Lenovo Legion Y720 Laptop Review: High Performance, Affordable Mobile Gaming

We tested the Legion Y720 as it shipped from Lenovo to ensure we get the same out-of-box experience as our readers that may purchase it. Many variables can affect performance so our comparisons should serve as a reference point. Our benchmarking kicks off with storage, CPU and GPU tests to get an idea how the Legion Y720 performs in day-to-day tasks for these high level subsystems.

ATTO Disk Benchmark Peak Sequential Storage Throughput

The ATTO disk benchmark gives us a quick look at how snappy the Lenovo Legion Y720 should feel for basic tasks such as Windows startup and app loading. Lenovo installs its own in-house-branded LENSN20256GMSP34 SSD in the Legion Y720. We don’t know much about this SSD except its NVMe and PCI Express 3.0 x4.  Branding-aside, the Lenovo Legion Y720 has a fast SSD that sees read speeds excess of 2.5GB/s and writes of over 1.1GB/s. It has zero trouble keeping up with your everyday gaming and desktop usage.

SunSpider JavaScript Benchmark JavaScript Processing Performance

SunSpider tests JavaScript performance to provide a good idea of what to expect with web browsing. We used the default Edge browser in Windows 10 to run the benchmark.


Here the Legion Y720 performs as we’d expect from the Intel Core i7-7700HQ – falling within a margin of error of its competition.

Cinebench R11.5 3D Rendering On The CPU And GPU

Cinebench tests the CPU and GPU independently and provides a glimpse of raw performance. The test is based on Maxon’s Cinema 4D modeling software that’s used in move productions.


There are no surprises here either, the Legion Y720 performs as you’d expect from a Core i7-7700HQ and a GeForce GTX 1060.
