2017 has been a pretty great year for AMD’s new Ryzen processers. AMD is able to catch up to what Intel is currently offering in the CPU market, with the Ryzen 3/5/7 and the Ryzen Threadripper processors. There were multiple benchmark leaks about AMD’s new Ryzen-based mobile APU last month. Now, AMD finally introduced the APU with 2 models, the Ryzen 7 2700U and Ryzen 5 2500U.

AMD claims that the new APUs are the highest performance processors ever for ultra-thin notebooks. The APUs are combining both the same micro-architectures of Ryzen CPUs (Zen) and the Vega Graphics into a tiny mobile processor.
There will be two models of Ryzen mobile APUs for now. Both of them have a 4-core, 8-thread CPU inside, but is clocked slightly differently. The Ryzen 7 2700U’s CPU is clocked at 2.2 GHz and can boost up to 3.8 GHz. It also has 2 more Vega compute units on the graphics side. The lower end Ryzen 5 2500U has a base clock of 2.0 GHz and a boost clock of 3.6 GHz. It has a total of 8 Vega compute units, instead of 10.
According to AMD, the APUs have 58% lower power consumption than the 7th generation APUs, at about 15W. This is on par with Intel’s latest 8th generation mobile CPU (Core i5-8350U and i7-8650U), but the main difference is the APU has a much powerful Vega GPU inside than Intel’s internal graphics. Notebook manufacturer will need to add an extra GPU in order to match the performance, which would increase the total power consumption to more than 40W, harming the battery life.
AMD had done a 3DMark Fire Strike benchmark and compared with its Intel counterparts. This benchmark is to test out the GPU performance of the processors. Both the Ryzen 7 2700U and Ryzen 5 2500U APUs scored over 2000 points, while all Intel’s CPUs got around 1000 points.
The Ryzen 5 2500U’s score is 118% better than the Core i5-7200U, 134% better than the Core i7-8550U, and 120% better than the Core i7-7200U. The Ryzen 7 2700U has a even higher score, about 23.7% higher than its sibiling (Ryzen 5 2500U). The Vega graphics inside the new Ryzen mobile APUs seem to be very promising, averaging at least two times greater GPU performance than Intel’s internal graphics.
A Cinebench R15 benchmark is also shown on AMD’s launch video for the Ryzen 5 2500U APU. It is to test how the CPU performs in rendering high-quality photo. The Core i5-7200U scored 330 cb, while the Ryzen 5 2500U scored 524 cb, about 58.7% higher.
However, AMD did not show the performance number of the Ryzen 7 2700U APU.
AMD Ryzen mobile processors will be on shelf within the next few weeks in ultra-thin notebooks, from OEM companies like HP, Acer and Lenovo. More designs will be available in next year’s CES.
