The Alienware x17 R2 was Dell’s 17-inch flagship gaming laptop for 2022, and in 2026 it makes sense only as a renewed buy at a steep discount. It squeezed Intel’s 12th-generation Core processors and graphics up to the Nvidia GeForce RTX 3080 Ti into a chassis just 0.84 inches thick, with a striking white finish and an optional mechanical keyboard. This Alienware x17 R2 review covers its design, display options, performance, cooling, and battery life according to major reviewers, and explains which current Alienware models and 16 to 17-inch gaming laptops on Amazon replace it in 2026.
Quick verdict: The Alienware x17 R2 delivered top-tier gaming performance, a gorgeous design, and one of the best keyboards on any laptop. It’s also heavy, runs hot, and lasts under an hour when gaming on battery. Dell has discontinued it, so buy one only renewed at a steep discount, or step up to the Alienware 16 Area-51. Check the Alienware x17 R2 price on Amazon.

Which Alienware 17-inch laptop is this?
Alienware sold two 17-inch gaming laptops in 2022: the thin x17 R2 and the thicker, cheaper m17 R5, which used AMD Ryzen 6000 processors. This review covers the x17 R2, identifiable by its white Lunar Light finish, rear port panel, and Cryo-Tech cooling. Both were the last 17-inch Alienware laptops. In 2023, Dell replaced them with the 16-inch x16 and m16 and the 18-inch m18 (see our Alienware m18 review for that larger sibling).
Design and build
The x17 R2 marked a shift away from Alienware’s bulky, heavily lit designs. Its magnesium alloy and aluminum chassis comes in Lunar Light white, with a glowing alien head logo and a lighting ring around the rear vents. At 0.84 inches thick, TechSpot found it slimmer than top Asus gaming laptops and barely thicker than the Razer Blade. It’s still a big machine, though, and Tom’s Hardware noted it’s larger and heavier than many rivals.
Almost every port sits on the back, which keeps cables tidy on a desk but makes plugging in a flash drive awkward. TechSpot also found the bright rear lighting made the ports hard to see.
Keyboard and touchpad
Dell offered two keyboards. The standard X-Series ultra-low-profile keyboard works well, but the highlight is the optional CherryMX ultra-low-profile mechanical keyboard, a roughly $50 upgrade. Laptop Mag called it comfortable and clicky, while Tom’s Hardware praised the switch feel but heard a metallic ping on some keys. There’s no number pad. Instead, a column of extra keys sits to the right, handling volume and mute, and you can program several function keys as macros.
The touchpad is large enough for Windows gestures, though it lacks a backlight. Most gamers will use a mouse anyway; a lightweight option such as the Razer Viper Mini Signature Edition suits a desktop setup.
Display options
Dell offered five 17.3-inch panels, so the experience depends heavily on your configuration. Competitive players gravitated to the 1080p 360Hz screen, which Laptop Mag measured at 325 nits with 76 percent of the Digital Cinema Initiatives P3 (DCI-P3) color space, below average for a premium gaming laptop. TechSpot advised against the 480Hz option. The 4K 120Hz panel with Nvidia G-Sync suits creators and single-player games, while the QHD 165Hz option offers the best balance of sharpness and speed for most people.
Performance
With a Core i9-12900HK and RTX 3080 Ti, the x17 R2 was one of the fastest laptops of 2022. Laptop Mag recorded 107 frames per second (fps) in Shadow of the Tomb Raider and 117 fps in Grand Theft Auto V at 1080p, and a 4K-to-1080p video transcode in 4 minutes and 45 seconds, far quicker than the category average. Two SSDs in a redundant array of independent disks (RAID 0) setup hit about 2,268 megabytes per second in Laptop Mag’s file transfer test.
It wasn’t untouchable. Both Laptop Mag and Tom’s Hardware found that the MSI GE76 Raider, with the same graphics chip, edged it out in most gaming tests. TechSpot also saw multithreaded CPU clocks settle at 3.9 gigahertz under sustained load.
Cooling, heat, and noise
Alienware’s Cryo-Tech system uses four fans and Element 31, a gallium-silicone thermal interface material that moves heat from the processor more efficiently than standard paste. TechSpot called the results pretty solid and measured a peak of 46 decibels in performance mode, quieter than many gaming laptops. Laptop Mag recorded 115 degrees Fahrenheit on the underside during gaming, and TechSpot found the metal above the keyboard too hot to touch for long. A laptop cooling pad from Amazon helps during long sessions.
Battery life
Battery life is the x17 R2’s weakest point. Its 87Wh battery lasted 2 hours 58 minutes to 3 hours 7 minutes in web browsing tests from Laptop Mag and Tom’s Hardware, and TechSpot got 3 hours 52 minutes of video playback at half brightness. Gaming on battery lasted under an hour in every test, and under 43 minutes in TechSpot’s. Treat this as a desktop replacement and keep the charger nearby.

Alienware x17 R2 successors in 2026
Alienware dropped the x and m names in 2025. Its lineup now centers on the 16-inch and 18-inch Area-51 flagships and the more affordable Aurora models. According to Windows Central, Dell refreshed them in March 2026:
- Alienware 16 Area-51: The x17 R2’s spiritual successor, with up to an Intel Core Ultra 9 290HX, an RTX 5090 laptop GPU, and a 16-inch QHD+ anti-glare organic light-emitting diode (OLED) display at 240Hz. Dell listed it at $3,149.99 on sale.
- Alienware 16X Aurora: A thinner midrange model that now offers up to an RTX 5070 Ti and the same 240Hz OLED option, from $1,699.99 on sale.
- Alienware 16 Aurora: The entry model, with a Core 7 240H, up to an RTX 5060, and a 1600p 120Hz screen. Notebookcheck found it a solid budget pick at about $1,100 to $1,300, though its panel shows ghosting and it drops Thunderbolt and G-Sync.
If you want the biggest screen, the Alienware 18 Area-51 continues the m18’s role.

Who should buy the Alienware x17 R2?
Buy a renewed x17 R2 if you want a 17-inch screen, love mechanical keyboards, play mostly plugged in, and find one for well under the price of a new RTX 50-series laptop. Skip it if you need battery life, portability, or a warranty-backed machine for the latest games. In that case, the Alienware 16 Area-51 or 16X Aurora makes more sense.

Final verdict
The Alienware x17 R2 combined flagship power, a striking slim design, and a superb mechanical keyboard, but heat, weight, and short battery life always held it back.
