Guys I owned Mantiz Venus .. and now I want preorder GeForce RTX 2080 Ti

It is good choice?

Not be here some block small Thunderbolt3 bandwith?

Or is better create preorder only for non-Ti version? I haven't problem with money so if not here some problem I jump into river Ti 🙂

Now I have for mantiz my second laptop HP Spectre x360 13 2018 black and gold version.

Pre-ordered = HP Spectre x360 13 Poseidon Blue (2019) (i7-8565U, 16GB DDR4, 512GB SSD)
LAPTOP = HP Spectre x360 13 Dark Ash Silver (2018) (i7-8550U, 16GB LPDDR3, 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 = BenQ EX3203R | ROUTER = NETGEAR Nighthawk X4S R7800
KEYBOARD = Logitech G810 Orion Spectrum | MOUSE = Logitech G305 Recoil

What host laptop are you going to pair it with? If it's the one in your signature, I'd say upgrade to a more powerful TB3 laptop before spending $1,200 on the RTX 2080 Ti.

My laptop have Thunderbolt 3 4x pci lanes - HP Spectre x360 13 2018 with 4core i7-8550u, 16GB DDR3L

Previous year I have only HP Spectre 13 2017, before christmas I sell it and buy desktop plus lowcost laptop, but this year few months back i sell my laptop and again bought HP Spectre x360 13 but in version 2018 with 4core cpu.

My signature is more months old, maybe is again good time update it sorry, so I update it.

In short, no one really knows until they are released and tested.  I have ordered one myself to use in a Sonnet 550 and 2018 MacBook Pro.  I am also going in assuming that the typical ~10-20% FPS drop generally associated with an eGPU versus direct PCIe will remain.  Should it work though?  My assumption is yes, performance impact though is unknown.

Hi Shrapnl, I'm also hesitating whether I need an RTX or just an older GTX for my 2018 Macbook Pro. For the first card all I'm concerned is how long it can take before a mac-compatible solution come out. How do you think of that? If it's gonna take a whole year waiting for a customized solution, what's the point of buying it now? Thanks~

I have yet to list my system & eGPU hardware or link a build guide in my signature. I will do so soon to give context to my posts.

I was wondering the same thing. Also I wondered when there would be diminishing returns on the GPU due to oversaturation of the solution's bandwidth. I am considering gtx1080ti vs rtx2080ti in a razer core x for a mbp15 2016. I assume there's no clear answer til the cards come out, but i have been seriously considering cancelling my rtx preorder if it doesn't perform well.

It really depends on resolution. Even with the expected 20% TB3 degradation the 2080 and especially the 2080ti will still be able to do 4k 60fps at ultra settings in most games based on speculation of performance improvements vs the previous 10 series GPUs. If you will be doing 1440p or 1080p then get a marked down 1080ti. If 4k go all in and get the 2080ti. 

Either way way I would definitely wait until benchmarks and egpu compatibility has been confirmed.

While I don't have Mantiz Venus, I do have Sonnet Breakaway Box 550 and Aorus X5 V8 gaming laptop, which has full TB3 support, and here's my 3DMark scores with Nvidia FE 2080 Ti

2080 Ti (Nvidia Founders Edition) (eGPU Sonnet BB 550)

Time Spy Score: https://www.3dmark.com/3dm/29668880 | 9831 [Graphics of which: 10518]

Time Spy Extreme Score https://www.3dmark.com/3dm/29669861  | 4879 [Graphics of which: 5700]

 

At this point this being a laptop (even if gaming), the CPU seems to be a factor in total score, which is why I provided the Graphics numbers separately.

For comparison, same laptop, same eGPU (Sonnet 550), but with EVGA 1080 FE:

Time Spy Score:  https://www.3dmark.com/spy/4724118  | 6514 [Graphics of which: 6410]

Time Spy Extreme Score:  https://www.3dmark.com/spy/4724190  | 3182 [Graphics of which: 3206]

I hope this helps people with gaming laptops deciding whether to get 2080 or 2080Ti over TB3. It's still worth it, even with the TB3 bandwidth loss.  Note that Sonnet officially list the Nvidia 2080 Ti  FE as compatible with 550, not every eGPU out there may be, and not every laptop with TB3.

For clarity, Aorus X5 v8 comes with GTX 1070 built in, and although in some tests 3DMark shows it as the first card, the score is 100% based on the 1080 eGPU / TB3 run card (I know as I've watched which video card gets loaded, while the tests are running.). Obviously the same applies for the 2080 Ti tests, though not sure why 3DMark decided to list 2080 Ti as the primary card and not the 1070, as it was in the 1080 eGPU tests. 

To save you doing the maths, based on the above numbers 2080 Ti performs around 55-61% better than 1080 on the same setup over eGPU / TB3.

I expect future NV Drivers would improve that even more (I had to do my 1080 eGPU tests on the previous version (416.16) as I had problems with the latest (416.34) and lower 3DMark scores.

The 2080 Ti tests were done on the latest (416.34) drivers, no problems so far, but as I said I'd expect higher score with future drivers. I feel like Nvidia is still playing around with the 2080 / Ti drivers.

----------

Overclocking Benchmarks for the 2080 Ti FE run on Sonnet BB 550 eGPU over TB3 on Aorus X5 V8 gaming laptop:

Same setup as earlier, this time using EVGA Precision X1, GPU (Clock + Memory) were overclocked to stable state as such:

Memory + 700MHz / GPU + 140MHz / Power Target: 121 (max). Fans on Auto Control.
 
Time Spy: 10398 [Graphics: 11373]
Time Spy Extreme: 5318 [Graphics: 6174]
Fire Strike Extreme: 12761 [Graphics: 13249]
The above overclocking settings increased 8-9% the performance.
