Gaming laptops with huge 18-inch display screen sizes are considerably uncommon. Maingear’s first 18-incher, the Ultima 18, presents as much as 192GB of DDR5 reminiscence and 4 M.2 SSD choices, in addition to what you’d count on: an Nvidia GeForce RTX 5090 cellular GPU.
It isn’t fairly the tip-top of cellular gaming laptops, because the Intel “Arrow Lake” Core Extremely 9 275HX is only one 100-MHz step down from the Intel Core Extremely 9 285HX Intel launched at CES 2025, but it surely does retain an edge over the MSI Crosshair 18 HZ AI that MSI launched at Computex 2025, with “simply” a GeForce RTX 5070 inside.
Clearly, an 18-inch gaming laptop computer is just not for the weak of pockets, and the Ultima 18 is priced accordingly: it begins at $3,599 and can most likely climb precipitously upwards from there.
Along with the 5.4GHz Core Extremely 9 275HX processor and 175W, 24GB RTX 5090 (or 5080), the laptop computer presents as much as a whopping 192GB of DDR5 DRAM and 4 M.2 MVME SSDs. That’s par for many competing laptops of this measurement, although you’ll clearly need to pay significantly additional to populate all of them. Maingear tells us that these SSDs embrace PCIe Gen 5 capabilities, although it’s not clear if the entire slots will boast that pace or not.

The 18-inch show is a 3840 x 2400 matte show with 100% DCI-P3 shade help, 7ms refresh charge, and refresh charges of as much as 200Hz. It’s a standard IPS show, not miniLED, which a Maingear consultant stated labored finest with the cellular RTX 5090 GPU.
On the aspect are two Thunderbolt 5 ports. Sadly, Maingear was the seller that graciously provided us with our first Thunderbolt 5 check mattress, which apparently break up the controller between two ports, leading to diminished efficiency. We will hope that Maingear solved the issue this time round. In any other case, there are devoted HDMI 2.1, two USB-A ports, microSD, and two 2.5GBit Ethernet ports, which is a bit uncommon. Wi-Fi 7 and Bluetooth 5.4 present wi-fi connections.

Maingear particularly referred to as out Clevo as its manufacturing accomplice, and famous that it has a “steel lid” and palm relaxation, however Maingear didn’t present additional particulars.
Don’t count on this laptop computer to something near skinny and lightweight; it weighs a backbreaking 8.8 kilos, although Maingear claims it will possibly match inside a backpack. Inside it’s a 98Wh battery, plus audio (two drivers, two tweeters and even a subwoofer powered by Sound Blaster Studio Professional 2. The laptop computer ships with a “backpack pleasant” 330W charger, although USB-C charging can be utilized in a pinch — most likely not for powering video games, although.
Maingear didn’t present any efficiency traits, although the laptop computer ships freed from bloatware and with the Management Heart management software program that permits for changes to be made.
