Tech Trend 247

Razer's 12.5-inch Blade Stealth set out to reimagine thin and light Ultrabooks earlier this year, and it did. 

The company's now refreshing the Windows 10 machine with a seventh-generation Intel Core i7 processor and longer battery life.

The Blade Stealth still starts at $999 in the U.S. and is available immediately from Razer's online store, and on Amazon and Microsoft stores from later this month. 

Performance upgrades 

As the smallest and lightest Blade laptop in Razer's lineup, the Blade Stealth is not designed specifically for performance gaming and comes without the $399 Razer Core external graphics accelerator (and graphics cards sold separately), but the new internal upgrades should make it a little more powerful if you want to game at lower settings. 

The screen's still the same 12.5-inch touchscreen available in QHD resolution (2,560 x 1,440 pixels) and UHD 4K (3,840 x 2,160 pixels), with 100 percent Adobe RGB color saturation on the latter. 

And, of course, the Chroma keyboard still glows in an insane 16.8 million configurable colors.

Here's all the new stuff you get:  Seventh-generation Intel Core i7-7500U Dual-Core Processor (2.7GHz/3.5GHz), Intel HD Graphics 620 graphics, 128GB/256GB/512GB PCIe SSD (QHD screen model) or 512GB/1TB PCIe SSD (UHD 4K screen model), up to 16GB of LPDDR3-1866MHz RAM and a larger 53.6 Wh battery that will provide up to 9 hours of battery life (about 15 percent longer than the original Blade Stealth). 

For ports, it's still got a Thunderbolt 3 USB-C port, two USB 3.0 ports, HDMI and headphone jack.
