AMD Ryzen processors want to power your next skinny laptop

AMD Ryzen CPU

Nevertheless, it was only last night that AMD has finally revealed the full specifications of its Ryzen Mobile chips. The difference is Intel's processors use a "refreshed" version of the seventh-generation Kaby Lake architecture and a rebranded version of the graphics processor that gains most of its improvements through the addition of a couple of cores and some tweaks.

Part of how AMD is accomplishing this is through things like the company's revised Precision Boost 2 technology, which more intelligently manages how much the CPU can boost as workload increases on a more granular level. Targeting ultrathin and 2-in-1 devices, the AMD Ryzen 7 2700U and Ryzen 5 2500U combine Zen with Vega graphics into an SoC for greatly improved performance.

Implementing only a single CCX is an important step forward for reducing power consumption enough to lower temperatures and fit Ryzen into slim devices. It also works in hand with SenseMI's Extended Frequency Range (XFR) feature although users can only utilize this feature if their laptops are included with high-performance cooling solutions. They both also support dual-channel DDR4 memory, up to 2400MHz. This potentially allows for better power savings and, depending upon the applications you run, better performance. The Ryzen 5 2500U is clocked at a base speed of 2.0GHz (which can be boosted to 3.6GHz), with the Ryzen 7 2700U coming in at a base speed of 2.2GHz (which can be boosted to 3.8GHz). The Vega GPU cores chosen for both APUs are capable of providing playable performance for many popular titles.


The AMD Ryzen 7 2700U is able to deliver 59 FPS in League of Legends at medium settings at 1080p. Lowering the resolution will be required for more intensive games, but considering the size and weight of HP's X360 thin and laptop as well as battery life, this is a reasonable compromise. Another area where the latest U-series processor could have the edge over Raven Ridge is power efficiency.

At least three different laptops with Ryzen Mobile will be available by the end of November.

Apart from HP, Ryzen mobile powered systems will be launched by other leading PC makers such as Lenovo and Acer. Others, including Dell, will have debut mobile Ryzen laptops early next year.
