Hi!

Finally took a leap and graduated from being a lurker Smile Am finally able to share my upgraded gaming laptop with an eGPU with the ff. specs:

Laptop: 2019 Lenovo Legion Y740 15"[9th,6C,H], 16GB RAM, Windows 10 20H2

dGPU: RTX 2060 (Mobile)

eGPU: Mantiz Saturn Pro + MSi RTX 3070 Ventus 3x OC

External Monitor: Xiaomi Mi Surface 34" (3440 x 1440p)

 

Installation:

  • Ran DDU
  • Restarted laptop, with eGPU plugged in
  • Disabled dGPU
  • Installed drivers for RTX 3070
  • Disabled 'Hybrid Mode' under Lenovo Vantage

Benchmarks:

  • Time Spy - 5,753 [5686 GPU score] (dGPU) | 8,747 [9487 GPU score] (eGPU)
  • Firestrike Extreme - 6791 (dGPU) | 11,369 (eGPU)

Issues:

  • So far have only tested while playing AC Odyssey. And I feel I'm getting low framerates. It was only running at 30-40fps at Ultra High presets. Turning down the settings to Medium didn't help either, as I was only getting around 40fps (dGPU was getting 50-60fps)
  • Noticed on HWiNFO64 that the PCIe Link Speed of the eGPU is stuck at 2.5 G/Ts (not sure if this is normal, hope you could pitch in the normal values if ever)

Other Info:

  • Running Throttlestop at -145mv core & cache
  • Lenovo Vantage profile running at "Performance" mode
  • Max monitored PCH temps at 75 degrees

I'm not sure / confident if my scores are within the expected performance of an RTX 3070 eGPU. Would appreciate if someone can share how I can further optimize this.

Thanks!

You will not get lucky playing Games with the Anvil Engine - I guess this is a bandwidth issue.

You will get lucky with almost all other games however.

@phila-delphia, tested with other games as well, and experience was better vs when playing AC Odyssey:

  • CoD Modern Warfare (Multiplayer) - 60-70 fps, mostly high, RTX ON
  • Mortal Shell - 60-70 fps, Ultra settings
  • Witcher 3 - 50-60 fps Ultra Graphics (Hairworks Off) High Post Processing, 60-70 fps (can go up to 90fps depending on location) Very High Graphics (Hairworks Off) High Post Processing

Will continue testing with my other games and post results here

So just an update on my setup. I still think that its not performing properly. I'm not sure if its the 2.5 Gt/s PCIE Link Speed I'm getting or what Cry

Sharing the values i'm getting on CUDA Z, GPU Z, and HWiNFO64. Hope someone will be able to point out if something's amiss.

Thanks in advance!

If you put the "draw distance for leaves" down from "very high" to "high", you will get even mor FPS in Witcher 3 (bandwidthlimit)

As with any 8th/9th/10th core H the PCH is not built into the CPU directly which will result in an extra performance loss...

All the best

@styl_magnus, definitely something not right with your bandwidth, should be at least 2000. The enclosure may need a firmware upgrade.

Ran the Heaven Benchmark using the Extreme Preset. Mine's really performing subpar, as I didn't even hit your 3K score Cry

Sadly that seems to be the case... I think the 2.5GT/s PCIE link speed is the culprit. I already email Lenovo about it. Hopefully they can assist. Otherwise might end up selling the Mantiz at a discount, and prolly build a desktop to maximize my 3070 Cry
