12" Asus Transformer 3 Pro T303UA + [email protected] (AKiTiO Thunder3) + Win10 [icttrack]

Recommended Posts

Hello guys,

 

I am just a newbie who likes the concept of eGPU. The guide here https://www.techinferno.com/index.php?/forums/topic/7947-the-basic-egpu-hardware-guide-for-macs/ really helped me a lot about eGPU fundamentals and how to do it properly. After reading it and other guides, I was able to set up my own with the new Akitio Thunder3 PCIe box. Here are the details:

System: Transformer 3 Pro

CPU Intel Core i5 6200U

8GB RAM

256GB SSD

 

The card I use is ZOTAC GTX 1060 6GB Mini. I chose this because it fits nicely into the box and I am not really a serious gamer

 

My method to provide enough power is to use a PSU with paper clip trick and I cut the wires from CPU connector 2x4pin to connect to a barrel plug
To avoid soldering, i bought a barrel plug with screws. However, this one doesn't fit into Akitio's socket, so I had to buy a barrel adapter to make it work. See the pictures below

Afterwards, driver installation is flawless. The box will power the card only when thunderbolt cable is connected to my tablet. I can reconnect at any time (hot plug) and system is able to recognize the card almost instantly.

 

For benchmarking purpose, I used the existing game Batman Arkham Origins that my tablet struggles to play. Details are as follows:

 

All other graphics settings are at highest values
1920x1080, internal display: 50FPS
1920x1080, external display: 55FPS
1920x1440, internal display: 45FPS
2560x1440, external display: 40-45FPS (cannot remember the exact value)

 

To compare thunderbolt performance with the desktop one, I plugged the card into my friend's desktop computer (Intel Core i7 6700K, 16GB RAM). 
Under 1920x1080, the difference is huge with the card being able to perform at 80FPS
To my suprise, there is not much difference between internal and external display (5FPS) at 1920x1080. I don't know if the game itselt factor into this, as I don't have other AAA games to test

 

That's what I have tried so far. Thanks for reading

@icttrack, thank you for posting your implementation.

 

Would you mind also doing 3dmark13-FS, 3dmark11 runs (preferrably using an external LCD) and post links to the results?

 

It would also be useful to have the CUDA-Z bandwidth results along with details of your TB cable length.  Can compare against what you'd expect there at https://www.techinferno.com/index.php?/forums/topic/10581-6th-gen-i-core-has-gen3-8gbps-southbridge-pcie-ports/

@Tech Inferno Fan: I am still  new to mobile gaming with eGPU. Even the external screen is from my friend as I normally use laptop. I will consider buying it since now I am not quite happy with the result so far. Even the 3dmark I also don't own so benchmarking is limited. I will let you know the result of my CUDA-Z and TB cable length soon once I have time

@Tech Inferno Fan: My cable comes with Akitio box and it's 50 cm. Here is my CUDA-Z result

The information changes over time. But as I observed, Host to Device Bandwidth stays at 1500+  MiB/s, so it is totally below the  NGFF.M2-32Gbps and not much higher than TB2 -16Gbps (x4 2.0) from your link https://www.techinferno.com/index.php?/forums/topic/10581-6th-gen-i-core-has-gen3-8gbps-southbridge-pcie-ports/  . What can you conclude from this?

Your performance is a little less than expected. This may be due to using a long non-active cable. See related discussion starting about here: https://www.techinferno.com/index.php?/forums/topic/10718-2016-macbook-pros-and-egpus/&do=findComment&comment=151819

@Tech Inferno Fan: I also feel that my system underpeforms given recent benchmarks and gameplay experience. However, my cable is from Akitio and it's exactly 0.5m(1.65ft) long. That's not a long passive cable and thunderbolt 3 cables on Amazon (https://www.amazon.com/s/ref=nb_sb_noss_2?url=search-alias%3Daps&field-keywords=thunderbolt+3+cable)  that claim to transfer up to 40Gbps are exactly the same length. Doesn't seem that Akitio would provide a low performance cable.

I think something else must factor into this

Ensure you are using the high performance power profile. Can also disable C1E using Throttlestop (try EIST too). The latter being a fix from ~2011 to improve SATA performance. Maybe it helps here too?

@Tech Inferno Fan: I tried to use high performance profile. However, it didn't make any difference. I tried Throttlestop as well, but it doesn't support my processor.

By the way, I just bought 3DMark to check my graphics card (I overclocked it a bit) and here is the result:

Fire Strike External Display: 6859

Fire Strike Internal Display: 5712

 

For my tablet specs, it's really a disappointing result. I also notice the card never gets over 70C :(

Are these values the overall score or just the Graphics score?
If it's the first, the Graphic score values would really interest me.

@Splitframe: actually inside the link you can find the graphics score if you click on "Show result details", then Detailed Scores section .

 

I also did some other tweaks (updated the driver, overclocked further, used a separate fan to cool down CPU, ...)  and the latest result is

http://www.3dmark.com/fs/10878039 with graphics score at 11574

Time Spy graphics score: 4000

      Hi!  I'm upgrading from X230 to T470s with a GTX 1060 6GB and am looking for a simple adapter equivalent to my PE4C.  Does it exist?  Everything I've seen are expensive boxes that are overkill for what I need.  Any suggestions?
       
      Thanks!

      Hello everyone, I currently use my laptop for school/work and I know I could have gotten a better one but I didn't pay for it was given to me from my job. I recently purchased an HP omen accelerator and put a MSI 1050 ti in it. Knowing this set up wasn't going to work. My laptop is a i7  HP ENVY x360 Convertible-15m-bp0xx, it doesn't have any thunderbolt ports, it has a USB Type-C port with HP Sleep and Charge. I provided the picture, look at my ignorance. Please help. Is there another way around this, I feel like intel could have came up with a substitute by now.

      Hello! My name is Arman! I from Armenia, and sorry for my English!

      I  discover that there is an Akitio 2, wich can use with iMac 2013 for productivity increase. I want to use akitio 2 with GTX 1050 ti 4Gb, but i dont know how it is intalling on iMac?
      Who can write for me the process of installation ALL equipment (akitio 2 + GTX 1050 ti + imac)? What i must to do? I talking about from the very beginning to the very end. 
      PLEASE everyone, help me. You are my last chance !!!!

      Hi guys. I have had my egpu setup and running fine for the past year or so on my mbp (mid 2012) which has a hdd drive.
      I now want to improve the gaming performance, so I've bought an ssd.
       
      I manage to get through all the steps in eGPU Setup 1.2 but when i go through the bootloader, it says at the very end "No bootable device -- insert boot disk and press any key".
       
      I'm guessing it is to do with my ssd being in the optical drive bay location (i assume this is hd1) and the original hdd (hd0) being disconnected, so windows can't see it when in bootloader.
       
      I think I need to edit the config file for the chainloader, so the bootloader reads the ssd but what exactly do i need to change? 
       
      I tried changing the map section (line 55):
      map --harddrives=1
      if "%DRV%"=="C"
       
      map (%FIRSTHDD%) (hd0)
       
      Changing the (hd0) to (hd1) put the bootloader in a loop!? So I am not sure what to try next...
       
      Any help is greatly appreciated!
       
      Thanks
