DELL Inspiron 3520 laptop i5-1135G7 8GB 256GB SSD 1TB HDD 15.6 120Hz Win 10 Pro

15.6" 120 Hz laptop for everyday work

The Dell Inspiron 3520 pairs an 11th Gen Intel Core i5-1135G7 processor with 8GB DDR4 memory and a dual-drive layout of 256GB NVMe SSD plus 1TB HDD. Windows 10 Pro 64-bit is pre-installed on the solid-state portion for fast boot and application loading. The 15.6-inch IPS panel runs at 1920 x 1080 resolution with a 120 Hz refresh rate for smoother scrolling and video playback. Integrated Intel Iris Xe graphics handle the display output and light creative tasks.

Sustained load on a 2.40 GHz quad-core with Iris Xe

Under continuous demand the i5-1135G7 can reach 4.2 GHz turbo across its four cores and eight threads while sharing the 8MB L3 cache. The 41 WHr three-cell battery and 65 W power supply set the energy envelope for prolonged sessions. Thermal behaviour will reflect the compact 0.74-inch chassis and the integrated graphics sharing system memory bandwidth with the CPU. Heavy multi-threaded workloads or extended gaming will push the cooling limits faster than a discrete-GPU design.

Practical limits of the 802.11ac

Wireless performance tops out at the 802.11ac standard, so congested 5 GHz environments may see reduced throughput compared to newer Wi-Fi generations. Bluetooth 5.0 provides stable peripheral connections within typical indoor range. The single USB 2.0 port and HDMI output constrain high-speed external storage or multi-monitor setups. The 2230 M.2 slot limits future SSD upgrades to that shorter form factor.
