The first Ryzen 7 5800H! ASUS Tianxuan 2 Gaming Book Review: Genius AMD Engineer

Ryzen 5000 mobile APU designed for notebooks is coming

If AMD has any regrets before today, then there are so many top Core gaming notebooks, but there has never been a top Ryzen gaming notebook!

Why is there such a situation? Everyone has different opinions, and there are also various unreliable rumors and speculations. Of course, the main reason is that the Ryzen 4000H series processor products themselves, strictly speaking, on the notebook platform, is not a top-level gaming processor.

But everything is in the past because AMD has created a new Ryzen 5000H series of mobile processors that will completely change the world!

From the above picture, the architecture of the Ryzen 5000 series mobile processor code-named "CEZANNE" is almost the same as that of the Ryzen 4000 series mobile processor. The biggest or even the only difference is that the CPU core is designed from the original dual CCX. Changed to a single CCX design, and at the same time increased the L3 cache capacity from 8MB to 16MB, and it is integrated and can be shared by all cores.

The core display is an 8CU Vega GPU with a maximum of 512 stream processors. The PCIe version is still 3.0, there are 16 in total, 8 are connected independently, and the other 8 are allocated by the notebook manufacturer. These are exactly the same as Zen2 mobile processors.

CEZANNE APU is based on TSMC’s 7nm process technology, with a core area of ​​180 square millimeters, and the number of transistors has exceeded 10 billion, reaching 10.7 billion.

In contrast, the core area of ​​the Renoir APU of the Ryzen 4000 series is 156 square millimeters, and the number of transistors is 9.8 billion. Roughly speaking, the Ryzen 5000 series mobile processors increase the capacity of the third-level cache by 8MB and consume about 900 million transistors.

Here are some changes and new technical features of the Ryzen 5000 series mobile processors based on Zen3 architecture!

1. "4 times" L3 cache capacity

The Ryzen 4000 series mobile processors are based on the Zen2 architecture and use a single DIE dual CCX design. Although the L3 cache has a capacity of 8MB, each CCX has only 4MB L3 cache. The cache between different CCXs cannot be shared. In other words, each core of the Ryzen 4000 series mobile processors can only access 4MB of L3 cache at most.

Based on the Zen3 architecture, a single CCX design is adopted, and the three-level cache capacity is increased to 16MB, which means that the cache capacity that each core can access is up to 16MB, which is 4 times that of the Ryzen 4000 series mobile processors.

The available cache capacity of a single core of the desktop version of the Ryzen 5000 processor is only twice that of the Ryzen 3000 processor, which can increase the game performance by more than 20%.

The mobile version of Zen3 processor 4 times the three-level cache capacity increase on the game performance how much impact is hard to estimate.

2. CPPC mechanism

CPPC technology can greatly shorten the cycle of processor frequency switching, and can even achieve seamless switching, which greatly improves the response speed of the processor.

Most of the time, the working state of the processor is controlled by the operating system, such as switching from a sleep state to a working state, and frequency switching under different working states. Each switching takes about 30ms.

With the support of CPPC technology, the above tasks do not require the intervention of the operating system but are directly processed by the processor, and the time for switching working status and frequency is shortened to less than 1ms, allowing the processor to respond more quickly. The most important thing is to prevent to certain extent background programs from frequently applying for resources to cause multiple cores to be in a busy working state, which greatly reduces the operating power consumption of the processor.

3. Independent adjustment of each core voltage

For the Ryzen 4000 series and earlier mobile processors, regardless of the load, all cores and even cores display the same voltage. Even if only one core is used, the other cores that should be under low load are at high voltage. Go to standby.

The Ryzen 5000 series APU uses a new voltage mechanism to separate the voltage of the CPU core and the core display, and each core can independently adjust the voltage according to its current operating frequency, which greatly reduces the power consumption at low loads.

Ryzen 7 5800U can last for 17.5 hours of battery life in daily use, and 21 hours of use if you are watching local videos.

From the design point of view, the Ryzen 5000 series mobile processors have only made some fine-tunings on the previous generation products, but the performance and battery life have been greatly improved, and therefore have to admire the wisdom of AMD R&D engineers.

At present, a total of 8 Ryzen 5000 series standard pressure processors have been released, and two top models of Ryzen 9 5980HX and Ryzen 9 5900HX with the suffix HX have been added. These two processors not only have higher frequencies, but also support OEM manufacturers to set higher frequencies or higher power consumption by themselves, and even open overclocking functions to players.

The ASUS Sky Selection 2 gamebook we received this time is equipped with Ryzen 7 5800H processor, based on TSMC’s 7nm process technology, 8 cores 16 threads, base frequency 3.2GHz, acceleration frequency up to 4.4Hz, TDP 45W. However, this notebook also has a performance mode and an enhanced mode, which can increase the upper limit of the processor's power consumption to 65W and 71W respectively.

