About this tag
The thunderbolt 3 tag on WindowsForum.com collects discussion of Thunderbolt 3 hardware and how it performs in real Windows setups, especially external GPUs and high-speed 40Gbps connections. A recent thread compares a Thunderbolt 3 eGPU enclosure against a home-built USB4 setup using the ASM2464PD controller and Titan Ridge, testing the same AMD Radeon RX 9070 across both. The takeaway is that identical 40Gbps ratings do not guarantee identical behavior, and adapter-heavy USB4 builds can sometimes outperform a conventional Thunderbolt 3 enclosure. Expect practical, hands-on coverage of eGPU bandwidth, controller choices, and Windows compatibility.

    USB4 vs Thunderbolt 3 eGPUs: Why ASM2464PD Can Outperform Titan Ridge at 40Gbps

    External GPUs sell a simple idea: plug one cable into your laptop or mini PC and get desktop-class graphics. In practice the cable only tells part of the story. A new hands-on test from MakeUseOf shows that two eGPU setups can both be sold as "40Gbps" and still behave very differently, even with...
