AOOSTAR Unveils XG76 and XG76 XT eGPUs with OCuLink, USB4 and Relatively Affordable Pricing
The prominent Chinese brand AOOSTAR has unveiled its XG lineup of RDNA 3-based eGPUs. Consisting of the XG76 and the XG76 XT, the eGPUs are powered by the AMD Radeon RX 7600M with 28 CUs and the desktop-class RX 7600 XT with 32 CUs respectively, both with a 150 W TDP. These GPUs are plenty performant, and are likely to offer respectable 1080p gaming performance.
Similar to offerings from competitors such as GPD and Ayaneo, the XG lineup features dock functionality as well. Both the variants sport USB4 connectivity with up to 100 W of power delivery. Display output is taken care of by the dual DisplayPort 2.0 ports, and a single HDMI 2.1 port. The system also rocks OCuLink support, allowing for a significantly lower performance hit when compared to Thunderbolt 4 or USB4.
As for pricing and availability, both the XG76 and the XG76 XT are available for pre-order. The XG76 is priced at $499, while the XG76 XT commands a hefty $619 price tag. Unlike certain other offerings in the eGPU segment, there is no option for an M.2 slot for storage expansion, which might be a tad disappointing for some. An external 330 W PSU is also required.

1) why do these GPU docks skimp on connectivity? I can get a Thinkpad dock with six type A ports, two type C, two display port, an HDMI, multi gig Ethernet, and dedicated audio jack. Why can I not have that connectivity and a GPU?
2) why is it always the 7600? That GPU is weak sauce. If I'm paying this much, where's the 4090 mobile or 6850m/7900m docks?
Docks like this try and skimp on connectivity because of lack of bandwidth. You need more than OCuLink or USB4 can provide.
Adding ports means needing more bandwidth.
7600 is for 2 reasons: 1. Because everyone decided its THE GPU to use in these for some reason. And 2. A more powerful GPU will be bottlenecked by the lack of bandwidth.
When Thunderbolt 5/ USB4 2.0 becomes more common we will see more options
The real answer is, 7600M XT was the only GPU introduced as the mobile one for a long long time - so indie companies had to deal with it and build their designs around that particular chip. Only much later on we were told that 7900M will actually happen (in fact, did it?). Non-mobile chips have never been considered really for the much higher idle clocks/temps/power draw - however that's also disputable. I'm running egpu on 7600XT (non-m, an external GPU using normal PCIex slot card) and I'm seeing ~15W (well, plus all the overhead of the dock, extra egpu chip, efficiency losses in the whole chain etc ~30W) while GDP G1had final power draw around 15W - while ALSO being a 100W laptop charger.
