Best External Graphics Cards For Laptop in 2021

Best External Graphics Card For Laptop

Desktop and laptop both can be used for gaming, but the thing which gives desktop machines an advantage over laptops is the future upgrades options. With time, we can upgrade our desktop machines with new processors and graphics cards, but this thing will not happen on laptops soon.

With time the manufacturers make laptops getting some future upgrades, but that’s only limited to hard drives or memory modules. There we can’t leave laptops because they are portable and allow us to do gaming from our bed to college and on the park bench. 

There is a frequently asked question: how can we upgrade our laptop’s graphics card to play some modern titles? Or at least some Esport games? The simple answer to this is that we can’t upgrade the existing graphics card but can attach external ones to get more performance out of them. 

We are there with some of the best external graphics cards for laptop machines that you can consider buying, and they will enhance your gaming experience. You might already know the importance of a graphics card in any gaming machine. When we see the laptop specifications, the latest generation high-end models even come with integrated graphics cards. 

Before checking out the graphics card raisers, let’s check out what we need to consider before buying an external graphics card box. 

Graphics Card Support:

The first thing we need to consider in any external graphics card box is the support for different graphics cards. Some market models don’t support Intel graphics cards, which some don’t handle AMD GPUs very well. I’ve seen some users willing to install workstation graphics cards with these raisers, but lack of compatibility disappoints. All you need to do is check if the raiser box supports Nvidia or AMD graphics cards.

Power Supply Unit:

The power supply is another major thing to check because the graphics cards we need to install require cables like 8-Pin or 6-Pin etc. There we need to make sure that the pre-installed power supply can handle our graphics card or not, or it has all the required cables or not. Some models come with 350 W PSUs; that’s not enough to run high-end graphics cards, so consider this. 


Of course, if you own a laptop, you don’t attach it with some external display and play games. Most users consider laptops because they are portable and allow you to carry them anywhere you want. Make sure if you have to take your computer outside, your eGPU box is compact or not. There are some specific boxes for those who like to carry them in bags as they are small and have batteries installed.

Alienware Graphics Amplifier

Alienware Graphics Amplifier (9R7XN)

Alienware is known for manufacturing actual gaming laptop machines; of course, they will not perform and upgrade options like desktops but are relatively equal to them. Most of the laptops from Alienware give more than average gaming performance, and if you compare the top gaming laptops of 2021, this brand stands first on the list.

The company is not only known for gaming laptops but some other hardware too, and today we’ve got an Alienware Graphics Amplifier, which allows you to connect external graphics cards with any Alienware machine. It comes with a power supply and a PCIe x16, which will enable you to install any graphics card. 

This box’s primary use is to give you some extra space for some external graphics card, and you can connect it with your laptop to get a significant performance boost. We can use it with desktop or laptop machines, and the installation process of this one is damn easy.

While checking some reviews on Amazon, I’ve got that many users criticize the design of this eGPU box, and that’s true because there are some more attractive options in the market. This eGPU box’s shape seems like a bread toaster with some vents on the top and front sides. 

The good thing about this eGPU box is that it’s a bit old but still supports every latest graphics card and doesn’t limit the performance. You can install any Nvidia or AMD graphics card on it, and the most commonly used ones are Rx 470 or GTX 1070 from Nvidia. If you have some more budget for graphics cards, you can even go to Turing-based cards. 

There are a few more things in this small box, including four USB ports, a built-in 450 W PSU, some RGB lights with significant effects, and more.

Sonnet eGFX Breakaway Box 650

Sonnet eGFX Breakaway Box 650 (GPU-650WOC-TB3)

Unlike the Alienware Graphics Amplifier, this one is not limited to one brand, but you can use it with any laptop machine and install any AMD or Nvidia graphics card. If you are looking to get some more gaming performance on your laptop or tired with lags and shuttering in games, that’s a great hardware piece.

