AMD makes new Ryzen mobile CPUs with 15W and 35W TDP at 12nm

AMD announced a new range of laptop processors at CES. Just like with the desktop, the chip designer has switched to the 12nm process and has released two processors with a tdp of 35W in addition to the usual 15W processors.

AMD has mainly intended the new processors with a TDP of 35W for gaming laptops. Until this introduction, AMD only built Ryzen processors with a TDP of 15W, which prevented it from competing with Intel’s processors with six cores and a TDP of 45W. The Ryzen 7 3750H has the same properties on paper as the new 3700U processor, but due to the higher TDP configuration, it can continue to run at higher clock speeds for longer, making the CPU faster than the 3700U in practice. The same goes for the Ryzen 5 3550H and 3500U.

Thanks to the switch to the 12nm process, the clock frequencies were also able to increase slightly, while the processors have remained within the same TDP. According to AMD, the performance difference between the previous and the new generation Ryzen mobile processors is about eight percent. In addition, the new processors support modern standby, allowing a laptop to wake up faster from standby, possibly using a voice command.

According to AMD, the new CPUs also improve in terms of battery life. With a Ryzen 7 3700U on its own reference motherboard, the manufacturer achieves a battery life of 12.3 hours during typical use, with a brightness of 150cd/m² on a full-HD screen of 14″ and a battery of 50Wh. While playing video It achieves a battery life of ten hours, which is significantly better than the Lenovo IdeaPad 530S with Ryzen 2700U CPU, which compares AMD to 8.1 and 6.9 hours, considering the use of other components, including the smaller 45Wh battery in that system, however, that comparison is not entirely fair.

Asus has already chosen to release a laptop with the new Ryzen 5-3550U processor, in the TUF series, which is positioned by Asus among the ROG laptops. The new Ryzen 5 CPU is combined with a Radeon RX560X GPU and the screen is optionally equipped with FreeSync, with a maximum refresh rate of 120Hz.
