Intel Thunderbolt 5 Specifications Leaked

After months of rumours, Intel has finally unveiled its 10th generation of Thunderbolt technology. The name of the new platform is the Thunderbolt V, with the board code TBV. It will be based on the same Intel Skylake architecture as the previous generation. Intel’s Thunderbolt V is a faster version of the Thunderbolt, and is designed to take full advantage of the bandwidth of the new PCIe 4.0 bus. Thunderbolt V supports the same PCIe lanes as PCIe 3.0, giving it a theoretical bandwidth of 32 GB/s per Thunderbolt V port. However, the motherboard will probably be limited to up to 16 GB/s by its Thunderbolt controller.

In a surprising move, Intel has quietly released its Thunderbolt 5 specifications. The performance improvements and technical details of the new port make the next generation of Thunderbolt a strong contender for the top hardware prize, even if it’s not replacing the standard USB-C port.

Intel has now officially started the Thunderbolt 5 development process. It has already acquired an OEM partner and the roadmap for the next generation of Thunderbolt devices has been leaked. Now, we all know that the first Intel Thunderbolt 5 device will be the XPS 15 9560. The new device will not be a gaming laptop, but will be aimed at the professional market. It will feature an Intel Core i7-8705G processor, 16GB of DDR4, and a 256GB SSD. With a 12GB GPU, it will pack all the power you need to run the latest games.

The capabilities of Intel’s upcoming Thunderbolt 5 technology have leaked courtesy of one of the company’s own executives, Gregory Bryant, who recently visited one of Intel’s R&D facilities in Israel and accidentally shared photos on social media revealing some information that wasn’t meant to be public.

Intel’s Thunderbolt 5 will have amazing speeds of up to 80 Gbps, according to a banner visible in one of Bryant’s photos, which is twice as fast as the current Thunderbolt 4 standard. This is due in major part to PAM-3 modulation technology, a new way of sending zeros and ones that allows for this greater data transmission rate.

Intel had indicated earlier this year that it was looking on methods to double Thunderbolt 4’s already outstanding 40 GBps bandwidth, but Bryant’s error seems to confirm that Thunderbolt 5 would far outperform its predecessor in terms of theoretical speeds.

The first day with the @intel Israel team has come to an end. Fantastic vistas… It’s an amazing opportunity to witness @GetThunderbolt innovate… a tour of the validation lab and time with the staff… I’m excited to see what tomorrow has in store! pic.twitter.com/GKOddA6TNi

Intel’s aim with Thunderbolt will be to increase bandwidth, power, and utility, but it seems that sticking to the USB-C standard will be a critical element of making the technology usable for customers who can utilize regular USB-C connections. Currently, Intel’s TB4 is a superset that includes USB4, so we may see another scenario where TB5 is ready to be a superset of USB5, although USB standards seem to be rolling out slower than TB standards at the moment.
