AMD has launched a new generation of mobile processors: the Ryzen AI 300 series, which has significantly improved multi-core power efficiency compared to the Ryzen 8000 series, and can already compete with the HX processors ported from the desktop.
For details, please refer to the R23 performance curve in the figure below.
However, such strong multi-core energy efficiency also comes at a price, that is, more expensive prices, and many machines equipped with AI 300 series processors have been forced to "soar".
This includes the Lenovo ThinkBook 16+, which is a full 2,000 yuan more expensive than the R7 8845H version.
So in addition to the new CPU, what other efforts has this new 16+ made to "rush high"?
Today we will briefly analyze:

Left side of the fuselage
The right side of the fuselage
It is configured as follows:
AMD Ryzen™ AI 9 365 processor
32GB LPDDR5x 7500MHz 内存
1TB SSD
16-inch 3200×2000 resolution, 100% DCI-P3 color gamut, 165Hz refresh rate, IPS screen
The battery capacity is 85Wh
厚度 17.4~20.8mm
Weight 1.91kg
The adapter weighs 237g
The reference price is 7999 yuan
Its advantages and disadvantages are as follows:
Merit!
1. Rich interfaces and good scalability
2. The screen has good overall quality and supports color gamut switching
3. The keyboard layout is reasonable
Shortcoming!
1. Among similar products, the fuselage is heavier
2. Under full load, the fan noise is on the high side
3. There are more pre-installed software
【Upgrade Suggestions】
This laptop is not difficult to disassemble, and the back cover can be removed after removing the screws of the D case.
The dual-channel 32GB LPDDR5x 7500MHz memory meets the needs of most applications, and the memory is onboard and cannot be replaced.
The SSD capacity of the test machine is 1TB, the model is YMTC PC411, which supports PCIe4.0×4 and NVMe, and the machine has two 2280 M.2 slots, which can be installed by yourself if necessary.
【Purchase Suggestion】
1. High requirements for screen quality
2. There are certain requirements for the texture of the fuselage
3. Do not pursue the ultimate portability
Today's ThinkBook 16+ is not only equipped with the latest AI 9 365 processor, but also uses the 3K screen that was only available in the previous Ultra 9 version, equipped with a global pressure-sensitive touchpad, fingerprint recognition and TOF sensor (automatic lock screen when people walk, automatic unlocking when people come), it can be said that everything that can be on it.
In terms of screen, the measured color gamut volume is 98.1%DCI-P3, the color gamut covers 95.9%DCI-P3, and the screen supports color gamut switching:
Taking DisplayP3 as a reference, the average ΔE is 0.85, and the maximum ΔE is 1.81.
The average ΔE was 0.79 and the maximum ΔE was 1.46 with sRGB as the reference.
实测屏幕最大亮度约474nits。
In terms of interfaces, there is a USB-C 10Gbps (support 100W PD charging and DP1.4 video output), USB-A 5Gbps, HDMI2.1, USB4 (support 100W PD charging and DP1.4 video output) and 3.5 headset interfaces;
On the right side of the fuselage, there is an RJ45 Ethernet port, USB-A 5Gbps, SD card slot (UHS-I) and a hidden USB2.0 port.
In terms of battery life, the test score of daily application simulation script is 8 hours and 58 minutes.
In terms of noise, it has a decibel level of 49.3dB at full load. (32.9dB ambient noise)
Lenovo ThinkBook 16+ Ryzen AI Yuanqi Edition is priced at 7999 yuan in JD's self-operated version, which is already relatively cheap among AI 300 notebooks.
So if you want a large screen with a good screen quality, then this notebook can be considered.
But if you have a higher pursuit of cost performance, then the R7 8845H version may be more suitable for you.
【Heat Analysis】
The picture above is a real shot of the Lenovo ThinkBook 16+ Ryzen AI Yuanqi Edition, a combination of dual fans and dual heat pipes, which also adopts an internal blowing design.
Room temperature 25°C
Reflectivity 1.0
BIOS版本：PXCN20WW
For standard pressure processors, we use the Stress FPU for stress testing.
In the full load state, the performance mode is enabled, the CPU temperature is stable at 89.9°C, the power consumption is 65W, and the frequency of the large core (classic core) is maintained at 3.9GHz, and the frequency of the small core (compact core) is 3.0GHz.

Temperature on the back of the fuselage
The surface temperature is shown in the graph above, with the keyboard keycaps at a maximum temperature of 41.2°C for the "G" key, 35.2°C for the WASD key, and 33.4°C for the arrow keys. The temperature of the left wrist rest is 32.2°C, and the center point of the back is 36.5°C.
Overall, the Lenovo ThinkBook 16+ Ryzen AI Yuanqi Edition has a decent cooling performance, and although the 65W performance release is good, the noise is relatively loud in an integrated graphics laptop.
【The Pig King's Conscience Conclusion】
Objectively speaking, ThinkBook 16+ Ryzen AI Yuanqi Edition has made a lot of efforts to "rush high": 3K screen, global pressure-sensitive touchpad, fingerprint recognition, TOF, in addition to independent display, as long as it is the configuration that this mold can give, it has been given.
The price should have worked hard, as this is already the cheapest batch of AI 300 notebooks.
However, such a "rush" reflects the embarrassment of the AI 300 series in the positioning of the integrated display book:
When used in high-end products,
Its battery life is on par with the Ryzen 8000, which is not as good as the Lunar Lake, and it is difficult to play a multi-core performance advantage in an ultra-thin and light body.
When used in mainstream products,
Its price is too high, and it is difficult to support its price increase with 8845H by multi-core energy efficiency improvement alone.
It can be said that the two major advantages of "cost performance" and "long battery life" of the Ryzen 8000 series are not accounted for now.
In my opinion, the AI 300 series may be a really competitive category of thin and light graphics laptops, which are relatively high-positioning, can carry higher-positioned processors, and can also maximize its multi-core energy efficiency advantages while avoiding competition with Lunar Lake.
