Intel's EVP&GM accidently leaked information about Thunderbolt 5.

 

EVP&GM of Intel’s Client Computing Group, Gregory Bryant, visited a lab in Israel on Aug. 1 and posted a tweet, but clearly he did not check the picture carefully since it seems like the picture contains information about Thunderbolt 5.

 

Original Tweet (Gregory M Bryant (@gregorymbryant) August 1, 2021):

Day 1 with the @intel Israel team in the books. Great views…incredible opp to see @GetThunderbolt innovation …a validation lab tour and time with the team…can’t wait to see what tomorrow brings! pic.twitter.com/GKOddA6TNi

 

 

P.S. By the time this news is posted on LTT Forum, the original post has already modified, and the most important picture was removed.

On the poster, it says 80G PHY Technology, which means the new Thunderbolt 5 will have a max. speed of 80Gbps, which is twice of Thunderbolt 4's speed. Thunderbolt 5 will keep using Type-C and downwards compatible. Also, on the poster, it says "… will be based on a novel PAM-3 modulation technology", which means in order to support a higher bandwidth, the Thunderbolt 5 will use PAM-3 as its protocol. On the final line the poster mentions the N6 test chip, which supports this new PHY technology seems to be able to demonstrate a promising result. On the screen it might be a showcase for showing Thunderbolt 5's speed, probably on a PC running the N6 chip (probably a TSMC chip).

 

Overall, in the world where Thunderbolt 4 is not universal yet, Thunderbolt 5 is already on the way.

PAM-3

In case you're like me and you're wondering what nonsense PAM-3 is, here's a chart:
