HP ProBook 640 G8 14" FHD i5-1145G7 16GB 256GB SSD Windows 11 Pro Silver

Business laptop with 14" FHD IPS display

The HP ProBook 640 G8 is a 14.0-inch business laptop running Windows 11 Pro. It uses an Intel Core i5-1145G7 quad-core processor with 8 threads and a 2.6 GHz base frequency. The system includes 16 GB of DDR4-3200 memory and a 256 GB PCIe NVMe SSD. Integrated Intel Iris Xe Graphics shares system memory.

Sustained workload behaviour on quad-core processor

The i5-1145G7 can reach 4.4 GHz with Intel Turbo Boost Technology during demanding tasks. Its 8 MB L3 cache helps maintain throughput when multiple applications run together. The 250-nit anti-glare IPS panel covers 45% NTSC colour space, staying readable during long sessions. Shared graphics memory scales with the 16 GB DDR4 pool.

Practical limits of integrated graphics

Intel Iris Xe Graphics relies on shared system memory rather than dedicated video RAM, limiting 3D performance for heavy rendering. The 256 GB NVMe drive holds the operating system and core applications but fills quickly with large media libraries. Wi-Fi 6 AX201 (2x2) and Bluetooth 5.2 provide modern wireless connectivity for office peripherals.
