The specifications of the Ryzen PRO 4000 series announced by AMD are as follows. Lineup is 8 cores 16 threads, base clock 1.7 GHz / maximum 4.1 GHz 'Ryzen 7 Pro 4750U', 6 cores 12 threads base clock 2.1 GHz / maximum 4 GHz 'Ryzen 5 Pro 4650U', 4 cores 8 threads base clock 2.5GHz / 3.7GHz up to three 'Ryzen 3 Pro 4450U'. The 'U' in the model name means that the TDP, which is a measure of power consumption, is 15 W and is for ultra-thin notebook PCs.

The greatest feature of the Ryzen PRO 4000 series is high security. In addition to adopting the '

Secured-core ' technology advocated by Microsoft for the chip, it also supports 'AMD Memory Guard' that completely encrypts the physical memory.

Also, the specifications have been significantly enhanced. The bar graph below is a comparison of the results of various benchmarks performed on the AMD Ryzen 7 PRO 4750U and the AMD Ryzen 7 4700U of the ' Ryzen Mobile 4000 ' series announced in January 2020. From the top, the benchmarks we conducted compare the results of 3D modeling with Cinebench and Blender , file compression with 7-Zip , video encoding with HandBrake, and video editing speed with Adobe Premiere Pro. You can see that the Ryzen PRO 4000 series excels in all five items.

It also shows superiority over its rival Intel Core series. Below is a comparison of the AMD Ryzen 5 PRO 4650U and Intel Core i5-10210U, the bar graphs represent single-threaded, multi-threaded and graphic performance from the top. In particular, the graphics performance of the AMD Ryzen 5 PRO 4650U is more than double that of the Intel Core i5-10210U, and you can see at a glance that it has a large amount of water.

In addition, we have succeeded in greatly reducing power consumption by 'Idle detection' that powers down the component while not in use, 'Activity detection' that boosts the component quickly when necessary, etc. It also contributes to a significant increase in battery life.

On February 24, Lenovo announced T14, T14s, L14, L15 and small model X13 as ThinkPad 2020 model , but these will be equipped with 'Ryzen PRO 4000' series. Both models are scheduled to be released in June 2020, but the release schedule in Japan is undecided.

ThinkPad T14 is priced from $ 849 (about 90,000 yen), T14s is $ 1029 (about 109,000 yen), L14 and L15 are both $ 649 ( From about 69,000 yen), X13 is said to be 849 dollars.
