The biggest thing I didn’t see at CES: Thunderbolt 5. Insiders explain why

Where are all the Thunderbolt 5 laptops? Dock makers say they won't arrive until 8K hardware becomes a thing.

Interesting reading! He noted 2 factors in the way of larger scale adoption are the lack of Intel chipsets with integrated Thunderbolt 5 inside and 'stalled' transition to 8K content - a lack of 8K broadcast means a lack of 8K displays means hardware capable of rendering 8K content isn't as valuable - a 'chicken and egg' scenario.

" Abdul Ismail, the chief technical officer of the USB Implementor’s Forum (and a senior principal engineer for Intel), said his estimate was widespread USB 80Gbps / Thunderbolt 5 adoption was not until 2027 or so."

Jeff Lukanc, senior director of product marketing of video interfaces at Synaptics was noted to state:

"“What is happening is refresh rate.”

From what his business customers have told him, Lukanc said, “I’ve been told to plan on 165Hz for the next five years” with 4K displays."

I shared some prize pieces to convey trends here, but the original article is worth a read. From what I understand, Thunderbolt 4 is covering most people's needs, so it sounds like with TB 5 we should anticipate an incoming trickle, not a wave. For a couple of years, anyway.

In another thread I brought up the issue of beyond 4K video content (such as 8K) and whether and when it might be offered by streaming services such as Netflix, and what kind of bandwidth burden that would put on the Internet infrastructure in the U.S. The feedback I got was basically too much pain for too little gain, don't hold your breath.

Just thought this article was too good/relevant not to share. Glad Apple went to TB5 for M4Pro and Max chips across their late 2024 Mac line, but the PC market isn't likely to do so anytime soon.

Also, he didn't focus on a desire for high speed external SSDs such as one could use to avoid very high vendor costs of internal SSD storage. Hmmm...

From the point of view of a Mac user, the biggest advantage that TB5 could solve is the sharing of the bandwidth of the single cable connection to the Mac.

TB4's 40Gbps to a dock/hub means that you could be sharing that ~3000MB/s between 4 or 5 devices - 5k displays, NVMe SSDs, maybe 10Gbps ethernet etc.

Upgrading the dock to TB5 bandwidth means this bottleneck is considerably relieved.
This is even more important with the higher power MacBook Pros, as single cable connectivity is an advantage in allowing the MBP's power to be easily available.

I agree that that's a compelling case on the Mac side.

Which begs the question...why is it presumably not nearly so compelling on the PC side? If 8K is practically dead on arrival (so far), why isn't there clamoring for TB5 in new Windows notebooks and TB5 docks?
 
My guess is that the overwhelming number of computer users simply don't yet NEED the speed that tbolt5 offers.

A small number might need it... and be willing to pay the freight.
But the rest...?
