Thunderbolt 4 is now widely available across Apple devices and computers, newer PC's and as an add-on to existing PC's.

So what is Thunderbolt 4?

Thunderbolt 4 is the latest generation of Intel's premium connectivity. It is fully compatible with Thunderbolt 3 and USB4. It is backwardly compatible with all USB-C versions.

With an increase in the speed of hardware and ever increasing demands of professionals, gamers, and users of processing intensive software, there has been a corresponding significantly higher data performance required to maintain peak performance.

Thunderbolt 4 is that major update catering for that extra hardware and software demand.

Evolving from Intel and Apple's existing Thunderbolt 3 specification, Thunderbolt 4 complements and builds on the existing USB-C, 3.2 and 2.0 architectures. The result is that you can plug a USB-C cable into a Thunderbolt 4 port and it will operate normally as USB-C. The socket remains the same as that which has been used for several recent versions of USB, most popularly known as USB-C.

However, Thunderbolt raises the maximum bandwidth to 40Gbps and, as with Thunderbolt 3, enables multiple simultaneous data and display protocols. Thunderbolt 4 can dynamically share a single high-speed link with multiple end devices, so that the priority task or process is allocated the bulk of bandwidth.

Intel's USB Type-C connector has has become an almost default interface for modern computers and devices, so the introduction of Thunderbolt 4 allows for that backward compatibility whilst at the same time allowing users to buy new Thunderbolt hardware without being penalised by different connectors or incompatible protocols.

Like Apple's famous tagline - "it just works".

The result is that there is 100% compatibility with existing USB-C, USB 3.2, USB 2.0, USB4 and Thunderbolt 3 devices.  Thunderbolt 4 can support 3 speeds: 10Gbps, 20Gbps, and 40Gbps.

The giant step forward is that Thunderbolt allows for dual lane operation and up to 40 Gbps operation over 40 Gbps certified Thunderbolt cables, such as HomeKit Australia's 100w 5A Thunderbolt cable that includes an e-Marker verification chip within its design.

Thunderbolt 4 also supports the USB PD charging standard. Put simply, M1 MacBooks and MacBook Airs, a future iPhone, existing Android smartphones and other devices can charge significantly faster over Thunderbolt.

The good news for PC fans is that Intel began the integration in 2019 of Thunderbolt into their CPUs as of their tenth generation Core processors.