Gaming laptops are quite expensive than any regular machine, and most users prefer the cheapest machine. In this case, this GPU raiser is great enough to play Esports and some modern titles without spending a lot of money. Also, it’s not heavy so you can take it anywhere you want. 

This box’s thermal design is no doubt impressive as in an eGPU box; we need much cooling because of the small casing. Sonnet eGFX Breakaway Box comes with some pre-installed fans while there is also some space to install AIO cooler radiators for better cooling of the graphics card. 

Non-techies found it hard to change the graphics cards in these boxes, but you can easily do it by pulling off the top cover. Those who are willing to overclock the graphics card in this box will also find it an excellent choice because of its perfect thermal design. 

These raisers’ performance is slightly lower than using the graphics cards on the desktop machines as the company claims that it has a data transfer speed of 4GBPS. This gives you a great gaming experience without facing any lag stuttering in modern titles.

Some fans and a 350 W PSU come pre-installed with this eGPU box, and you can change them according to your own power needs.

HP OMEN Accelerator Shell GA1 1000

HP OMEN Accelerator Shell GA1 1000

Again we’ve got a brand-specific graphics card raiser box, but this one is much better than the previous one as that one was an old model. HP OMEN Accelerator Shell GA1 is portable, and it will help you get some more performance from your machine. This box is built for hardcore games that don’t want to compromise on graphics card performance. 

As you know, this product is directly coming from HP, so we don’t have to worry about the build quality or this box’s performance. Though it’s slightly more expensive than other raiser boxes in the market, I recommend you get this one if you can afford it because of its remarkable features and design. 

This box supports every single AMD and Nvidia graphics card, and that’s what makes it a better option over others. However, some cards might not work with it, so it’s good to check out the manufacturer website first to get its compatibility list. The company claims that this eGPU box has support for more graphics cards than any other competitor. 

The installation of a graphics card on this box is better and comfortable than any other box as it comes with a door, and you can easily slide in-and-out the GPU from it. There is a pre-installed power supply in this box that comes from HP itself, and it can easily handle any graphics card you can think of in your mind. 

Some other notable features of this box are a slot for 2.5 inches of SATA drive, and you can install an SSD drive. There are few USB Type-A ports on this box, too, which works when you connect this box with your laptop. 

Overall it’s a fantastic product from a very reputed brand, and we can consider buying this for our laptop to get some more performance out of it.

Akitio Node Thunderbolt 3

Akitio Node Thunderbolt 3 eGPU for Windows

When it comes to buying the cheapest eGPU box in the market, there might be no other better option than the Akitio Node Thunderbolt 3. This external graphics card box is cheap, but you don’t have to compromise on features with it as it has everything you need. The graphics card has a pre-installed 400 W power supply, which gives continuous power to the GPU installed.

This amount of power is enough for any mid-range graphics card but don’t expect to install RTX-based graphics cards on it as they demand 600W of power. This eGPU box’s compatibility is excellent enough as it supports most of the Nvidia and the AMD graphics cards in the market. 

This box is compatible with both Windows and Mac devices, but on Mac, you may see some performance difference compared to Windows. The performance loss of this box is minimal, and you will see the same performance of the graphics card installed on Windows. When this box is connected with Mac devices, you can only use AMD graphics cards with it. 

As we have seen that the EVGA graphics cards are a bit wide and use more than two slots on the back, so this box has an advantage in such cases as its side panel is removable, and you can install 2.5 slot graphics cards on it. This case’s portability is also excellent as it has a carrying handle on the top, and you can carry it wherever you want. 

The main thing to see in an eGPU box is its performance, and with this one, you will use the Thunderbolt 3, which has a data transfer speed of 40GBPs. So a cheap but yet great option with such features makes this eGPU box the best on this list.

Gigabyte AORUS Gaming Box GTX 1070

Gigabyte AORUS Gaming Box GTX 1070 Graphic Card

Users who are very brand conscious can try the Gigabyte Graphics Card box, which comes in a great-looking design and fantastic build quality. This external graphics card box gives better performance than any other in the market. It comes with a pre-installed GTX 1070 graphics card, much better than the integrated graphics card. 

