After AMD's CPU architecture turned to ZEN, the legendary architect JimKiller was born, Ruilong and RyzenThreadripper realized the good performance and high performance of the desktop respectively. Now Zen architecture will also be introduced into the eighth generation APU product line of notebook computers and integrated into the new generation GPU architecture Vega. At present, AMD has released two new combinations of notebook computer APU products for the first time, namely Ryzen52500U and Ryzen72700U, both of which use 4-core and 8-thread CPU with VEGAGPU, and adopt 14nm process, which is scheduled to be 15WTDP, which can be flexibly adjusted between 9W and 25W according to product performance requirements, and emphasizes that CPU performance is better than the seventh generation notebook APU.

At present, Lenovo's aPad720S, Acer's Swift3 and HPEnvyX360 will all use the eighth generation notebook version of APU, but the time to market has not yet been decided, and whether there is a listing plan is unknown.

Basically, Ryzen52500U is very close to Ryzen72700U, both of which are based on the 4-core CCX module with Vega. Both of them only support DDR4 memory and do not support DDR3L with lower power consumption. The main difference is the amount of CU in the core clock and GPU. The base clock of Ryzen52500U is set to 2.0GHz, Boost reaches 3.6GHz and 8 VEGACU, and the GPU clock is set to 65438+. As for Ryzen72700U, the base clock is set to 2.2GHz, the Boost clock reaches 3.8GHz, and the GPU clock is set to 10 VegaCU, 300MHz.

Although the desktop product line is basically continued in the infrastructure, AMD has launched a new dynamic clock adjustment technology for notebook computer environment, and adopted PrecisionBoost2 as the CPU clock adjustment technology. Compared with the previous PrecisionBoost for desktop products, PrecisionBoost2 can be fine-tuned in 25MHz according to more accurate temperature and workload changes. In addition, XFR technology has developed into MobileXFR, but unlike desktop XFR, it can be used directly. The MobileXFR adopted by APU can only be activated if it meets the heat dissipation design formulated by AMD, and the maximum upper limit is the Boost clock increase 100MHz.
