Thunderbolt to dock and than daisy chain to egpu is a bad idea. An egpu needs a dedicated connection for max banwidth

That would be true, but eGPU docks often include a few USB ports and possibly Ethernet to make them advertise as docks. To⌠mixed results.
I think I found an obscure one with dual cables specifically to give the GPU maximum bandwidth. Itâs just not quite a mainstream market, so attracts limited investment. IMO.
It is a product that suits the Framework particularly well though, so it keeps coming up here. Really cool seeing some of whatâs going on, too.
For the record i dont own a framework, but I use a 7940hs @ 90w(realistically 75w, stock cooler wont sustain 90w for more than 45-60 seconds, and i lack time to modify the stock heatsink or make one or use a aio on the vaporchamber opposite side of the heatsink fin stack) with a 6900xt paired over oculink 4i 4.0 (pcie x4) running a 4k 120hz tv, and i find more often than not my 6900xt bottlenecks my 7940hs in the odd arrangement of old/new games that i regular.
Its basically a 7700 non x equivalent, with a cache difference if i recall correctly. Im also using poor timing 5600mhz ram currently.
I see no reason why someone cant design a breakout to oculink from the two gpu connectors, the pinout is available. There are already x8 oculink gpu docks out there, I own one, high quality cables are lacking though.
Its up to the userbaseâs determination.
Well, I am down for the FW16 for all those reasons. Only competition I wanted to wait for was the XPS16, and yes, it is extremely beautiful and much smaller with same screen size, but damn, I am not paying 2000+ Euros to be stuck with a RTX4070 with 8gb of VRAM and 60Ws in 2024. Sorry, that train has left.
So I hope to use oculink for a true desktop performance asap with the FW16 ;).
I think an Occulink x8 bay to replace the discrete GPU bay would be ideal for docking and getting the most out of any GPU you could attach. PCIE4 at 8X (16GBps) blows away USB4/TB3 40Gbps(5GBps) which isnât actually 40Gbps because of overhead and encapsulation (more like 32Gbps) etc. Remember Gbps != GBps, theyâre very different! 8bits = 1Byte.
The real issue is firmware and max Occulink cable length to ensure PCIE4 is usable and doesnât fallback to PCIE3 (still faster at 8GBps, but somewhat a waste). Even PCIE riser cables were having issues with PCIE4 so you should expect Occulink 8x to struggle to get PCIE4 speeds without proper shielding etc. But at PCIE4 x8 you should get over 90% of any external GPU you can connect.

Completely agree, here is a good overview of current progress on the issue of signal stability, still mixed in the communityâŚ
Luckily handtalker, creator of onedock (v2) is apparently in touch with Lenovo for dedicated oculink ports on notebooks also for Western customers - but likely to late to reach before FW16 actually becomes an available product.
My money is on someone in the community building an adaptor (which thankfully is ongoing).
Its an expansion bay. Framework could totally create the expansion bay and sell it later this year. They didnât release the NIC expansion card until later either, and I ordered it with my preorder of the FW16. Its simple enough to go directly from PCIE to Occulink with a redriver. Iâd buy one the moment they released it.

Same here. But Framework CEO signalled they will âprobably notâ build it themselves. So my money is on a rescue from the community. 
If anyone builds it, I will buy it on day one.

There is already someone who designing a drop in PCB that will fit in the default empty expansion bay. So you theoretically wouldnât need Framework to design it, they designed the bay and shell, and the community can design and sell the drop in PCB.

Yes, Josh here in the thread has already designed a solution and is in testing phase. I bought it on day one. I personally trust his solution will be apt at ensuring safe oculink x4 and x8 speeds (I bought both). My current EGPU is One Dock v2 (arrived after weeks of hassle with EU customs finally) which is already I think an advanced solution for signal integrity. So thatâs my plan for oculink x4 speeds for now (all I need for my trusted RTX 3090 for now).

Do you have a link to buy it? Looking to run my 7900 xtx off my framework 16 for 4k, I have the 7940hs as well in mine so i wouldnt imagine that being a bottleneck.

Thanks for a quick response! Are you able to use paypal for payment? I wouldnt mind paying a little more if theres a fee for it.
Such a kick-ass community. Every single one of you is awesome for trying to solve this problem

Wow so will this allow me to run an oculink gpu on the framework laptop screen? Or do I have to run it on an external monitor?
There is a DP In port for using the internal screen
How does that work? I have to disassemble the laptop and redirect it?
The expansion bay system already has an Display In for the dGPU. The Oculink just routes that to an external port.
You know there already is a really long thread explaining all this.
Please link me the thread. I just found this thread yesterday while searching.
