Expresscard 2.0 eGPUs – pros, cons and candidate notebooks

Expresscard 2.0 (EC2 or 4Gbps-EC2) is a lower cost and lower bandwidth eGPU interface alternative to Thunderbolt found in older 2011-2013 PC notebooks. In this article you’ll find the pros, cons , adapters; and a full listing of EC2 equipped notebooks including recommended notebooks provided to help decide if this is the right eGPU interface for you. Here ◄ are eGPU.io user submitted EC2 eGPU implementations as an additional reference.

Update: two (expensive) 2015 6th generation Lenovo workstations have a rare Expresscard 3.0 (8Gbps-EC3) port here . They each also have Thunderbolt 3 ports.

Pros of an EC2 eGPU solution

 

  • ready availability of cost-effective EC2 candidate notebooks. Many are durable business grade systems being offloaded by companies, still in good condition, on the second hand market. 3rd/4th-gen quad-core systems still performance competitive against even the newest 7th gen quad-core equivalents (example).
  • is a hotpluggable interface. Important due to NVidia’s GTX10xx cards requiring this for functionality which prevents mPCIe/M2 wifi or PCIe SSD slot interfaces from being used to host a eGPU (reference).
  • is a direct PCIe interface often yielding a plug’n’play solution, or may require minor Windows error 12 tweaking. Comparatively, Thunderbolt is PCIe interposer silicon so can present more challenging eGPU detection issues.
  • availability of an affordable EC2 eGPU adapter starting at US$46

Cons of an EC2 eGPU solution

 

  • it’s 4Gbps of bandwidth delivers compromised performance compared to a desktop, 32Gbps-TB3, 16Gbps-TB2 or 10Gbps-TB1 Thunderbolt system. 16Gbps (x4 2.0) deemed necessary to hit 85% desktop-level performance (reference).
  • an external monitor attached directly to the eGPU is required to maximise performance on the narrow 4Gbps eGPU bandwidth (reference).
  • candidate notebooks are older and thicker often with poorer LCD colors, viewing angles and resolutions; and slower storage than newer systems.

 

Which EC2 system to choose?

 

Suggest avoiding 2nd-gen i-core systems due to their lack of native USB 3.0 support and the quad-core CPU variants will TDP throttle well before reaching their 4-core turbo performance limit due to their more power hungry 32nm lithography.

That then leaves 4th and 3rd gen systems, with little separating them other than the latter maybe using mSATA SSD technology, newer dGPUs and perhaps better LCD technology. Some even have a Thunderbolt2 (TB2) or Thunderbolt1 (TB1) port.

Dell Latitude/Precision systems are the easiest to configure for eGPU use and so are the pick of the bunch.

HP Elitebooks/Probooks with dGPUs do not have the iGPU wired so cannot provide NVidia Optimus accelerated internal LCD mode. Aim for an iGPU-only Elitebook if that is a desirable feature.

 Dell Vostro 3750 not recommended for Express Card? Correctly understood? To which (in your opinion) the connector of this laptop is better to connect this adapter, to Express casrd or m Pci-e (for higher bandwidth (for speed))?

EDIT: Do Express Card 2.0  4 Gb/s  speed in both directions ()? The sum will be 8 GB/s, right?

What is the difference between the adapter 9.0 and 8.4d?

Notebook Dell Vostro, Intel I7-2670QM, 8 GB.  The video card will be connected via Express Card 2. Power Supply Dell 220 Watt. Please advise which video card better to connect 1060, 1070 or 1080? For gaming and video editing in Premiere and After Effects?

For gaming, a GTX1060, as with an older slower CPU and over Expresscard you’re going to struggle to utilize the more potent cards. For professional programs, the PCIe connection width matters little, so the answer is typically “the one that satisfies your professional needs” or “whatever you can afford”.

Thank you! If I understand you correctly, the 1060 is the most optimal for the equipment that I have. Did I understand you correctly?
Palit 1060 super jetstream 6gb –  normal option?  Or another card?

Out of the three you listed it is the one that makes sense. As for the model, get the cheapest one that still has a decent warranty. You do not need to pay extra for an overclocked model or anything.

It also depends on the quality of customer service they provide. In the US I swear by EVGA, but it might be different in Russia.

The cheapest one that has 6GB of VRAM. With an eGPU over Expresscard, there is little reason to opt for the more expensive overclocked versions, as any gains will be minimal anyway.
In the US, this is cheapest 6GB model: EVGA GeForce GTX 1060 GAMING, 06G-P4-6161-KR, 6GB GDDR5, ACX 2.0 (Single Fan)

Considering it will be sitting on an open eGPU adapter, overheating is literally the last of your worries 🙂
Any other model will work as well, like I said, I am just trying to save you some money.

Thank you! Can be more expensive model, I’m ready to pay for the speed and good model of the video card, the main thing is that it then worked well. 
Are there faster and more suitable cards for my processor and laptop?

 GTX 1070 will not work for my system via ExpressCard2 for video editing? Or is it better than 1060? If 1070 is more suitable, then I’m ready to pay and buy it.   1060 or 1070 for mounting?
