Gaming laptop with RTX 3060

This Dell G15 5520 is a new 15.6 inch gaming laptop built around an Intel Core i7-12700H processor with 14 cores and 20 threads. It pairs that CPU with an NVIDIA GeForce RTX 3060 graphics card and 16 GB of DDR5 memory running at 4800 MHz. The 512 GB NVMe solid-state drive holds the operating system and games. It suits buyers who want a portable machine for modern titles and multitasking.

Sustained load behaviour

The 120 Hz IPS panel delivers 300 nits brightness with anti-glare coating for extended sessions. A 240 W AC adapter powers the 14 core processor up to 4.7 GHz boost clocks while charging the 84 Whr six-cell battery rated for up to eight hours of mixed use. Thunderbolt 4 and HDMI 2.1 ports allow external displays without dock bandwidth limits. The chassis measures 14.1 by 10.7 by 0.80 inches and weighs 5.9 lbs.

Setup checks before ordering

Verify that your external monitors support HDMI 2.1 or DisplayPort 1.4 over Thunderbolt 4 for full resolution and refresh rate. Confirm the single 512 GB NVMe drive meets your storage needs or plan an internal upgrade. The laptop ships with Windows 11 Home and includes Wi-Fi 6 AX201 plus Bluetooth 5.2 for wireless peripherals. Ensure the 240 W power brick fits your travel bag or desk outlet arrangement.

Questions about this item

How loud or hot does the i7-12700H and RTX 3060 run under sustained load with the 240W adapter?

The 240W AC adapter supplies enough headroom for the 14-core i7-12700H and RTX 3060, while the 84Whr 6-cell battery supports up to 8 hours of mixed use.

Which peripherals or cables are required to use the Thunderbolt 4 port at 40Gbps with DisplayPort 1.4?

A certified Thunderbolt 4 or USB4 cable is needed for 40Gbps throughput and DisplayPort 1.4 video; standard USB-C cables will fall back to lower speeds.

Will the HDMI 2.1 and three USB 3.2 Gen 1 ports work with my older 1080p monitor and USB-A accessories?

Yes — HDMI 2.1 drives 1080p at high refresh rates, and the three USB 3.2 Gen 1 Type-A ports are fully backward compatible with existing USB-A devices.
