Design and construct
Last yr’s Alienware X15 R1 broke new floor in Dell’s premium pocket book line-up introducing an authentic design that swapped out its aspect ports for a rear port panel. It additionally supplied avid gamers a selection of Intel’s highly effective 11th-gen Tiger Lake processors, which is icing on the cake for these wanting a laptop computer with distinctive appears to be like in addition to efficiency.
The x15 R2 is a chip off the previous block, that includes the identical thrilling design, whereas additionally boasting equal {hardware} upgrades to the tune of Intel’s 12th-gen Alder Lake cellular processors, the newest Nvidia GeForce RTX 30 Series GPUs and quicker DDR5 RAM. I say “exciting design” as a result of the sloping rear port with Tron Ring and unit’s console-like show look otherworldly.
The R2’s twin shade scheme can also be placing. The exterior consists of a Lunar Light (pale gray), which distinguishes it amongst an ocean of predominately matte black gaming laptops. But flip the lid open and matte black is used, and to dramatic impact; it covers the entire floor, from the rounded outer edges to the skinny bezels, guaranteeing the beautiful QHD show actually pops out.
The outer floor can also be conveniently coated in a High Resistance Clear Coat to forestall stains. Both surfaces additionally conceal fingerprints extraordinarily effectively.

Sizing the laptop computer up, the x15 R2 measures 14.16 x 10.92 x 0.63 inches. Comparatively, that makes it bigger, however thinner than the likes of the 2022 Razer Blade 15 (13.98 x 9.25 x 0.67 inches) and the Dell G15 Gaming Laptop (14.07 x 10.74 x 1.2 inches). As Dell’s thinnest 15-inch gaming laptop computer, it slips soundly right into a laptop computer sleeve or a backpack.
The iconic Alienware styling we noticed on the 2021 Alienware x15 R1 additionally returns with vengeance. You’ll discover two RGB-lit alien head logos embedded within the chassis – one which sits atop the keyboard and doubles because the R2’s energy button, and the opposite positioned inches from the outside prime of the lid. These ship a way of mystique that can be effectively appreciated by avid gamers.

Below the panel that frames up in a 16:9 ratio, the phrase “Alienware” is inscribed in acquainted typography, whereas honeycomb formed perforations, which we’ve seen plenty of in gaming laptops this yr, beautify the laptop computer’s base, offering loads of eye-candy from entrance on. They additionally take up residence on its underside as helpful air vents for cooling.
The RGB lighting additionally units the x15 R2 aside, being a little bit extra refined than in some gaming laptops. I bought a kick out of the way it’s used to belie a form of alien intelligence befitting the laptop computer’s extraterrestrial theme.
For instance, the per-key lit keyboard lights up with full RGB colours upon start-up after which turns blue, simply as you’d anticipate the cockpit of some extremely superior alien spacecraft to do. The alien head adorned energy button additionally flashes from blue to yellow if you insert the AC adapter, two good touches that add to the laptop computer’s enchantment.
When it involves construct, the x15 R2’s chassis is constructed from magnesium alloy and feels very strong. Although, barely much less so than one other laptop computer we not too long ago reviewed the 2022 Razer Blade 17, a laptop computer that demonstrated virtually immovable rigidity all through.
This is shocking given the x15 R2’s weight, which is 5.2 kilos, noticeably heavier than the 2022 Razer Blade 15 (4.43 lbs) and the 15.6-inch Acer Nitro 5 (4.77 lbs). Is the X15 R2 flimsy? Not by any means. But its chassis may have been harder.
Keyboard and trackpad
The x15 R2’s Alienware X Series keyboard has all of the hallmarks of a premium gaming keyboard. It sports activities per-key RGB Alien FX backlighting that may be custom-made within the Alienware Command Center app. The keys, which characteristic giant keycaps and a decent 1.5mm journey, really feel gentle to faucet and reply shortly. Dell has included N-Key Rollover and Anti-ghosting applied sciences for improved accuracy within the warmth of battle.
The keyboard format is a fragile stability of give and take, in that it omits a numpad however provides full sized arrow keys that make skipping by menus quite a bit simpler. You’ll additionally discover standalone audio keys, together with mute, microphone and quantity keys that simplify management of media. However, half sized perform keys could take a little bit getting used to for those who’re a heavy consumer.

