USB keeps changing their own standard every 2 years why bother learning it.

[-] 4lan@lemmy.world 21 points 2 years ago

Pshh, speak for yourself. I'm ready for USB 3.2 gen 5 pro ultra max

[-] sugar_in_your_tea@sh.itjust.works 13 points 2 years ago

But will that be better or worse than USB 3.3 gen 2 extra super speed?

[-] 2xar@lemmy.world 8 points 2 years ago

Both, of course.

[-] mightyfoolish@lemmy.world 3 points 2 years ago

Will USB 3 get an update now USB4 is out?

[-] sugar_in_your_tea@sh.itjust.works 5 points 2 years ago

Eh, USB4 is basically what USB 3.3 would've been, but with fresh branding. I expect it to have the same naming issues after a few updates...

[-] mightyfoolish@lemmy.world 2 points 2 years ago

Wasn't USB4 based on Thunderbolt 3?

[-] sugar_in_your_tea@sh.itjust.works 2 points 2 years ago

Sort of? It borrows a lot of the high speed protocol bits from Thunderbolt 3, but I think it does DP a little differently (at least it supports different DP standards than TB3). So it's closely related, but not necessarily the same thing.

Was that the first one that had M Bison as a playable character?

[-] dual_sport_dork@lemmy.world 5 points 2 years ago

We're not calling it that anymore. It's been rebranded to "SuperDuper Speed USB ]|[" now. Note that this is a different standard than the previous "SuperDuper Speed USB 3," and under no circumstances should you call it "SuperDuper Speed USB 3.0," because there was never any such spec and pedantic nerds will climb up your nose in the comments if you ever utter it.

I mean, they update the standard to add new things. Is that bad?

[-] Turbonics@lemmy.sdf.org 3 points 2 years ago

They also change existing terms for no good reason.

[-] s_s@lemm.ee 0 points 2 years ago* (last edited 2 years ago)

The don't.

But give me an example of what you're talking about. I'll explain.

[-] Turbonics@lemmy.sdf.org 1 points 2 years ago* (last edited 2 years ago)

USB3.2 gen 2, USB3.2 Gen2x2

[-] s_s@lemm.ee -1 points 2 years ago* (last edited 2 years ago)

The consumer facing names for those transmission specs are and have always been:

  • SuperSpeed 10 Gbps

  • SuperSpeed 20 Gbps

Unless you're designing your own circuits you don't need to worry about signaling rates (ie "Gen") or lane configuration (Z×Y).
