Alienware M14x



The good: The Alienware M14x, Dell's latest Alienware laptop, manages to pack amazing performance into a smaller-than-expected body with plenty of configuration options.

The bad: High-end configurations can be insanely expensive, and Alienware's laptop design is overdue for a refresh.

The bottom line: It's tough to find mobile PC gaming in a package that's neither too big nor too small. The Alienware M14x comes very close, with plenty of component options and a size that's hefty, but not backbreaking.

Typically, the difference between a 14-inch laptop and a 15-inch one is very slight, although we generally prefer the smaller of these two options for the sake of portability. When it comes to chunky gaming laptops, however, the difference can be more pronounced. While we wouldn't consider taking Alienware's 15-inch M15x laptop on the road, the new 14-inch version, unsurprisingly named the M14x, looks and feels a good deal smaller--even if it's still a beast compared with other 14-inch laptops.
For truly portable gaming, you'd want to stick with the popular 11-inch M11x, pretty much the only gaming ultraportable you'll find. But this new in-between size is enticing for those who want to take their games on a family vacation or business trip and still enjoy a reasonable screen size and generous 1,600x900-pixel screen resolution.
All this doesn't come cheap, and our review unit of the M14x costs $2,198, which includes a high-end Intel Core i7 2820QM CPU, an Nvidia GeForce GT555M GPU, 8GB of RAM, and a 750GB hard drive. Fortunately, more realistic configurations start at $1,199.

It's been a few years since Dell gave its Alienware lineup a makeover, and it's starting to show. Like the recent M11x, the new M14x has the same angular, almost automotive design as the 15- and 17-inch models of a few years ago. When we first saw it we thought it was a good step toward a more upscale feel, but since then we've seen a lot of sharp laptop designs that go even further toward a modern, minimalist look.
The M14x has the same automotive-inspired grille along the front edge (which is only for show, not ventilation), a slick edge-to-edge glass overlay on the display, and a matte black chassis (the exterior of our system was a matte red). It's distinctive, to be sure, and will feel comfortable and familiar to longtime Alienware fans, but we're also eager for something new, and hopefully a bit slimmer. At 1.2 thick and 6.5 pounds without A/C adapter, this is still an effort to haul around more than occasionally.
Alienware's FX lighting and settings control system is still here. It lets you set the color for the backlit keyboard and the other light-up parts of the system. Backlit keys can be essential while gaming, as a black-on-black keyboard can be tough to make out in the dark.
The keyboard has a more traditional tapered key design, rather than the wider, flat keys many laptop makers are partial to these days. The company has previously said that these tapered keys provide more space between the individual letters, which is better for first-person shooters, which make heavy use of the WASD keys. We're not sure we have a favorite key design for playing games, but it's an interesting theory.
Alienware has always had excellent touch pads, although much of the rest of the laptop industry is catching up in terms of size. The smooth, matte texture on the touch pad feels great under your fingers, and the two large, distinct mouse buttons are welcome. As with previous Alienware laptops, the touch pad is demarcated by a backlit ring, the color of which is selectable. A few touch-pad options, such as the size of the scroll bar, are controlled by an app called AlienTouch, but we didn't see any multitouch gestures such as two-finger scrolling.
On a 14-inch display, we'd expect to normally find a 1,366x768-pixel resolution, but for this much money, it's only natural to expect more. This model's native resolution is actually 1,600x900 pixels, which is a step up for gaming. We'd be tempted to ask for full 1,920x1,080-pixel resolution, but on a 14-inch screen text could become hard to make out. The built-in Klipsch speakers are as good as any we've heard in a laptop this size, and better than you'd find in many larger laptops.

While the ports and connections on the M14x are mostly standard stuff, we appreciate the triple video-out setup of HDMI, VGA, and Mini DisplayPort. Missing are high-speed data ports such as eSATA and Thunderbolt, but you do get a pair of USB 3.0 connections and optional WiMax.
You also get a potentially useful optional wireless display antenna, bundled with a Vizio-branded receiver, instead of the usual Netgear one (Alienware isn't using the more common Intel Wireless Display version of the technology). With that, you can hypothetically beam the action to a nearby big-screen TV, although we've been unable to make the connection yet, despite plenty of experience with the Intel/Netgear version of the technology. Check back for an update after we try some newer drivers.
The real star of the show is the quad-core Intel Core i7 2820QM processor, which sits at the top of Intel's current laptop lineup. It's a very powerful CPU, making it so that only recent very high-end systems, such as Apple's high-end 15-inch MacBook Pro, are comparable to the M14x in our benchmark tests. That said, it's more CPU than you probably need, and most M14x buyers should be fine taking the CPU down a few levels when selecting system options online to save some money.
The Nvidia GeForce GT555M is also a newer top-of-the-line part, and helped run our Unreal Tournament III test at 1,400x900-pixel resolution at 240.4 frames per second. Playing a more recent game, such as Mafia II, at 1,600x900-pixel resolution with very high graphics settings got us a more realistic number, 34.8fps. Either way, this is a zippy gaming machine and more than enough to handle the latest games (although not at 1,920x1,080 pixels, as the M14x's screen resolution doesn't go that high).

