Enclosure/Case – This component pays for R&D and therefore no Thunderbolt-3-mainboard-only solution is available for DIYers.Įxternal graphics card for laptop is what a sidecar is to a motorcycle it adds capacity and utility only when needed while also remaining mobile.Power Supply – Internal PSU for all-in-one eGPU dock or external power adapter for smaller footprint/quieter & cooler operation.USB-C Controller – Texas Instrument TPS65983 chipset has the best compatibility with host systems and regulates power delivery.Thunderbolt 3 Controller – Alpine Ridge is most popular while the newer Titan Ridge also works with USB/C systems (non-eGFX use).We have also written an ultrabook laptop buying guide if you’d like to learn more about the other end of the equation.Īn Intel-certified Thunderbolt 3 external GPU enclosure must have these four components:
In this buying guide we focus on the eGPU boxes rather than the main host computer. They share the same core components to enable external GPU for laptop with a Thunderbolt 3 connection. There are more than a dozen of Thunderbolt 3 external graphics solutions (eGFX) currently available.

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. Flexibility and convenience is Thunderbolt 3’s best selling point so it became the chosen standard input/output for external graphics solution. Thunderbolt 3 can now be integrated to the same physical port as USB-C. Thunderbolt 3 External GPU Enclosure OverviewĮxternal 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.

Alpine Ridge (DSL6xxx/JHL6xxx) does not.Ĩ Allows eGPU detection in Windows for systems reporting "external GPUs supported: no" in the Intel Thunderbolt software.ĩ If require a longer TB3 cable, consider these: US$50 AKiTiO 200cm, $50 Cable Matters 100cm.
Note: Intel often disallows a 2nd TB3 port on eGFX enclosures.Ħ ports' use reduces eGPU bandwidth by up to 31.2% 15.6% Except for (i) Displayport devices (ii) XG Station 2 that hosts ports off a separate USB-B cable.ħ 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.ħ Titan Ridge ( JHL7540) allows internal routing of onboard GPU DisplayPort signals for Thunderbolt 3 monitor output. Ref: theitsage.Ħ 2nd TB3 port can be DP, USB-C or daisy-chain TB3. See TechPowerUp card reviews, eg: GTX1080Ti to find this.ĥ 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). eg Macbook USB-C chargers.Ĥ Meet or exceed your intended video card's peak power requirements. Separate external-AC PSUs are not included in product's size.ģ Meet or exceed your TB3 notebook's charger wattage for the TB3 enclosure to be a single-cable solution that includes charging.
Nvidia 10.13.x support can be added with purge-wrangler.Ģ Flex-ATX ( fATX) PSUs have a tiny 40mm high RPM cooling fan that is noisy under load.