With 8 GB of dedicated memory, you can get the best performance in any game and max out most of the titles.

ASUS ROG XG Station 2

ASUS ROG XG Station 2 Thunderbolt 3 Graphics Dock

Another grand entry from a well-reputed brand and yes is the ASUS ROG XG Station 2, which comes with Thunderbolt 3, having data transfer speed up to 40 GBPS. This small box allows you to max out in-game settings at high resolutions if you own a good graphics card, and it’s coming straight from ASUS, so no need to worry about the hardware inside it. 

Previously we’ve seen eGPU boxes with detailed looks, but this one looks more attractive than the others because of the red and black color combinations and some cuts. It has some beautiful finish on the front side and an RGB light, making it more appealing. This box’s design gives a feeling of ASUS Rog series graphics cards because of the color and detail.

All you have to do is install the graphics card on the PCIe x16 slot and you are done with it. 

Asus also worked well on this box’s thermal design as it has enough room and airflow to cool down the latest graphics cards at high loads. However, these raiser boxes can’t minimize the noise of the fans of graphics cards very well.

Gigabyte Aorus Gaming Box With GTX 1080

Gigabyte Aorus Gaming Box With GTX 1080 GPU

Last on our list, we got another Gigabyte Aorus graphics card box, a pre-installed graphics card, and a power supply. You will get a GTX 1080 graphics card in this box, which you know is slightly cheaper than Turing-based graphics cards, but its performance is way better than their entry-level models.

Other than video output, some other ports are on this box, including the three USB ports to connect the external keyboard and mice, a USB storage mic and headphones, and an Ethernet port. 

Another great feature of this box is that it even works without electricity, as it comes with some batteries.

  • Using this is much better than having an integrated graphics card.
  • Very easy to connect with just a single cable.

  • Comes with a compact design.
  • Fan noise becomes high when running on a 100% load.

Gaming on a laptop machine is not a big deal because of the high-end hardware and external graphics card boxes for them. There we’ve reviewed some of the best external graphics cards for laptops you can get and use to replace your integrated graphics card. All you need to do is get a good graphics card and install it in this box, and it gives you an enhanced gaming experience. Several models are available, but the one we’ve mentioned there are best in every term and gives you more value than others. 

Let’s start with the cheapest model in this list, and this award goes to the Akitio Node Thunderbolt 3 eGPU for Windows, but of course, it lacks some premium features for the low price too. Those who got an Alienware machine can consider getting an Alienware Graphics Amplifier, but it is only compatible with the Alienware 13, 15, and r2 17 machines. If you are looking for something from a well-reputed brand there, we have the HP OMEN Accelerator. Non-techies who are looking for a plug-and-play device can go with the Gigabyte Aorus Gaming Box, which comes in several different models, including the GTX 1070, GTX 1080, RTX 2060, and more. 


External graphics cards are a new concept for laptop machines to connect a desktop GPU with some raiser cable help. This is much better than using the integrated graphics card on laptops as they enhance your gaming experience without spending a lot of money on gaming laptops. One thing to note there is not every laptop in the market is compatible with this graphics card, and some eGPU is only compatible with manufacturer same as of it.

Those users who can afford a high-end gaming machine don’t find eGPUs a good thing for their laptops. But if you own a mid-range machine and don’t have enough money to upgrade it to the latest-generation hardware, you can use a GPU, and they will allow you to get the same graphics performance as found in the latest gaming machines. The performance loss of external graphics card boxes is very minimal while, on the other side, it allows you to game on thin, lightweight machines.

Almost every eGPU connects to a laptop with Thunderbolt 3, and you might already know that not every laptop has this port. Thunderbolt 3 requires USB 3.1 Gen2 port and a chip to operate. That’s the reason why these external graphics cards are not compatible with every laptop in the market. Though if your computer supports the one you can do it with play and play.
