[In-Depth Comparison] MSI Stealth GS66 (12Ux) vs Acer Predator Triton 500 SE (PT516-52s) – an unexpected winner

Intel is back on top in the laptop space, delivering its strongest showing in years. Tiger Lake did well last year and showed that Team Blue hasn’t given up. However, the Alder Lake CPUs are what put Intel back on top, delivering the final blow to AMD, and solidifying itself as the most powerful CPU manufacturer, for now at least.

Today we have two laptops powered by this new CPU family, that target the gaming and Creator audience, delivering features that are usable by both.

When it comes to both the MSI Stealth GS66 (12Ux) and the Acer Predator Triton 500 SE (PT516-52s), we have stealthy chassis paired with the most powerful available hardware right now. There are also very good displays on board, delivering on the Creator part.

Today we are presenting you with an in-depth comparison between the MSI Stealth GS66 (12Ux) and the Acer Predator Triton 500 SE (PT516-52s).

Design and construction

The MSI laptop can be mistaken for a black slab of metal, as that’s all that there is to its design. It’s entirely built out of aluminum and comes with sharp edges and rounded corners. The lid has a very minimal-looking MSI logo, which is glossier, but still comes in black. The rectangular structure also means a sturdy chassis, with the lid being exceptionally durable, while also opening with one hand.

The Triton 500 SE has a more stylized design, with some gaming features. The laptop is also made from aluminum and has many of the same characteristics, including sharp edges and rounded corners. The vents of the back have an aggressive design fitting the Predator brand. In terms of branding here it is also kept to a minimum, with only a small Predator badge on the lid. Its lid also opens with one hand.

Keyboard and touchpad

Both devices have decided to skip out on the NumPad, looking to deliver a better overall user experience. This results in two keyboards with large keycaps, including the arrow keys.

On the MSI model, the unit has shallow key travel and quiet feedback, which is less than ideal for gaming and productivity. But being that the laptop is called the Stealth, we should have expected it. The gaming roots of the keyboard are expressed by the per-key RGB backlight. As for the touchpad, it has a wider aspect ratio than the display. The pad is covered in glass and has a fingerprint reader in the upper left corner. The experience that it offers is good enough, albeit the clicking mechanism is also a bit shallow.

Sadly, the Predator Triton isn’t that far ahead, delivering the same short key travel and not clicky feedback. The touchpad has a more standard aspect ratio with a fingerprint reader positioned in the same place. It is too covered in glass, offering smooth gliding.

Ports

The MSI Stealth’s I/O includes two USB Type-A 3.2 (Gen. 2) ports, and three USB Type-C 3.2 (Gen. 2) ports, one of which has Thunderbolt 4 support, an HDMI 2.1 port, an Ethernet port, and a 3.5 mm audio jack. This leaves enough connectivity for up to three additional monitors, which is crazy.

On the Predator, you have two USB Type-A 3.2 (Gen. 2) ports, two Thunderbolt 4 ports, an Ethernet port, a 3.5 mm audio jack, an HDMI 2.1 port, and an SD card reader.

Color coverage

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 the color coverage of both the MSI Stealth GS66 (12Ux) and the Acer Predator Triton 500 SE (PT516-52s).

Both laptops fully cover the sRGB gamut, while also showing substantial coverage of the DCI-P3 gamut with 96% for the MSI Stealth GS66 (12Ux) and 99% for the Acer Predator Triton 500 SE (PT516-52s).

Color accuracy

We tested the MSI Stealth GS66 using both the stock settings and our Design and Gaming profile applied. The first test is in the sRGB gamut, while the second test adjusts the white point to D65 and in the DCI-P3 gamut. Regardless of the white point adjustment and which gamut we tested in, the result stayed similar, with the dE value hovering around the 1.8 to 1.9 mark.

We also compare the scores of MSI Stealth GS66 (12Ux) with the default settings (left), and with the “Gaming and Web design” profile (right) against the P3-D65 color space.

Response time (Gaming capabilities)

We test the reaction time of the pixels with the usual “black-to-white” and “white-to-black” methods from 10% to 90% and vice versa.

Both laptops are very fast, but the MSI Stealth GS66 (12Ux) comes in with a quicker Fall + Rise time of 7.4 ms.

