Test the Lenovo ThinkBook 13s – sleek and well-made Ultrabook with a powerful AMD Ryzen 7 5800U processor and Windows 11

Lenovo offers a very extensive catalog of laptops for home and business – we can choose cheaper, but generally less well-made models from the Lenovo IdeaPad family, or better and often with additional features, but also Lenovo models Much more expensive ThinkPads. Between the two series, however, can be found a third, which seems to combine a slightly lower price known from IdeaPads with better build quality known from much of the more expensive ThinkPads. I’m talking about the Lenovo ThinkBook family, which should meet the expectations of a universal laptop for everyday use, including for work. Today we will focus on such a model – Lenovo ThinkBook 13s, which seems to be one of the most interesting ultrabooks for less than 5000 PLN.

Lenovo ThinkBook 13s is a stylish and universal laptop that combines fairly high performance and mobility. The hardware is based on an AMD Ryzen 7 5800U processor with 8 cores and 16 threads. Contrary to appearances, there weren’t too many laptops with low-voltage AMD Cezanne processors in the last year, so I was even more curious as to how the Lenovo ThinkBook 13s would fare in use daily. It is also a piece of equipment that will work in the preparation of documents or frequent Internet surfing. This is due to the high resolution screen and the 16:10 aspect ratio, which are slowly returning to favor in the case of laptops. Although the equipment, looking at the specifications, looks like an expensive laptop, now we can buy it for 4699 PLN – many ultrabooks with lower performance can cost much more. The Lenovo ThinkBook 13s is not bad in this regard, especially since a powerful processor with impressive energy efficiency is not among its strengths.

The Lenovo ThinkBook 13s is a slim and stylish laptop, featuring an 8-core AMD Ryzen 7 5800U processor and a 13.3-inch IPS display in a 16:10 aspect ratio. Everything works under the control of Windows 11 Pro.

The Lenovo ThinkBook 13s is equipped with an AMD Cezanne-U APU family processor. The AMD Ryzen 5000U series (Ryzen 3 5400U, Ryzen 5 5600U, and Ryzen 7 5800U) utilizes the simplified Zen 3 architecture which offers notable increases in single-threaded performance and further increases in multi-threaded performance. The new Cezanne chips offer a maximum of 8 cores and 16 threads, but at the same time compared to APU Renoir, we gain twice as much L3 cache. The unit tested is an AMD Ryzen 7 5800U with a TDP of 15W. The CPU base clock is 1.9 GHz with the ability to Turbo mode up to a maximum of 4.4 GHz. AMD Cezanne processors also feature a 2-channel DDR4 3200 MHz and LPDDR4x 4266 MHz memory controller (this is the type of memory used in Lenovo ThinkBook 13s). The biggest problem with the AMD Cezanne APU is the small number of PCIe lanes for a discrete graphics card – we only have 8 PCIe 3.0 lanes available to us, although in the case of thin laptops without dGPUs this will not be very noticeable. PCIe 4.0 was only introduced with the debut of the latest generation of Rembrandt APUs, i.e. the Ryzen 6000 series systems.

The integrated graphics system has also been improved, still based on the Vega architecture (the transition to iGPU RDNA 2 only took place in the Ryzen 6000 series of the Rembrandt APU family), but produced in the TSMC 7nm process. In terms of improvements, the new iGPUs are closer to the Radeon VII than to the previous versions of Vega. Unlike the first two generations of APUs, the Cezanne family will receive an iGPU with up to 8 CUs. The reduction in space aims to improve energy efficiency, but at the same time to increase the efficiency of each CU block compared to Picasso – in this case, the manufacturer claims up to 59% higher efficiency. To increase data transfer, the Data Fabric interface has been enlarged twice. Also, due to the transition to a lower technology process, the core clock has dropped to 25% – in the case of the Vega 8 iGPU in the Ryzen 7 5800U, the graphics core clock is maxed out at 2000 MHz .
