Ever wondered if you can get desktop-level gaming performance from a laptop? Laptop gaming notebooks have gained popularity in recent years as more gamers prefer to play games at their own convenience and place. However, laptop integrated gaming GPUs usually have been limited and constrained by power and thermal limits, as the Mobile variant has been unable to match the performance of a desktop gaming GPU.
Compare Nvidia GeForce GT 740 Gainward One-Slot Cooler 1GB Edition & AMD Radeon HD 4730 graphics card Gaming performance vs system requirement comparison. AMD Radeon HD 8490 Graphics Card - Low Profile Graphic Cards E1C64AT. 4.0 out of 5 stars 18. Only 2 left in stock - order soon. More Buying Choices $39.00 (3 used & new offers) VisionTek Radeon 7750 2GB GDDR5 SFF Graphics Card, 4k 2 DisplayPort 1.2, PCIe, 7.1 Surround Sound, Included Full-Height Bracket (900942). Each GPU will feature 32 GB of HBM2e memory which should pump out 1.225 TB/s of total bandwidth. Rumor: AMD Navi 31 Will Be An MCM GPU Featuring 10240 Cores And 37 TFLOPs Of Graphics Horsepower.
So to circumvent this drawback we can connect an external desktop GPU/eGPU to any Laptop model which supports the Thunderbolt 3 interface. An eGPU is a separate device that houses a graphics card.
This device then connects to a laptop via Thunderbolt 3, and the laptop is then able to use the eGPU instead of its own onboard graphics to run games as well as other graphics-intensive programs.
The market for these devices is ever growing with many people seeing a lightweight laptop plus an eGPU as their preferred setup for not just gaming, but other tasks as well such as 3D modeling, animation, editing and computer-aided design/CAD.
Here is an example of a Thunderbolt 3 USB 3.0 External Graphics Card Dock from ASUS.
One of the downsides to using an eGPU is that even though Thunderbolt 3 provides the fastest connection right now, you still won’t get quite as much performance as you would if the GPU was housed internally. The loss in performance is said to be around 10-15% which isn’t too concerning, but it is still something worth mentioning in this context.
But what if you don’t want to buy an external graphics card dock, and want to use your current desktop GPU instead for gaming? Kosin which is a Chinese subsidiary of Lenovo has the answer. Kosin has demonstrated that there is another way to make a desktop GPU run on a Laptop.
Kosin employee shared a video showcasing how he managed to run an RTX 3090 desktop GPU off a notebook’s NVMe M.2 slot, coming via PC Watch. Yes, you heard that correct, via the NVMe M.2 slot! Kosin used a Xiaoxin Air 14 laptop with a Ryzen 5 4600U processor for this demonstration.
Kosin demonstrated how powerful and useful this type of connector can be, although going for this procedure is not advisable for normal users. In order to connect the desktop GPU to the laptop, Kosin removed the internal NVMe M.2 SSD and installed an “adapter cable” from M.2 to PCIe.
This allowed the modder, who also modified the laptop chassis to allow the cable to escape and run outside of the laptop’s chassis, to connect an RTX 3090 GPU to the laptop. The GPU was later recognized by the system without any issues.
So basically the laptop’s internal M.2 NVMe SSD was first removed, and an M.2 to PCIe expansion cable was then attached, which allowed the hardware modder to connect the RTX 3090 desktop GPU.
By drilling out a slot in the laptop’s housing allowed the PCIe cable to exit the chassis and a desktop external power supply was then afterwards attached to the RTX 3090 GPU to power it up. The modder used an 80PLUS Gold-certified 650W ATX power supply for the RTX 3090 graphics card.
The system booted correctly and the RTX 3090 GPU was also recognized properly by the OS. Surprisingly, the RTX 3090 performed perfectly well, even with just four PCIe lanes being fed to the card.
The system scored 14,008 points in 3DMark TimeSpy. For comparison, a standard RTX 3080 desktop GPU paired with a Core i9-9900K gets 15,000 points. An RTX 3090 GPU paired with a desktop Ryzen 5 3600 on the other hand can score 15,552 points, and 17,935 points when paired with a Ryzen 7 5800X CPU.
The modder was also able to play the Cyberpunk 2077 game without any major issues, even with RTX enabled. To quote PC Watch, via translation:
“It’s a performance to be aware of, but while it’s hard to say that the pci express band width has helped get the full performance of the GeForce RTX 3090, the 3DMark Time Spy test delivered more than GeForce RTX 3080 performance, and even with real-time rate-lacing turned on in Cyberpunk 2077, the game was smooth gameplay.”
So the overall score is still pretty good considering the specs of the notebook, and the downgrade to four PCIe lanes. The experiment served to show the potential of an M.2 NVMe connector. NVMe based M.2 slots run off pure PCI Express, so in theory, this mod can be implemented with little compatibility issues.1 Slot Amd Gpu Graphics
But this procedure should only be done by experienced hardware enthusiasts and gamers.
The x4 PCIe 3.0 link of the laptop’s M.2 slot handles a maximum of 4 GB/s. For comparison an x16 PCIe 3.0 slot reaches 16GB/s, while a PCIe 4.0 x16 slot can even reach 32GB/s, so you can imagine what you can currently achieve by laptop’s NVMe M.2 slot.

