Lenovo Yoga Book 9i test – An innovative, hybrid ultrabook with two excellent OLED screens


Lenovo Yoga Book 9i test - An innovative, hybrid ultrabook with two excellent OLED screensA few years ago, Lenovo introduced an interesting concept of an ultrabook with two screens. We are talking about the Lenovo Yoga Book, the first presentation of which took place in 2016. This was the company’s first idea for such an unusual hybrid, so it was also limited on many levels. Mainly due to weak components – 4-core Intel Atom, 4 GB RAM or 64 GB eMMC drive with the possibility of inserting a microSD card. Plus the screens were relatively small, and in addition, the main matrix was surrounded by terribly wide frames. However, the company did not abandon that concept, resulting in the Lenovo Yoga Book 9i model. Still not perfect, but better in every way than what we saw in 2016.

Lenovo Yoga Book 9i also has two screens, but this time they are OLED panels with a diagonal of 13.3″ and a resolution of 2880 x 1800 pixels each. The frames around the screens are much slimmer, which also affects the overall appearance of the device. Two matrices allow for using the hybrid in various ways. It can be a classic laptop, a tablet, a laptop with a “hanging” second screen above the main one, or even something that resembles an electronic book. The last two ways of using the Lenovo Yoga Book 9i are possible thanks to a special cover in which by default, the physical keyboard is hidden (to connect to the laptop via Bluetooth). We can fold the cover as in the photo below, and then place the case in one or the other position in the place with the magnetic hinge to obtain a satisfactory end result. I must admit, that the Lenovo Yoga Book 9i is a fascinating device, and its testing was largely different than for typical laptops. When it comes to performance, inside we will find an Intel Core i7-1355U processor, 16 GB RAM LPDDR5 6400 MHz and 1 TB SSD PCIe 4.0 x4 NVMe. In this respect, we have a huge gap compared to Yogi Book from 2016.

Lenovo Yoga Book 9i is a very distinctive, hybrid ultrabook that uses, among others, from two OLED screens. The unusual housing, combined with the included cover, allows you to work in several, completely different operating modes.

The Lenovo Yoga Book 9i hybrid uses Intel Raptor Lake-U processors, which are the third generation (after Intel Lakefield and Alder Lake) with a hybrid x86 architecture. 13th generation processors use two types of cores – Performance (Raptor Cove architecture), where the core has been slightly improved compared to Golden Cove, including: cache memory. Performance cores are additionally supported by more energy-efficient Efficient cores – they offer IPC at the level of an x86 core from the 10th generation Comet Lake, while consuming noticeably less energy compared to large Performance cores. The tested model has a 10-core and 12-thread Intel Core i7-1355U processor with integrated Intel Iris Xe Graphics with 96 EU. The Processor Base Power factor in the Lenovo Yoga Book 9i model is 15 W, while Max Turbo Power is 55 W.

The laptop is also equipped with an integrated Intel Iris Xe Graphics (Intel Gen.12) graphics chip, which is based on the Xe architecture. Intel Iris Xe Graphics is a representative of the weakest Xe-LP (Low Power) line, which has a maximum of 96 EU units (execution units) built-in. The tested Intel Core i7-1355U processor has the highest variant with 96 EU. This translates into a total of 768 stream processors. The integrated Iris Xe Graphics system still uses RAM – the Lenovo Yoga Book 9i uses LPDDR5 6400 MHz chips with a capacity of 16 GB. The Intel Xe-LP architecture also features lower power consumption and the use of a technological process known as Intel 7 (10 nm). Intel Iris . Intel Iris Xe Graphics is currently a lower shelf among Intel’s iGPU systems – in the coming months it will be successively replaced by Intel ARC Graphics, which is part of the modular Intel Meteor Lake processors. I personally hope that the Lenovo Yoga Book concept will soon be expanded to include these systems.
