@mymantiz_john, have you done any testing in-house on the 30 series? I'm a little concerned with this review using Saturn Pro II and 3080: https://egpu.io/forums/postid/86798/

Seems the performance is much better on a Chroma ( https://egpu.io/forums/postid/86633/) but there certainly could be other factors at play...

@bmagnien, The builds you linked have not only different eGPU enclosures but also different CPUs. The host computer is more crucial in performance outcome than the eGPU enclosure. If an TB3 eGPU enclosure can provide 22Gbps throughput, it should not be any more limiting than other TB3 options on the market. U-CPU hosts usually have no dGPU and the PCH shares CPU cooling system while H-CPU hosts have high power dGPU and likely no cooling on PCH.

@itsage, thank you for the thorough description. I wasn’t aware of a lot of that. It helps a lot, thanks again!

@bmagnien, I wish Intel had done a better job sharing these information so that the general public understands this technology. I have plans to do PCIe 4.0 testing through direct internal Desktop slot (Gigabyte B550 Vision D), Thunderbolt 3 enclosure, and maybe M.2 adapter as well...whenever I can get an RTX 3000 series card that is.

@itsage, would you agree with what this guy writes: https://evanmccann.net/macbook-pro-thunderbolt-3-port-technical-details ?

I honestly find his wording a bit hard to follow, and not knowing the tech feature specs that he's referencing very well makes it more complicated as well. But he basically sums it up by writing: "What this means is that eGPUs and other high end Thunderbolt attached devices are going to perform better on the 15-inch and 16-inch."

So is he saying a 9980HK (I assume this is a H-CPU?) MBP 16 will perform better with an eGPU than a U-CPU ? Sorry if those are dumb questions

Hopefully last question: I tried to better educate myself by reading through your super helpful guide on the topic here: https://egpu.io/best-laptops-external-gpu/

May I ask if the 16'' MBP i9 9980 HK w/ 5600m dGPU, 4xTB3 ports, would have made the cut to be included in your 'best laptop' list at the bottom of that guide? Or is it missing any of those 4 requirements that you'd be looking for? Maybe it didn't make the cut because the price caused it to be less of a good value when paired with the additional costs of an eGPU?

Thank you!

@bmagnien, Mac computers are in a different class when it comes to Thunderbolt connection regarding their system design. The 2019 16-in MacBook Pro is one of the best eGPU hosts. All 4 TB3 ports have direct CPU attachment rather than going through the PCH like most H-CPU Windows systems. My eGPU laptop article is outdated and needs to be updated with the latest laptops. It also focused on U-CPU ultrabooks that doesn't have a dGPU. To learn more about Macs and their Thunderbolt 3 ports, this is the better article - https://egpu.io/boot-camp-egpu-setup-guide/#egfx

I have tested my wife's 2019 16-in MacBook Pro with the RTX 2080 Ti Gaming Box [build link]. The RTX 3080 + Mantiz Saturn Pro setup should perform better than RTX 2080 Ti eGPU, especially at 4K gaming. While the Nvidia eGPU doesn't work in macOS, all expansion I/O including Power Delivery from the Mantiz Saturn Pro should work in macOS just fine.

After I contacted Mantiz's customer service staff, they quickly sent me a new FSP power supply by SF Express. And they also sent me pictures which showing how to dismantling the PSU. The after-sales work is very good. Thank you John.

But after I replaced the PSU, I found that the new power supply still has that kind of noise, but the sound is a little lower. After contacting Mantiz after sales, they decided to send me a new power supply. But as a Ph.D. sutdent, I can't spend too much time on this matter. Every time I replace the power supply, I need to stop the computer from working, and this work will occupy me all night. I think it's better to get it done tonight.

After several considerations, I decided to disassemble the old power supply and directly replace the internal 12 cm x 12 cm fan. I replaced the original HK-FAN fan with the Noctua NOCTUA NF-A12x15 fan, and then threaded the fan's 4pin cable out of the power output hole and connected it to the Saturn Pro's motherboard.

Then, the world was completely quiet. Although I lost the warranty, this is the best option for me.

It is worth noting that the current power supply fan can not automatically stop, so there is a little bit noise in normal use.

Thank you John. I still think that Mantiz is one of the most recommended eGPUs in the market, whether in terms of product performance, cost performance, or after-sales reliability.

I will finish my desktop PC in a few months. I only need one motherboard now. ASUS X299 Deluxe II and Gigabyte X299X Aorus master are the target motherboards.

@itsage, I have a question regarding the amount of pcie lanes supported by the host laptop. I have a dell xps 13 9360 which has a TB3 port with 2x pcie lanes, would this be enough to use the saturn pro - gpu, charging, ssd, ethernet and all - or could this cause throttling?

I hope I used all the technical jargon right, I'm new to the world of eGPU's Smile

Hi,

 

   Received my saturn pro v2 few days ago, and put my old 1080ti in it.

   Pretty cool performance, less drop than I though compared to my desktop. The massive amount of connectivity is really cool.

   There is 1 problem than I can't resolve, I want to shut off the eGPU when my laptop (hp spectre 13" 2020) goes to sleeping mode. I dunno why the eGPU continue to run when the laptop is off. I tried on the bios to disable the USB charging option, but did'nt changed anything.

   Does anyone has a solution ?

 

Thanks

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

So I have my Saturn Pro II and it's pretty great. I wish eGPU enclosures would give you somewhere to keep the PCIe slot blanks, and it'd be nice if the cables coming out of the PSU were shorter, but that's really just nitpicking. This thing feels really solidly built, it's whisper-quiet at idle, and if I swap the chassis fan out for a Noctua of some kind then it'll be totally inaudible.

But all that said, I've run into what appears to be a weird compatibility issue. I've tried it on a few systems - For reference, I have an EVGA GTX 1070 SC installed, but I don't think that's relevant in this case.

  • Wife's Lenovo T480, Windows 10 Pro 2004 (build 19041.508) - works great
  • Intel NUC10i5FNK, Ubuntu 20.04 Desktop - also works great
  • MacBook Pro Mid 2019, macOS Catalina 10.15.6 - also works (I swapped the card over to an RX Vega 64 for this test)
  • My Lenovo P52, Windows 10 Pro 2004 (build 19041.508, same as the T480). Does not work.
    When I connect the Saturn, I get the "Thunderbolt device functionality might be limited" message & the enclosure doesn't power on at all 🙁

I've been using the P52 with a Galax SNPR eGPU enclosure for months now, and that works just fine.

I've done all the usual tricks - BIOS updates, reinstalling TB3 drivers and software, everything short of reinstalling Windows fresh (which I'm honestly not too far away from trying anyway). I thought it might be that the P52 doesn't support charging from Type-C, but the NUC doesn't either, and that works just fine.

Kind of at a loss for what to do next, short of just reinstalling Windows. There doesn't seem to be a lot of debug/log information available for TB3 devices on Windows 🙁

Lenovo P52 - i7-8750H, 4x16GB, 2x1TB NVMe, Quadro P1000 (Optimus... ugh)
MacBook Pro Mid-2019 - i9-9980H, 32GB, 1TB, Radeon Pro Vega 20