Asus K53E-B1

Asus K53E-B1
Design
The brown mocha frame seems very ordinary from a slight distance, but you can't fully appreciate the design until you put your hands on it. The plastic feels like synthetic leather, while the interior of the laptop is covered in aluminum—a nice play on two of the most commonly used materials in laptop designs. Though the design isn't the caliber of the aluminum-covered Apple 15-inch (Thunderbolt) and Dell XPS 15 (Sandy Bridge) ($1,785 direct, 4 stars), the K53E-B1 is a better looking laptop than the Samsung RF510-S01US ($750 street, 3.5 stars) and Dell Inspiron 15R-1847MRB ($730 list, 3.5 stars). At 5.8 pounds, it's only a few ounces heavier than the Apple 15-inch (5.5 lbs).
The 15.6-inch widescreen is adequately bright, with good viewing angles. Its 1,366-by-768 resolution is boilerplate, although you'll rarely see anything higher at this price. By comparison, the Dell XPS 15 (1,920-by-1,080) and Apple MacBook Pro (1,680-by-1,050) offer high-resolution screens. The full size keyboard is better than some of Asus's other models, namely the Asus N53SV-A1($1,099 list, 4 stars). I didn't detect any flexing in the center of the keyboard, and the chiclet keys were as responsive as those of the Dell XPS 15 and MacBook Pro. The keyboard is accompanied by an adjacent numeric keypad, albeit one with half-size keys. Loud clicking noises from the mouse buttons are my only complaints about this laptop; they can be heard from the other side of the room.
Features
The feature set isn't going to blow you away, but it's adequate for a desktop replacement. It comes with three USB 2.0 ports; the Samsung RF510-S01US and Dell XPS 15 raised the bar with USB 3.0 ports, which transfers data at ten times the speed of USB 2.0. It has a dual layer DVD burner and an HDMI port, in case you want to connect the laptop to an HDTV to watch a Netflix DVD. The 640GB, 5,400rpm hard drive has more than enough storage for the average videophile. Pricier systems like the Dell XPS 15 and Asus N53SV-A1 come with faster spinning 750GB, 7,200rpm drives. There's a standard Webcam for video chatting, along with a media card slot in the front bezel.

Performance
Asus K53E-B1The laptop is equipped with a 2.5GHz Intel Core i5-2520M CPU, a dual-core processor based on Sandy Bridge architecture. Granted it's no match for the quad-core variants found in the Dell XPS 15, Apple 15-inch, and Asus N53SV-A1, but it'll easily blow past any previous-generation Core i5 competitor. Case in point: The K53E-B1 dominated the Samsung RF510-S01US and Dell 15R-1847MRB, which run on previous-gen Core processors, in every single one of our benchmark tests. On our Adobe Photoshop CS5 tests, the K53E-B1 scored 3 hours 51 minutes, its 6GB of DRR3 memory helping it power past the Apple MacBook Pro (3:58) and Dell XPS 15 (4:06). This is a ferocious video and photo editing laptop.
All the Sandy Bridge laptops that have been tested thus far have powerful gaming chips. The K53E-B1 relies on integrated graphics, which, traditionally, have been written off in the gaming industry. But Sandy Bridge brings with it an integrated graphics chip that's many times more powerful (according to 3DMark06 and Crysis tests) than that of its predecessor, so it can handle many 3D games at base settings. If you want to max out every graphics detail, a discrete chip is still the way to go.
There are battery benefits that come with Sandy Bridge, although the K53E-B1's battery score of 6 hours 26 minutes in MobileMark 2007 wouldn't have been possible without a decent size battery (56WH). It's a bigger battery than the one found in the Samsung RF510 (48WH) and Dell Inspiron 15R (48WH), both of which scored 3:28 in the same test. More powerful laptops like the Dell XPS 15 (92WH, 6:58) and MacBook Pro (77.5WH, 6:43) temper their hardcore parts with much bigger batteries, yet their scores were only marginally better than the K53E-B1.
Rest assured the Asus K53E-B1 won't be the last desktop replacement with this kind of power and battery life. You will be seeing many other similar Intel Core processors and integrated graphics based on the Sandy Bridge architecture. Nevertheless, the K53E-B1 is priced accordingly, a solid performer, and beautifully designed. But the Apple MacBook Pro 15-inch (Thunderbolt) still rules this category.
