There is TB3, TB2 or TB1 eGPU candidate notebook list, but why there is no NGFF M.2 Key "M" candidate notebook list?

The title. Why there is no NGFF M.2 Key "M" candidate notebook list? NGFF M.2 Key "M" is superior to TB3 in terms of speed. I think there should be such a list.

Just some food for thought: There isn't one for Expresscard or mPCIe either.

nando4 edit: there is now an expresscard 2.0 candidate system list.

I think the reason is most people will want a Thunderbolt based solution which is mature and easy to use, while M.2 is basically in every new laptop.

Current: Thinkpad W540 - i7 4900MQ - 32 GB DDR3L - Quadro K2100M - Akitio Thunder2 - GTX 660 OEM

Yeah, I understand that most people do not want to bother with inconvenient M.2 port, but  I assume this site does not have marketing purpose to sole TB ports, other implementations also should be wide covered as good as TB ones, especially if they are superior in terms of speed to TB.

I can see there is a long-time eGPU enthusiast and starter of all eGPU movement Nando4 here. There is a long list of Expresscard and mPCIe implementations on Techinferno, you can check it there. This site is new, maybe he will find a time to copy-past the tables here too someday, although I do not see it necessary, cause those ports will become obsolete very soon.

Copy-and-paste is off-limits. The content needs to be re-authored. We got and, being hosted in the US, had to act on takedown requests from TI for 3 cut-and-paste threads inc DSDT override one. Yes, they're using my content, subject to US takedown, re-owned as "TI Fan", hosted on a DMCA-ignore NL server to avoid takedown to keep it up to now prevent me posting it elsewhere. Dirty.

Yes, expresscard 2.0 died in 2013 with 4th-gen Dell, HP and Lenovo workstations and high-end business notebooks. Thunderbolt replaced it.

stulowe's recent x4 3.0 M2 implementation showing cost-effective EXP GDC hardware is available and stable sparks more interest. But there are three big negatives that come to mind that currently make M2 eGPUs more a technical enthusiasts solution:

Ppl are welcome to start a M2 candidate systems thread here. A good place to look for M2 candidate system's is Cloud Hero's advertising for his M2 EXP GDC: https://world.taobao.com/item/529434284683.htm . Dell's "fat" Precision workstations (M3510, M7510) and Latitude E5570 would be good candidates. They have a SATA and M2 NVMe storage ports so can do a M2 eGPU if using a SATA HDD/SSD. Dell doesn't tend to apply whitelisting.  They also have optional TB3 ports. HP ZBooks have very BIOS security and should be avoided for this purpose.

Thunderbolt is where mainstream eGPU interest comes from (Macbooks, HP/Lenovo/Dell workstations & high-end gaming systems), even if it's slower than x4 3.0  M2.

Techpowerup show us you want a x4 2.0 link to give real desktop replacement performance (> 85%). Then need a x4 3.0 link's if using accelerated internal LCD mode for the extra display traffic. 32Gbps-TB3 then offering a real desktop-replacement eGPU solution if using Optimus/X-Connect to drive the internal LCD.

3. requires underside access to the system like mPCIe eGPUs. Will there also be whitelisting on the slot?

HP ZBooks have very BIOS security and should be avoided for this purpose.

 

 

   

Could you please let me know a little bit more about those 2 possible problems? What does 'require underside access' mean? Sorry, I don't know that expression...

And, what does it mean whitelisting on the slot? Can we know if our computer applies whitelisting somehow? and what would affect in the eGPU case?

Trying to get the parts needed to get a EXP v8 M.2 rig for my E5450, by underside access I believe he's referring to opening up the laptop  and working the cable from the ePU dock to the  M.2 port located on the bottom facing side of the laptop, requiring unscrewing screws and possible sacrificing wifi/hdd slot to allow connecting the  eGPU dock as opposed to TB where it's simply plug'n play.

I think a decent candidate might be the Xiaomi Mi Air (13) for the dual m.2 SSD slots it possesses. The big problem with that machine for me is the soldered RAM, which they tried to work around with a dGPU, but I'd be very interested to know how it runs with a M.2 GDC Beast and a top end card. I'd definitely like to know more about the 10xx problem mentioned by nando4 too.

Thread resurrection, but the Thinkpad P50 would be a viable candidate. It has 2 m.2 slots, but I dont know if it has 'whitelisting'.
