Recommended eGPU adapters/enclosures


Thunderbolt (max=16Gbps) US$189 AKiTiO Thunder2 PCIe Box

NGFF.M2 PCIe (8Gbps): EXP GDC V6/7

Expresscard_or_mPCIe (max=4Gbps) BPlus PE4C V3.0

 

Recommended systems: 6th gen Skylake | 4th gen Haswell | 3rd gen Ivy Bridge | 2nd gen Sandy Bridge


Units with a Thunderbolt or ExpressCard slot/port or with a user contributed mPCIe eGPU implementations are listed below. These are all Sandy Bridge or newer offering faster 5GT/s-per-lane PCIe 2.0 mPCIe/ExpressCard slots than previous 1st gen i-core and Core2Duo systems using only PCIe 1.x 2.5GT/s slots.

The cost effective ExpressCard is a dying standard. This means future eGPU implementations will be using either the mPCIe (WLAN) or Thunderbolt port. mPCIe present additional issues: the slot may be a whitelisted slot requiring third party program or booting with wifi, then swapping it out to activate it. mPCIe also adds the hassle of cabling it via underside covers with no concurrent wifi unless get a USB stick wifi. Note too that a USB 3.0 DIY eGPU product isn't likely to happen due to USB-to-pcie driver issues.

The highest performance eGPU solution is one using a Thunderbolt port. Though TB1's 10Gbps doubling of bandwidth questionable value over the the cost effective expresscard solutions. TB2's 16Gbps is however a worthy upgrade the only problem being the lack of notebooks with TB2 ports.

Expresscard/mPCIe systems are capable of attaching very low cost eGPUs, eg: GTX650 for Pre-purchase FAQ -> 2. How can I check if my notebook is compatible with an eGPU?. Refer to Pre-purchase FAQ and Getting Started guides on the main page to identify what parts are required for an eGPU setup.

Key

TB3 : 40Gbps "Thunderbolt 3" (~x4 3.0) - 96%-99% of x16 2.0 desktop performance
TB2 : 16Gbps "Thunderbolt 2" (x4 2.0) - 88%-94% of x16 2.0 desktop performance
TB : 10Gbps "Thunderbolt 1" (~x2 2.0 + 12.5%) - 73%-86% of x16 2.0 desktop performance
EC or mPCIe : 5Gbps (x1 2.0) expresscard or mini PCIe slot eGPU interface. Systems with an Intel iGPU and NVidia Fermi/Keplar/Maxwell sees the NVidia Optimus driver implement x1 pci-e compression, accelerating DX9 performance by 100-300%. This is referred to as x1.2Opt (Opt=Optimus) in the DIY eGPU documentation.

.......... : recommended lightest or most powerful in that LCD size class
purple : ULV notebook or ultrabook. Ultrabooks come with a non-removable lower-capacity li-po battery and mSATA SSD.
$ : Add US$14-delivered slim USB DVD if require an optical disk drive.

 

 


Skylake, 6th generation 14nm i-core (2015)

13" Macbook Pro Retina$ TB2 3.46lbs (1.57kgs). 0.71" thick. 1600P.

 


Haswell, 4th generation 22nm i-core (2013)

Haswell's ~30% battery life gains over Ivy Bridge are only within the ULV platform which, for the first time, integrates the chipset on the CPU die. The full-powered (37W/47W M/MQ/HQ CPUs) Series-8 platform sees very little performance or battery life gains over Ivy Bridge. Anybody requiring i7-quad performance may wish to look at the more extensive and affordable Ivy Bridge range instead.

Ivy Bridge, 3rd generation 22nm i-core (2012)


If require longest possible battery life then recommend a Haswell ULV system shown in purple. If wanting i7-quad performance then note that Ivy Bridge runs cooler than Haswell as discussed in http://forum.techinferno.com/throttlestop-realtemp-discussion/6958-haswell-step-backwards-ivy-bridge-i-have-some-shocking-tdp-results.html#post95181 . Ivy Bridge are currently the best bang-per-buck eGPU candidate systems.

NOTE: The HP Probook 4x40s and Lenovo Ex30 low cost business notebooks no longer have expresscard slots in the Ivy Bridge series.

 


Sandy Bridge, 2nd generation 32nm i-core (2011)

The hosting Series-6 chipset has, for the first time, pci-e 2.0 connectivity on the Southbridge that host the expresscard or mPCIe slot. There is no USB 3.0 integrated on the chipset so any machines that come with USB 3.0 typically attach a Renesas USB 3.0 controller on the Southbridge.

i7-quad users note: Ivy Bridge improves on Sandy Bridge by using more efficient 22nm tech compared to 32nm used in Sandy Bridge. Typically i7-quad Sandy Bridge CPUs will see significant TDP throttling where it only reaches a x27 multiplier in 4-core mode and consumes 10-14W more power under load as discussed. Meaning it's maximum performance is considerably lower than an Ivy Bridge CPU at the same power limit!! For that reason I recommend the Ivy Bridge range for best performance.

Making this a read-only thread. I'll edit in new additions as they appear.

Thunderbolt3 equipped eGPU candidate notebooks

How does Thunderbolt 3 affect things. Intel said that thunderbolt 3 officially supports PCIE-x4 3.0. Can I buy any laptop/tablet with a thunderbolt 3 port and run a GPU from it (of course with power and docks)? or is it up to manufacturers to allow this.

