I have a 1080ti + Mantiz Venus and I can play Hitman and Dishonored 2 at 4k 60fps with high settings.

However there are still issues at play overall, of which anything we can do to minimise would be welcome.

In testing with Venus & 1080 Ti, I'm pulling 3D Mark scores closer to a 1080. Still well and truly playable, but a drop of 30% performance is still a little painful.

30% performance compared with?

Hi John,

This was comparing a 1080 Ti running on a 6700T in a normal desktop vs a 1080 Ti (which was driving the monitor) running on a Skull Canyon NUC with a 6700HQ CPU & a Mantiz Venus dock.

The test was 3DMark's Timespy benchmark, which runs at 2560x1440.

The desktop system scores roughly 9000, the thunderbolt egpu system scores about 7000.

Now we know from PCI-E scaling, that a 4x PCI-E 3.0 will take about a 7% performance drop compared to a full 16x lane, which leaves 23% or so roughly of improvements to try for. Of course with Thunderbolt encoding times, your probably not going to achieve all of that difference. 

I do somewhat wonder if an optical thunderbolt cable might improve performance. But I haven't seen any made for TB3 spec.

Thunderbolt 3 Theoretically provides the PCIex 4, but actual Data transmutation rate is only 22Gb.  I also found that more high end card between eGPU VS DT, it will lost more, around 30~33%. 1070 is around 2x%. something like that.

Hi Johny, can I have novice question - what you mean that new firmware will be dynamical?

You mean for example: when I will have in my Venus for example Fury X and HDD, but in time when I will be using GPU for games and zero percent using hdd so Venus will work 100% for GPU. And when I will be for example in same time playing and copy files into hdd so speed for GPU will be little smaller .. and this will work dynamical? so when copy files will be finished so again GPU will have max performence

An upcoming FW means: 

We had cooked the firmware and this firmware is waiting for Intel approval. Will be released @ any time.

Dynamic Means;
  If you don't use any HDD or SSD through the IP ports, CUDA Z will stay @22xx MiB/S. But while you used, it will be reduce a bit to 21xx MiB/s. ( my USB 3.0 HDD occupied around 98MB/, if you use 3 USB HDD copying file, it will be reduce to 22xx Mib/S-300M=18xx Mib/s. and once you finished the tasks, it will be back to 22xx Mib/s

 

 

 

 

 

Really? :-O

Hm so if it will be working as you say, so it will be best 🙂

So I can have in Venus for example hdd and when I not copy etc so firmware will be working est for gpu, and when I start copy files so on this small time Venus reduce speed for gpu and after finished copyed again switch on full power on gpu.

 

And Johny what when I plugin my Logitech PowerPlay directly into Venus usb on rear? how many this reduce my gpu?

(powerplay is new mouse pad from Logitech, which can plugin mouse directly via nano receiver plus this mouse pad can charge my mouse via wireless)

LAPTOP = HP Spectre x360 13 Dark Ash Silver (i7-8565U, 16GB DDR4, 512GB SSD)
EGPU = Mantiz Venus MZ-02 Space Grey + PSU Corsair SF600 600W 80 Plus Gold
GPU = PowerColor AMD Radeon RX Vega 64 8GB HBM2
DISPLAY = Samsung C27FG73 | ROUTER = NETGEAR Nighthawk X4S R7800
KEYBOARD = Logitech G810 Orion Spectrum | MOUSE = Logitech G305 Recoil Black
CHAIR = DXRacer Racing OH/RV001/N
PHONE = OnePlus 6T MidnightBlack (8GB LPDDR4X, 256GB UFS2.1)

I recently received the Mantiz Venus and am using with a new 13.3 Razer Blade Stealth. My impression was that this issue had been fixed on the Venus, but I am still seeing it running CUDA-Z. Is there a firmware update I need to do?

Hi guys, not sure if I am being daft, but how do I get this to run on internal display under Mac OS 

 

What is a 'Ghost external display adapter' and where do I get one from?

You can follow goalque's instructions to force internal display eGPU acceleration in macOS.

Guys today I received my Mantiz Venus.
In box was +- 13cm long black tape, on what is it?

footstand, you can tape it on the BTM of the enclosure.

But just one foot? Not two for front and back in the bottom? I thought it was mine, that just came with one by mistake...

Why everyone is testing h2d issue with heaven benchmark? Heaven doesn't use that bandwidth. Not even every game is using it in full power. My suggestion is to use a game from Ubisoft called "Assassin's Creed Black Flag". With everything on max (except physx) on areas like jungle (a lot of trees, bushes etc.) it seems like game really struggles due h2d. GTX1080 performs at 60fps on desktop whereas on egpu it gives 35-46 fps in those areas. 

Black Flag is absolutely shit at being optimised to run on PC. John has already provided actual game benchmarks, apart from Heaven. 

Also, PC performance and eGPU performance isn't going to be identical. I struggled to get good performance out of Black Flag at 1080p (60fps constant) back then, more than a year after it released, and I had quite a decent PC for the time. (4790k, 970)

The fact that you need a 1080 for a game released in 2013 to have it running at 60fps says it all. I have a 1080ti + Mantiz Venus and I can play Hitman and Dishonored 2 at 4k 60fps with high settings.

pff.. unoptimized game - even better! If 1080 works 60fps in jungle on pc while egpu not giving 60fps - something is wrong with bandwidth. GTA 5 works awesome everywhere (including limited h2d speed), I agree, but I think that Black Flag is perfect scenario to test. If Mantiz Venus will show lower fps in jungle than Akitio Node (as example) - H2D plays significant role in perfomance. Anyway, in my opinion, sharing heaven\valley scores to prove h2d speed insignificance is nonsense. 

 UPD: Not every game is affected by H2D speed.

Sorry to take this off on a tangent from H2D; I have a burning question someone might be able to answer about the enclosure (loving it so far btw!) Smile

I remember reading back about the Custom PSU w/ 550w, I soon plan to get a Vega 64 Water-cooled in there somehow once the card has launched, rocking my old HD 7950 while I wait.

So this is a~345w TDP, I realise I would be pushing the PSU hard; If it say were to die, would I be able to replace it with any other SFF PSU of the same wattage?

- were there some customisation for the 87w PD that would make this infeasible?
