@Mehenn:

The side ventilation grill was done with a cnc machine,
the openings in backplate, inner backplate and PCI bracket with drill an file.

The 9pin connector snaps into the opening with plastic brackets.
Its a panel mount connector.

BIG UPDATE: With mod we can fit ZOTAC GeForce® GTX 1080 Mini 8GB (211mm x 125mm) and ZOTAC GeForce GTX 1070 Mini 8GB (210mm x 122mm) in the Aktitio length if we remove the fan and the front side piece half removed. (Top side part) Only need to remove half of the side. But the Akitio front will be there and we will have a closed Akitio with 1070 and 1080 inside - the best video cards on the market right now! Both Video Cards are too tall but with new Cover or Cut the Akitio Cover we can have the best mini eGPU with the best power inside!

Hello everyone!

 

First of all, thanks for the fantastic briefing and info on which cards do the job on the Akitio Thunder 2. I currently use a Macbook Pro 2015 (with AMD integrated GPU) with my Akitio Thunder 2 + Dell 220W DA2 PSU +  GALAX GEFORCE GTX 970 GAMER OC 4GB DDR5 256-bit+ Windows 10 and it works just fine, never giving me issues.

Since newer games are coming out, I am thinking about making the jump to a GTX 1070 (since I believe a 1060 the performance jump is not that high compare to what I have at the moment), so I am really interested into knowing more on cutting the upper part of the Akitio case. Do any of you guys know how could I cut the metal part? Which tools would I need? I am not particularly skilful on these tasks. Also, even though it is mentioned before, I am not sure my PSU could handle the GTX 1070 mini.

 

Thanks again for spreading the eGPU world!

@Piqudo Gigabyte GeForce® GTX 1070 Mini ITX OC 8G (Length 169mm / Height=131) and ZOTAC GeForce GTX 1070 Mini 8GB (Length 210mm / Height=122mm) both will work wit DA2 220W external PSU that you have! You will need only 6pin to 8 pin cable and to cutting the upper part of the Akitio case, for ZOTAC you will need to remove the fan and also to cut the metal where is the fan!

If you don't know how to cut metal parts, it's better to ask a friend that can do it for you!

About 970 vs. 1060, right now for FULL HD gaming - with 1060 you can play all games on external display all to the max + MSAA and with 1680x1050 on your internal display again all to the max + MSAA! 

1060 with 6GB is around 30% better than your 970 4GB GPU!

1070 and 1080 are just better if you UP the resolution. So my advice is - EVGA 1060 6GB you can see my mod with Thunder2 and DA2 here - https://egpu.io/forums/builds/2012-15-mbpr-gt650m-gtx106010gbps-tb1-akitio-thunder2-win10-enjoy/

I just joined this site. Got the Akitio Thunder 3 and 1050 GTX ti SC 4GB in the mail for my HP Spectre x360 2016. Will post some pictures and video if everything works out well. Question:

I saw people reporting performance drop from what they see on desktop benchmarks vs over Thunderbolt 3. Does the penalty increase with the graphics card performance? Meaning for example 1050 is a 10% drop but 1070 is 20% due to the bandwidth limitations etc. of the T3? Meaning you would get less of a boost in performance when upgrading in the future when the 1080 mini's come out?

@bookatechie - Yes this is true, after tons of results i see online, the better video card you get the more performance drop you will have, for example:

  • 1050 - 10-15% performance drop (eGPU vs. Desktop)
  • 1060 - 15-20% performance drop (eGPU vs. Desktop)
  • 1070 - 20-25% performance drop (eGPU vs. Desktop)
  • 1080 - 30-40% performance drop (eGPU vs. Desktop)

 

Its not only about Thunderbolt1, Thunderbolt2 or Thunderbolt3 - Better Thunderbolt just allow you to up the resolution and to use your Internal Display again with better resolution IMO!

The penalty does not increase with the video card. It increases with frame rate. Since a more powerful video card will, in general, generate more FPS, it will see a greater performance reduction, but if you were to run a higher resolution, or with higher settings, then the loss will not increase. To elaborate: If a 1060 gets 70 FPS at certain settings, and a 1080 gets 70 FPS at a higher resolution (or with higher settings), then your loss will be similar for both. At the same resolution and settings, the 1080 will get a bigger loss due to it driving more FPS. That is why you should be aiming for an eGPU that will drive your selected resolution at 60-70fps, and not aim for 100+ fps in your selected games and resolution, as you start hitting diminishing returns.

Yes it is increase with better video card because with better video card you get more FPS 😉

But this does not mean that 1060 will show better results in games vs. 1070 and 1080 of course Smile
