Purpose-built desktop

This HP All-in-One 27" Touchscreen integrates the Intel Core Ultra 7 155U processor with 12 cores and 14 threads, 32 GB DDR5 memory and a 1 TB NVMe SSD behind a 1920 x 1080 IPS panel. Windows 11 Pro is pre-installed and a wireless keyboard and mouse are included in the box.

Who it suits and who it does not

The touchscreen, integrated graphics and fixed 27" form factor suit office workers, students and home users who want a tidy single-unit PC for productivity and video calls. Buyers who need discrete graphics for gaming or rendering, or who require user-replaceable components, should look at a traditional tower system.

Deciding specification

The Intel Core Ultra 7 155U with 12 cores, 14 threads and a 4.8 GHz maximum turbo frequency is the single figure that determines whether this all-in-one delivers the multi-threaded performance your workload demands.

Questions about this item

How is the 27" touchscreen all-in-one installed, and what step is often missed?

Place the unit on a stable surface, connect the power cable, then pair the wireless keyboard and mouse via their USB receiver; the step often missed is inserting batteries into both peripherals before pairing.

What maintenance or replacement will the 32 GB DDR5 memory and 1 TB NVMe SSD need later?

The DDR5 memory and NVMe SSD are soldered or not user-accessible, so no routine upgrades are possible; keep vents clear of dust to maintain cooling for the Core Ultra 7 155U processor.

What limit appears first on the Intel integrated graphics during sustained workloads?

The 250-nit FHD+ panel and shared system memory cap graphics performance, so thermal throttling on the 12-core 14-thread CPU typically arrives before frame-rate drops in heavy tasks.
