ARMing PCs with powerful USB ports
While Windows on ARM PCs may not traditionally feature Thunderbolt ports due to Intel’s ownership of the standard, there’s an interesting development that could bridge the gap for users who rely on Thunderbolt’s robust capabilities. Many upcoming Windows on ARM PCs are expected to include USB4 ports, which have the potential to be compatible with Thunderbolt 3, 4, and possibly even the forthcoming Thunderbolt 5 accessories, depending on the USB4 port’s specifications.
Thunderbolt has become an essential feature for professionals and creatives who need to expand their PC’s functionality with additional displays, storage, and graphical power. And while Thunderbolt has predominantly been a feature of Intel-powered PCs, the introduction of USB4 could change the landscape significantly. USB4 ports, which are built on the open-source Thunderbolt 3 standard, offer similar capabilities and bandwidth, allowing users to connect their existing Thunderbolt docks and hubs.
However, not all USB4 ports are created equal. There are variations within the USB4 specification, and understanding the capabilities of each is critical for ensuring compatibility with Thunderbolt devices. For instance, to match the 40GBps bidirectional bandwidth of Thunderbolt 4, a USB4 port must be specifically labeled with a 40GBps designation. As for the higher bandwidth of Thunderbolt 5, which boasts 80GBps bidirectional and 120GBps unidirectional speeds, the USB4 port must be marked with an 80GBps label. Although, it’s worth noting that Thunderbolt 5 and the corresponding USB4 2.0 are still in their infancy and not widely available.
For those considering the switch to an ARM-based PC, particularly models powered by Qualcomm’s Snapdragon X series SoCs, the inclusion of USB4 ports could be a game-changer. Not only could these devices offer a sleeker, lighter form factor with extended battery life, but they may also maintain the power users have come to expect from traditional Intel and AMD PCs. Compatibility with Thunderbolt, while not guaranteed, is a possibility that could sway many potential buyers.
As the landscape evolves, it will be fascinating to watch how Windows on ARM PCs adapt and potentially embrace the Thunderbolt ecosystem through USB4. For the latest updates on the best Windows on ARM PCs that don’t compromise on Thunderbolt compatibility, tech enthusiasts should stay tuned to the most reputable sources for news and reviews.
