Hi, I am Yitu Technology.
This article is dedicated to this article: Happy Fatty Home Qing Xiansen
When I mentioned flagship performance a few years ago, everyone's first impression should be that batch of flagship gaming laptops with exaggerated shapes, big black and thick shapes. Of course, large volume and exaggerated heat dissipation module stacking can ensure excellent performance, but the cost is that this high-performance laptop is basically only suitable as a replacement for ITX desktop hosts. There is mobility, but the biggest benefit it can bring is that it can be more convenient when moving. As for commuting or taking it to class, don't think about it. Even if you can bear this weight, it is hard to say whether the exaggerated look will cause you to become the focus of everyone. Many users who had this idea at the beginning bought an additional thin and lightweight card to undertake the needs of mobile use.
As people's requirements for the workmanship and texture and portability of laptops, the number of flagship gaming laptops with exaggerated shapes has decreased significantly in recent years, while the demand for high-performance mobile computing has not decreased at all. Fortunately, this year's 12th generation mobile platform has greatly improved the energy efficiency ratio with the new Intel 7 technology and new architecture, and it is possible to use the heat dissipation pile material of conventional laptop bodies to obtain flagship performance release. Today we will take a look at a product that has a flagship configuration under the shape and design of the conventional laptop - Lenovo Y9000K 2022.
Compared with the previous flagship gaming laptop with exaggerated design, the e-sports elements on Y9000K 2022 are only RGB light strips on the bottom and both sides. Of course, if you don’t like it, you can choose to customize the light effect in the control software of Lenovo or simply turn it off.
The RGB backlight of the keyboard is a must-have element for many performances now. In addition to being good-looking, it also has certain practicality when turning off the lights and playing games. If you don't need it, you can also customize the color, trigger method or simply turn it off.
core configuration is equipped with the 12th generation Intel® Core™ i9 processor 12900HX and Nvidia RTX3080Ti mobile version. In terms of the
interface, the back is equipped with a square power port (300W power adapter), a USB Type-Ch power supply data dual-purpose interface that supports up to 135W PD input, a standard-size HDMI interface, an RJ45 network cable port and two USB Type-A interfaces, two lightning/Type-C interfaces on the side, and the right is the Type-C+ extremely advanced 3.5mm headphone port. The interface is very comprehensive, just if you can place one of the Type-A interface on the side. If you only have the A port on the back, it is not particularly convenient to plug in and unplug a USB flash drive or something.
has top-level performance configuration, comprehensive interface, and also has good thickness control. It is slightly thicker than the height of a bottle cap, which is basically the level of mid-range performance notebooks in previous years. The shell texture of the all-metal CNC is also very good.
The most conspicuous thing after disassembling the back cover is the heat dissipation part. Instead of using a multi-heat pipe design, it is directly equipped with a full-coverage vacuum cavity heat dissipation board. Flagship-level CPUs and GPUs are both major heating users. The design of using a fan to target a module and then wearing it does not make good use of the entire heat dissipation area. heat dissipation board has become the standard configuration of flagship laptops.
After unscrewing the screw and removing the hot-smoothing board, you can see all the accessories inside. Let’s analyze the configuration installed in this notebook one by one.
heterogeneous, a battle of gods - the CPU part is equipped with the latest Alder Lake-H55 12th generation Intel® Core™ i9 processor 12900HX, which uses large and small core heterogeneous design. The heterogeneous architecture can better balance the dynamic needs between performance and power consumption.
However, this CPU is still a bit special. Unlike the previous SoC design of BGA integrated packaging CPU and PCH, the DIE used by this CPU is exactly the same as the desktop LGA1700 processor (the one with the comparison on it), and the scale is also the complete core of 8C+8c+30MB L3.Since the Alder Lake-S of the desktop only integrates the north bridge part and the PCH needs to be placed separately, we can see this independent PCH chip that is not very common on laptops below the motherboard. In terms of heat dissipation media, I believe everyone can see at a glance that liquid metal is used instead of silicon grease , and there are corresponding parts on the heat dissipation module to prevent liquid gold leakage. In terms of
GPU, this time the 3080Ti mobile version is the core of the laptop platform. The code name of GN20-E8 is GA103, and there are currently no corresponding products on the desktop. The video memory is equipped with eight Samsung 16Gb 16Gbps GDDR6s, forming a 16GB 256bit video memory specification. Compared with the 320/384bit GDDR6X bandwidth of the desktop 3080 and 3080Ti, it is definitely incomparable, but considering the power consumption of GDDR6X, it is probably very difficult to use a laptop. In addition, the laptop card does not have the demand for 4K gaming as hard as the desktop platform, and the lower bandwidth should not have a particularly big impact.
memory is two independent Hynix 16GB 4800Mhz DDR5, it is a pity not to use the latest JEDEC 5600 memory. However, considering that Alder Lake's official JEDEC support is 4800, it is estimated that Raptor Lake will not be equipped with 5600 memory support until next year.
SSD is Samsung PM9A1 1TB. There is nothing to say about this, it’s an old acquaintance.
wireless network card is a rare Killer AX1675, which is actually the vest of AX210, and supports WiFi 6E specifications. The advantage is that Killer's driver support will be much better, and theoretically, the game delay will be lower. Of course, if you think the delay is still not low enough, you can use the RJ45 interface behind it to connect to the wired network.
