Thunderbolt 2 & Thunderbolt 3

post #1 of 3
Thread Starter 
Hi,

I've got some motherboards that support both TH 2 & TH 3 and the cards that are compatible with the motherboards, however, I'd like some more information from the people that may know.

Certain boards such as

Asus Z97-AR
Asus Sabertooth Z97 mk 2
AsRock X99 Extreme 4

Are all compatible with Asus TH 2 EX card which supports 20 GB/S

Other boards such as

Asus Sabertooth X99
Asus X99 Deluxe 2

support the TH 3 EX card 20 GB/S

Queries are,
Is the speed of TH contained within a chip on the TH card? - 20 gb/s vs 40 gb/s
And are there differences within the PCB of the motherboards that support TH2 vs TH3

Would the TH2 cards work on motherboards that support TH3? - Or the other way around? - Or are there inherent differences within the PCB of the motherboards?

It doesn't matter too much but it would be nice to know how inter-changeable the technology is within the supported products.

There has been a great deal of confusion and lack of clarity at times with this.

An example is another boards I've got

MSI Z97 Gaming 3 - I bought this for the PCI slots and by accident found on the MSI drivers page that there is a thunderbolt driver but no mention of thunderbolt being supported on the MSI product page for this board.

I did later find this board on Intel thunderbolt supported products but not on the MSI website itself.

There is no mention of a supported thunderbolt pci-e card for this motherboard but I may try a TH card on this board, after all it is Intel technology isn't it?

I actually don't know the answer for sure.

I would guess that they would all be some what cross compatible.

Thunderbolt is just a connection type that uses your PCIe lanes directly. I am sure there is some sort of standard that the motherboard or add on card has to comply with, but as long as you have available PCIe lanes, you should be good.

Worth a shot maybe?

Yeah just some queries

I think the motherboards are "Intel" certified for TH2 or TH3 - though I maybe wrong but maybe not. I think also that the same generation TH are cross compatible on other motherboards - eg - MSI motherboard with TH2 certification will probably work with Asus TH2 card - though I've not tried this.

I don't think I'd try at TH2 card on a TH3 certified motherboard, maybe a bit pointless

FWIW - I think the future TH will be TH3 over the new USB 3.1 C type connector for 40 GB/S - The current USB 3.1 type C is good for 10 GB/S but is not yet TH3 40 GB/S on most boards.

Any TH I've got is via the add in cards - Asus TH2 & TH3 so I'm covered for TH!!!
