I don’t think you should besmirch the good name of FireWire with such comparisons.

Say what you will that gpu wire never sold out like his old man.

that gpu wire is a hoser

My 2006 era poorly interlaced mini dvi videos beg to differ.
Nothing else was fast enough to transfer them to my computer.

Idk. Seemed pretty useful before usb 2.0 came out.

FireWire was so good. RIP to a real one

It was great in design but too few peripherals made use of it. The lack of input devices (e.g. mice, joystick, keyboards) meant that for most people it was far less useful than USB.
Still pretty cool that you could (and still can) use it for networking in a pinch, not to mention the decades worth of video devices that will happily dump their contents to DV video as long as you have a FireWire port. Finding a VCR with DV output is one of the best ways to digitize old VHS recordings if you can't set up VHS-decode.

I remember reading that one reason firewire was so great was that every device had a controller chip or something like that, whereas USB used the system processor for a lot of stuff.
So the cheaper option won the mainstream market over the better option. Now where have I heard that before other than all of the times?
Bluewing1
Eh, it's less about which is the "better choice" and more about "how good does good enough need to be". With a dash of the 80/20 rule.

Oh I'm an engineer that works on physical products (embedded software) and you will get zero disagreement from me there, lol. That is the case even with expensive stuff that's sold to other businesses rather than cheap consumer tech.
And the way I meant "better" was more like "superior specs / technically better." I mean, as far as "good enough" and "meeting user needs at lowest cost > exceeding needs at higher cost" you cannot argue with the success of USB. It has succeeded beyond the scope of its own name.

50 amps through those skinny wires? I’m no engineer but eve I can see that’s going to get hot.

Shoulda used fibre. Glass is naturally insulating.
SatansMaggotyCumFart2
I think it would only be five amps.
jjagaimo10
Tdp for a 5090 is 575W / 12V = 47.92A
At 12 pins (2x6) thats ~8A per pin (47.92 / 6)
SeductiveTortoise8
Yes, but if I remember correctly the issue is that they don't make sure to limit the current per pin, but to let electricity decide which path to choose. So for some it might be 2A and for others 16A for example.
glibg10b4
It depends on the board. Some boards have balancing circuitry, some board can only detect overcurrent on individual wires, and some can only detect total overcurrent (through the shunt)
SeductiveTortoise2
I'll take the one that balances correctly please.
jjagaimo2
It is a combination of multiple issues. This is one of them
Bussing the connection on the card side means no balancing of currents between pins, like you said. Older cards dont do it per pin but do divide it into several input rails which are individually monitored for current / voltage differences and will disable the card if it exceeds a certain threshold.
Usually cards would use larger pins on the older 8 pin pcie power cables, which can handle more current and will make better contact in addition to being easier to seat fully without jamming and keep retained.
Additionally they tend to use multiple connectors (e.g. 2x8 pin connectors = 8 pins for +12V), with lower power allowed per pin for more headroom. This means higher current capability and less potential for failures
For example, a standard 9070xt with a 304W TDP may use 2x8 pin connectors. Larger pins, more pins and lower tdp, with current balancing/monitoring on board. It comes out to 3A per pin at full load when the pins are rated for something like 9A.

So, uh, money-grubbing in manufcturing?
SeductiveTortoise2
There's always money in the banana plug factory.

Your calculation is correct, but just in case anyone not versed in electric circuits is reading: It's 47.92/6 not 47.92/12 because the other 6 pins are ground (the "return" path for the electricity, it's a circuit after all).
SatansMaggotyCumFart3
So definitely not 50a.

I had one burn up on a 1070
CompactFlax8
PC PSU output 3, 5, and 12V
I_am_10_squirrels2
50 amps at 12 volts would be 600 watts. The GeForce RTX 5090 draws 575 watts at full load. That is some FireWire.
SatansMaggotyCumFart-1
boonhet6
Are you going to be running 120 volts into your graphics card? That would be brave
SatansMaggotyCumFart1
Probably better with 120 volts versus 1200.
boonhet4
I think most of us have 12, but between 120 and 1200 I'd choose the latter because it would be more fun

That's certainly no XT60 on the end!

Is that the gpu wire that keeps catching on fire?
