Lenovo Legion Y740 Gaming Laptop Deep Dive Review With Benchmarks

The only changes made to the Lenovo Legion Y740 prior to testing were to fully update the OS and any drivers that were avalable. Other than that, except where noted, we kept all other settings unchanged from the factory. First up, we'll take a look at the storage devices inside of the Lenovo Y740. Our test unit came with a 256GB Samsung M.2 SSD for the OS installation and a 1TB SATA HDD for additional, bulk storage.

ATTO Disk Benchmark
Peak Sequential Read And Write Storage Throughput
ATTO is a relatively simple test that checks read/write performance of storage devices with various block sizes.

The Samsung SSD in the machine peaked with a read speed just shy of 2GB/s. Write speeds peaked at 1.3GB/s+ right around the 32K transfer size, and remained consistent the rest of the way through the test run. Overall, not the fastest SSD we have seen in a gaming notebook, but respectable speeds to be sure.

Cinebench R15
3D Rendering On The CPU And GPU

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

The Core i7-8750H in the Lenovo Y740 put up the best score we've seen from a notebook in this class to date. GPU performance was just slightly behind the 1070 Max-Q, but Cinebench's GPU benchmark is also CPU dependent and behaves differently depending on the drivers that are installed, so they don't necessarily jibe with actual games or more taxing graphics benchmarks that are fully GPU bound.
