The Future of Connectivity: Thunderbolt 4 vs. USB4

In an era where technology is advancing at a dizzying pace, understanding the subtleties of connectivity standards such as Thunderbolt 4 and USB4 is essential. These interfaces, while similar in many aspects, have distinctive features that differentiate them. So how do you choose the right type of connection for your devices, such as DEKO‘s versatile USB-C cable?

What is Thunderbolt 4?

Thunderbolt technology, developed by Intel and Apple, has changed the rules of the game since its introduction in 2011. Thunderbolt 4, the latest iteration, offers a maximum bidirectional throughput of 40 Gbps, which is four times faster than USB 3.2 Gen 1. It features the ability to connect as many as five Thunderbolt devices to a single PC and is compatible with older versions of Thunderbolt via a USB-C connection.

The power of Thunderbolt 4 doesn’t stop there. It supports dual 4K 60Hz monitors or a single 8K 60Hz monitor and provides robust power delivery options for various devices, including laptops. This makes cables such as DEKO USB-C, which are Thunderbolt 4 compatible, extremely versatile for both data transfer and charging.

What is USB4?

USB4, released by the USB Implementers Forum in 2019, is based on the Thunderbolt protocol and also offers speeds of up to 40 Gbps. It is backward compatible with older USB standards, but requires adapters due to the USB-C connector. Unlike Thunderbolt 4, USB4 doesn’t support dual monitors by default, but it handles single display output just fine, supporting resolutions up to 8K and even 16K.

The key is that USB4 offers variable transfer speeds and power delivery depending on the device. Some USB4 devices support speeds of up to 20 Gbps, while others can reach a maximum of 40 Gbps. This variability makes it necessary to check the specifications of products such as DEKO’s USB-C cable to make sure they meet your requirements.

Thunderbolt 4 and USB4: Similarities and Differences

At first glance, Thunderbolt 4 and USB4 appear very similar, both using USB-C and supporting speeds of 40 Gbps. However, the differences are in the details. Thunderbolt 4 always offers a minimum speed of 32 Gbps and power delivery of 15W, while USB4 capabilities may vary. Thunderbolt 4 also has an advantage in cable length, maintaining its 40 Gbps speed over a distance of 2 meters, unlike USB4, which reduces speeds to 20 Gbps on a cable longer than a meter.

Choosing between Thunderbolt 4 and USB4

When deciding between Thunderbolt 4 and USB4, consider your specific needs. If performance is a priority and cost is not an issue, Thunderbolt 4 with its higher minimum requirements and expanded features is the right choice. For those looking for affordability without compromising on quality, USB4 is the right option, especially when combined with reliable accessories such as DEKO’s USB-C cable.


In the Thunderbolt 4 versus USB4 clash, both have their advantages. Thunderbolt 4 stands out for its versatility and high performance standards, while USB4 offers flexibility and cost-effectiveness. Whatever your choice, make sure your accessories, such as DEKO’s USB-C cable, are compatible with your chosen standard to get the most out of your technology investment.
