Intel launched its latest eighth-generation U series processor- the Intel Core i7-8565U based on Whiskey Lake. This chip boasts powerful performance, low power consumption, and excellent heat dissipation. As Intel’s important strategic partner, Lenovo published several laptops with processors built on the Whiskey Lake framework, such as Lenovo Air 13IWL and Yoga C930. But the Air 13IWL is powered by the Intel i5-8265U processor. Recently, Lenovo’s new product – the Lenovo Yoga S730 powered by i7-8265U will be released in the market soon.

Remove nine screws, and the back cover can be taken out. From the picture, the Yoga S730 has a neat internal layout. We can only see the antenna of the wireless module. The cable of its other components is connected to the motherboard.
The battery almost occupies half of its internal space. It can work 12 hours, and its capacity is 42Wh.
This is the cover back which is covered by a layer of copper foil. This foil is good for the laptop’s heat dissipation.
The laptop is powered by Intel Core i7-8565U which is Intel’s lastest eighth-generation low-voltage Whiskey Lake processor. This chip’s frequency reaches up to 4.6Ghz.
The component on the left is LPDDR3 memory made by Micron. There are eight chip strips, four on the front and four on the back. All of the eight strips constitute to the dual passage.
The Samsung PM981 1TB M.2 SSD belongs to the high-end type for OEM clients. This SSD uses Samsung’s new Phonenix main controller, and its cache upgrades to 1GB LPDDR4. According to our test, the SSD’s sequential read speed is 3200MB/s, and its sequential write speed is 1900MB/s.
This is the Intel 9260 AC wireless module which adopts dual passage and dual antenna design. Its transfer speed reaches up to 1.73Gbp. With a built-in Bluetooth 5.0, this module can be connected to eight external devices at the same time.
Its heat dissipation module consists of a fan and dual pipes.
Appearance
The Lenovo S730 uses an aviation aluminum alloy and adopts the CNC process. There is only a logo on the top cover.

We use the Spyder5 Elite to test this IPS display. According to the test results, this display’s sRGB color gamut reaches up to 100% and its AdobeRGB color gamut is 75%. In terms of its color gamut performance, this display owns a wide gamut.
Ports
The right of the laptop provides two USB Type-C ports which support Thunderbolt 3.0 technology.
On the left of the laptop include a USB Type-C port and the 3.5mm audio/mic. The Type-C port support charging.
CPU
On CPU-Z, we can see this CPU’s single-core score is 495 and its multi-core score is 2008.
On the CineBench R15, this processor’s single-core score is 175cb, and its multi-core score is 621cb.
SSD
This laptop comes with the Samsung PM981 1TB SSD. Samsung released this high-end SSD in the OEM market.
On the AS SSD Benchmark, this Samsung PM981 1TB SSD’s score is 3734. Its sequential write speed is 2304MB/s. Sequential read speed is 2636MB/s, 4K random read speed is 46MB/s, and its 4K random write speed is 88MB/s.
On the CrystalDiskMark, the SSD’s sequential read speed is 3219MB/s, and sequential write speed is 1734MB/s. In general, this SSD has excellent performance.
Battery Life
The Yoga S730 sports a 42Wh battery. According to the Lenovo official party, this battery’s life is up to 12 hours. We use the PCMark8.0 to measure its battery life. During the test, we close all the applications and adjust its brightness to 60%. Under the Work2.0 of PCMark8.0, its battery life is 4 hours and 41 seconds. This laptop is supposed to work about eight hours for daily use.
Summary
The Yoga S730 is a good laptop. First of all, the Intel Core i7-8565U this laptop is powered by is a powerful processor. It weighs 1.1kg and its thickness is only 11.9mm. This is one of the most lightweight laptops in the laptop market.
I have purchased this product and it is quite fast and good, except for the fact that there are NO USB ports. Honestly, it’s quite stupid.
Can I expand the SSD and/or RAM? I got the i5 model with 512GB SSD and 8GB of RAM.
Yes, you can upgrade the M.2 SSD, but the RAM is soldered to the motherboard, so it can’t be upgraded.