P.S. I have an updated list about laptops with a Thunderbolt 3 port (rumor or otherwise), feel free to take them or if you want Edit access, tell me your email (by default, you can only view and comment)

      Hello guys ...

      i wanna make sure that everything is going to work fine with my laptop so i got some questions

      First of all my laptop is Lenovo Z51-70
      CPU: I5-5200U 2.2ghz
      iGPU Intel HD 5500
      dGPU:AMD R9 M375
      Ram: 8GB (will raise it to 16GB)
      HDD: 1TB stock one
      SSD: 120GB (for my games and windows only)

      now i investigated  a little about eGPUs and found that i need a M.2 or thunderbolt, i've found that my wifi card use a M.2 a/e key aka ngff, so i will be using the GDC Beast NGFF version

      to the bad part / question part

      What do i need to know other than the stuff above?
      what is the white-listing thing? i found on support forums that my laptop support some wifi cards only and it's bios cann't be modified according to bios modifying forums (not here)
      in same time saw some posts on reddit that says if ur bios have UMA graphic option then you will need to disable PAX / WIRELESS and enable UMA and it will work fine, the question is that true?

      i wasn't able to find anyone who did it on Z51-70 i found only 1 post on reddit for Z41-70 (which after research found that both are using same M.2 a/e key slot and also same bios... but the one who posted only replied that it's recognized with some errors and never replied back with any updates so still not sure about it.....

      Hi, just a quick question what would be the best EGPU adapter, because i see the really expensive ones but then you have the 400$ dollar one that Lowspecgamer used. Which do you guys recommend ?

      Hello guys,
      Thanks for this incredible forum, I hope I will learn a lot from the gurus ! 

      I am trying to make my eGpu MSI GT X970 work on my laptop   with K1100M integrated GPU. 
       
      This are my specs:
      CPU: 2.7GHz Intel Core i7-4800MQ (quad-core, 6MB cache, up to 3.7GHz with Turbo Boost) PSU : ??? Graphics: NVIDIA Quadro K1100M / Intel HD Graphics 4600 RAM: 32 GB Storage: 1TB

      I got a V8.0 EXP GDC Laptop External Independent Video Card Dock  with the express card version ( I am not really hw savy) and I am looking for a good psu to power my MSI GTX 970 4G  
      Could you kindly suggest a good PSU that i could use to power this GPU ? I am also willing to do as many experiments needed
       
      Thanks for reading my post

      Hello everyone.
       
      I put on a eGpu setup after quite a bit struggle 2 years ago and I used play games just fine. After a while I sold my graphics card gtx 970.
      Now since 2 days I am trying to put the eGpu setup back again this time with a Gtx 770.
      I couldn't understand the problem. I can shut my dGpu off with diy 1.30 setup. ( usb booted)
      And my laptop sees  gtx 770 along with my igpu Intel HD graphics 4000.
      After driver installation when I try to play a game laptop is tring to use iGpu instead of Egpu. (tried to delete and install driver few times)
      With MSI afterburner I can see  eGpu is  %0 all the time.
      Can it be power problem cause graphic cards fans ( Msi gtx 770 twinfrost ) are working all the time they dont stop.
      Or what else can it be. 
      Thx.

      In case you own a Lenovo Y410p or Y510p laptop, you might be interested in upgrading its performance by installing an external graphics card. Ultrabay eGPU adapter designed by @gerald was proven to be a convenient plug-and-play option to do exactly that. However, for a long time only an AMD-branded GPUs could be used due to limitations in the Lenovo's stock BIOS. The purpose of the modified firmware presented here is to expand the range of available GPUs by enabling Nvidia support on Gerald's Ultrabay eGPU adapter.
       
      Huge thanks to:
      @MWichni - For efficiently assisting me during the development of this mod. By flashing dozens of BIOS builds over the course of several weeks and thoroughly describing the effects observed (or the lack thereof), he enabled me to fully understand necessary parts in BIOS structure and come up with a final solution. @svl7 - Whose unlocked BIOS / Whitelist mod has served as a basis for this modification. His discovery of a security hole in V2.07 BIOS has provided us with a convenient BIOS flashing method that does not require a physical programmer. The Unlocked BIOS and WLAN whitelist mods originally designed by him are also implemented in this BIOS mod. @gerald - For designing the aforementioned adapter. Without it, all this work would make very little sense.  
      Key features:
      Resolves the "40-second reboot" issue normally encountered while using Nvidia graphics cards with Ultrabay eGPU adapter, thus allowing all Nvidia cards to be used. Based on the latest V3.08 BIOS. Includes Svl7's WLAN whitelist removal mod - for the convenience of aftermarket WLAN card users. Includes Svl7's BIOS debug menu mod - for the ease of experimentation with newly available features, e.g. attempting to use Nvidia Optimus to pass eGPU video back to laptop's display.  
      NB! Svl7's Debug Menu is not a toy! It contains a lot of options that are either not supported or partially supported by the hardware platform and/or can disturb its normal operation or prevent the PC from booting up at all. Any of the entries not originally present in the stock BIOS should be modified at your own risk!
       
      DISCLAIMER:
      ANY MODIFICATIONS YOU ARE APPLYING TO YOUR HARDWARE ARE PERFORMED AT YOUR OWN RISK! AUTHOR OF THIS MOD DOES NOT HOLD ANY LIABILITY FOR LOSS OR DAMAGE RELATED TO USING THIS SOFTWARE.

      Installation instructions:
       
      If things don't go right:
       
      Error 43:
      If you intend using the GTX10XX-series Nvidia card as the eGPU (which you probably do), you are very likely to encounter the infamous Error 43 in Windows Device Manager. This is a widely known issue in the eGPU community and is not related to this particular mod in any way. Following this guide thoroughly will in most cases resolve the Error 43 issue.

      P.S.:
      Version of this mod for Lenovo Y400/Y500 models is coming soon!
