AMD has finally announced its Ryzen mobile processors, previously codenamed “Raven Ridge” APUs. The processors combine the company’s award-winning “Zen” x86 cores and Radeon Vega graphics on a single chip to provide unprecedented ultrathin notebook performance. In fact, AMD claims the flagship Ryzen 7 2700U is so powerful that it can outperform Intel’s 91W Core i5-7600K Kaby Lake desktop CPU.
AMD Ryzen 7 2700U and Ryzen 5 2500U Specifications
The Ryzen 7 2700U has four cores with simultaneous multi-threading (SMT) for a total of eight cores. There are 10 compute units based on the Vega graphics architecture, which will clock up to 1,300MHz. The chip runs at a base clock speed of 2.2GHz and boost speed of 3.8GHz.
The Ryzen 5 2500U is also a four-core, eight-thread chip, but differs from the Ryzen 7 2700U in the number of compute units and the CPU and GPU clock speeds. The Ryzen 5 comes with 8 compute units instead of 10, and the cores will clock up to 1,100MHz. The CPU clock speeds are also slightly lower than its elder sibling: 2GHz base and 3.6GHz boost clock.
Both Ryzen mobile processors feature a configurable 15W TDP. The chips also introduced for the first time:
- New Precision Boost 2.0 technology, which accelerates processor performance in workloads using one or many CPU cores, and
- Mobile Extended Frequency Range (mXFR) raises sustained performance in notebooks with optimum cooling solution and certified for “Ultimate XFR Performance.”
Ryzen 7 2700U vs Core i7 Kaby Lake & 8th Gen Kaby Lake Refresh benchmarks
In terms of performance, the new “Zen”-based APU far exceeded its target goals. It delivers 200% faster CPU performance and 128% faster GPU performance over previous 7th-generation Bristol Ridge APUs, while using 58% less power.
From the performance numbers showcased by AMD, it looks like the new Ryzen/Vega U-series processors could give Intel a run for its money. In Cinebench R15 CPU test, the Ryzen 7 2700U beats Intel’s Core i5-7600K desktop chip by a significant margin, which is incredibly impressive.
When compared against the Core i7-8550U Kaby Lake Refresh, both Ryzen 7 and Ryzen 5 mobile chips have it beat in POVRay 3.7, PCMark 10 (Extended) and TrueCrypt 7.1a benchmarks. The newest Intel chip could manage to take the lead only in PassMark 9, and that is not by much.
The AMD Ryzen mobile processors are initially intended for a small range of ultrathin notebooks and 2-in-1 devices from top manufacturers including Acer, HP, and Lenovo that will be available within weeks. A wider range of Ryzen-powered laptops will hit the shelves in early 2018 that will include further platform updates from Dell, Asus and other OEMs.
