AKiTiO has quietly begun to sell its Thunderbolt 3 to 10 GbE network adapter, which it first demonstrated at Computex 2017. The device is based on a 10 GbE solution from Tehuti Networks and is compatible with both Macs and Windows PCs. Priced at just under $300, AKiTiO is selling the adapter directly as well as through Amazon.

As described back in June, the AKiTiO Thunder3 10G (T3NA-T3LNITY-AKT) network adapter supports five speeds, including 10GBase-T as well as NBase-T, allowing it to work not only with corporate 10 GbE networks, but also with upcoming 2.5GBase-T and 5GBase-T networks primarily aimed at small businesses and consumers, as well as existing 1 GbE and 100 M networks. The device itself is a relatively small rugged box made of aluminum for better heat dissipation and featuring rubber pads on its sides for further protection.

The adapter is bus-powered, it only has one 10 GBase-T port, a Thunderbolt 3 header, as well as an opening for a security lock. Unlike many other TB3 devices, this one does not have another TB3 connector to daisy chain it with other TB3 appliances, perhaps to reduce development and BOM costs (more on this later), or address security concerns of certain clients. Theoretically, it should be possible to plug the Thunder 10G network adapter at the end of a Thunderbolt 3 daisy chain after a display and a DAS, but AKiTiO does explicitly list this as supported.

The AKiTiO Thunder3 10G (T3NA-T3LNITY-AKT) is based on Tehuti Networks’ TN9710x-TB3 reference design for Thunderbolt 3 to 10GBase-T/NBase-T network adapters. This reference design is intended to minimize the number of chips and components required: it carries Tehuti’s own TN4010 MAC, Marvell’s Alaska X 88X3310P 10 GbE transceiver, Intel’s DSL6340 Thunderbolt 3 controller (which is why daisy chaining is not supported), Texas Instruments’ TPS65983 USB Type-C and Power Delivery (PD) controller, as well as an essential set of power and other ICs (integrated circuits). AKiTiO already uses Tehuti’s designs for its Thunder2 10G network adapter as well as its 5-Speed 10G/NBASE-T PCIe network card, so the decision to go with this partner was logical. Apart from developing chips and reference designs, Tehuti provides unified drivers for them and having one driver for all three products greatly simplifies their support. Speaking of drivers, the Thunder3 10G is compatible with macOS 10.12.5 and above, Windows 7 and Windows 10.

AKiTiO’s Thunder3 10G is now available directly from the company as well as from Amazon for $279.99, which is below MSRP of most Intel-based 10GbE add-on cards. Considering the fact that the latter are generally aimed at servers and high-end workstations (and therefore come with appropriate features and software stack), this is not really surprising. In the meantime, it is noteworthy that the Thunder3 10G costs $120 less than the Thunder2 10G ($399.99), a clear indicator that 10 GbE hardware in general is getting more affordable.

    I suppose this is your only solution for laptops, but since Intel NICs were compared with, the Aquantia NICs should also be mentioned for $99.

    Furthermore, the price of Intel 10g NICs have come way down, especially OEM versions--which are what most consumers will buy--rather than the Intel retail branded cards. Another big factor that needs to be taking into account is most you see are *dual* port, so you are getting twice for the money in that case.

    Intel Corp X540T2 Converged Network Adapt T2 (single port) = $140.00

    Intel Corp X540T2 Converged Network Adapt T2 (*dual port* 10Gigabit) = $247.99
    Pretty good, no?

    edit: single port model is X540T1 Reply

    Except that the T1 model is the same price as the T2 model everywhere I look. I don't really get the T1 model at all when it is somewhere more expensive than the T2 model.

    Even your Amazon link proves the T2 as being the least expensive.

    A box of matches is small and the above NIC isn't small. As it's 'only' a nic the price really needs to hit $99 before people take notice. Even then it's too expensive.

    Will the mainstream ever stop milking people or maybe, just maybe, take a chance and move straight to the next level. 10Gbe should be standard by now. Same for 4k screens.

    Can anybody come with a guess of why they are not making a 10G USB 3.1 model? That should be a no-brainer. I would gladly pay for it as a SFFPC user.

    Or just integrate the damn AQC-107 in most mainstream and upwards boards. Come on! Lets get the 10G revolution going!!! :-D
