We compared the P50t to other laptops with better-than-HD displays. Those systems, including the Razer Blade 14, 15-inch Retina MacBook Pro, and Dell XPS 15, all share Core i7 CPUs, and some form of discrete graphics card. In our benchmark tests, the P50t was near the top or middle of the pack in application tests, but its AMD R9 GPU is better suited to video rendering than 3D gaming, and it turned in acceptable but unimpressive frame rates in games at the standard 1,920x1,080 resolution.
Of course, we had to try playing some games at the full 4K native resolution of the screen, but this is an idea the hardware is not yet ready for. Metro: Last Light and Bioshock Infinite ran under 10 frames per second at 4K. Skyrim chugged unpleasantly, even with detail settings at low. But, a couple of older games, including Call of Duty: Modern Warfare 3, were very playable.
Pushing that many pixels has to have an effect on battery life. Playing a standard 1080p video file, the P50t ran for 2:52, which is a low score for any current 15-inch laptop and less than the other higher-res systems we tested, sometimes by a large margin. We ran a second test using a 4K resolution video file to see if that would make a difference (perhaps by hitting the GPU harder), and that test run scored two hours even, which is about one-third less than our standard test.
Even without the first-on-the-market 4K display, the Satellite P50t is a very nice premium 15-inch laptop, with a big touchpad, large hard drive, and decent AMD graphics. Would I pay $1,599 for that? Probably not, but it's not completely out of the ballpark.
Adding that amazing-looking 4K screen is a big extra and definitely makes this a conversation piece, while still being a useful all-around midsize laptop. The only real letdown here is battery life, which may be a trade-off you're willing to make for first-on-the-block bragging rights if you want to be a 4K early adopter.
