7-1255U perform in a real machine?

The 10-core processor (2P+8E) has a base clock of 3.5 GHz and can boost up to 4.7 GHz with 12 MB SmartCache and 12 threads, giving strong multi-tasking responsiveness for everyday workloads.

What does the HDMI 1.4 port actually support?

The single HDMI 1.4 port carries video and audio to an external display; its bandwidth limits output to the panel's native 1920 x 1080 resolution.

What are the exact dimensions and weight for fitting it in a bag?

The chassis measures 14.11 x 9.27 x 0.82 inches and weighs 3.65 lbs, so it fits most 15.6-inch laptop sleeves and backpacks.
