Reviews for the Lenovo Y50-59432235

Asking for a 4K display in a 15-inch laptop may be a bit of stretch, and we've only seen a couple of other examples to date. In this case, the included graphics card isn't up to the task of high-end UHD gaming, but you still get the benefit of a better-looking screen, plus touch for all those times when you're not playing a game (trust me, a touchscreen makes Windows 8 much more tolerable).

Model:
Despite being categorized as a gaming laptop, the Y50 features rather mid-range hardware compared to the other recently released gaming laptops. Lenovo's latest laptop cuts off a lot of the bulk compared to its predecessor of the Y510p series, and ends up being a lot lighter at only 2.4 kg and barely 2.54 cm thick. It has a 15.6 inch screen, which is pretty decent for the casual laptop user, but slightly lacking for a gaming laptop range where 17 to 18 inch screens are more common. Subwoofers are at the underside of the laptop and make for a great sound.
Being in the gaming laptop category, it boasts powerful hardware such as an Intel Core i7-4700HQ processor, 16 GB RAM, and a GTX 860M Nvidia graphics card. The latter can smoothly run the latest new games in medium to high settings. With a battery life of 2 to 3 hours in use, it is able to outlast most gaming laptops, but not by much. The Lenovo Y50 might not be the most powerful laptop in the market, but it runs most of the latest games and programs fairly well and is definitely one of the most value for money gaming laptops in the market.
NVIDIA GeForce GTX 860M: Upper mid-range graphics card from the GeForce GTX 800M series.
Modern games should be playable with these graphics cards at low settings and resolutions. Casual gamers may be happy with these cards.

Intel Core i7: The Intel Core i7 for laptops is based on the LG1156 Core i5/i7 CPU for desktops. The base clock speed of the CPUs is relatively low, but because of a huge Turbo mode, the cores can dynamically overclock to up to 3.2 GHz (920XM). Therefore, the CPU can be as fast as high clocked dual-core CPUs (using single threaded applications) but still offer the advantage of 4 cores. Because of the large TDP of 45 W / 55 W, the CPU is only intended for large laptops.
4710HQ: Haswell-based quad-core processor clocked at 2.5 GHz with Turbo Boost support up to 3.5 GHz. Offers an integrated HD Graphics 4600 GPU and a dual channel DDR3 memory controller.» Further information can be found in our Comparison of Mobile Processsors.
