1 For macOS ≥ 10.13.4: AMD RX480/580 & these are supported. Nvidia 10.13.x support can be added with purge-wrangler.
2 Flex-ATX (fATX) PSUs have a tiny 40mm high RPM cooling fan that is noisy under load. Separate external-AC PSUs are not included in product's size.
3 Meet or exceed your TB3 notebook's charger wattage for the TB3 enclosure to be a single-cable solution that includes charging. eg Macbook USB-C chargers.
4 Meet or exceed your intended video card's peak power requirements. See TechPowerUp card reviews, eg: GTX1080Ti to find this.
5 If used on a TB2/1 system via a US$49 Apple TB3-TB2 adapter, USB ports are not visible in Windows (inc Aorus' fan control). They do appear in macOS. Ref: theitsage.
6 2nd TB3 port can be DP, USB-C or daisy-chain TB3. Note: Intel often disallows a 2nd TB3 port on eGFX enclosures.
6 ports' use reduces eGPU bandwidth by up to 31.2% @10Gbps, 15.6% @5Gbps. Except for (i) Displayport devices (ii) XG Station 2 that hosts ports off a separate USB-B cable.
7 USB-based enclosure I/O ports exhibit flaky behavior under load as described, except those using a 2nd TB3 controller to host I/O ports.
7 Titan Ridge (JHL7540) allows internal routing of onboard GPU DisplayPort signals for Thunderbolt 3 monitor output. Alpine Ridge (DSL6xxx/JHL6xxx) does not.
8 Allows eGPU detection in Windows for systems reporting "external GPUs supported: no" in the Intel Thunderbolt software.
9 If require a longer TB3 cable, consider these: US$50 AKiTiO 200cm, $50 Cable Matters 100cm.

Thunderbolt 3 External GPU Enclosure Overview
External graphics card adapter or external GPU enclosure is an ever-developing solution for laptop users who need more power (than integrated graphics) for gaming, AR/VR development, AI/machine learning, and many other high demand computing tasks. Thunderbolt 3 can now be integrated to the same physical port as USB-C. Flexibility and convenience is Thunderbolt 3’s best selling point so it became the chosen standard input/output for external graphics solution. A single laptop that’s highly portable for daily use would transform into a capable gaming machine or workstation thanks to the power of an external graphics card.
External GPU Components
There are more than a dozen of Thunderbolt 3 external graphics solutions (eGFX) currently available. They share the same core components to enable external GPU for laptop with a Thunderbolt 3 connection. In this buying guide we focus on the eGPU boxes rather than the main host computer. We have also written an ultrabook laptop buying guide if you’d like to learn more about the other end of the equation.
An Intel-certified Thunderbolt 3 external GPU enclosure must have these four components:
- Thunderbolt 3 Controller – Alpine Ridge is most popular while the newer Titan Ridge also works with USB/C systems (non-eGFX use).
- USB-C Controller – Texas Instrument TPS65983 chipset has the best compatibility with host systems and regulates power delivery.
- Power Supply – Internal PSU for all-in-one eGPU dock or external power adapter for smaller footprint/quieter & cooler operation.
- Enclosure/Case – This component pays for R&D and therefore no Thunderbolt-3-mainboard-only solution is available for DIYers.
External GPU Features
External graphics card for laptop is what a sidecar is to a motorcycle; it adds capacity and utility only when needed while also remaining mobile. The convenient plug-and-play connectivity allows hot-plug and surprise removal. Besides the graphics performance boost, there are several note-worthy features some Thunderbolt 3 external graphics card enclosures provide.
- Power Delivery – Standard 15W for downstream bus-powered devices and up to 100W for upstream charging for Thunderbolt 3/USB-C laptops.
- Expansion I/O – A wide host of connectivity protocols ranging from Ethernet and USB 3.0 ports to SATA drive and Audio IN/OUT.
- Daisy-Chain – Up to six devices can connect to the host system through a single Thunderbolt 3 cable via the dual port eGPU case.
External GPU Performance
The actual performance of your laptop + external graphics card depends on many variables. Beginning with Intel 6th generation U and H processors, many laptops have Thunderbolt 3 connectivity. Appropriate pairing of processor and external graphics card would prevent CPU-bottlenecking during use. Generally speaking, an external graphics card performs at best 80% of desktop-level when gaming. External GPUs perform much better in computing tasks with many scenarios seeing very marginal loss or none at all when the application is designed to take advantage of an external graphics card.
- CPU Architecture – Quad-core CPU helps minimize performance loss. A laptop with Intel 8th gen and newer CPU is recommended.
- PCIe Lane – x4 PCIe connection over Thunderbolt 3 provides optimal bandwidth. Direct CPU attachment on H-CPU systems for best performance.
- Cooling System – Proper cooling for external GPU enclosure as well as Thunderbolt 3 connection through the system PCH & CPU.
- Thunderbolt 3 Cable – A passive .5m provides full 40Gbps bandwith and 100W PD. Active cable provides same bandwidth in longer sizes.
- Application Design – Well-optimized software and games deliver the best eGPU experience.
External GPU Setup
Windows is the most mature operating system with external graphics support. Most Thunderbolt 3 Windows systems requires no manual setup. Once connected, Windows can detect and configure appropriate drivers for the external graphics enclosure enclosure and the installed graphics card. Recent Linux distros have great support for Thunderbolt 3 as well. The main issue is driver installation and screen output configuration. Apple has been improving eGFX support in macOS. Unfortunately AMD is the only choice starting with Mojave 10.14. Boot Camp mode to run Windows on a Mac also lacks official external GPU support. At eGPU.io, we have built a community of external graphics card enthusiasts who provide creative solutions for non-officially supported configurations.
- Windows: Error 12 solutions and Boot Camp solutions to set up external graphics card on Mac computers.
- macOS: Purge-Wrangler script and automate-eGPU EFI to enable Mac external GPU through Thunderbolt 1/2, and older AMD Radeon cards/Nvidia GeForce GTX cards.
- Linux: Xorg config, easy-to-setup script, and primary display script to facilitate external graphics card configuration.

Pros
mPCIe is a common interface used to host a WLAN card which here is used to host an eGPU instead
Cons
- requires cumbersome underside system mPCIe port access
- mPCIe port can be whitelisted or deactivated by BIOS when no certified WLAN card is detected
- requires an additional USB WLAN product to then have concurrent WLAN functionality
1 Notebook mPCIe WLAN ports often do not have the USB port wired, making this a non-feature.

Pros
- a M.2 port (x1) is a common interface used to host a WLAN card in the latest notebooks
- a M.2 port (x4) is a interface used to host a fast PCIe SSD, eg; NVMe in the latest high performance notebooks
- a 32Gbps-M2 eGPU outperforms a 32Gbps-TB3 eGPU by over 20% as seen here
Cons
- use of a M.2 drive port (x4) for eGPU use is often impractical unless have a secondary drive slot/port. Spare M.2 slots are limited to only a few workstation and NUC systems.
- requires cumbersome underside system M.2 port access
- M.2 port can be whitelisted or deactivated by BIOS when no vendor certified device is detected
