We purchased a "USB 5.0" cable, even though we knew that the USB 5.0 standard doesn't officially exist. Curious about what this cable offered, we wanted to know if it had any additional features compared to the latest official standard, USB4 2.0. USB4 2.0, validated in 2022 by the USB Implementers Forum (USB-IF), is the current highest version of the Universal Serial Bus standard. It allows data transfer speeds up to 80 Gb/s and can support asymmetric transfer rates of up to 120 Gb/s in one direction and 40 Gb/s in the other, with a total combined bandwidth of 160 Gb/s. Despite the absence of any new USB versions since 2022, some cables and manufacturers have started labeling products as "USB 5.0." This term is not recognized by the USB-IF or any official standard. It seems to be used by some original equipment manufacturers (OEMs) and third-party cable producers to suggest an upgrade or improvement. However, the exact meaning of "USB 5.0" remains unclear and unverified by the official USB consortium. In our testing, we wanted to determine if these "USB 5.0" cables actually offer higher data transfer rates or support increased power delivery compared to USB4 2.0. While the official standard continues to evolve with USB4 2.0, the market has seen unofficial variations and claims. Understanding the true capabilities of these cables requires further investigation and verification by independent testing or certification. For now, the USB 5.0 label appears to be a marketing term rather than an official standard. Consumers should be cautious and look for certified USB4 2.0 products when seeking the highest performance and compatibility. Until more information emerges from the industry or the USB-IF, the true potential and purpose of "USB 5.0" remain uncertain.
