What, you mean like firewire vs usb? Like thunderbolt vs usb3 or 10Ge or
6Gb eSATA or any other low-cost high speed bus? I love the marketing sham
of the thunderbolt cable with chips inside of it. Because supposedly that's
necessary in order to get 10Gbit across the link... ;-) Like a Cat 6
cable, or an eSATA cable for $6. ;-)
Yes, there is a reason for the existence of these things. Apple makes more
money if consumers believe there is a reason to buy them... So it doesn't
matter if there is any actual benefit... It's marketing. Just like so many
of their other products.
FWIW, I just looked it up, and HDMI can transport 10Gbit just like
thunderbolt. There's some sort of 8/10 encoding overhead, I suppose that
must be error detection, so the actual payload is 8Gbit. This includes (I
forget now) ~34 Mbit for audio or something like that. And supports
resolutions up to 4k x 2k
Oh, here's the perfect example. This is a 10ft cable that supports 4k x 2k,
and 10Gbit. Goes for $4.97. You can clearly see that Apple would not make
any money selling something that competes with this.
