Retaining that sleek achromatic metallic plan and slimline chassis seen successful older Stealth models, the 12U bid has undergone a important upgrade. but it comes astatine a cost. The 12UGS variant is an incredibly costly prime for gaming laptops, though for sheer show power, we seldom recovered ourselves wanting during this review. 

For starters, 12UGS  packs a stronger show than its predecessors, which see the MSI GS66 Stealth and MSI Stealth 15M. MSI’s moved distant from the erstwhile Intel i7 processors, equipping each 12U exemplary with an Intel Alder Lake i9 processor, 2TB of SSD storage, 32GB RAM and, for the 12UGS specifically, an Nvidia RTX 3070 Ti. Needless to say, it’s beauteous beefy wherever gaming laptops are concerned.

There’s nary denying you’ll find cheaper gaming laptops elsewhere, but the Stealth GS66 12UGS targets those seeking the highest show from PC games. It’s beauteous casual to transportation astir too, fitting these awesome specs into a compact bundle that ne'er felt restrictive. The RGB keyboard was comfy to use, there’s a bully wide trackpad, and ports are conveniently placed without going overboard. 

Just beryllium warned, it gets loud, and aft prolonged gaming sessions connected higher settings, it started getting hot. Take attraction erstwhile utilizing this but if you’ve got the money, you’ll get bully usage retired of the 12UGS, particularly if you're blessed to plug successful a headset if things get excessively noisy. Still, fixed the stronger artillery beingness this laptop brings, anyone seeking a caller portable gaming instrumentality should see the MSI Stealth GS66 12UGS.

The MSI Stealth GS66 12UGS is disposable successful the US, UK, and other regions worldwide, costing $2,499 (£3,099 / AU$3,459). However, portion MSI Stealth laptops are readily available, we couldn’t find this circumstantial mentation being sold successful Australia. 

Even by premium standards, that’s highly pricey, yet little costly than competitors similar the Razer Blade 15 (2022) oregon Gigabyte Aorus 17G (2021).

That’s not astonishing fixed however costly gaming laptops tin be, but you bash get plentifulness for your wealth present truthful we would hesitate to assertion it's overpriced. This peculiar exemplary comes equipped with an Intel Core i9-12900H 2.90GHz, an Nvidia RTX 3070 Ti GPU, 32GB of DDR5-4800 RAM, a UHD 4K show astatine 120Hz (with varying show options), and 2TB NVMe PCIe Gen4x4 SSD, aft all.

MSI Stealth GS66 12UGS: Design 

  • Ergonomic design
  • Easy to transportation astir  
  • Plenty of ports 

For a gaming laptop packing this overmuch power, the 12UGS’s elegant plan served america good for day-to-day activities. Thanks to the smaller chassis and polished achromatic metallic design, the 12UGS has a coagulated physique prime to it. 

It’s not excessively dense oregon big, making it casual to transportation astir successful a question bag, and felt bully to hold. Admittedly, the RGB keyboard lighting doesn’t consciousness wholly necessary, but we appreciated the colorful splash this provided to an different acheronian aesthetic. 

It doesn’t consciousness inexpensive successful immoderate sense, and the ports are good placed. On the close side, there’s an audio jack, a USB 3.0 port, 2 type-c cablegram ports, and an ethernet port. On the left, there’s different USB 3.0 and type-c port, alongside an HDMI larboard susceptible of outputting 8K astatine 60Hz, oregon 4K astatine 120Hz. 

It felt similar capable options without going overboard, and there’s nary ports circular the backmost oregon successful immoderate awkward positions truthful if you’re readying connected getting connected, the 12UGS volition get the occupation done fine.

Thinking of that HDMI port, we tried hooking this up to a LG Nanocell 86 utilizing a HDMI 2.1 cable, a TV that supports up to 120Hz refresh rate. We came distant impressed by the output prime here. It helps springiness the 12UGS suitable flexibility you’d expect from a gaming laptop, should you ever privation to play disconnected a bigger screen.

Otherwise, the in-built show was suitably specced. The MSI Stealth GS66 12UGS tin tally UHD astatine 4K solution with 120Hz, 1440p astatine 240Hz, oregon 1080p astatine 360Hz. You won’t find galore games which presently deed 4k and 120fps, but the representation prime looked beauteous sharp.

Sadly, this laptop doesn’t enactment HDR extracurricular video streaming, truthful games deficiency that finer extent successful colors. It’s unfortunate but adjacent without it, there’s inactive a beardown show here, 1 that holds up nicely against nonstop sunlight.

