This is an update of my previous setup, you can find it here:

https://egpu.io/forums/builds/2020-acer-15-predator-triton-500-rtx-2060-rtx-3070-32gbps-tb3-sonnet-breakaway-550-win10/

I changed the Laptop from Acer Triton 500 to a Razer Book 13, keeping the Zotac RTX 3070

The thermal performance of the Triton 500 decreased notably over the months. It got pretty hot pretty fast (despite dust-cleaning and CPU uV).
The problem according to sensors was the cooling area around the internal RTX 2060: even with the dGPU inactive, the Laptop's GPU area heated up to 80 degrees. I had to put both of Acers graphics-card fans to around 4000+ rpm to bring thermals ~70 degrees. The i7-9750 was constantly around 90 degrees which also seemed too high (the Acer Predator Sense is actually a nice tool to play around but that was a small feat).

To make a long story short: the noise of the Laptop started to bother me and CPU-throttling obviously became an issue.
Because the 3070 is literally silent in the Breakaway Box (see original review) I gave the Razer Book a chance hearing of the new efficient Tiger Lakes and the availability of 2 x Thunderbolt 4.

The result is pretty impressive in that regards that I have a slightly better performance at drastically reduced noise and thermals. The Razer Book is silent without any uV.  The 2 fans of the i7-1165G7 do not even bother to wake up on Prime Stress Test and the 3070@Sonnet is as quiet as before.

Some additional objectives:

  • Timespy Graphics performance now is ~200 points higher vs. the old setup although its the same graphics card AND Timepsy CPU score is lower. My only guestimate is
    either the super-fast RAM of the Razer or the TB4 interface give the graphics card a boost
  • uV is not possible with Tiger Lake at least not through Throttlestop. However, I am not sure if this is required: After 3:30 h of 3D-Gaming the i7-1165G7 averages 60 degrees @ 3666 Mhz average clock speed (according to HWinfo); the 3070 btw averages a mere 55 degrees (1500 Mhz Clock average)
  • Obviously, there are performance reserves through oc'ing or uV the 3070 but currently I see no need

In sum, it's a clear upgrade from a noisy to a silent eGPU setup. The main downside (while using an external display) is the reduced connectivity of the 13" Razer vs. the 15" Acer which in this case I take as a tradeoff. The Razer Docking station can solve this problem but at a whopping 350 EUR it might not be everybody's choice.

@largo_embargo, Thanks for you post. I'm considering getting the Razer Book and a egpu for gaming. What was your TimeSpy score with the Razer Book? I'm looking at the Gigabtye Aurous Gaming Box with a GeForce RTX 3080 Ti. My hope is to be able to get over 80FPS in AAA titles like Call of Duty and Battlefield. Do you think that's reasonable with the CPU being the bottleneck?

 

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