Although each generation of NVIDIA graphics cards will launch dedicated GPU graphics cards for laptops, compared with desktops, the performance is very poor, even only 50% or 60% of desktops. We have shared before RTX 4090 vs RTX 4090M performance gap. Therefore, players who pursue gaming performance will definitely dream about installing a desktop graphics card into a laptop, so that they can enjoy the highest gaming experience even when they go out.
Recently, an UP owner in China has successfully put NVIDIA’s most powerful RTX 4090 graphics card into a laptop. Not only has it passed the stress test, but the gaming temperature is only 70 degrees, which is quite stable. However, with such a large graphics card, the notebook body is unexpectedly thick and heavy. Taking it out is like doing heavy training.
The RTX 4090 desktop graphics card was successfully inserted into a laptop, but the weight of this power is terrible
A while ago, Xiaobai, the owner of China B site UP who loves overclocking, shared the super powerful gaming laptop they built. Not only does it have NVIDIA’s most powerful gaming graphics card RTX 4090, but the processor is also AMD 7950X3D, and it is equipped with 64G DDR5 memory and Intel Optane P5800X hard drive. The specifications are quite good.
Compared with other desktop graphics cards, it is very difficult to put the RTX 4090 into a laptop, because this card not only consumes high power, but also requires a powerful cooling system to run stably. Therefore, it is really impressive for a novice who loves overclocking to do this.
They did not share the production process from start to finish, only an internal photo, where you can see that the RTX 4090 graphics card is placed on the left, and the processor, motherboard and DDR5 memory are on the upper right. The speaker is actually quite powerful. It is actually a customized version of 20W x2, which looks very fierce:
After starting up and running, the GPU power consumption is about 460W:
The measured 3DMark Time Spy score was 28,490 points, and the GPU score was 36,426 points, which is indeed the same as the desktop version of RTX 4090:
Also passed the 3DMark stress test:
Next is the actual game measurement, the power consumption remains between 440W ~ 475W, and the temperature is 70 degrees. There is also no problem running AAA games for 27 hours continuously:
However, there is a weight with power supply shared later, which shows that there is no battery inside the laptop. The weight is as high as 8KG, which is really heavy. Even if the power supply is removed, it still weighs 6KG:
The thickness has also reached 7 centimeters. After all, the entire RTX 4090 is directly installed inside without any modification:
Although the laptop equipped with RTX 4090 is indeed attractive, it is so heavy, extremely thick, and has no built-in battery, so it is not that easy to carry it out for use. I can only say that I will do this just to fulfill a dream.
If you take this battery with you every day, you will soon have a bunch of muscles on your body, and walking every day will be a weight training exercise.
Xiaobai, who loves overclocking, also added that he will share more actual game tests in the future. Interested readers can go tohis channelTrack anytime.
What is the performance difference between RTX 4090 and RTX 4090 laptop GPUs?
According to previous actual measurement reports, the higher the image quality, the greater the difference between the two.
For example, in “Assassin’s Mission 3” Dubai in 4K quality, the RTX 4090 desktop version is up to 76.2% faster than the laptop version, and the average is more than 50%.
If you adjust to 1080p, the gap shrinks, and some games even perform about the same.
