Lenovo and its new plans to take over the (gaming) world!

Lenovo revamped its Y Series, now also referring to it as Legion. Therefore, main models which are released recently using the Intel Kaby Lake and the GeForce 10 series graphics. The units that they showcased was the Lenovo Y Series Y720 and the Y520. As you would expect with any manufacturers, Lenovo has a plan.

The company started by saying currently Lenovo has 29.7% market share in gaming and therefore it is aiming towards 5 million to 7 million gamers in India. Lenovo said that that the millennial PC gamers aged 31 are the key target for a variety of reasons mentioned above. Apart from the revamp in branding resulting in newer CPU and GPU architecture, its concentrating on storage performance and in-house utility called Nerve Sense. Some of its functions looked promising, but just having a hands-on experience in a press launch wasn’t an ideal place to test and check out everything. Thankfully, the Lenovo’s PR team let me take the Y520 back to Mumbai and see how it performs.

Configuration Overview- Lenovo Y520-15IKBN

The design of the Y520 is made around the shell which houses a 15.6″ LCD panel. The specific SKU is the Lenovo Y520- 15IKBN. This build uses a Kaby Lake-based quad-core Intel Core i7-7700 HQ clocked at 2.8 GHz base clock with Intel HM175 chipset and a GTX 1050 Ti 4GB GDDR5 clocked at 1493 MHz/1620 MHz base/boost clock. While this uses the same desktop-grade discrete graphics chip, the reference clock speed for the GTX 1050 Ti is 1290 MHz/1392 MHz base/boost clock. Which means Lenovo tweaked the GTX 1050 Ti with an additional 203 MHz/ 228 MHz, base/boost clock- a maximum of 16.38% increase in clock speed.

There are two graphics accelerators- the onboard Intel 630 on the CPU and the discrete option GTX 1050 Ti 4G. It will be best if the driver settings are set to use the GTX 1050 Ti as a graphics solution option over automatic as it would toggle between the options depending on the power left on the notebook.

Apart from that, There are two internal storage drives- an M.2 22110 drive and a 2.5” 7mm mechanical HDD. The NVMe M.2 drive will greatly provide a boost in performance, which explains Lenovo’s concentration on load and system boot speed.

Packaging and Specification

The Lenovo Y520 comes in a box (obviously) with the accessory and the notebook nicely packed. This review unit only has the power adapter as an accessory. The notebook is protected by a soft foam with the accessory box over it. The notebook is covered with a soft cloth and another piece of cloth between the screen and the keyboard.
