Dell G16 7630 review – its CPU boosts up to 200W
Display quality, Health impact (PWM), Sound
Dell G16 7630 is equipped with an IPS panel, model number Innolux 4N45R-160GME (CMN161D, N160GME-GQ1). It comes with a 165Hz refresh rate. Its diagonal is 16″ (40.6 cm), and the resolution – 2560 x 1600p. Additionally, the screen ratio is 16:10, the pixel density – 178 ppi, and their pitch – 0.13 x 0.13 mm. The screen can be considered Retina when viewed from at least 46 cm (from this distance, the average human eye can’t see the individual pixels).
Viewing angles are good. We offer images at different angles to evaluate the quality.
Also, a video with locked focus and exposure.
The maximum measured brightness is 361 nits (cd/m2) in the middle of the screen and 355 nits (cd/m2) average across the surface with a maximum deviation of 9%. The Correlated Color Temperature on a white screen and at maximum brightness is 6100К.
In the illustration below you can see how the display performs from a uniformity perspective. The illustration below shows how matters are for operational brightness levels (approximately 140 nits).
Values of dE2000 over 4.0 should not occur, and this parameter is one of the first you should check if you intend to use the laptop for color-sensitive work (a maximum tolerance of 2.0). We measured a good contrast ratio – 1200:1.
To make sure we are on the same page, we would like to give you a little introduction to the sRGB color gamut and the Adobe RGB. To start, there’s the CIE 1976 Uniform Chromaticity Diagram that represents the visible specter of colors by the human eye, giving you a better perception of the color gamut coverage and the color accuracy.
Inside the black triangle, you will see the standard color gamut (sRGB) that is being used by millions of people on HDTV and on the web. As for the Adobe RGB, this is used in professional cameras, monitors, etc for printing. Basically, colors inside the black triangle are used by everyone and this is the essential part of the color quality and color accuracy of a mainstream notebook.
Still, we’ve included other color spaces like the famous DCI-P3 standard used by movie studios, as well as the digital UHD Rec.2020 standard. Rec.2020, however, is still a thing of the future and it’s difficult for today’s displays to cover that well. We’ve also included the so-called Michael Pointer gamut, or Pointer’s gamut, which represents the colors that naturally occur around us every day.
The yellow dotted line shows Dell G16 7630’s color gamut coverage.
Its display covers 97% of the sRGB/ITU-R BT.709 (web/HDTV standard) in CIE1976, and 78% of DCI-P3, ensuring a super vibrant and attractive picture.
We tested the accuracy of the display with 24 commonly used colors like light and dark human skin, blue sky, green grass, orange, etc.
Below you can compare the scores of the Dell G16 7630 with the default settings sRGB.
The next figure shows how well the display is able to reproduce really dark parts of an image, which is essential when watching movies or playing games in low ambient light.
The left side of the image represents the display with stock settings, while the right one is with the “Gaming and Web Design” profile activated. On the horizontal axis, you will find the grayscale, and on the vertical axis – the luminance of the display. On the two graphs below you can easily check for yourself how your display handles the darkest nuances but keep in mind that this also depends on the settings of your current display, the calibration, the viewing angle, and the surrounding light conditions.
Response time (Gaming capabilities)
We test the reaction time of the pixels with the usual “black-to-white” and “white-to-black” method from 10% to 90% and vice versa.
We recorded Fall Time + Rise Time = 9 ms.
After that, we test the reaction time of the pixels with the usual “Gray-to-Gray” method from 50% White to 80% White and vice versa between 10% and 90% of the amplitude.
Health Impact: PWM (Screen flickering)
Pulse-width modulation (PWM) is an easy way to control monitor brightness. When you lower the brightness, the light intensity of the display is not lowered, but instead turned off and on by the electronics with a frequency indistinguishable to the human eye. In these light impulses, the light/no-light time ratio varies, while brightness remains unchanged, which is harmful to your eyes. You can read more about that in our dedicated article on PWM.
Dell G16 7630’s display doesn’t use PWM for brightness adjustment.
Health Impact: Blue light emissions
Installing our Health-Guard profile not only eliminates PWM but also reduces the harmful Blue Light emissions while keeping the colors of the screen perceptually accurate. If you’re not familiar with the Blue light, the TL;DR version is – emissions that negatively affect your eyes, skin, and your whole body. You can find more information about that in our dedicated article on Blue Light.
Health Impact: Gloss-level measurement
Glossy-coated displays are sometimes inconvenient in high ambient light conditions. We show the level of reflection on the screen for the respective laptop when the display is turned off and the measurement angle is 60° (in this case, the result is 63.4 GU).
Sound
Dell G16 7630’s speakers produce a sound of good quality. Its low, mid, and high tones all have some deviations from clarity.

This difference in the clocks/power ratio between the G16 and other models with the same CPU is related to the variation in chip quality.
This tested G16 i7 apparently did badly in the silicon lottery.
i agree, we need more sample
good
nice
GPU option is the RTX 4070
I love my Dell 2023 G16. I have the 13650HX and the 4050 GPU for $1199. I have a 13900k and 4090 for video editing videos on my desktop, but I needed a laptop for editing while on vacation and traveling this summer. I would have bought the 4070 variant, but it wasn’t available for another few weeks and I needed something now. After placing my order through Dell.com, I hopped onto Amazon and ordered a WD Black SN850X 2TB and 64GB of Crucial ram for a total of $300 in upgrades. The G16 isn’t thin or light, but it… Read more »
Hey Ryan,
Whats your battery life look like if you just find yourself web browsing/ basic tasks?
Thanks
theres zero heat pipes
For what test it’s CPU reach upto 190W? Mine doesn’t reach that wattage.
