ASUS officially introduces a pair of new Zenbooks with Windows 8.1

Among them is a souped up version of the existing Zenbook UX305 as well as the brand new Zenbook Pro UX501.

The big difference to the existing Zenbook UX305 is the inclusion of a QHD+ 3200 x 1800 resolution touchscreen display, 8GB of RAM and a 512GB SSD drive. The same specs have already been made public in the limited edition Crystal White version recently, but it's good to see a less limited version also going on sale.

The Zenbook Pro UX501 is a different animal entirely. There's no Core M, here. This one's built for performance. Inside the UX501 is a 4th-generation Intel Core i7 CPU, 16GB of RAM and upto 512GB of PCIe SSD storage. Out front you'll be looking into a 4K touchscreen display and graphics power is taken care of by an NVIDIA GeForce GTX 960M GPU with up to 4GB of GDDR5 video memory.

No pricing or launch information is available at this time, but needless to say, we can't wait to get our hands on one.

Check out the full press release below.

World's slimmest 13.3-inch QHD+ ultraportable — ASUS ZenBook UX305

New York, NY (May 18th, 2015) - ZenBook UX305 has a subtle and refined new shape that incorporates the DNA of the classic ZenBook. It features an elegantly-tapered design with smooth, comfortable edges and diamond-cut highlights that subtly emphasize the sleekness of the 0.48inch-thin case — and it weighs just 2.64lbs. The UX305 is available in crystal white, champagne gold and obsidian stone black.

ZenBook UX305 is powered by an Intel Core™ M processor, a remarkably power-efficient processor designed for ultra slim devices that effortlessly delivers smooth performance. In combination with up to 8GB of RAM and an ultra-fast up to 512GB SSD, UX305 delivers impressive all-round performance for daily computing.

A stunning ultraportable needs a display that's out of the ordinary, so ZenBook UX305 is fitted with an ultra-sharp 13.3-inch in-plane switching (IPS) multi-touch display with an up to QHD+ resolution of 3200 x 1800 pixels and wide viewing angles. This display has five times (5X) the resolution of a standard HD display, and features an amazing pixel density of 276PPI for crisp, vivid and lifelike images and video.

With 300cd/m2 brightness, a contrast ratio of 770:1 and an ergonomic anti-glare coating, blacks are deep, whites are stunningly pure, and the wide color gamut (72% NTSC) ensures accurate colors.

ZenBook UX305 is also equipped with three SuperSpeed USB 3.0 ports for data transfers that are up to ten times (10X) faster than USB 2.0. One of the USB ports supports ASUS Charger+ technology for rapid recharging of mobile devices. A USB-to-Ethernet adapter is bundled with UX305, along with a mini DisplayPort-to-VGA adapter — enabling easy connection to an external monitor.

A perfect blend of power, elegance and performance — ASUS ZenBook Pro UX501

At the heart of ZenBook Pro UX501 is the ultra-powerful quad-core Intel Core i7-4720HQ processor, providing effortless performance for any task. With a massive 16GB of RAM, multitasking is super-smooth and there's plenty of processing horsepower in reserve for even the most intensive number-crunching tasks.

ZenBook Pro UX501 also features the amazing new NVIDIA® GeForce® GTX™ 960M graphics-processing unit (GPU) for gaming-grade graphics performance. With up to 4GB of fast GDDR5 video memory, users enjoy silky-smooth 4K/UHD video playback, effortless 3D rendering, and immersive gaming with ultra-high frame rates.

ASUS VisualMaster displays set the standard for laptops, incorporating some of the very latest technology to give users unrivaled visual clarity and detail. ZenBook Pro UX501 has a 15.6-inch multi-touch display with a pin-sharp 4K/UHD 3860 x 2160 resolution — four times (4X) higher than Full HD — and an incredible pixel density of 282PPI for stunningly-detailed and lifelike images. IPS technology with wide 178-degree viewing angles ensures that colors and contrast are not degraded from any viewing position.

Ultra-fast storage is essential for fast boot times and effortless file operations, so ZenBook Pro UX501 is available with the world's fastest SSD. With a PCI Express® (PCIe®) x4 interface and up to 512GB capacity, the read/write speeds of up to 1400MB/s are twice as fast as competing PCIe x2 models, and 16 times (16X) faster than common SATA 6.0Gbit/s hard disk drives. And with no moving parts, ZenBook Pro UX501's SSD is both reliable and totally silent.

An advanced thermal-management system combined with ZenBook Pro UX501's 96Wh lithium-polymer battery means that users won't need to find a mains-power outlet for up to six hours — and even beyond..
