DELL Latitude 7490 laptop 14" Touch i7-8650U 8GB 256GB

Business laptop for mobile professionals

The Dell Latitude 7490 is a 14.0 inch touchscreen notebook built for people who work away from a desk. It runs Windows 10 Pro on an Intel Core i7-8650U processor with four cores and eight threads. Integrated Intel UHD Graphics 620 handles everyday visual tasks. The system includes 8GB DDR4 memory and a 256GB M.2 NVMe PCIe SSD.

Quad-core i7-8650U with 4.2 GHz turbo

The processor operates at a 1.9 GHz base frequency and can reach 4.2 GHz under load. Eight megabytes of smart cache feed four cores and eight threads. This specification determines whether the laptop suits workloads that rely on burst multi-thread performance rather than sustained high clock speeds.

Sustained output limited by thermal envelope

Under continuous load the ultra-low-power chip throttles to stay within its thermal envelope, so clock speeds settle below the peak turbo figure. The integrated GPU shares system memory and cooling capacity with the CPU. Battery life benefits from the efficient design during typical office use, but heavy compute tasks will reduce run time.
