The Dell G15 5515 has a light grey colour with blue dots, which looks like recycled plastic – which it is not. The back is marked with an orange G on the right-hand edge, which indicates that this model is a gamer. The underside is largely open-ended to bring fresh air to the components.

When opened, the Dell G15 reveals a classic backlit keyboard with a key layout reminiscent of an office model. The touch is also far from satisfactory and sounds hollow.
Thus, the arrow keys are surrounded by the Page UP and Down keys; we also notice the presence of a numeric keypad with the shortcut keys to the calculator or the CE and +/- keys.
A choice that is all the more strange given that the shortcut that allows you to change the “SmartShift” performance mode at Dell is not even written on the keyboard: it is the shortcut Fn+F9 – whereas it is indicated on the manufacturer’s website that it is Fn+G. We had to download the manual to find the information.

The touchpad is slightly off-center to the left. It does not have separate buttons for left or right click, but simple buttons under the touch surface.

The connectivity is spread out on the sides and back of the PC, between the vents. On the left side, we have an RJ45 port, the headphone/mic jack as well as a charging light. On the right, there are two 3.2 Gen1 ports, one of which is capable of charging a device even when the PC is turned off. Finally, the back side houses a USB 3.2 Type-C port, a USB3.2 Gen1 port, an HDMI port and the charging jack.

Wireless connectivity is provided by the Intel AX1650 Killer chip, which is none other than an AX200 with a software overlay that offers more settings. Thus the AX1650 Killer allows like the AX200 to have Wi-Fi 6 (2400 Mb/s) and Bluetooth 5.2. The webcam captures in a definition of 720p and does not offer much detail. It is particularly is noisy in low light.

Cooling is provided by two fans in the corners under the hinge. Four radiators, and thus four openings are responsible for removing heat from the processor and graphics card. Surprisingly, Dell did not place the processor and graphics card on the accessible side of the motherboard; they are located under the keyboard and the heatpipes are not visible.

This probably explains the 51°C reading above the keyboard, it is in fact vents at this level. However, the temperatures in strategic places (ZQSD keys, arrows and touchpad) do not suffer from the heat and do not rise above 34°C.

Noise levels are also contained, with 42 dB measured in “normal” mode and 46.6 dB with SmartShift activated via the Fn+F9 shortcut.

The software suite that controls the performance modes and various settings of the Dell G15 is very limited. Dell has actually reused the Alienware Control Center software by amputating many features. You’ll have to connect to the Microsoft Store to download certain modules, because as it is, the audio settings (Nahimic) or SmartShift are not accessible; incomprehensible! Launching the application after starting the PC is also quite long (over a minute). So we’ll settle for the most useful shortcut (Fn+F9) which activates SmartShift and a fan that allows you to make the most of the Ryzen 7 and the 125W GeForce RTX 3060.

Opening the Dell G15 is particularly easy. To access the components, simply remove 8 Phillips screws and slide the shell off.

Apart from the processor and GPU soldered to the motherboard, all the components are easily removable. Two M.2 ports in the 2230/2280 format are accessible; the M.2 SSD provided is in the unusual 2230 format.
Dell provides on its website a complete step-by-step disassembly guide for all the elements that make up this G15, such as the USB ports, the touchpad, etc.

The Dell G15 is equipped with an IPS panel displaying 1920 x 1080 px at 120 Hz. Its integration is more than classic, with large edges bringing its occupancy rate to 69%.

Contrast was measured at 1544:1, a high value for an IPS panel. The average temperature was measured at 6638 K, which is very close to the video standard (6500 K).
On the other hand, the Dell panel does not shine with its brightness (272 cd/m²). It is best to stay indoors. Fortunately, the matte coating offers a low reflectance (20.8% of reflected light) which means you don’t have to play with the screen’s angle to avoid reflections.

The colorimetry, on the other hand, leaves something to be desired. We measured a delta E of 5.5, far from the threshold of 3 under which the eye cannot distinguish the difference between the original color and the restored color.

An important detail for a PC dedicated to gaming, the remanence of the panel was measured at 15 ms, a value low enough to play in good conditions, but almost twice as important as the best in our database (8 ms).
