Preface
When it comes to business notebooks, the public's impression of it, performance is generally not the main selling point, after all, enterprises consider more about the free customization of the machine, stability, after-sales support, etc., but with the development of technology and changes in daily use scenarios, business performance tuning has gradually paid attention to it. In March, Dr. Lisa Su, Chairman and CEO of AMD, and senior management and partners attended the AMD AI PC Innovation Summit, which featured a demonstration of laptops powered by Ryzen 8040 series processors.
Last year, the hard core experienced Lenovo ZhaoyangX5-14Ryzen version of this notebook,That will be equipped with Ryzen 7000 series mobile processor Ryzen 5 7530U,Recently, Lenovo Zhaoyang series finally launched Ryzen 7 8845H model,The most eye-catching thing is that the overall AI computing power has reached38 TOPS,Today the hard core will share with you the experience of using it these days。
Zhaoyang X5-14 Ryzen Edition 8845H appearance and configuration
Zhaoyang X5-14Ryzen Edition8845H adopts the obsidian black theme preferred by business peopleA-side,The material is alloy,The texture is finely frosted to the touch,Under the illumination of light,The surface can show a texture similar to that of a gemstone,This low-key、Texture-based style is indeed quite in line with the use scenario of business people,There is also a metal LOGO of Lenovo in the lower right corner。
In addition to the exterior design, the wear resistance of this material itself is also good, and it is not easy to get fingerprints. The laptop weighs only 1.38KG, which is as thin as 16.9mm, and it is not cumbersome to carry on business trips, and it is lighter and thinner than last year's Ryzen 5 7530U model.
The left side of the fuselage is equipped with 1*USB 3.2 GEN 2 full-featured Type-C, 1*USB-A (support shutdown charging), 1*HDMI, 1*full-featured Type-C and 1*headset two-in-one interface, first of all, it does not have a round-headed power interface, but through full-featured Type-C can be charged up to 100W PD protocol, if you want to use it on an external screen, such as PPT at a meeting, A full-featured Type-C cable can efficiently share the content on the screen, which is undoubtedly extremely friendly to business people.
The area on the right is corresponding to 1*-to-one card reader、1*USB-A port、1000M wired network port and keyhole these interfaces,The overall richness is very good to meet the needs of various workplaces,And here it can also reflect the importance of business books for the reasonable distribution of interfaces,For example, for some professionals who require high network security coefficient、Stable network speed or need wired network port for debugging,Wired network port is indispensable。
Zhaoyang X5-14 Ryzen Edition8845H can customize the screen,This one in hand16:10Golden ratioThe screen-to-body ratio reaches 90%14Inch IPS screen,The resolution is1920X1200Compared with the mainstream16:9It can provide a more delicate picture,The color gamut of the screen can reach100%sRGB,The maximum brightness can be supported400nits,And it has passed the German RyanTUV low blue light certification,It is a more mainstream parameter in the business notebook。
The top area is equipped with a PPC physical privacy camera, with dual noise-canceling microphones, after the video call meeting, you only need to swipe to turn off the camera, compared with your own system operation and shutdown, this single physical shutdown, will be easier to develop a habit of use.
The opening and closing angle of the screen supports up to 180°, which is convenient to share content with colleagues around you, improve work efficiency, and it can be opened and closed with one hand, silky and smooth without losing the elegance of the workplace.
Zhaoyang X5-14 Ryzen Edition 8845H key travel is suitable, the matte keycaps feel not easy to slip, and below is a large integrated touchpad, in addition to the power indicator, this notebook is also equipped with status indicators on the keys such as F1 (mute) and F4 (closed microphone), which is convenient for business people to quickly identify. Of course, the functions of keyboard backlight and power key fingerprint unlocking can also be customized.
D-side is also made of aluminum alloy,Enough to ensure the strength of the fuselage,Built-in Lenovo's original "wind blade" heat dissipation system,Let's briefly disassemble it,The fixing screws are divided into two types,The long screws are anti-falling design,So you only need to unscrew the four short screws at the bottom,Find the right position and pry it to open the back cover。
Zhaoyang X5-14 Ryzen Edition 8845H after dismantling the whole picture,The overall workmanship is quite regular,The memory and wireless network card part are treated with a metal shielding layer,It can play a certain role in auxiliary heat dissipation,The entire heat dissipation module is composed of two heat pipes + single fan,For the energy consumption ratio is excellent Ryzen 7 8845H is enough。
The laptop comes pre-installed with a GEN 4 SSD from SKhynix Hynix 512GB with a length of 2242 type, which is mounted on a 2280 M.2 slot with an iron patch length.
