HP 27 all-in-one PC 27" touchscreen Intel Core Ultra 7-255U 64GB DDR5 4TB NVMe

27-inch touchscreen all-in-one

This HP 27 all-in-one PC combines a 27-inch IPS FHD touchscreen with an Intel Core Ultra 7-255U processor, 64GB DDR5 memory and a 4TB PCIe NVMe SSD. It ships with Windows 11 Home, WiFi 6, Bluetooth 5.4, a webcam, wireless keyboard and mouse, and a 90W power supply. The integrated Intel Graphics drive the 1920x1080 60Hz display for everyday productivity and media.

Sustained-load behaviour

The 12-core, 14-thread Ultra 7-255U runs at a 2.00GHz base with a 5.2GHz maximum turbo, while the 90W supply limits total system draw. Under continuous multi-threaded workloads the processor will settle below peak turbo to stay within the thermal and power envelope, so long renders or compiles run at a steady but reduced frequency rather than the burst speed. Shared system memory feeds the integrated graphics, so heavy GPU tasks also contend for the 64GB DDR5 pool.

Upgrade perspective

This configuration replaces a conventional desktop-and-monitor pair for users who want a single-cable setup with abundant memory and storage. The jump is worthwhile when 64GB DDR5 and 4TB NVMe eliminate the need for immediate upgrades, and when touch input adds value for kiosk, creative or collaborative workflows. Buyers who need discrete graphics performance, internal expansion slots or a higher-refresh panel will not find those here.
