This DESTROYS Thunderbolt - Oculink Makes eGPU Feel Like Desktop!

I don't anticipate anyone using Oculink on devices that would have PCIe3.0 but know that bandwidth would only be slightly better than Thunderbolt 3/4 in that arena.

ALSO, older cards will see diminishing returns as well between the two. So something to be mindful of.

So tempted to add an oculink port to my laptop now... I might even have space for a very clean install. What's the maximum cable length and would an internal cable to a port cause issues?

what about buying a desktop instead.....

If I was to use Nvidia Tesla P40 in a EGPU setup using Thunderbolt 3/4 connectors will that work for my laptop if I was using it for stable diffusion and video encoding?

You should share this with the Framework community, for the FW16.

But how many devices have a oculink port? It seems to rare now as of 2023. If that's only present on already gaming devices...

It would be nice if GPD offered OcuLink upgrade kit for original Max2 - after all it would slot into m2 2230 slot at the bottom.

Hmm, never got eGPUs before but I have a winmax 2 and the ONLY reason I turn on my desktop PC at this point is for VR. I don't have the new one with a Oculink Port but I don't use the second SSD anyway so heck, I might as well and then just sell my desktop PC. All my desktop PC is for anyway is to hold my 3090 for VR, my winmax 2 plays everything else.

Fair to say the GPD win4 7840u plus the G1 is gonna be pretty close to desktop performance?

I made an oculink egpu based on yours and ETA prime’s design. It works wonderfully for my wm2, you have saved me from spending way more money for much more inferior thunderbolt egpus

Could this be used in a micro form factor PC?

can someone dump the links so i dont have to join yet another discord server?

Usb4v2 and thunderbolt 5 are coming with more bandwidth than occulink! And you will have power delivery, ethernet, usb, and displayport tunelled via thunderbolt/usb4. Occulink is a good solution for eGPUs but thunderbolt will proliferate because tunnels the protocols that consumers need/care about. Perhaps occulink should consider doing the same.

Can I use this in my 6800h laptop which doesn't have an oculink port with some adapter?

So the winmax 2 has a second nvme slot?

If it would be a Intel
Platform we would have pcie5 that would be even more awesome.. pcie6 is around the corner .. imagine how massive it will be then!

I feel like this connector will be dead in 2 years time. Given how bad USB 4 is right now, it will eventually improve thankfully.

Any link for a oculink to tb 3 cable ? I can't find nowhere ? Please help !

PCI card digonse card
Hecate

I feel like this is the eSATA version of egpus ... great idea and better performance but no one wants it. Then along comes the next version of USB which eclipses it and no one remembers it in a year. USB4 V2 does 80gb bidi (vs 40gb on usb4) and thunderbolt 5 is capable of doing 120gb in ansync mode where it uses 3 40gb channels to send data and 1 to receive it... which is what most eGPUS will do (vs 40gb on tb3/4). So by next year this will be a "forgotten tech" video.

please do more videos like this

So is occulink the same deal as connecting your egpu through an m.2 nvme socket which uses pcie 4x 3.0 or 4.0 ?

Thunderbolt 5 coming next year should close the gap with twice the bandwidth of TB3/TB4/USB4

I got a server where I wanted too connect GPUs in an external case. It has tons of oculink support on the mainboard for 24nvme drives at full X4, was searching for this for long. It's pcie so I don't get why this wasn't on the market yet.

what Thunderbolt egpu dock this in the video the with the atx power supply can you link thanks in advance

"Wink wink" ... "oh I have something in my eye!"......................................... uh huh... thanks for letting us know that the GPD Win Mini and the GPD eGPU have oculink onboard...

will this work on mac s?

Does the WIN 4 have Oculink?

does any one know if a rtx 3090 usb type c port can be used for power and data on gpd win max 2's usb c for up to a total of 8 lanes? i like to see if its even possible and if so by how much? or does just run like [kvm] design

I really need help. I just brought the Gigabyte gaming box 3080 for the Win max 2 but it just won't connect to thunderbolt 3 cable nor usb4 cable. I've tried reinstalling the usb 4 drives, the thunderbolt 3 drives, ive tried installing the AMD auto scan adreneline addition, resetting the WIn max 2 BIOS... nothing is working... all i can think of is reinstalling windows 11, or downgrading to windows 10. Some people have said this works for them.

How do you get the egpu to work for yours?

Is it possible with steamdeck through m.2

Over the last few years there have been 2 or 3 laptops with a native oculink connector, which served PCIe 3.0x8. USB4/Thunderbolt 4 is simply too slow for modern eGPUs. OCuLink-2 can do PCIe 4.0x8, but no hardware maker seems interested in offering this for a gaming laptop. Why can't consumers get nice stuff? It's always reserved for servers…

wink wink GPD :D

Personally this is useless, I use the internal screen with egpu 60fps at 800p in 99% of the games on win max 1 with a 6 feet cable.. I dont know why anyone would want to use an oculink+ an external screen when you could simply game stream at 4k on it without wires. Why buy a handheld and not use the screen built in and carry mini egpu if you travel around the world.

Could you use this on the Gpd win 4 using another drive to boot windows? Not that I would always keep it like that but just as a possibility

now i wanna see oculink on a aya neo or steamdeck style device.

My server has a couple of those on it. Epyc CPUs have so many PCIe lanes I think they just figured why not?

could you put the card in an enclosure? are there any you'd recommend if so? also, which m.2 adapter did you use?

What are the, if any, disadvantages of disabling REBAR? This is my first time hearing of it and, to me, it seems like something that should never be enabled by default. Why does it exist?

This is really interesting. Is this Oculink 2 with 16gbps per lane?

This is my setup at home, too. Literally my dream computer. Win max 2 with occulink & 3090. Portable power, desktop power. No compromises.

I wish we didn't have to use the Discord for all this stuff, its impossible to navigate :(

Now the real question... can this be done to the GPD Win4? I somehow doubt that it has an M.2 slot that is convenient enough to get to, but I would be more than willing to pay someone to mod the shell and add a port for this. The Win4 and my current 3090 as an eGPU is EXACTLY what I have planned as a spare/mobile setup to my current Dr. Zaber Sentry 2.0 build that I have as a main PC.

Don't care

Been donw that road before with proprietary or not universal connections.
Sticking with USB-C/thunderbolt connections for their ubiquity and besides
USB-C 4.2 or whatever is purported to support 80Gbs data transfer speed and with p.d 3. Whatever will support over 100w charging.

Thunderbolt 5 is supposedly going to have 160Gbs data transfer speed.

I will inly jump on to a new connection IF it is a new Universal port/connection and only then when it is the clear replacement of USB-C and is adopted on to all devices that have used USB-C

I mean why don't they just double up and add 2 thunderbolt cables? :P

how can i buy the M2 to oculink adapter designed for the GPD winmax 2 and the cable ?

Does this work in the steam deck?

Thank you for an amazing video! Do you think such type of an eGPU enclosure could work with GPD Win4?

Love the idea, and I'm glad it's getting more feasible, but it's not for me. I'm just not that big on an eGPU - I have a nice desktop for when I want to be stationary, and I really only use my GPD WM2 when I'm away from it.

I do appreciate having thunderbolt, but not for an egpu - I just occasionally connect my WM2 to the dock that's normally reserved for my work macbook - then I get an awesome display and a full keyboard and mouse.

Thank you for your work! Great video. Please make video on detailed comparison 8x lanes oculink vs thunderbolt vs desktop 🙏
