Gordon Mah Ung , editor of IT news site PCWorld , has published the performance of the Ryzen 4000 series of APUs for mobile devices, which was announced by AMD at CES 2020, the world's largest technology trade fair.

The Ryzen 4000 series adopts the Zen 2 architecture of the 7 nm process, and the Ryzen 4000 series high-end model `` Ryzen 9 4900HS '' has an 8-core, 16-thread CPU with a base clock of 3 GHz and a boost clock of 4.3 GHz And it is an APU with 8 Radeon Vega cores as GPU. The test used is a ASUS notebook PC ' ROG Zephyrus G14 ', and a dGPU equipped with NVIDIA ' GeForce RTX 2060 Max-Q '. It is difficult to completely match the conditions other than the CPU like a desktop PC like a desktop PC, so it is necessary to consider the size and weight of the notebook PC to be compared with the score.

First of all , when testing multi-thread performance with ' Cinebench R15', Ryzen 9 4900HS has the highest score among mobile CPUs. It is necessary to consider that it can not demonstrate all the performance because it is mounted on the notebook PC, but it is also thin in the score for `` Core i9 9900K '' which is a CPU for desktop, and AMD's previous generation desktop CPU `` Ryzen 7 2700 '.

When comparing the multi-thread performance again with `` Cinebench R20 '' corresponding to new elements such as Cinema 4D and AVX instruction set, as well as the test with R15, the score that greatly separates other mobile CPUs is also recorded. You.

Comparing the single-thread performance of the R15, the size of the installed notebook PC is large, which is advantageous in terms of cooling, and lags behind the high-clock Intel CPU.

In the R20's single-thread test, I beat the top score. You can see that the latest software can bring out the performance of Ryzen 9 4900HS.

Here's the result of comparing the time it took to encode a 1080p video with a capacity of 30GB with HandBrake to compare the video encoding performance. Despite the relatively small size of the notebook PC itself, which is disadvantageous in terms of cooling, it is performing well in the second place among mobile CPUs.

Next,

let 's look at the CPU performance in the game from the Time Spy CPU score of the benchmark software ' 3DMark '. Although it does not reach the score of the top two models with large laptops, it is significantly different from the `` Core i9 9880H '' mounted on the MSI ` ` GE65 Raider '' which is heavier than the ROG Zephyrus G14 equipped with Ryzen 9 4900HS .

Finally, play the 4K video and check the battery life. The battery duration is an item that is easily affected by the size of the GPU and battery mounted on the notebook PC in addition to the CPU, so it is difficult to make a simple comparison, but the ROG Zephyrus G14 equipped with Ryzen 9 4900HS has a good battery life It can be said that.

The Ryzen 4000 series can only use 3rd generation PCIe x8 lanes, so devices that require PCIe x16 lanes cannot be used. However, Gordon said that this is not a problem, since PCIe x16 lane performance is rarely needed in consumer applications.

Gordon, who completed the test, was surprised by Ryzen 9 4900HS which performed excellently under severe heat and power constraints, saying, `` In the 50-year history of AMD, Intel in the field of mobile CPU I've never beaten, but the Ryzen 4000 series will change that. '
