The single specification that decides fit is the 10-core i7-1255U paired with a 512 GB solid-state drive. Integrated graphics handle the 15.6 inch 1920 x 1080 display without a discrete GPU. Buyers who want more storage or a dedicated graphics card for gaming or rendering should look elsewhere.

Questions about this item

How does the 4.7 GHz turbo on the 10-core i7-1255U behave when the laptop is running a sustained heavy workload?

The processor can reach 4.7 GHz on one or two cores for short bursts; under continuous load the long-term speed settles lower and is governed by the cooling system's ability to dissipate heat.

What does the 802.11ac wireless radio mean for real-world throughput on this laptop?

The 802.11ac link typically delivers several hundred megabits per second in practice, so large file transfers or video streams run smoothly on a compatible router.

What physical drive bay or slot does the 512 GB SSD occupy in this chassis?

The solid-state drive fits into an internal M.2 slot; the 2.5-inch hard-drive bay is not used because no mechanical drive is installed.
