Currently, it’s possible to embrace the full power of desktop-grade GPUs on an eGPU thanks to the latest technologies such as Thunderbolt 3 that provides bandwidth up to 40Gbps. All major companies have released their eGPU enclosures to try and create the best external graphics card on the market. Before the adoption of Thunderbolt connectivity in lots of high-end laptops, eGPUs never got the chance to take off due to the limitations of bandwidth when using USB 2.0 to connect the laptop to the eGPU. But now, Thunderbolt 3 offers bandwidth that provides four times the speed of USB-C.

What to consider when choosing the best eGPU?

Compatibility

As in the case of choosing any device for your PC the most important element to consider at first is its compatibility with your system. This ensures that you’re not going to invest any of your hard-earned money into a device that will prove useless. Our list provides you with information about the compatibility with Windows-based PCs, but the list doesn’t end there. Most notably, a good USB-C GPU dock will work on Mac, and iOS, thus enabling good portability.

Processing speed

What would a GPU be if it wouldn’t offer an efficient processing speed of the graphics that are required? The processing speed of your eGPU ensures not only that you won’t experience any sort of lag while working in demanding graphic software, but also that your gaming experience will be as smooth as silk. Even though it can be annoying to experience lag while working in Photoshop, the impact is a lot bigger if you’re playing online games professionally, and every second can literally mean the difference between the life and death of your character.

Number and type of ports

Even though the processing speed is a very important element, the next in line is the connectivity capabilities. This element is extremely important as well, as this is the bridge that connects the processing unit to your PC. When it comes to new devices, there are two main ways of connecting them, which are knows as USB-C or Thunderbolt 3. Because of the similarities of these two types of ports, it can get confusing. To clarify this idea once and for all, let’s first understand what are the similarities and also what are the differences when comparing an eGPU USB-C vs Thunderbolt 3 connection. eGPU USB-C vs Thunderbolt 3 Even though these two types of ports look almost identical, their capabilities are not the same. In fact, a USB-C cable can easily connect to a Thunderbolt 3 port and the other way around, but the results of the connection itself will be very different. Similarities: ➡ Both types of cables/ports allow you to use them both for transferring data, and power through a single cable connection. ➡ Both look exactly the same way, thus causing confusion for users who have devices without proper markings next to the port. Differences: ➡ USB-C only offers up to 20Gbps data transfer speeds and can muster about 100 watts of power to power/charge your devices. ➡ Thunderbolt 3 enables you to transfer data with speeds closer to 40Gbps, and can power/charge devices with a capability of 100W of bi-directional power. Key takeaways: Even though all Thunderbolt 3 cables and ports use USB-C, not all USB-C connections are also Thunderbolt 3. Because when it comes to efficiently using the capabilities of your eGPU, it is of course recommended that you have Thunderbolt 3 compatibility rather than the slower USB-C option. If you don’t have enough Thunderbolt ports available, then the connection will of course be affected, and thus the efficiency of the entire setup will suffer.

Cooling efficiency

If your eGPU gets too hot under extreme graphics processing loads, then both the quality and the smoothness of your gaming experience will be considerably affected. Some devices employ water-cooling elements to help with this issue, while others use powerful fans to considerably reduce the heat build-up. Not all cooling systems are the same though, and in the next point, you will understand why that is.

Noise production

Even though it is very important to maintain your eGPU’s temperatures under control, the method used to perform this action also affects the level of noise your device will produce. In the case of water-based cooling systems, the entire process is a lot more silent and offers the same cooling capacities as other variants. If your device is equipped with a fan-based cooling system, the sound of the device working at full speed might be considered bothersome in some cases.

Design

Last but not least, the way your device looks can make a huge difference to the overall experience. Because this element depends on your specific preferences, there are no special guidelines to discuss. That being said, a seamless box for your eGPU makes the device look a lot more stable and feel more sturdy while cooling vents on the sides will promote the efficiency of the built-in cooling system. At the same time, the cooling vents and their design also allow you a peek into the inner workings of your eGPU. All these elements considered, let’s explore what our experts concluded after rigorously testing a variety of devices available at this point in time on the market. These options provide a wide range of compatibility both for macOS and Windows-based systems, and also a wide array of GPUs. ➡ The entire list of devices presented here has very good graphics processing speeds, so choosing any one of them will provide you with enough speed to have a seamless gaming/ graphics software experience. ➡ When it comes to choosing an eGPU based on the cooling system, this choice comes bundled with your acceptance of the noise the device produces.
