Windows 10 chase: Now Samsung unveils 4K display ATIV Book 9 Pro and new 2-in-1

Samsung enters the Windows 10 game with two new metal-finished touch-display laptops.

Samsung has taken the wraps of two new Windows 10 laptops, introducing the ATIV Book 9 Pro, its first 4K display notebook, and the new two-in-one Ativ Book 9 Spin.

The two laptops are the newest members of Samsung's high-end and premium-priced Ativ Book 9 family, with both set to go on sale from the beginning of November in the US.

The 15.6-inch display ATIV Book 9 Pro is a "powerhouse", according to Samsung, and that holds true at least compared with the 12-inch ATIV Book 9 released earlier this year.

Besides the Ativ Book 9 Pro's 4K touch display, at a resolution of 3,840 x 2,160 pixels, it's running NVIDIA's GeForce GTX 950M graphics processor supported by a four-speaker set-up.

The Pro ships with 8GB RAM, a 2.6GHz Intel Core i7 processor, and 256GB solid-state drive (SSD). As expected with a premium device, it's got a backlit keyboard, and plenty of ports including one Type C reversible USB port, three USB 3.0 Type A ports, a 4K HDMI output, mic port and SD card reader.

Finally, the new Windows 10 notebook weighs in at 4.45 pounds (1.81kg), or a tad lighter than the 15.4-inch MacBook Pro.

A little troubling, on paper at least, is that the battery lasts up to 6.5 hours, falling 2.5 hours short of the MacBook Pro's battery longevity.

The 13.3-inch display two-in-one ATIV Book 9 Spin shares the same RAM and storage specs with its larger Windows 10 sibling, though Samsung eschews the 4K display for a QHD+ display at a 3,200 x 1,800 pixel resolution and instead uses a slightly slower 2.5GHz Intel Core i7 processor, and Intel's HD Graphics processor.

The Spin also lacks the USB Type C port of the Pro, but still includes three USB 3.0 ports, an HDMI port, and a microSD card reader. The smaller display device comes with two speakers, while its battery will last up to 7.3 hours, according to Samsung.

Samsung's Spin joins a growing number of contenders in the two-in-one space, including Microsoft's Surface hardware, Lenovo's Yoga 3 Pro, HP's 13-inch Spectre x 360 and Asus's budget Transformer Book T100HA.

Like them, the Spin's display can be removed and used as a tablet or swivelled on a 360-degree hinge for traditional laptop mode or in a tented-screen mode, with all three modes supporting touch.

Finally, on price Samsung as usual comes at the higher end of recently-introduced Windows 10 laptops. The ATIV Book 9 Pro will retail for around $1,600 while the ATIV Book 9 Spin will cost $1,400.

In the US, the two devices will be available exclusively from Samsung's website and Best Buy.
