HP ENVY x360 15z Ryzen 7 3700U 16GB 256GB 15.6 Touch laptop

Convertible 15.6-inch touch laptop

The HP ENVY x360 15z is a convertible laptop built around an AMD Ryzen 7 3700U processor with four cores and a 2.3 GHz turbo frequency. It ships with 16GB of DDR4 memory and a 256GB PCIe NVMe SSD for fast boot and application load times. The 15.6-inch Full HD touchscreen supports pen and finger input for creative work or note-taking. Windows 10 Home 64-bit is pre-installed.

Sustained workload behaviour

The Ryzen 7 3700U maintains its 2.3 GHz turbo across all four cores during extended sessions such as video encoding or large spreadsheet recalculation. Integrated Radeon Vega 10 graphics share system memory, so the 16GB DDR4 pool remains the limiting factor for GPU-intensive tasks. Thermal management keeps clocks stable without aggressive throttling during typical office and multitasking loads. Battery capacity of 56WHr supports several hours of mixed use away from the 65W adapter.

Thermals noise and power

The 65W power supply delivers enough headroom for the processor and integrated graphics under normal productivity workloads. Fan noise stays low during web browsing, document editing and video playback, rising only when the CPU and GPU are both saturated. Surface temperatures remain comfortable on the keyboard deck and palm rests during typical use. The 4-cell battery and efficient SoC design help keep power draw modest for a 15.6-inch convertible.