The backlighting appears to be like excellent, however all that spectacular illumination is reserved for the first symbols on keys solely. This means secondary symbols could be a little troublesome to see in low gentle circumstances.
Below the keyboard sits one of many smallest trackpads I’ve used. It measures simply 4.2 x 2.5 inches. Admittedly, trackpad sizes are a deeply private choice, however I’ve at all times discovered giant ones to be a little bit gradual in video games the place I’m not utilizing a mouse. The R2’s diminutive trackpad, nevertheless, permits your finger to traverse the complete size quite a bit faster. It additionally feels silky easy to the contact, so it will get full marks from this reviewer.
Display
Dell presents three flavors for the x15 R2’s show, two with FHD 1080p resolutions and both 165Hz or 360Hz refresh charges or a QHD 1440p show with 240Hz refresh price. All three choices sport Nvidia G-Sync and Advanced Optimus applied sciences.
With the show bench set excessive this yr by the Razer Blade 15’s OLED panel, I used to be significantly to see how our evaluate unit’s QHD 240Hz one would form up. Thankfully, the 100 p.c DCI-P3 IPS panel regarded and carried out a deal with in video games, producing vibrant wealthy colours, with surprisingly crisp element in pictures in addition to textual content.

Armed with Nvidia G-Sync, a 2ms response and the 240Hz refresh price, it nearly obliterated any stuttering, and enter lag, delivering buttery easy animation in video games like Far Cry 5 and Cyberpunk 2077.
A peak brightness score of 400 nits additionally offered wonderful distinction, displaying up deep blacks and full bodied gray tones that I used to be blissful to indicate off in group gaming periods – and that may absolutely be an asset in a content material creation context.
ComfortView Plus know-how is one other neat addition to the x15 R2’s panel that offered a little bit additional consolation for my eyes throughout lengthy play periods. It’s a built-in, always-on know-how that reduces blue gentle emissions. I by no means seen it working within the background, however I did discover my eyes have been rather less blurry after enjoying.
Webcam and audio
Gaming notebooks aren’t recognized for the standard of their cameras. The x15 R2 HD 720p Windows Hello IR suitable digital camera, nevertheless, does a passable job reproducing what’s in entrance of it.
It handles dimly lit rooms a little bit higher than overhead lights that may distort pictures a little bit and produce glary halo results. I discovered this completely acceptable for gaming chats the place I used to be largely in a dimly lit rooms anyway.
Testing the x15 R2’s audio system revealed a comparatively clear, crisp audio that was altogether shocking contemplating the laptop computer’s pencil skinny 0.63-inch chassis. They additionally dealt with bass notes remarkably effectively. Unlike the R1, the x15 R2 packs a secret weapon within the type of Dolby Atmos spatial audio know-how, that delivers a noticeable immersive high quality to sound.
Connectivity
The x15 R2 ticks off no less than one port for every of your diversified I/O wants, together with USB 3.2 Gen 1 Type-A, USB 3.2 Gen 2 Type-C and Thunderbolt 4 ports. Although, with so many gadgets to plug into my laptop computer today – mouse, headphones and others – I did discover myself wishing I had one other USB- C port at my fingertips.
This was simply fastened by plugging in a USB-C Hub. The x15 R2’s Type-C USB will also be become an Ethernet port with the conveniently equipped USB-C to RJ45 adapter, so you may nonetheless get the quickest connection, if nothing however the most effective will do.
Like the R1, the x15 R2’s ports are housed in a panel in the back of the laptop computer. One benefit of that is you may discreetly conceal unpleasant cords or dongles. Although, a small peeve is you’ll must bodily get up and lean over the again of your laptop computer, or spin it round to face you to plug something in. Even then, the R2’s Tron Ring RGB gentle casts a darkish shadow, making them troublesome to see and not using a lamp.