Health Impact / PWM (Blue light)

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 backlight is not lowered, but instead turned off and on by the electronics with a frequency indistinguishable by 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.

Both laptops use no PWM across all brightness levels, meaning that the displays are comfortable to use, without presenting any excessive eye strain in this aspect.

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.

Sound

The MSI device comes with front-firing speakers, with a large grill above the keyboard. As for the Predator, it comes with bottom-firing speakers, with two small grills on the bottom panel. Both setups deliver quality audio, but the speakers on the Predator do deviate from quality in the low, mid, and high frequencies.

Battery life

Both laptops come with similarly sized battery packs, with 99.9Wh for the MSI Stealth and 100Wh for the Acer Predator. Both of them also arrive with the same processor, the Core i7-12700H. This is why it’s so shocking to see that the Triton 500 SE performs a lot, a lot better, having leads of 4 hours and 43 minutes in Web browsing and 2 hours and 29 minutes in video playback. This was done using the Windows Better performance setting, screen brightness adjusted to 120 nits, and all other programs turned off except for the one we are testing the notebook with.

Performance

In terms of hardware, both laptops offer the Alder Lake H-series of processors and the RTX 30-series Ampere graphics.

CPU benchmarks

Here we tested the Intel Core i7-12700H inside both laptops. The MSI Stealth brings better performance in both the 3D and 2D Rendering tests, scoring 12% higher in Cinebench 20 and finishing the Photoshop benchmark just a tad quicker, by a margin of 0.1 seconds.

Results are from the Cinebench R23 CPU test (the higher the score, the better)


GPU benchmarks

Here we tested the NVIDIA GeForce RTX 3070 Ti inside both laptops, with the Triton laptop getting a slightly more powerful 115W version, while the Stealth dons the 105W version of the GPU. The small TGP increase seems to be doing the trick, as the 3070 Ti inside the Triton scores 6% higher in 3DMark Fire Strike and 5% higher in Unigine Superposition.

Temperatures and comfort

In terms of cooling, both devices deliver pretty well. The MSI Stealth comes with a total of seven heat pipes, three fans, and four heat sinks. Six of the pipes are entirely dedicated to the CPU and GPU. The seventh one targets the VRMs and the GPU memory.

On the side of Acer, we have a total of four heat pipes, with three that cool down both the CPU and GPU. The fourth one covers the GPU memory. The three fans siphon the heat away from the mainboard.

Verdict

These two machines come with more similarities than differences, but there are still some defining features that will help you to choose the right device for you. Both the MSI and Acer laptops arrive with a metal unibody that is durable and sleek.

The designs are grown-up and minimal, minimizing the gaming characteristics as much as possible. Maybe they went too far in the other direction, as the keyboard on both the Stealth and the Triton were unimpressive, delivering shorter than ideal key travel and decent, but not great feedback. They compensate, however, with wide I/O that can support multiple external monitors, if there is a need.

We were shocked to see the soldered RAM on the Triton 500 SE, as we believed that a large 16-inch notebook cannot be this bad, offering no RAM slots, but only two M.2 slots. The Stealth, on the other hand, supplies both RAM and SSD slots and takes the win for upgradeability. The displays here are of great quality providing great color coverage and accuracy, while also being very quick, resulting in an excellent gaming and Creator experience.

The MSI laptop also delivers front-facing speakers with no deviations from quality across all frequencies. What the Acer does better, is to bring more efficiency to the field, providing excellent leads in the battery life tests. In terms of performance, the MSI Stealth is better at CPU-intensive tasks, while the Triton 500 SE is slightly more powerful in GPU-related benchmarks.

Lastly, when it comes to cooling, MSI has finally fixed the horror that was their cooling in 2021 and before. The Stealth deals with the problem by throwing six heat pipes at it, along with three fans, resulting in low temperatures and high speeds. The Acer also does really well in that regard, but not as good as its competitor.

If it were up to us, we would go with the MSI device, simply because we are suckers for performance and cannot imagine using a gaming laptop with no RAM upgradeability. Yes, you are losing in terms of battery life, but most of the time you will be plugged into a socket when gaming anyway. Then you have to add the speakers and the cooling, which overall round out the result for us.