The lower left corner is PCH, 6+2 phase graphics card power supply and another m.2 interface , which can be extended to an m.2 SSD.
The old rules in performance testing Let’s first look at the theoretical running score of the CPU. The CPU-Z version used by
is a bit old and is directly identified as the i9 12900 of the LGA1700 platform, but it doesn't matter anyway, there is no essential difference between the two. In terms of specifications, you can see 16 cores and 24 threads, which is consistent with desktop i9.
CPU-Z running scores are about 750 single cores and 9600+ multi-cores. On the desktop platform, it is basically at the level of i7 12700.
memory cache performance, DDR5 4800c40 Gear2 bandwidth performance is OK, with a slightly high latency. I look forward to the next generation standard DDR5 5600 that can make some progress.
Cinebench R23, multi-core about 21500, single-core 1900, which is almost the level of desktop i7 12700K.
graphics card performance test, GPU-Z can fully identify the 3080Ti mobile version, equipped with 7424 FP32 CUDA Cores, the maximum design power consumption can reach 175W with the support of Dynamic Boost, the video memory works at 16Gbps, and the bandwidth is 512GB/s.
3DMark Time Spy running score, the 2K resolution GPU scored 13126. According to the performance promise at Nvidia's press conference, this performance has indeed reached a higher level of the public version of Titan RTX or 30 series desktop 3070. The performance release of the notebook is limited by the severe power consumption, and stoves such as GA102 will definitely not be plugged in. Everyone is competing for performance at the power consumption level of 175W, and it is expected that it can reach this performance level. In terms of Time Spy Extreme, the 6421's GPU score is also comparable to the 3070 desktop version, and is a certain distance from the 3080 or even the 3070Ti. The 4K resolution score is much more significant than that of 2K due to bandwidth and power consumption. Fortunately, the screen paired with Y9000K is 2K 165Hz, and the 4K gaming performance is nowhere to be performed without an external screen, so just look at it.
AIDA64 GPGPU test, single-precision floating point performance is about 25TFlops.
Next, let’s run a few actual games to see the game performance of this set of combinations. The resolution is all 2560×1600 by default, and the picture quality is the highest preset for each game.
Cyberpunk 2077 Preset ray tracing advanced image quality DLSS automatic 46.7fps
God of War 4 Preset super image quality 66fps
Subway: Departure Extreme preset 39.49fps
Tomb Raider: Shadow Highest preset 107fps
Fighting the Three Kingdoms 65.2fps
Killer 3 108fps
Overall, the performance of the 3080Ti mobile version is completely sufficient in pure rasterized rendering games, and even older games can fully run to 100+fps e-sports level frame rate . However, it is more difficult to deal with ray tracing games. Turning on DLSS only ensures the frame rate that can be played. If you want to run smoothly, you have to lower or even turn off ray tracing. Indeed, ray tracing is still a bit luxurious for today's laptop platforms. I look forward to the new TSMC process's 40-Series graphics card energy efficiency ratio that can improve significantly, and can bring better performance under the power consumption limit of 175W.
productivity performance testing According to Internet conventions, the highest productivity is the most productive, so we also tested the performance of PS, PR, and LR.
Windows laptops can finally have LR/PS 1100+ and PR 900+ Pugetbench scores. This score is basically the same as the mainstream Zen3 and 12 generation platforms on the desktop, and there is no problem dealing with complex photo editing and video editing applications. The actual 100 million pixel GFX100 16bit RAW file is also very smooth.
power dissipation, in terms of power dissipation, single-copy FPU can reach about 150W of CPU power consumption at the beginning, and then stabilize at around 125W. At this time, the large core frequency is about 3.6G and the small core frequency is 3.1G. If you copy the graphics card, it will take up 150W of power consumption, and the CPU power consumption is limited to 95W. At this time, the large-core frequency is 2.4G and the small-core 1.9G. The heat dissipation is completely OK, enough to suppress the overall power consumption of about 250W. Considering that the thickness of the Y9000K is not exceeding the standard and the noise is not very large, this heat dissipation performance is quite surprising to me.
Finally, the battery life test... emm, the battery of the gaming laptop can be used as a UPS, don't expect it to have too good battery life.
summary, to be honest, there should be no shortcomings in using the laptop in this configuration. This is the top limit of this generation of Intel+NVIDIA platform. With the 300W power supply input and the cooling module that can suppress 250W+ heating power consumption, it can be compared with contemporary mid-to-high-end desktops in gaming, productivity and other applications. At the same time, the new heat dissipation and mold design also make it portability not inferior to traditional performance books. Whether it is a mobile gaming platform or a mobile workstation, the only disadvantage may be that the battery life is urgent, but users who buy this positioning laptop should have a clear understanding of the expected battery life of this type of platform, and generally it will not be used for a long time. If you compete in cost-effectiveness, it still has a considerable disadvantage compared to compact ITX desktops. After all, no matter how small the independent ITX chassis is, it is based on 10 liters. The degree of heat dissipation and power supply margin is obviously much larger, and it is unlikely that it can be used everywhere. The performance of the 12th-generation Core platform with the top mobile 30 series graphics cards is already very satisfactory, which makes me look forward to whether the 13th-generation +40 series after the new optimization and polishing and process replacement will bring new surprises in terms of performance and energy efficiency on top platforms.
