When talking about Thunderbolt 5 I wish MacRumors would put the necessary asterisk that the 120 Gbps transfer speed is a special use case meant for displays. Thunderbolt 5 is 80/80 bidirectionally (40 Gbps across 4 lanes with two lanes uplink and two lanes downlink). For certain display modes it can switch to 120/40 up/down speeds, converting the third lane from a downlink to an uplink. This is not intended for data transfer.
 
I am pretty sure I read that Apple’s 1m Thunderbolt 4 Cables will support Thunderbolt 5. The passive Thunderbolt 4 and Thunderbolt 5 cables are the same. It is only the active Thunderbolt 4 cables that are not compatible with Thunderbolt 5.
Unfortunately the 1M cable (passive) has a built-in chip.
This probably will used to identify the cable and limit the speed, otherwise it should be identical.

As usual, Apple is charging ridiculous prices for cables.

No thanks, I'll do what I always do and ONLY buy 3rd party.

You've got to be nuts to pay Apple price for a cable.

To be fair there aren't many choices for Thunderbolt 5 cables at the minute. Cable Matters have one (which is pretty ugly) for £32 on Amazon, which works out at roughly $42. For the same price you've also got the random named Chinese companies on Amazon like SEEZOW and MOTREW - I think for $20 more i'd probably buy the Apple one.
 
Priced at $69, the new 1 meter Thunderbolt 5 Pro Cable supports Thunderbolt 5 data transfers at the maximum speed...
Apple: put the numeral “5” on the cable connector, just below the lightning bolt. It lets people know this is a Thunderbolt 5 cable, versus 4 or 3. Other manufacturers do this.
But that will add an extra $0.05 to Apple's cost... and Apple will have to price the cable at $79 instead of $69 to recoup that cost.

You think that's expensive? Try nVLink...

This is not for connecting your keyboard to the Mac!
It's for tying two (or four, or many more) mini's (or other macs) together to create a low-cost training powerhouse...
 
Ah yes from well renowned brand Cable Matters :rolleyes:, I'm sure that will absolutely be in spec. (just to be clear, it won't).
The cable linked to in the post you replied to is in spec, unless you know more than Intel; it is certified, and this is easy to look up: https://www.thunderbolttechnology.n..._value_many_to_one=All&field_company_nid=2832
Now look up the prices from reputable brands and not rando Chinese that'll cut corners in the spec.
I don't think Cable Matters is an disreputable brand (Chinese, possibly; I can't find any information on that other than a warehouse in the US; Apple's cables are also likely manufactured elsewhere).
 
I just bought the Caldigit Thunderbolt Station 4 Pro (that's the Apple one, somehow way cheaper than the Caldigit non-pro one) to hook it up to my MB M2 Max. Love it. Guess I'd still love it when upgrading my MB to the M4 Max. Wouldn't know any peripheral needing 120 Gbit/s at this moment.

What can you actually connect with thunderbolt 5? There is no tb5 ssd as far as I know?

Specs:
"USB 4 data transfer at up to 40Gb/s"

Not full functionality: USB 4 is available at 80Gbps.

Also:
No longer active ones yet, at 3m or even 1.8m.

Wonder if Corning will offer optical ones at 10m+ length. I have a TB3 optical of their's that works flawlessly, so here's hoping sooner rather than later.

Ya, we will have to see.

I think I read this in Intel’s own Thunderbolt 5 press release, and since all these cables use Intel chips, hopefully they know what they are talking about.
