@arizor, I'm really excited for your results next week. I have the same MacBook and I get a TimeSpy graphics score of 13100 with my 2080 TI. It's good to see the eGPU bottleneck hasn't fully caught up yet.

 

Definitely good news. The more GPU bound you are the less the performance loss is within reason. It looks like a 3080 will be AT MINIMUM about the same as a 2080Ti desktop system, and in many cases much faster. Good times!

I've done a bit more RTX 3080 testing in my build link if anyone wants to see some more data.

Very hit and miss, and using it to boost my VR (Index) looks like an absolute no-go.

I'm continuing to make edits/updates to the main post. Please let me know if anyone finds anything I've missed or calculated incorrectly, or has any new data I should add or be made aware of. Thanks!

Real shame, Huge interest in the 3080 is improving my Index results at 90hz. Hopefully this is a matter of drivers more than anything.

 What res/refresh do you run at? It's my understanding the 3XXX series is all about maintaining good frames at 4k+ resolutions more than anything else. If I can comfortably sit at 90fps at 100-130% res on my index for most games, I'd be a happy camper.

Hey folks,

So I'll try to do more tomorrow, but initial reports with my Ventus 3080 (all other specs the same as in sig, just swapped out Vega).

Everything is super crashy, blackscreens happen often.

When Time Spy ran fully, graphics scored 15k.

Tomb Raider benchmark can run fine, and when ran at 4K with ray tracing and DLSS, scored 75FPS average (approx 10-15% below desktop depending), but often it often crashes with an error "DXGI_DEVICE_ERROR_HUNG".

Control also tends to crash within a few minutes.

edit: I'm also seeing this error in my Device Manager for "Broadcom Serial Bus Driver over UART Bus Enumerator":

This device cannot start. (Code 10)

{Drive Not Ready}
The drive is not ready for use; its door may be open. Please check drive %hs and make sure that a disk is inserted and that the drive door is closed.

Not sure what's going on there! Any insights @itsage ?

Small update - installing the “studio” drivers (instead of game ready) and under clocking the card by 50mhz on afterburner has improved stability substantially. 

The boost clock was going far over 2000 (up to 2140) with the game drivers and it looks like that’s causing issues.

shadow of Tomb Raider is now benchmarking at 70fps maxed out with DLSS and raytracing, but it’s stable so I’ll take the small hit until they fix drivers.

edit: Yep this has fixed all stability issues, just at the cost of a performance hit.

Port Royal score is 9k, so about right for an eGPU running underclocked (looks like desktops clock around 11k). 

Basemark score is really impressive, it runs unbelievably quick through: 17k on Vulkan, 16k on DX12. For comparison, my Vega64 scores around 6700.

@arizor,

So I don't have the memory problems unless I overfill the memory of the laptop and GPU

There are some reports out there that there is specifically a problem in some cases if the card is running at over 2000MHz. Which is odd because I think the stock boost clock is only like 1710Mhz. I saw one card that raised that to 1755Mhz.. I guess there's some that factory overclock to north of 2000Mhz... maybe just try changing that to like 1900Mhz max?

@odin, yep that’s what I did, undervolted it too, no issues since, running great.

 

edit: to further clarify, I undervolted and set the boost limit to 1900.
