Do you plan to have a European distributor?

Sorry guys, I got a little lost here with this latest chatter. 
Please correct me if I'm wrong, but what I'm taking away from this is that:

PCIe portion of TB3 link is used for the GPU itself, running at 32GB.  
The remaining 8GB of the 40GB spec is used as a USB channel, providing bandwidth to the other items on board (Network, USB, Sata)

If this is the case, then no GPU performance lost utilizing the extra ports, compared to running a GPU on the Node without additional ports.  

 

   

The official document explains it clearly:

https://thunderbolttechnology.net/sites/default/files/HBD16235_Thunderbolt_TB_r05.pdf

As for eGPUs, it’s always PCIe 3.0 x4 at both ends, roughly max 2750MB/s. However, TB3 should be able to provide bidirectional 40Gbps connection if we count the protocols together, dynamically switching between USB, DP, and TB.

"However, it is key to understand that the Thunderbolt interface is bidirectional, while display traffic is mostly outbound from the host system. If the Thunderbolt link is using a PCI Express device to ingest traffic to the host system, that PCI Express bandwidth will be largely unaffected by outbound display traffic (outside of some flow control impacts)."

That's why we never use PCI-e Trace for the other purpose. so, simply saying, PCI-e 32GB & others will be used for USB 3.0 interface including the Lan & USB 3.0 Hub.

I am pretty lost too. This was that I understand, but then someone says something that makes me doubt it. I think that this topic should be clarified.

Personally, I don't care having extra ports: usb, ethernet, sata, if this will be a lose of performance in my GPU, which is the important thing  here, not the other extra stuff... The more performance in the GPU the better, and if we are losing for the rest stuff, I prefer to have just a GPU case without extras like the node. Cheaper, and faster. That's why is really important to clarify.

Thanks!! 😉

Hi All:

Let me clarify, there's no performance lost in GPU unless the FW set it to be lower than the 32GB. Those extra ports including USB & Lan are nothing related with the PCI-e lane. it is a 40GB bandwidth and PCI-e x 4 occupied 32GB. that's it.

Fantastic, thanks for the link to the official doc, and the clarifications!
My node pre-order keeps getting delayed.

How soon can I get my hands on the Venus?!
This is exactly what I want!

Looking forward to the product.  Thanks all.

I got all the components put together last night. It works great in Windows 10 with my 2016 13" touch bar MacBook Pro. There was no error 12 which surprised me because the non-touch bar MBP has that error. The Mantiz Venus enclosure also works well in macOS. The only non-functioning feature is the Ethernet port in macOS.

Sad to hear that about the OS X ethernet.  

I assume theres a driver that is installable though.

 

Any way we can confirm is this is backwards compatible to TB2  with the apple adapter.
