Over the past week AKiTiO has formally introduced its new external graphics enclosure using a Thunderbolt 3 connection. As with other external graphics enclosures, the AKiTiO Node allows a user to easily upgrade the graphics sub-system of notebook, AIO or SFF PCs that have a Thunderbolt 3 port by using a discrete graphics card. One of the key elements to eGFX is price and look, and AKiTiO has placed the Node at $299, but itcan fit graphics cards with massive coolers.

Enthusiasts started to experiment with external graphics over Thunderbolt 2 interface several years ago after multiple attempts of companies like ATI/AMD, ASUS and some others to develop commercial external GPU technologies had failed. Back in 2014, plugging a video card to a MacBook Pro using Thunderbolt 2 was costly: users had to buy a chassis for up to $1000 (there were cheaper methods, but they did not look solid), a PSU and a graphics board. The homebrew method worked, but had a number of limitations when it came to bandwidth, hot-plugging (more importantly, unplugging), driver support and some others, not to mention the aesthetics of such eGFX setups. Given the trend towards miniaturization of mobile and desktop PCs, the idea of external graphics was far too alluring to skip, which is why Intel decided to support it with its Thunderbolt 3 technology introduced in 2014. While technically TB3 is PCIe 3.0 x4 over a cable, to properly enable operation of external GPUs, Intel and its allies had to ensure support of eGFX hardware though operating systems, GPU drivers, firmware and so on. Earlier this year all pieces of the puzzle finally came together and the first “official” TB3 eGFX chassis were introduced by Razer and PowerColor.

While both Razer Core and PowerColor Devil Box do the job and even feature a couple of extras, they are rather expensive as they add more than just GPU features - $499 and $379, respectively. This week, AKiTiO, which has been offering external Thunderbolt enclosures for years, introduced its eGFX box that costs $299.99.

The AKiTiO Node is a 42.8 × 14.5 × 22.7 cm (16.85 × 5.71 × 8.94 inches) box made of stainless steel that is compatible with a variety of double-wide full-length/full-height AMD and NVIDIA graphics cards (see the list here). The Node comes with an integrated 400 W SFX PSU (which means that it can be upgraded) as well as one 120 mm fan. As for dimensions, the Node seems to be a little more spacious inside than its rivals, which is good for cooling and compatibility with custom video cards (such as those from ASUS or EVGA). Despite this, GPUs with hybrid cooling (integrated liquid cooling) are not supported, such as AMD Radeon R9 Fury X.

Unlike competing products, the AKiTiO Node is a pure external GPU box and nothing more. It does not have extra USB 3.0 ports (to connect a VR headset, for example), a GbE controller nor a SATA connector. This naturally cuts down its costs and allows Akito to sell the eGFX enclosure at $299 price-point, but additional USB ports will be greatly missed by owners of ultra-thin laptops as well as SFF PCs.

AKiTiO plans to start selling the Node (NODE-T3IA-AKTU) in December.

    Why would Apple have to create the drivers? NVIDIA already does this, and you can buy external GPU-boxes for Macs. They're called Bizon Box and work with PCs too. We have two at work, and planning to buy more, but this seems better. Bizon Box is built using older versions of Akitio boxes and they are very expensive. Would rather cut the middle man out and get them straight from Akitio. Reply

    AMD cards should work. Reply

    Días antes del lanzamiento oficial de Clash Royale Update, una fuga comenzó a propagarse en línea. Se reveló cuatro cartas que posiblemente se incluirán en las características de la próxima versión.

    Soon PCIe will take over the world as the universal local interconnect. Reply

    Considering what the Power Color Devil Box offers, for only $80 more, the price for this should probably be cut a little. I'd expect at least a $100 retail price difference for those features. Reply

    Indeed the PowerColor can serve nicely just as an expansion dock as well. Although I do like the dedicated bandwidth and dedicated purpose of the AKiTiO box. Reply

    What I don't get is why AMD and Nvidia aren't at the forefront of making affordable Thunderboxes. It would expand the market for dedicated graphics cards. Reply

    And reduce the market for mobile GPU's that have higher margins than the external GPUs? Reply
  • WorldWithoutMadness - Monday, November 14, 2016 - link

    That's if they're playing it wrong. If they're playing it right, they can get 2 GPU sales (mobile GPU + external GPU). This also serves as upgrade option. It's not like majority of people throw away their laptop every a year or two. Reply

    "Works best/only with our mobile GPU line for reasons that are maybe technical" there you go. :) Reply