Lift the metal shield, you can see two sets of SO-DIMM memory slots, pre-installed two SKhynix Hynix DDR5 5600 16GB to form a dual channel, memory and SSD are SKhynix Hynix quality, sure enough, the business is the first to seek stability, and the top is a wireless network card that supports WiFi 6 protocol.
Below is the battery pack, the manufacturer is still BYD, the battery reaches a large 60Wh capacity, which can ensure battery life, and on the right is another set of GEN 4 M.2 slots, the type is also 2280 type, and both sets of M.2 slots support up to 2TB capacity expansion.
Zhaoyang X5-14 Ryzen Edition 8845H is equipped with a 100W power adapter, the volume is decent, it belongs to the two-stage separation design, and it is quite portable, but I personally recommend that it is more comfortable to bring a 100W gallium nitride charging head for business trips.
Theory and game performance measurements
HWiNFO64 system summary screenshot, Zhaoyang X5-14 Ryzen Edition 8845H overall configuration as above, the test environment is in a 25°C air-conditioned room, the machine is normally flat without pad height, and the heat dissipation adjustment is set to the default intelligent mode (the subsequent part of the link will involve the beast mode), which is more in line with the needs of business people.
Zhaoyang X5-14 Ryzen Edition 8845H is equipped with a Ryzen 7 8845H mobile processor that was only launched this year, it uses TSMC 4nm process to build, has eight cores and 16 threads, the maximum turbo frequency can reach 5.1GHz, L3 cache can reach 16MB, the default TDP power consumption is 45W, supports Ryzen AI engine, and the overall computing power reaches 38 TOPS, compared with the previous generation Ryzen 7 The 7840H is 3.5 times faster, with the newly added NPU (Neural Network Processing Unit) providing 16 TOPS, equipped with a Radeon 780M GPU, and the default allocated video memory is 4GB.
Zhaoyang X5-14 Ryzen Edition 8845H Heat Adjustment Settings Intelligent Mode,Ryzen 7 8845H's CINEBENCH R23 multi-core run score is 13822 pts,Single-core run score is 1740 pts,Multi-core performance is basically the same as most books equipped with Ultra 5 125H,And single-core performance is stronger,About 5% ahead。
Zhaoyang X5-14 Ryzen Edition 8845H heat dissipation adjustment setting beast mode, Ryzen 7 8845H CINEBENCH R23 multi-core running score is 14772 pts, single-core running score is 1748 pts, multi-core project improvement will be more obvious, the increase is 6.8%, single-core because it is a light load working condition, so there is no change, but it should be noted that this project is only a short-term high load, does not represent long-term performance, the following are all run in intelligent mode.
The standard SKhynix hynix 512GB GEN4 SSD, in the case of writing close to general data, the CrystalDiskMark peak performance Q8TI project sequential read speed is 5024.46 MB/s, the sequential write speed is 4616.30 MB/s, and the 4K random read and write IOPS are 825K and 616K respectively, the overall performance is at the upper middle level in the GEN4 SSD camp, and the 4K performance has not fallen. And the point is that the quality of the particles can be well guaranteed, and for business people, data stability must be the first place.
AIDA64 memory and cache test, DDR5 5600 16GBX2 combination, read is 61655 MB/s, write is 86895 MB/s, copy is 69351 MB/s, latency is 88.4ns, compared with the mainstream high-frequency LPDDR5 configuration, memory latency performance will be better, 32GB large tube after the purchase of the basic do not need to consider the follow-up memory upgrade problem.
3DMark Fire Strike theoretical project, the graphics card score is 8498, and the numerical value has perfectly surpassed the desktop-level GTX 1050 Ti 4GB, with a lead of about 11%, and it is completely okay to replace it, and the LPDDR5-7500 version is about 5% behind, in fact, there is no sense of gap in daily use, especially for business people.
The stability of the Fire Strike bake reached 98.1% through the 20-lap pressure test, and the core frequency basically runs on a slow curve, indicating that the core performance of the Zhaoyang X5-14 Ryzen Edition 8845H can be fully exerted.
THEN USE THE LATEST CINEBENCH 2024 PROJECT TO CARRY OUT A TEN-MINUTE MULTI-CORE ROAST ON THE CPU, AT THE BEGINNING RYZEN 7 8845H EACH CORE CAN RUN TO ABOUT 4.3HZ, CPU POWER CONSUMPTION RELEASE OF ABOUT 45W, IT WILL SOON FALL, AND FINALLY STABILIZE AT 3.5HZ AND ABOUT 35W, JUST LOOKING AT THE ABOVE DATA, THE CPU PERFORMANCE RELEASE STRATEGY OF THIS NOTEBOOK IS NOT AGGRESSIVE, BUT COMBINED WITH OTHER ASPECTS TO KNOW THE REASON FOR ITS DESIGN.
