Best Razer eGPU

Razer Core V2

  • Chroma lighting
  • Easy to use
  • Good GPU compatibility
  • Expensive
  • No GPU included
  • Limited laptop compatibility

If you are familiar with other Razer products (phones and laptops), then you must be familiar with their signature look. The Core V2 maintains the same beautifully, anodized black aluminium body that you will see on all Razer laptops and the previous eGPU generation. Regarding the previous Core, it is identical to the V2, though the latter has some significant changes regarding performance. You will still see the company’s logo on the right side of the eGPU and a large, metallic grille on the left side. It has vents along the bottom, front, and the top to help in managing temperature increases within the unit. Dimensions are 11.8×5.7×1.7 inches, which is slightly larger than the previous generation. Top it off, the V2 features chroma lighting.

The Razer Core V2 does not come with a graphics card out of the box. It does pack a massive 500W power supply, and has Razers standard high build quality.

Best Value

Gigabyte Aorus Gaming Box

  • GPU included
  • Powers the laptop
  • Very portable
  • Limited GPU upgrades
  • Flakey USB
  • Coil whine

The Aorus Gaming Box has similar features to those of the Razer Core. It is also an external GPU enclosure, which works with laptops through a Thunderbolt 3 connection.

This unit is compact and relies on Gigabyte’s GTX 1070 GPU and a 450W power supply. Being thin limits upgradeability of the Aorus Gaming Box, but it allows it to remain small and portable. It weighs just five pounds, making it easy to carry it around in your backpack, and it doesn’t take up so much space in a desk setup.

Best Cheap eGPU

Akitio Node

  • Cheap
  • Easy to use
  • Macbook Pro support
  • Short TB3 cable
  • Not portable
  • Loud fan

Akitio Node is one of the eGPU enclosures that support a wide variety of laptops as long as they rock the Thunderbolt 3 port. The manufacturer behind this product stresses reliability and practicality more than anything else. However, the most outstanding feature of the Akitio Node is that it is the largest of all the enclosures mentioned in this roundup. The size is reminiscent of that of an actual computer. For this reason, it is the least portable of all the mentioned products.

An affordable but massive eGPU, that works on the MacBook pro.

Considerations Before Buying an eGPU

Being a new product in the market, few people are familiar with eGPU enclosures. For this reason, you may not know exactly what to look for when the need to purchase one of these devices arises. Here are some of the things to consider before handing over your money to the seller.


Ensuring that the GPUs fit into an enclosure is the essential aspect of this process. Most enclosures will fit the biggest of graphics cards without any problems, but as technology continues to advance, more compact models should start appearing. Check on the amount of space an enclosure will take up and where you’ll keep it. Ask yourself whether what you find is portable. Go for the lighter models if you are always on the move. Always carry it in a padded container to reduce the risk of damage.

Technical Considerations

Check out the compatibility of ports and whether they have good speeds. You will need a port with higher
bandwidth for the best user experience. Thunderbolt 3 is the most common port for this kind of use. The problem is that only high-end newer laptops have these ports. Do not buy an eGPU before confirming whether your laptop supports Thunderbolt 3.

Another vital thing to check is the list of compatible computers for specific enclosures. Ensure that your laptop is in this list and double-check so that you don’t end up with the wrong product. Also, check whether the power rating can support the graphics cards that you intend to work with.


If you are the kind of person who always goes for the latest tech or gadgets, the price might not be a problem for you. However, if you are just out looking for a high end gaming PC, you’d want to build one rather than investing in a high-end laptop plus a graphics card, and an eGPU enclosure. If you want the best performance out of your eGPU, you’d want to connect it to a different display other than the laptop’s, such as a monitor or a TV. That means forking out some extra cash for a display. Remember, it all boils down to your preferences.

The Bottom Line

Laptops do a great job in providing most desktop computing capabilities with portability. However, using laptops comes with the disadvantage of losing the ability to upgrade most internal components. Since not everyone can afford to purchase a new laptop every few years, getting an eGPU seems to be a reliable approach towards keeping up with the seemingly rapid advancements in computer processing. The external graphics card enclosures mentioned above are future proof. They will allow you to upgrade your GPU without ever having to worry about them not being compatible with your laptop. From the detailed descriptions of each eGPU, you should be able to make the right purchasing decision that meets your needs.
