[Material evaluation] Double baking+4K video clip double test HP Star 14 Pro meets the challenge perfectly

Flimsy edition Can you "do heavy work"? Two or three years ago, the answer was yes, but the efficiency was too low. For example, if you use a low-power processor slim notebook three years ago to cut 4K video, it may take more than 20 minutes to render a 10 minute or so piece. But if you put it today, it may only take a few minutes to complete. with HP Star 14 Pro A series of high-performance light-weight books represented by high-performance light-weight books are really capable of "doing heavy work".

The fundamental reason lies in the significant improvement of hardware performance. In particular, the current CPU and GPU have added more instruction sets for heavy load tasks, and even improved efficiency by introducing AI technology, which makes the performance weakness of thin and light notebooks be supplemented. So when we look at the thin and light version, we will not ignore its performance because of its thin and light design, because it is likely to be a moving productivity cannon.

For example, HP Star 14 Pro recently launched by HP can select the twelfth generation Intel Core i7-12700H standard pressure processor at most, and can select the RTX 2050 light pursuit independent graphics card at most. It provides users with excellent productivity while designing a slim body, thus further amplifying the value of thin and light performance.

At the same time, more importantly, the HP Star 14 Pro, through its good thermal design, enables the CPU, GPU and other core hardware to maintain efficient performance release for a long time. This is the most critical difference between the current thin and light edition and the previous thin and light edition.

We all know that, Notebook computer The biggest "enemy" is heat dissipation. If heat dissipation is not good, everything is useless. In the past, the weak performance of thin and light notebooks was not due to the weak performance of CPU and GPU itself, but because of the consideration of heat dissipation, manufacturers often need to significantly reduce the hardware power consumption to control the temperature during design. What the user perceives is slow, stuck and slow.

How about the heat dissipation performance of the thin and light notebook? Let's take HP Star 14 Pro as an example to see the whole picture. (Actual configuration: the 12th generation Intel Core i5-1235U processor+RTX 2050 ray tracing version)

At the room temperature of 26 ℃, we conducted a continuous baking machine of CPU+GPU for 21 hours and 48 minutes on the HP Star 14 Pro. During the whole process, it left the author two very deep impressions:

First, excellent stability.

The second is the performance of heat dissipation efficiency.

In 21 hours and 48 minutes, although the CPU and GPU were under high load for a long time, the system and software of HP Star 14 Pro were running smoothly without any problems. As shown in the figure below, the CPU and GPU core temperatures are 68 ℃ and 75.5 ℃, respectively, which are kept in a very ideal state. HP Star 14 Pro adopts a new frost cooling system. The size of the upgraded ultra-thin fan has increased by 36% and the airflow has increased by 84%. The design of double three-phase motor fan and double wide heat pipe can take away heat more quickly, so that the equipment can keep cool and fresh during high-energy operation. This is the fundamental reason why the HP Star 14 Pro is slim in design but excellent in performance and efficiency.

At the same time, under such a long period of continuous baking machine test, HP Star 14 Pro has not experienced any problems such as sticking, blue screen, and crash. Its stability performance is extremely excellent, so it can also give full play to the performance of the 12th generation Core processor and the RTX 2050 optical tracking independent graphics card.

about notebook As far as computers are concerned, heat dissipation is like a cornerstone supporting the operation of the whole system. Good heat dissipation performance can not only avoid problems such as sticking and slowness, but also bring about continuous high-performance output state. For example, video rendering generally takes a long time. At this time, the continuous performance output of the computer is particularly important.

If your computer is about to explode in the first five minutes, and the CPU and GPU frequency drops due to the temperature hitting the "warning line" five minutes later, then the performance output of such a computer will not be sustainable.

Now let's use HP Star 14 Pro to export H.265 4K video through Adobe Premiere software. We use 4 segments of high bit stream 4K video to splice together and output it as a whole segment of H.265 4K UHD video for about 13 minutes. From the actual rendering process, it only took more than 6 minutes for HP Star 14 Pro to complete this task. Two to three years ago, it was unimaginable that thin and light could have such high video editing efficiency.

At the same time, we also see that during the whole task execution, the CPU temperature is basically around 64 ℃, and the GPU temperature is only 71.9 ℃. The continuous good cooling state also ensures that the Star 14 Pro can bring excellent efficiency when facing high load tasks such as video editing.

Then, we used Media Encoder software to transcode this H.265 4K UHD video. It took only 3 minutes and 56 seconds to complete the task, and the efficiency is unknown.

The reason why HP Star 14 Pro has such good heavy load task execution efficiency is that the 12th generation Intel Core processor and RTX 2050 have made outstanding contributions. The former has many mainstream video codec instruction sets, and the latter has a powerful CUDA acceleration function. As long as you turn on the GPU CUDA acceleration option shown in the following figure of the GPU when processing video, you can also obtain a flying video processing efficiency.

In addition to excellent performance and reliable cooling performance, HP Star 14 Pro has a more appropriate dessert function for visual productivity applications such as video clips, that is, the OLED eye protection full sense screen with outstanding effect. Compared with the LCD screen carried by ordinary notebook computers, OLED screens have a wider color gamut and higher brightness due to the self luminous property of their pixels. Its DCI-P3 color gamut reaches 100%, and the color range is 25% larger than 100% sRGB. In addition, the Adobe RGB color gamut is 96%, and the NTSC color gamut is 95%. The overall color gamut covers a wide range. For productivity users who focus on visual experience, there is no pressure to complete professional visual content creation through HP Star 14 Pro.

In terms of auditory perception, HP Star 14 Pro can be rated as the top. First of all, its sound system has a good foundation. It is adjusted by the professional Danish audio manufacturer B&O. Through the stereo dual speaker design and Audio Boost audio enhancement, it brings users precise and broad stereo sound effects, and makes the sound output effect more powerful. When playing games or video entertainment, HP Star 14 Pro will give you a sense of reality and immersion of "sound".

In addition, for young people who like novelty, the newly upgraded Huixiaowei Voice Assistant It will bring you many surprises. Huixiaowei supports intelligent services such as subtitle translation, voice input, and meeting notes. At the same time, it can also provide real-time bilingual subtitles, record audio content synchronously, and support text transfer after video or voice conferences. These AI based functions can bring you a new interactive experience, help you greatly improve your work efficiency, and fully interpret the meaning of science and technology.

Recently, the HP Star 14 Pro high-performance slim book discount continues, and the price is only 4999 yuan per second. If you want to get on the bus, please hurry up.
