Written by Ehsan Batt

The Alienware X15 introduced at CES 2015 was a shocker in several aspects, offering all the lovable qualities of Alienware in a new style.

The Alienware X15 R2 has been released in quick succession to keep the gaming laptop in line with the latest technology and graphical power. Housing the latest Skylake processor from Intel, the Alienware X15 R2 comes in an identical chassis, which barely leaves out any room for complaining. Read our full review below.

Design and Build

Maintaining a certain amount of uniformity in its design, the Alienware X15 R2 inhibits the identical design properties of its 13, 15 and 17-inch siblings. The silver-grey lid casing of the laptop gives off a metallic look but is actually a compound created by carbon-fiber and polymer, which gives it a good amount of rigidity, while keeping it fairly lightweight as well.

From the lid to the base, each aspect of the Alienware X15 R2 offers stability, while the thin rubberized coating on the keyboard deck makes it comfortable for long gaming sessions. The weight of the laptop is 3.2kg, which is reasonable considering its 15-inch form factor.

What does put the Alienware X15 R2 above the rest of the gaming laptops is the ample amount of illumination on the lid, as well as the keyboard deck. Two illuminated lines are drawn towards the glowing Alienware logo, while the keyboard and the touchpad come with multiple colors, owing to the AlienFX tool that comes with the machine.

The Display 
The 15.6-inch Alienware X15 R2 comes equipped with a Full-HD IPS display panel. The brightness of the display has been advertised as 220 nits, but the real-time score suggests an average score of no more than 200 nits. The low brightness, despite the anti-glare coating on the screen, does not enable the users to view the laptop screen comfortably outdoors.

While the brightness is fairly low, the color contrast ratio of 950:1 and black value of 0.19 cd/m2 are decent enough for rich color reproduction. The screen is able to cover only 60% of the sRGB color gamut, which makes it less favorable for professional video editing and graphic designing. The viewing angles are excellent, with barely any distortion when the screen is viewed from different sides, owing to its IPS display.

Keyboard and Touchpad
Alienware is known for its attention to detail, and the keyboard used in the Alienware X15 R2 is an example for the competition to follow. The keyboard sacrifices the Numpad to provide the users with a dedicated macro field, which can be easily configured, while the four-zone illumination enables you to add a splash of colors to the keyboard. The keys are decently sized, offering crisp strokes while being relatively soft and quiet.

The touchpad of the Alienware X15 R2 measures 10.5cm x 10.5cm, and provides high precision and a smooth surface to help you navigate effortlessly. The fairly large surface of the touchpad comes with backlight illumination, whose color can be easily customized along with the other illuminating aspects of the laptop. The left and right-click buttons below the touchpad, and offer a sturdy, yet soft click mechanism.

Under the Hood

There are several different configurations offered by Dell, but all of the Alienware X15 R2 models come equipped with the latest 6th generation Intel processor. The reviewed version (Y5185A2AU) of the Alienware X15 R2 comes fitted with an Intel Core i7-6700HQ quad-core processor, based on the latest Skylake micro-architecture. With a base clock speed of 2.6 GHz, the Turbo Boost technology from Intel enables overclocking to 3.5 GHz.

The system comes with 8GB DDR4 RAM, which can be upgraded to 16GB. While the CPU and ample of RAM are enough to push the machine forward with sheer power, the system remains less snappy than others. Available in multiple storage configurations, the base version of the Alienware X15 R2 comes with no SSD storage, which puts all the weight on the 1TB HDD that it comes fitted with.

Gaming Performance

The Alienware X15 R2 is available with different GPU options as well, while the reviewed version comes with the NVIDIA GeForce GTX 965M GPU, with 2GB DDR5 dedicated graphical memory. Although the processor is an upgrade over the previous model, the slow HDD storage does affect the gaming performance a bit, while the GTX 965M is not the fastest contender either.

The gaming machine is capable of taking almost all of the titles of the previous year and is able to withstand the high requirements of many upcoming games as well. For instance, the Alienware X15 R2 runs smoothly at 60 – 70 frames per second when playing games such as GRID: Autosport, Civilization: Beyond Earth, and Sims 4. However, the frame rate drops to half when games such as GTA V, Assassin’s Creed Unity, and Far Cry 4 are played on high to ultra settings.


• Sophisticated design and robust chassis for durability.
• Attractive illuminations all around the gaming laptop.
• Powerful performance with extended overclocking capability.
• Fairly quiet and cool, even under pressure.


• The IPS display comes with low brightness.
• No SSD storage by default is available with the laptop.

The Final Verdict 

The Alienware X15 was introduced as a new-age gaming laptop that comes with the performance of a beastly machine, with extraordinary design elements. The Alienware X15 R2 continues to build on that legacy, with minor improvements along the way, and significant hardware upgrades to keep it prepared for competition.

The reviewed version of the  15 R2 (y5185a2au) has every bit of quality to justify the price, but the hardware does fall short. For instance, the powerful processor is not paired with a zippy SSD storage by default, which is a bare necessity for any modern laptop these days. The GTX 965M might be powerful enough to take on the latest games at high settings, but there are successors (GTX 980M) ready and available at a similar price.
The Alienware X15 R2 is unbeaten in terms of quality and is well supported by the powerful performance of its hardware, but does miss out o a couple of features that restrict it from being the absolute best.
