10 Best External GPU Enclosures (eGPU) You Can Buy

Last Updated: July 7, 2017

We are in an era where each day new technological enhancements are being made, and existing technology becomes obsolete day by day. As such, upgrading to the newest technology has become a necessity for everyone. The new advancements aren’t a choice but are rather being imposed onto us. In the aspect of upgradations, laptops generally fall back. Closed circuitry and embedded chips make it hard for a laptop to be upgraded. While the internal HDDs/SSDs can still be upgraded, internal components such as the GPU remain embedded onto the motherboard, making it impossible for them to be upgraded. This is where External Graphic Card Boxes or eGPUs come into play.

What is An External GPU Enclosures or eGPU?

An eGPU or External GPU is essentially a piece of hardware enclosure in which a desktop graphics card can be mounted to be used with your laptops for powering up applications and games. Desktop GPUs are far more powerful than integrated mobile GPUs or APUs and offer up to 10x performance improvements over them. While eGPUs have been around for years now, their functionality has been greatly limited due to the slow connection speeds and low transmission bandwidths. But when Intel announced Thunderbolt 3, the game entirely changed.

Thunderbolt 3 is a USB-C type port that supports a Max Bandwidth of 40 Gbps, thus helping external graphics cards achieve their aim of supercharging a laptop. If you have a laptop that doesn’t satisfy your gaming desires but has a Thunderbolt 3 port, then check out our list of 10 best external graphics card boxes you can buy:

Best External GPU Boxes You Can Buy

1. Razer Core

Starting off with the most famous eGPU, we have Razer’s Core. Launched alongside Razer Blade Stealth, this external graphics card box is also available as a standalone product that can be paired with any device which has a Thunderbolt 3. The Razer Core is one of the most power consuming eGPUs, requiring a 500W PSU. It is quite heavy too, weighing at 10.89 lbs. While the portability of this device is limited, the features it offers, on the other hand, make up for the loss of its mobility.

Razer Core a

The Razer Core comes standard with 4 USB 3.0 ports for connectivity, an Ethernet port, a SATA III drive port for expansion and support for AMD’s X-Connect technology. It can also support GPUs up to 12.2 inches (length).

2. AKiTiO Thunder 3 Duo Pro Thunderbolt 3 Enclosure

Up next, we have AKiTiO’s Thunder 3 Duo Pro, the successor to their Thunder 2 series. As the names suggest, this is an improvement from the previous gen, as it has moved on from Thunderbird 2 to the new Thunderbird 3 port. The Akitio Thunder 3 uses a mere 72W PSU (external) and weighs just 7.2 lbs. The Thunder3 features a Thunderbird 3 port as well as a USB 3.1 port as well for compatibility with older laptops. Do note that the max bandwidth offered by a USB 3.1 port is just 10 Gbps, so expected results may not be achieved while making use of this port.

5. Asus ROG XG Station 2 Thunderbolt 3 External Graphics Dock

Asus has been one of the original minds behind the external GPU technology. They introduced their first eGPU – the XG Station – in 2007, which was powered by the conventional USB 2.0 port. Now, moving on with the Thunderbird 3, Asus has introduced the ROG XG Station 2. Asus’ ROG (Republic of Gamers) lineup is well known for a perfect balance between performance and a visual appeal. The XG Station 2 requires a 600W PSU and weighs 11.22 lbs, making the heaviest eGPU of the lot. Alongside 4 USB 3.0 ports, the XG Station 2 also features an additional USB 3.0 Type B port. It also has an Ethernet port as well.

6. OWC Mercury Helios 3 Thunderbolt 3 PCIe Expansion Chassis

OWC is a company that follows a minimalist approach towards its product designs. The Mercury Helios 3 is a perfect example of this statement. The “Little Black Box”, as OWC like to call it, requires a mere 90W power supply (externally) and weighs just 3.10 lbs, making it the lightest eGPU on this list. While it does not feature any extra USB expansion ports, it is the only eGPU to have a mDP (Mini DisplayPort) on it.
