waaal!

it's a good back to back test and a clear explanation of H-D and D-H. I should buy your product!

HI:

Then join the Group buy. 😀

Hi!

I am really looking forward to you posting pics of a working X1 Carbon 5gen + Mantiz eGPU setup. Please don't keep us waiting Smile

Thanks in advance!

   

There's no problem at all, I'll do it on Monday, the Venus is in our office.

 

   

@Mymantiz_John

Just a polite reminder on posting the X1C5 + Mantiz pics / tests Smile Mantiz working well with the Carbon is an important factor for me when deciding on both the laptop and the enclosure. I would be really grateful if you could post some update on the issue - thank you in advance! Smile

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

 HI, dunno what it went wrong with upload the pictures.

  

Thank you for running the tests and uploading the pics! Could you also post the 3dMark interpretation of the result, sth as here:  http://www.3dmark.com/3dm11/6739198

Thanks in advance!

HI:

I would like to clarify an important concept here.

first. if we are talking about the EGPU , not a storage. actually the " Performance " won't be impacted by the H-D Value. Performance is the D-H ( after computed, calculated package ) send back to Host.

 

Mantiz Venus also delivering half H2D bandwidth like the AKiTiO Node

 

@John, Pls continue asking Intel to correct this problem. As is now, the Mantiz Venus with the half H2D TB3 bandwidth  problem, (1158MiB/s) will deliver less gaming FPS than a TB2 system (~1400MiB/s) when using an external LCD!!

It and the also TI83-based AKITiO Node having the same problem:  ALERT: AKITiO Node half-H2D CUDA-Z performance issue

 

The H2D bandwidth is critical in providing good FPS. It indicates how fast the TB3 channel is in sending data from the CPU to the eGPU. Traffic such as games texture maps. That is the primary traffic direction when using an external monitor attached to the eGPU.

The D2H becomes important when using Optimus or X-connect accelerated internal LCD mode where display traffic is send back from the eGPU to the iGPU.

3dmark benchmarks aren't bandwidth heavy enough to pick up this H2D anomoly.

Above: Late-2016 13" Macbook Pro + GTX980@TB3-32Gbps (Mantiz Venus) + macOS [itsage]

HI: I did some experiments to see the internal VS external display performance in Mantiz Venus (TI 83 H-D 12Gb ) VS Razer Core ( TI 82 H-D 21Gb )

aaa
BBB

I saw no difference in Unigine Heaven Benchmark in FPS.

As mentioned in my last post, 3dmark ( and now Heaven) are not heavy bandwidth apps. Internal vs external benchmarking is irrelevant. It's using the D2H bandwidth, which isn't affected.

Try some games that stress the H2D bandwidth. eg: Far Cry Primal that saw almost  a 15FPS drop (89->74) going from x4 3.0 (32Gbps) to x4 2.0 (16Gbps) here, which is equivalent to the half H2D problem we are seeing here.

Needless to say, the TI82-based Razer Core isn't affected but the TI83-based Mantiz Venus, AKiTiO Node and probably XG Station 2 are. Customers who are being sold a Mantiz TB3 enclosure are expecting TB3 throughput.

I can see Mantiz Venus purchase disputes or refunds down the track if this problem isn't fixed before enclosure delivery.

Thanks for your valuable suggestions and comment. I will test the game FPS both in Razer core and Venus tomorrow.
