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.

Full memory encryption is supported

Multi-layered security features

In addition, AMD works with hardware and software partners to provide users with multi-layered security features, allowing the Ryzen™ PRO 4000 series platform to better protect user data.

Manageable and business stability

The Ryzen™ PRO 4000 Series supports a flexible and integrated cloud management solution through Microsoft Endpoint Manager, as well as a complete manageability feature set for easier deployment and management. Support for both modern and traditional management makes the Ryzen™ PRO 4000 series more flexible.


Business stability

At the same time, the Ryzen™ PRO 4000 series can also provide up to 18 months of system image stability, and the processor supply period for enterprises up to 24 months to ensure long-term stable system operation.

02 Ryzen 7 PRO 4750U powerful performance

Returning to the product, the ThinkPad L14 is equipped with the Ryzen 7 PRO 4750U, which is also the strongest model of the current Ryzen PRO 4000 series. It is based on TSMC’s 7nm process technology, with 8 cores and 16 threads of horror specifications, a base frequency of 1.7GHz, a maximum acceleration frequency of up to 4.1GHz, a three-level cache of 8MB, and a TDP of 15W. The built-in graphics card model is AMD Radeon Graphics, with 7 GPU cores and a graphics card frequency of 1600MHz.

Ryzen 7 PRO 4750U specifications

The Ryzen 7 PRO 4750U has terrifying specifications, and the measured results are also very powerful. Cinebench R15 multi-core score of 1455cb, single-core score of 184cb; The Cinebench R20 scored 3184pts for multi-core and 474pts for single-core. This performance is already comparable to the H-series processors launched by competitors for gamebooks, and the multi-core performance has even exceeded, which is a high-end level in thin and light notebooks, and the powerful performance can be seen.

Cinebench R20

Of course, the performance of the Ryzen 7 PRO 4750U is not only excellent in the processor itself, but also has a certain relationship with the performance release of the ThinkPad L14. The ThinkPad L14 has built-in intelligent cooling that offers three modes: quiet, balanced, and performance. To its credit, it binds the three modes to Windows 10’s battery usage mode, and the slider to adjust the battery usage mode can be switched between the three modes, and the design is straightforward and simple to operate, which is worth learning from other brands. Since the aircraft offers a performance mode, all tests are performed in performance mode except for endurance.

In the CPU single-bake test, using the AIDA64 system stability test program, only check the Stress FPU, and after 30 minutes, the all-core frequency of the Ryzen 7 PRO 4750U is stable at about 2.67GHz, the power consumption is stable at 22W, and the core temperature is only 74°. From the results, the heat dissipation effect of the ThinkPad L14 is quite good, and it can also be seen that the performance ceiling of the Ryzen 7 PRO 4750U is very high.

In addition, I also used PCMark 10 to test the performance of the whole machine, and finally got a total score of 3583 points, including 8445 for common basic functions, 6848 for productivity, 4518 for digital content creation, and 1706 for games. In terms of scores, the ThinkPad L14 is very suitable for office use and can cope with some creative work, which is mainly due to the Ryzen 7 PRO 4750U.

I also tested AMD Radeon Graphics, an integrated graphics card, using 3DMark software. Time Spy mode has a total score of 792, a graphics card score of 690, and a CPU score of 4975; In Fire Strike mode, the total score is 2048, the graphics score is 2314, and the CPU score is 14563. It can be seen from the score that although it is an integrated graphics card, AMD Radeon Graphics already has a level comparable to an entry-level exclusive graphics. In addition, the CPU score is high-end, which also shows the power of the Ryzen 7 PRO 4750U.

Powerful performance, but no loss of battery life. The ThinkPad L14 has a built-in 45Wh battery, and with a screen brightness of 150cb/m2 (75% brightness), quiet mode, and Wi-Fi connection, PCMARK 10 Modern Office Mode score of 8 hours and 34 minutes, which can meet the needs of 8 hours of office in a day. The Ryzen™ 7 PRO 4750U delivers outstanding performance, while the leading 7nm process technology and the energy-efficient design of the Zen 2 architecture also ensure battery life.

Battery life results

Finally, there is the hard drive test. The ThinkPad L14 uses a 512GB PCIe 3.0×4 SSD, the Western Digital SN730. When the number of queues = 8 and the number of threads = 1, the continuous reading is 2885MB/s and the continuous writing is 2718MB/s. When the number of queues = 1 and the number of threads = 1, 4K random reads are 47.36 MB/s and 4K random writes are 128.66 MB/s. The hard disk performance is very good, belonging to the current flagship level of PCIe 3.0 SSD.
