To state the obvious, the GS66 Stealth is the direct successor of the GS65 Stealth that has seen two iterations since it was first introduced back in 2018. Unlike its predecessor, the GS66 shows off a new and completely different chassis. Gone are the honeycomb grills and rounded hinges that were once built into the side, as is the shimmering blue body and gold accents. In its place, a single, solid, all-black motif envelops the notebook from head-to-toe. Another difference in design is the way the spine sticks out; it’s quite obvious when the notebook is closed, but when in use, you actually wouldn’t know it’s there.

For its display, the GS66 Stealth employs a 15.6-inch Full HD panel. Naturally, it’s got a high refresh rate too, but instead of 144Hz or 165Hz, MSI has seen fit to set it at an eye-watering 300Hz. Mind you, it’s not variable and while we understand the benefits such a high refresh rate provides Esports gamers, there aren’t a lot of titles – Esports or triple-A – that are capable of achieving and sustaining those numbers. Underneath the hood, the GS66 Stealth is, yet again, packed to the rafters with some of the most powerful hardware on the current market. On paper, the notebook is packing a 10th generation Intel Core H-series CPU, 16GB DDR4 RAM, and an NVIDIA GeForce RTX GPU. And before you ask, yes. It does come with an NVMe SSD.

The biggest update to this notebook, however, is the 99.9WHr battery that powers it; while the unit we saw was an engineering sample, MSI assured us that the new battery will be able to provide users with more than 10 hours of continuous use on a single charge. Also, if you’re wondering why the brand stopped at that number, it’s because that is the largest battery size that is legally allowed on planes. Any bigger, and you wouldn’t be able to bring it on-board a plane.

As to its availability, MSI says that the GS66 Stealth will be available sometime this year, although it didn’t provide exact dates or pricing for the notebook.
