However, what Intel is working on is “PAM-3”, which is a technology where the data line can carry either a -1, a 0, or a +1. A scheme that allows two bits to be transferred is called PAM-4 (Pulse Amplitude Modulation). Traditional NRZ encoding allows for a 0 or a 1 to be transmitted (that is, a single bit). This is all about how the 0 and 1s are transmitted. Getting more technical, the PHY is based on “a novel PAM-3 modulation technology”. Intel has previously mentioned using “80G PHY Technology”, which refers to the physical layer. Storage data transfer is typically bidirectional in nature.

Thunderbolt 4 was more about setting common standards than speed increases. ![]() This is an especially significant increase, given that Thunderbolt 4 didn’t even nudge up bandwidth when it succeeded Thunderbolt 3 in 2020. Thunderbolt 5’s new speeds are therefore up to three times that of Thunderbolt 4. Intel has stated that this next-generation Thunderbolt will deliver 80Gbps (gigabits per second) of bi-directional bandwidth (40Gbps + 40Gbps) and, when across three lanes at 40Gbps each, would enable up to 120Gbps for the best video-intensive display experience. ![]()