First of all, the CPU temperature can be controlled at a maximum of 75°C, which means that the noise is lower, and from the thermal imaging map, the maximum temperature point of the notebook shell (51°C) is at the heat dissipation port of the hinge, and the left side of the keyboard area will be higher, but it is only 40°C+, and it will not feel hot when you touch it.
Professionals also need occasional entertainment after work, and the machine's built-in Radeon 780M super core graphics can meet this need, and the first game tested is "PlayerUnknown's Battlegrounds", set to 1920X1200 resolution, ultra-high anti-aliasing, ultra-high material and ultra-high viewing distance.
In the old map Erangel, this machine can produce an average level of 80fps, and the utilization rate of Radeon 780M has reached 95%, indicating that it is fully under load, and the core frequency is about 2000MHz, and more importantly, the memory has also eaten up to 16GB, and the 32GB capacity redundancy equipped with the machine at this time is very large.
The second game is "Counter-Strike 2", set to 1920X1200 preset low quality, here the default will be enabled Fidelity FX super resolution equalization, the frame rate is capped at 1000fps.
In the desert II deathmatch, it can run an average of 142fps, which is a high frame rate level, and the intensity is higher than the general bomb disposal mode, after all, it is a multiplayer melee, this frame rate shows that the workers can also play happily, and the CPU performance is also more important, Ryzen 7 8845H multiple core frequencies can reach 4.1GHz.
The third game, "Elden Ring: Shadow of the Golden Tree", has just been launched, setting 1920X1200 preset low image quality, and you can see that the upper and lower areas of the game screen have black bars, because this game does not support 16:10.
In the scene of passing through dense forests and waters, this machine can run to an average of 41fps, and the frame rate is stable throughout the whole process when running the map, and the black edges up and down feel quite immersive in the movie~
In the battle with the wicker fire giant, the same average frame rate can reach 42fps, for this kind of game with a lock of 60 frames, the smoothness of playing with the controller is satisfied, and the keyboard and mouse experience may be slightly weaker.
AI performance demonstration
Don't forget, Ryzen 7 8845H has up to 38 TOPS of AI computing power, with the powerful Radeon 780M core graphics, that is, the use of CPU+GPU+NPU three modules to coordinate the completion of AI computing, a variety of AIGC and large language model applications are also its forte, let's experience the charm of AI PC through a few projects.
For mainstream consumers, even if there is software UI support, it is difficult for them to deploy a large language model, and on the Zhaoyang X5-14 Ryzen Edition 8845H machine, the factory has been pre-installed AMD Ryzen AI assistant, you only need to open the program to chat, and it is completely local deployment does not require networking, and you can use it at any time by turning on the computer.
You can see that the whole interface design is very refreshing, you can choose QWen-14B-Chat, Baichuan2-13B-Chat, CHatGLM3-6B, CodeGeeX2-6B and BianQue2 These models can be selected from above, each model is good at different fields, and the number of parameters is not the same (the above 14B is the largest, 6B is the smallest), you can choose the corresponding model according to the problem.
In the inference process of the BianQue-2 large model, CPU calls account for about 65% and GPU accounts for 15%, which is basically the answer in seconds
BianQue-2 is good at making health advice, such as asking it "how to improve leg strength", it will list as many suggestions as possible in the form of serial numbers, which is clearly organized, and of course, it will also remind you to consult a doctor or professional trainer before doing it, which is very thoughtful.
In the inference process of Qianwen-14B-Chat large model, CPU calls account for about 61% and GPU accounts for 16%, and this parameter is also the speed of seconds, which is the power of collaborative computing.
Qianwen-14B-Chat is more suitable for consulting in-depth and detailed questions, and the hardcore asks it "how to make a highly-rated development world game", which will help you summarize some ideas and explain them in more detail, and for game developers, it is also good to "brainstorm" with it to add some precautions.
Baichuan2 will be better at literature, so the hardcore asked it to "help me write a novel about crossing, 2000 words", its first sentence did not write it for me immediately, but pointed out that the knowledge base update period is 2023 (after all, this is a local deployment), the answer is quite rigorous, and when it comes to the knowledge base of large models, you can get the latest from the model publisher, and you don't have to worry about AI knowledge falling behind.
Looking at the novel written by Baichuan2 for me, no matter how you look at it, there is a taste of a time-traveling novel that is prevalent on the Internet~
Of course, if you are a novice programmer, you can consult it about the code through CodGeeX2-6B, and the chat window has listed Python, C++, java and other compilation languages for users, which is simply an artifact for copying homework!
If you need to use video calls for meetings, then Windows' built-in Integrated Camera is also a good AI application, which currently includes automatic framing, eye contact, and background effects.
And what really makes the hardcore feel powerful is eye contact, if you accidentally wander your eyes, the picture transmitted by the camera to the other party is corrected by AI simulation, and the simulated eyes are staring at the camera! If you usually hold meetings using third-party software such as DingTalk and Tencent Meeting, remember to check Integrated Camera on your device to enable AI effects.
TOPAZ PHOTO AI修正前的模糊老照片
TOPAZ PHOTO AI修正后的清晰照片
AI software for image processing,TOPAZ PHOTO AI IS A GOOD POPULAR APPLICATION,THE OPERATION METHOD IS ALSO SIMPLE,THE MODEL WILL BE AUTOMATICALLY DOWNLOADED WHEN YOU OPEN IT FOR THE FIRST TIME,LOAD THE PHOTO AFTER COMPLETION, IT CAN BE AUTOMATICALLY PROCESSED,IF YOU ARE NOT SATISFIED WITH THE PRESET EFFECT,YOU CAN ADJUST THE LOCAL PARAMETERS,WITH THE BLESSING OF RYZEN AI,IT COMPLETELY REDUCES THE TIME COST FOR USERS TO LEARN RETOUCHING。
FOR EXAMPLE, FOR THE LOCAL PROCESSING OF PEOPLE'S FACES, TOPAZ PHOTO AI CAN ACCURATELY RECOGNIZE EVERY FACE IN THE PICTURE, WHICH IS VERY FAST
Or if you need to eliminate some objects in the picture, as long as you delineate the size of the repaired area and set the highest possible quality, you can basically eliminate the objects perfectly at one time, saving the time of traditional PS manual repainting.
The above TOPAZ PHOTO AI is used for image processing,This TOPAZ VIDEO AI has the ability to repair and optimize videos,Hardcore generally uses it to repair some low-resolution "Cantonese fragments",Including frame insertion、Image two major repair models,The application is mainly used by GPU for AI acceleration,Let's take a look at the difference between Radeon 780M and the desktop GTX 1650 D6 4GB through the software's own benchmarks。
Radeon 780M 4GB输入分辨率1080P，各项模型的跑分性能
Desktop GTX 1650 D6 4GB input resolution 1080P, the performance of each model
The two most commonly used frame insertion models are Apollo and Chronos, compared to the GTX 1650 D6 desktop graphics card, Radeon 780M can lead by 2.5 times the performance, and in terms of image enhancement, the most commonly used Gaia model can also lead by 3.7 times the performance, in practical applications, the longer the video duration, the greater the advantage of Radeon 780M.
For gamers,Game plus software built-in2HaAIfunction is also quite practical,It currently supports super moment、AIGe-game coach and peripherals smart light control three functions,It is worth noting,These functions are all called NPU for acceleration,There is no need to consume any CPU and graphics card core performance at all。
AUTOMATICALLY CAPTURE THE HIGHLIGHT MOMENT VIDEO OF THE GAME KILL, GEFORCE EXPERIENCE SHOULD BE THE MOST FAMILIAR TO THE PLAYER GROUP, BUT IT REQUIRES A CERTAIN AMOUNT OF GRAPHICS CARD PERFORMANCE RESOURCES, AND THE GAME PLUS SUPER MOMENT, AFTER SELECTING THE AMD RYZEN AI MODE, YOU CAN USE IT TO CALL NPU ACCELERATION, LOSSLESS AUTOMATIC CAPTURE OF THE KILL VIDEO, COMPLETELY DOES NOT AFFECT THE PLAYER'S OPERATION AND OTHER PERFORMANCE, AND HAS BEEN SUPPORTED IN A VARIETY OF GAMES.
AI game coach, it sounds like improving the level of game technology, but the current version has not been updated to support, in the AI PC Innovation Summit exhibition area, the hardcore has seen the actual demonstration of "Naraka: Bladepoint", and it is indeed possible to reduce the difficulty of the game with the help of AI.
The last item is the peripheral smart lighting effect, that is, through AI analysis of key moments in the game, such as kills, blood loss, etc., so as to trigger the lighting effects of peripheral linkage, some video effects on the secondary screen, etc., such functions are not impossible to achieve on general machines, but they all need to call CPU or GPU performance, and calling NPU is completely 0 consumption.
Finally, of course, try the most popular AIGC application - Stable Diffusion AI painting, the application is also mainly using graphics cards to run, for AMD graphics cards, Windows system under the DirectML SDK, ZLUDA plug-in and Microsoft Olive converted to ONNX three ways to deploy, and for Radeon 780M is the most friendly is the first two, because you can use the Eishi modal package to get started.
DirectML SDK does not need to set up anything for Radeon 780M, after all, it is Microsoft's own technology, and ZLUDA is carried out by simulating CUDA, which requires the installation of the front-facing AMD HIP SDK, of course, Radeon 780M is not on the official support list, but it can be supported through private patches.