Hello, my name is NICK Richardson. I’m an avid PC and tech fan since the good old days of RIVA TNT2, and 3DFX interactive ’Voodoo’ gaming cards. I love playing mostly First-person shooters, and I’m a die-hard fan of this FPS genre, since the good ’old Doom and Wolfenstein days. MUSIC has always been my passion/roots, but I started gaming ’casually’ when I was young on Nvidia’s GeForce3 series of cards. I’m by no means an avid or a hardcore gamer though, but I just love stuff related to the PC, Games, and technology in general. I’ve been involved with many indie Metal bands worldwide, and have helped them promote their albums in record labels. I’m a very broad-minded down to earth guy.

When choosing an AMD GPU, you may notice the CrossFire parameter in the list of options. This is a special technology that was developed by AMD engineers to combine several graphics cards into one system. CrossFire technology gives you a possibility to extend the life service of old gGPU, as well as to increase the maximum power of the system several times. But the CrossFire technology has a lot of nuances that need to be kept in mind in order for it to work properly in a way that the graphics cards will reveal maximum of their capabilities. In this article we are going to tell you what are the subtleties of setting up CrossFire and combining several graphics cards.What is required to connect two GPU via crossfire
To combine two graphics cards into one, you will need not only their presence and two slots in the motherboard. There are several conditions that must be met in order to take advantage of CrossFire technology and unleash the potential of two graphics processors. Before combining two AMD cards through CrossFire into one common performance element, make sure that the following components meet the necessary requirements.
Motherboard. The motherboard must have at least two PCI-Express slots. At the same time, it is important that both slots are with maximum throughput. For modern motherboards, this is x16. You need to pay close attention to this matter. Only if there is x16 bandwidth for both graphics cards connected to the motherboard, you will be able to achieve maximum performance. Often, motherboards have one main x16 connector and several subsidiary ones with lower bandwidth. It can be x8 or x4. Some GPU do not have a PCI-Express slot with x16 bandwidth, and all their slots are x8.It is possible to use two x8 connectors (or one x16 and one x8) to connect AMD graphics cards through Cross Fire. But you need to understand that this will reduce the overall performance of the combined array.
Connectors’ capacity is marked with a corresponding inscription around them. If it is x16, it will say PCIEX16_1, PCIEX16_2, and so on. If it is x8, it will be marked as PCIEX8_1.
But it is not enough just to have two GPU connectors on the motherboard, it should support the CrossFire functionality at the chip level. It is important to note here that not all chips support CrossFire, and it is better to clarify the fact of compatibility on the motherboard manufacturer’s website. It is also worth noting that only motherboards that have AMD and Intel chips are able to work with the CrossFire technology. If the motherboard is made on an Nvidia chip (a company that is a direct competitor to AMD), it definitely does not support the patented CrossFire technology.Motherboards that support CrossFire have a corresponding designation on their boxes.
GPU. Ideally you should use two identical graphics cards – of the same series and from the same manufacturer – to combine them into an array through CrossFire. But this is not always possible, so on the AMD website, as well as on the websites of graphics card manufacturers, you can find detailed tables with compatibility of various graphics processors between each other. Important: If the cards are compatible to operate on CrossFire, but one of them is more powerful than the other, you should know that a more powerful model will not be able to fully reveal its potential. Both cards will work at the level of two weak cards from this pair.
It is worth noting that in the same package with graphics cards that support CrossFire, there will necessarily come a bridge that can be used to unite them. It is a small cable with the corresponding logo and connectors on both sides.Single Slot Amd Gpu
Power Supply. GPU is one of the main power consumers. When there are two of them, and they operate simultaneously, especially if both of them have x16 bandwidth, this is a very serious load on the power supply. It is necessary to choose the right power supply unit, and also take into account that it has to have a certain number of connectors to be able to connect all the components.
Case and cooling system. Another thing that people often forget about when they want to build a computer assembly with two graphics cards integrated through CrossFire is the presence of a good case. Graphics cards should fit into the unit along with other components as a start. And also case should have a good ventilation system. Us quotes about life struggles. It is wrong to think that coolers on the graphics card alone are enough to cool the chip. There should be maintained a low temperature, and when two graphics cards are working, it will be much higher than when there is only one. Therefore, the case must be equipped with its own high-quality coolers for the proper hot air output.
CPU, RAM and hard disk are not related to CrossFire technology. But, naturally, their performance must be at the proper level in order to unlock the potential of GPU.How to connect GPU via crossfire1 Slot Amd Gpu Radeon
The process of connecting GPU through CrossFire technology is extremely simple. There are only two stages:1 Slot Amd Gpu
*Hardware stage. It is necessary to install GPU in the PCIEX16_1 and PCIEX16_2 slots on the motherboard, as well as connect them to the power supply. As noted above, if there is no second slot with x16 bandwidth, you can install a second card (less efficient) x8 in slot. If the power of graphics cards requires it, they need to be connected to each other with a CrossFire bridge. Some models (those with poor performance) can work without bridging;
*Software stage. In the AMD Catalyst Control Center application, which is used to work with the parameters of all graphics cards based on the AMD chip, you need to go to the Performance section and the AMD CrossFire subsection. Here you need to check the “Enable AMD CrossFire” checkbox.1 Slot Amd Gpu Benchmark
At this point GPU connection and configuration can be considered complete. In games and applications that support CrossFire technology, you will immediately notice a significant increase in performance.
