![]() Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. ![]() However, note that next-generation GPUs are around the corner, like the Nvidia 'Ada' RTX 40-series and AMD's RDNA3, so keep that in mind. After 18 months of extreme prices, most cards can now be found online for only 20–30% over MSRP, sometimes less. Thankfully, the supply and GPU prices on Nvidia's RTX 30-series cards as well as AMD's RX 6000 cards continues to improve. For specific recommendations, see our best graphics cards list of the current options, as well as the GPU Benchmarks Hierarchy to see how today's cards compare to older cards that you might be looking to upgrade and replace. There's so much to consider, from the type of monitor you're using (for recommendations, see our Best Gaming Monitors page) to the size of your PC case to the game settings you plan to play at.īelow are the things you need to keep in mind when shopping for your next GPU. Unfortunately, the process of figuring out how to buy a GPU can be intimidating. The graphics card is even more important than the CPU. Enclosure/Case – This component pays for R&D and therefore no Thunderbolt-3-mainboard-only solution is available for DIYers.Getting the best graphics card is key if you're looking to buy the best gaming PC or looking to build a PC on your own.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 & 4 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 & 4’s best selling point so it became the chosen standard input/output for external graphics solution. Thunderbolt 3 & 4 can now be integrated to the same physical port as USB-C. Thunderbolt 3 & 4 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. Here ◄ eGPU Port Bandwidth Reference Table for CUDA-Z or AIDA64 measured bandwidth 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.ĩ USB4 systems have stricter USB4-certified cable requirements such as: Anker 515 1m USB4 cable, Spigen 0.8m USB4 cable, Orico 2m active TB3, SKY USB4 4k 240w cable, Ultunite USB4 cable 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 ( JHL7xxx) as found in EXP GDC TH3P4G3, AKiTiO Node Titan, and others gives ~10% more PCIe bandwidth than older Alpine Ridge (DSL6xxx/JSL6xxx) though has a negligible affect on game FPS as discussed.ħ Titan Ridge ( JHL7540) allows internal routing of onboard GPU DisplayPort signals for Thunderbolt 3 monitor output.