The GPU part has a complete 8 Vega CU units with a total of 512 stream processors with a frequency of 2000MHz. In terms of performance, it can beat the full blood MX250 discrete graphics card without much problem.

Tianxuan 2 gamebook tour: 240Hz + 100% color gamut screen

In this test, we used Asus' Tianxuan 2 gamebook. Last year's ASUS Tianxuan first released the Ryzen 4000 series, which was a great success. This year, we will continue to work hard. The second generation is still in the first list, using Ryzen 7 5800H processor and GeForce RTX 3070 graphics card.

Chosen 2 follows the design of the previous generation, with neat and domineering fuselage lines, and offers two exclusive color schemes: magic blue and eclipse gray. What we got is the eclipse gray version.

A 15.6-inch full HD IPS gaming screen with a three-sided narrow frame, 240Hz refresh rate, fast response time, 100% sRGB color gamut, support for DC dimming, and Adaptive-Sync adaptive tear-proof technology.

RGB colorful shadow blade keyboard, the keystroke is 1.8mm, and the 0.2mm key belly curve is adopted, which makes the user feel more perfect. At the same time, the buttons also use the Over stroke precise button technology, so that the peak pressure of each button is 62 grams, and the trigger is faster and more accurate, which brings players a faster and smoother experience.

From left to right on the left side of the fuselage are the power jack, Gigabit LAN port, HDMI 2.0, two USB 3.2 Gen1, one USB3.2 Gen2 Type-C (supporting DP1.4) and a headset all-in-one interface.

There is only one USB 3.2 Gen1 interface and security keyhole on the right side of the fuselage.

There are air outlets on both sides of the rear.

There are a large number of honeycomb cooling grids on the D side, and the air intake channel is larger than the previous generation Tianxuan.

20V*10A power adapter, maximum output power 200W.

The new generation of Ryzen 5000 series mobile processors have added some black technologies to enhance battery life. The Tianxuan 2 gamebook is equipped with a lithium polymer battery with a capacity of 90Wh. Let's use PCMark 10 to actually test the office battery life. During the test, select the energy-saving mode, turn off all other processes, and adjust the screen brightness to 50%.

The 12-hour battery life is amazing. This is the first time we have achieved such a high battery life in a gamebook. This number is even higher than most thin and light laptops. You must know that this is a gaming laptop equipped with a standard Ryzen 7 5800H processor and RTX 3070 mobile graphics card.

Summary: The best notebook processor

If you want to talk about the two most important indicators of a notebook, it is definitely performance and battery life! CEZANNE APU meets these two needs with a very perfect design.

In terms of performance, the Ryzen 5000 series mobile processors based on the Zen3 architecture use a single CCX design, while increasing the three-level cache capacity to 16MB. The result is that the available three-level cache capacity of each core is 4 times that of the previous generation, and the IPC is improved The amplitude exceeds 20%.

According to our test data, in terms of theoretical performance, the single-core performance of the Ryzen 7 5800H processor can be equal to the opponent's strongest i9-10980HK, and the multi-core performance can exceed the opponent by 9%. Don't forget that there are stronger Ryzen 9 5900HX and Ryzen 9 5980HX above the Ryzen 7 5800H.

As for the game performance, the past Renoir APU has some regrets, so that the Ryzen 4000 series gaming laptops can only be equipped with RTX 2060-level graphics cards.

With the support of the "4 times" L3 cache, the Ryzen 5000 series mobile processors are no longer the bottleneck of the system. The newly launched Ryzen is equipped with NVIDIA's strongest GeForce RTX 3080 and RTX 3070 mobile versions. , Since then, high-end games are no longer Intel’s world.

As for battery life, with the support of CPPC technology, the Ryzen 5000 series mobile processors can switch working status and frequency without the intervention of the operating system. The background of the operating system does not require a frequent application for various resource scheduling, which can greatly reduce the CPU usage under low load. rate. In addition, the Ryzen 5000 series mobile processors can also support each core to independently set the operating voltage according to its own load.

The addition of the above two black technologies greatly reduces the power consumption of the Ryzen 5000 series mobile processors and greatly increases the battery life of the notebook.

When the Tianxuan 2 game is equipped with a 90Wh battery, PCMark 10 actually measured 12 hours of battery life. This number is not only stronger than previous gaming notebooks but even stronger than most thin and light notebooks.

AMD told us that Ryzen could have reached 21 hours of local battery life, which is true!

Let's talk about this Tianxuan 2 gamebook, which is a gamebook designed by Asus! The 240Hz + 100% sRGB color gamut screen, the top NVMe SSD with AS SSD scores up to 6000 points, the top RTX 3070 discrete graphics card, and the most stringent MIL-STD-810H military certification, etc., all show that ASUS is for this The importance of this notebook.

The world is not only Intel, the spring of AMD gaming notebooks is really here!
