01 Advantages of the AMD Ryzen™ PRO 4000 series

Friends who contact the PC know that AMD’s Ryzen series processors are very powerful, the architecture process is both upgraded, and the performance leap, and this fine tradition is also reflected in the Ryzen PRO 4000 series.

The three advantages of the AMD Ryzen™ PRO 4000 series

The advantages of the Ryzen™ PRO 4000 series can be simply summarized in the following three points:

Many cores support Hyper-Threading Technology

The highest model of the Ryzen PRO 4000 series, the Ryzen 7 PRO 4750U, has 8 cores and 16 threads, which is quite a luxurious specification in a thin and light notebook. And the Ryzen PRO 4000 series has a better core count in each gear than the competition, with 2 more physical cores. The more cores, the stronger the performance, coupled with the huge improvement of the Zen 2 architecture in terms of single cores, the performance advantages of the Ryzen PRO 4000 series are obvious to the naked eye.

Hyper-Threading Technology is supported across the series

More than just physical cores, the entire Ryzen™ PRO 4000 series supports Hyper-Threading Technology. If you think of yourself as a physical core, hyperthreading is equivalent to two hands. Supports Hyper-Threading Technology, which is equivalent to working with two hands at the same time. Without supporting Hyper-Threading Technology, it is equivalent to tying one hand and operating with only the other. Working with two hands at the same time is certainly more efficient and handles more work at the same time than with one hand.

This is precisely the advantage of Hyper-Threading Technology. Of course, Hyper-Threading Technology does not double the performance, but the theoretical improvement is about 20%, which is equivalent to a 20% increase in efficiency. The greater advantage of hyper-threading technology is that in multitasking, the more threads, the more tasks can be processed at the same time, which is quite important for the current business scenario, after all, the work needs to run multiple software at the same time, and switch at any time. Support Hyper-Threading Technology, which can better cope with multi-task operations and be more efficient.

The Ryzen™ PRO 4000 series delivers up to 132% more multi-core performance and 29% better single-core performance than the previous generation.

Energy-efficient design

In addition, the Ryzen™ PRO 4000 series uses the leading 7nm process technology, while the Zen 2 core is designed to be energy-efficient, doubling the performance but consuming better power to provide better battery life.

Modern multi-layered security design

Data security is critical to businesses, and the Ryzen™ PRO 4000 Series is designed with a leading-edge architecture to deliver more modern security features. One of them is AMD Memory Guard technology, which supports full memory encryption to avoid data leakage even if it is attacked. This feature is only supported by AMD PRO processors.
