Introduction and Product Tour

eGPUs (external GPU enclosures) promise the best of both worlds, allowing you to carry a thin-and-light laptop while you're on the road and then turn it into a gaming behemoth when you're at your desk. $499 (GPU not included), the Razer Core V2 can turn Thunderbolt 3-enabled laptops into bonafide gaming PCs, but competitors are significantly cheaper.

Razer’s minimalist aesthetic and premium build quality are the Core V2’s highlights. The case is built out of solid aluminum with a matte, anodized finish. The aluminum is quite thick and hefty, and is wrapped into a single rectangular piece with soft corners. The left side features a cutout and a mesh grille, allowing your GPU fans to suck cool air. The opposite side features an engraving of Razer's company logo.

The top of the Core V2 features a wide cutout for additional airflow. The top grille consists of two layers; the top layer features thick, slotted vents, while the bottom layer has a honeycomb vent cut from a thinner piece of metal. The front of the Core V2 features a solid metal shroud with a slotted design complimenting the top vent. The bottom of the slotted front shroud has small openings to allow the Core V2’s RGB lighting to peer through. Finally, the bottom of the Core V2 features two large rubber feet to keep the chassis stable.


Accessing the interior GPU dock is as simple as can be. The rear folding handle acts as a locking mechanism; pulling the handle out releases the lock, allowing you to pull the GPU dock out. The handle is made of solid metal, and every bit as hefty as the rest of the Core V2. However, the finish isn’t as refined as the anodized aluminum exterior.

The first time you release the Core V2’s GPU dock, you’ll be presented with a thick, GPU-sized foam pad featuring a GPU sizing guide with simple installation instructions. For reference, your graphics card must be 11.81 x 5.71 x 1.69 inches at most, including the amount of space needed for the 8-pin power cords. Removing the foam pad reveals a small motherboard, which contains the PCIe x16 slot.

The bulk of the Core V2’s internal space is taken up by the 500W Enhance Electronics power supply. The rear of the power supply has an AC power cord leading to the rear I/O ports. Two 8-pin PCIe power cords connect from the power supply to the motherboard, providing power to the Core V2 and the connected GPU. Additionally, whichever laptop you pair with the Core V2 will receive power via Thunderbolt 3.

The Razer Core V2’s rear I/O ports consist of a Type-C port supporting Thunderbolt 3, four USB 3.0 ports, one gigabit Ethernet port, and an AC power input. Additional video ports will be dependent on your graphics card.

The bottom of the interior dock features a slotted vent similar to the top and front of the Core V2’s exterior chassis. The vent contains three fans to keep the motherboard cool.

To the left of the motherboard you’ll find an aluminum shield shield secured by a hand screw; you’ll need to remove this before installing your GPU.

Two additional 8-pin PCIe power cables extend from the right of the motherboard and wrap upward. There are two velcro strips near the end of the power supply to keep the PCIe cables stable.

If you want to remove your GPU, you’ll have to flip the GPU release lock, which can be accessed from behind the power supply.


The Razer Core V2 is compatible with all Razer laptops out of the box, but it will support any Thunderbolt 3-enabled laptop with external graphics support. Furthermore, your laptop must have all of the latest Thunderbolt 3 drivers, up-to-date graphics drivers, and Windows 10. If your laptop has a discrete graphics card, you’ll need to download the GPU Switcher software from Razer’s website to allow the dock to work seamlessly.

The Core V2 has two RGB LED lighting strips: one beneath the front shroud and one next to the GPU. If you have Razer Synapse installed on your laptop, you can adjust the Core V2’s lighting effects. Effects include spectrum cycling, breathing, wave, and static light. If you have Razer peripherals such as a Chroma V2 keyboard or Naga Epic mouse, the lighting can be synced via Razer Chroma. Attaching a Chroma supported Razer laptop such as the Blade or black Blade Stealth will sync the RGB keyboard with Core V2's lighting.

    thunderbolt 3.0 and its limited 5GB/s max bandwidth isn't a problem? even more if the dmi 3.0 limits the chipset speed to 4GB/s. i mean, desktop pcs provides 16GB/s with a 16x pci-e 3.0. if you have a good laptop cpu, i think they should develop a port like an external pci-e with enought bandwidth that is controled directly by the cpu.

    One could build a mini-itx system for less than that price.

    Not a mention of thermals, noise levels, stability, experience with peripherals attached, etc. The main difference between the V1 and V2 was the addition of the 2nd TB3 controller daisy chained off the first to give the GPU top priority in the chain. Testing with the stealth was also a poor choice, you should have at least gotten a Razer laptop with a 45w CPU, they have several options you could have used - this was not an apples to apples comparison with the other laptops because of that. You also should probably spend a paragraph talking about how PCIe is plumbed off of the CPU vs. off the PCH (and therefore over the DMI) in many laptops and how that can impact performance with an eGPU. Really there are a LOT of things you could have done better in this review. I was glad you mentioned the internal vs external display performance difference though as I feel this is an important point when considering such a solution.

    I tested one of these with my Alienware 15 R3 (I know not "officially" supported but kind of worked...) and for me I had a lot of issues when I connected peripherals into the USB ports on the Core vs directly into my laptop USB. Also the provided TB3 cable was SHORT but I suppose a longer one can be bought and used unlike the Dell TB docks. Compared to my Alienware Graphics Amplifier the performance difference was very noticeable for my GTX 1080 Ti due to the added overhead of Thunderbolt.