Like galore laptops, this one’s besides packing a built-in webcam supra the display, though there’s nary privateness flap and, considering what the 12UGS offers elsewhere, it’s amazingly debased spec too. This webcam’s susceptible of hitting 30fps astatine 720p resolution, truthful it’s capable for modular video calls oregon conferencing but if you’re idiosyncratic looking to watercourse connected Twitch with this camera, you’d beryllium amended disconnected picking up a dedicated webcam

 MSI Stealth GS66 12UGS: Performance 

  • Runs exceptionally well 
  • Gets particularly large and hot


Here’s however the MSI Stealth GS66 12UGS performed successful our suite of benchmark tests:

3DMark: Night Raid: 34609; Fire Strike: 22292; Time Spy: 9732; Port Royal: 5968.
Cinebench R23 azygous core: 1764 points
Cinebench R23 Multi-core: 14251 points

PCMark 10 (Home Test): 7623 points
PCMark 10 Battery Life: 5 hours and 10 minutes
Battery Life (TechRadar movie test): 5 hours and 28 minutes
Total War: Warhammer III (1080p, Ultra): 61fps; (1080p,
Low): 134 fps
Cyberpunk 2077 (1080p, Ultra): 85 fps; (1080p, Low): 114 fps
Dirt 5 (1080p, Ultra): 75 fps; (1080p, Low): 124 fps 

Starting with the basics, this keyboard felt suitably comfy to usage erstwhile typing away. If each you’re searching for is simply a laptop for day-to-day admin, determination isn’t overmuch other the MSI Stealth GS66 12UGS tin connection here, unless you really similar RGB lighting. At 14.5cm wide, a sizeable trackpad besides works nicely, adjacent if we yet preferred utilizing a wireless mouse. 

For axenic power, we tested this laptop betwixt Dirt 5, Cyberpunk 2077, and Total War: Warhammer 3. Thankfully, the Stealth GS66 12UGS consistently deed implicit 60fps, adjacent connected ultra settings. It doesn’t ever comparison favorably to different competitors, hitting a little FPS number connected Warhammer III to the Razer Blade 15. But, if you’re aft a high-quality instrumentality for games similar Cyberpunk, ultra graphical settings tested much favorably. 

Unfortunately, it consistently fared worse than Razer’s enactment during our 3DMark tests, contempt those mixed benchmarks. While we didn’t trial Port Royal connected the different machine, Night Raid came successful astatine 34609 adjacent aft aggregate tests, a shocking 18k little than the Blade 15. Firestrike was overmuch closer, lone 2k disconnected astatine 22292, portion Time Spy closed this spread adjacent further, hitting 9732 for a astir 1k difference. 

Both laptops are utilizing the aforesaid Nvidia RTX 3070 Ti, but considering the Blade 15 uses an Intel i7 processor instead, this was surprising. Still, MSI’s latest is nary slouch and it’s backed up by immoderate high-quality speakers, which provided wide audio erstwhile playing games oregon conscionable listening to Spotify. 

There is 1 large caveat, unluckily - fixed the tiny abstraction these components are packed into, the 12UGS fans get loud, and blistery truthful effort to guarantee your determination is good ventilated erstwhile successful use.

MSI Stealth GS66 12UGS: Battery life 

  • Terrible artillery life 
  • Slow charging 

With its top-of-the-line hardware and large gaming performance, the MSI Vector GP66 12UH seemingly takes its newly-established rivalry with the Razer Blade 15 (2022) a tad excessively acold by outdoing the latter’s mediocre artillery life. 

The Vector GP66 hardly managed to compression retired a disappointing 2 hours 43 minutes during our PCMark10 artillery beingness trial and 2 hours 16 minutes during our FHD movie artillery test. In comparison, the Razer Blade 15 (2022) lasted six minutes and 27 minutes longer than the Vector GP66 successful some tests, respectively. 

Fast charging could person offered immoderate benignant of metallic lining, but unfortunately, this is not the lawsuit with the MSI Vector GP66. Throughout our galore tests we recovered that erstwhile successful use, the laptop tin instrumentality up to 2 hours to scope 100% artillery adjacent erstwhile performing the simplest work-related tasks.

As is the lawsuit with galore different gaming laptops, the Vector GP66’s abbreviated artillery beingness is apt the effect of its power-hungry CPU and GPU. 

Fortunately for MSI, its latest laptop is by acold not the lone 1 connected the marketplace with a artillery beingness of 3 hours oregon less, and considering the lukewarm reception that the Razer Blade 15 (2022) and the Lenovo Legion 7 (Gen 6) person received, being tethered to a charging cablegram doesn’t look to beryllium excessively overmuch of a dealbreaker wrong the gaming assemblage anyway.
