The Toshiba KIRAbook performed well overall, thanks to its 8 GB of RAM allowing for greater multitasking than other ultrabooks on the market with only half as much system memory. It blazed through word processing and similar tasks with ease, and could handle 10+ tabs of streaming YouTube and Twitch videos without slowing down at all.
Though the KIRAbook does not have a dedicated graphics processor, it still should be able to handle many games on low to mid graphics settings. However, don’t expect to do so while running many other programs in the background, as the performance will bottleneck with just the integrated Intel graphics.

The KIRAbook’s 4-cell Li-polymer battery lasted admirably. Under our rigorous testing conditions, which simulate heavy application, internet and screen use, the KIRAbook lasted about 5 hours. Considering the high-resolution screen and good processing power, this is a good score. In real-world sustained use, the battery should definitely exceed that time, however, since our testing is really pushing the limits of the battery.
Heat and Noise
The KIRAbook features two vents: one on the bottom right side, and another on the back of the chassis, facing towards the hinge. Running 10 tabs of HD Twitch and YouTube streams at once led to the area around the hinge-facing vent (including the bottom right corner of the screen) getting warm, but overall the device stayed cool. The bottom hardly heated up at all, with most of the heat being directed through the hinge vent. This means that the KIRAbook makes a good laptop computer in the literal sense, since this is far more intensive streaming than most users will do at once. All this ran perfectly silently as well.
