Just wondering if anyone has compared the two.

It seems that Ice Lake has better TB3 integration but Comet Lake benefits from having 6-core.

Not sure how this translates into eGPU/gaming performance.  Has anyone done any tests comparing the two?  Specifically 25W ice lake vs 25W comet lake?

@irev210 Due to TBT integration to the Ice Lake CPU, the Thunderbolt 3 connection should be better than previous gen (TBT through PCH). While I have not tested one myself I heard good results from eGPU vendors. It would come down to the laptop’s cooling system.

This is what makes it a very interesting comparison.  For example, the Dell XPS 13 7390 2 in 1 vs standard xps 13 both offer 25W TDP in performance mode.  Which one is better for eGPU gaming?  It would be great to see someone compare or if two people have similar configs to compare eGPU performance.

One of the more interesting laptops to hit the market is the MSI Prestige 14.  It is Hexacore Comet Lake plus Nvidia 1650 max Q in a sub-3 pound package with TB3.  From what I’ve read, MSI allows for significant CPU performance (up to 30 watt) meaning it has serious potential to be a good laptop+eGPU setup.  I just wonder if the Dell Ice Lake 7390 2-in-1 is a better experience .

@irev210 Yes the MSI Prestige 14 and 15 with the 6-core processor is an interesting choice. I put together an i7-10710U build recently (MSI Prestige 15 + AKiTiO Node Pro + GTX 1080 Ti). Its cooling system is to handle both CPU and dGPU so during eGPU use, it’s an easy task keeping only CPU cool. This laptop also has two NVMe M.2 slots so I’ll try M.2 eGPU adapter with it soon.

Interesting results, although without more data points it is tough to ascribe the performance difference to icelake's integration exclusively.  Would be nice to compare another U-class laptop, many of the 45 H based laptops don't have any cooling on the PCH which can substantially cripple TB3 performance under load, not sure if this is the case with the GS65 or not.

These results confirm that Coffee Lake “H” CPUs on PCs have performance issues as we’ve discovered here. Namely PCH throttling and some other missing optimizations. 

We need a older “U” CPU without integrated TB3 versus Ice Lake “U” CPU with integrated TB3 comparison to see if integrating the TB3 controller yields any performance gains.

At the end of the blog post, that person did mention:

One thing to note is that I WILL update this blog with eGPU results from Comet Lake after I complete my review of the MSI Prestige 14. Target is Mid-December, just before the holidays.

 

I'd imagine that the 2 extra cores + faster clocks on comet lake will absolutely pounce ice lake despite not having on-die TB3.  I'd just love to see benchmarks to confirm this.

It depends on if the CPU or GPU is the limiting factor. If these gains in that post are accurate relative to other U-class CPUs, then ice lake could be a good choice for those with a mid-range GPU that won't be bottlenecked by a reasonably fast quad-core, hyperthreaded cpu. But of course the CPU vs GPU load varies by application and game so it could depend. Definitely will be looking for those benchmarks when they come out.

I just received my new MSI Prestige 14 A10SC laptop (with a Comet Lake 10710u CPU), to replace my XPS 13 9370. I use a Razer Core X enclosure, and I have a GTX 1080 and a 5700xt. I'm very interested in testing the potential better integration of thunderbolt in Comet Lake, any idea how to proceed? Just classic benchmark comparison on différents games and benchmarks?

@kisscoool18 super interested in your findings, once you have, err found them.... I'd be more interested in real world benchmarks personally as synthetic ones are often meaningless to me and from what I have read and experienced actual real world performance differs in regards to performance loss via TB3 (which I think is one of the main issues these new CPU's may help fix).

I will fill this document during the next fews days, and come back here with a conclusion.

I just reallised this morning that the Thunderbolt controler is NOT integrated on Comet Lake, unlike the Ice Lake CPUs, which may remove quite of the interest regarding better TB3 support I guess.

thats a bloody comprehensive doc... look forward to seeing the results... Intel CPU's are getting confusing these days with constant iterative releases, so Ice Lake is what we are after...  a quick Google tells me the overly dramatic wind bags that are "Youtubers" are confused too, to what extent is hard to gauge due to the fact they are mainly clowns.

Any updates?  That doc seems to show there have been some issues?

I'm still testing and filling it. I've been quite disappointed with the AMD 5700xt, which is a great card but it seems drivers are not yet mature enough for eGPU, as I experienced issues and performances on several games are bad (while on others it's very good). So I decided to sell it and get a 1080 Ti instead.

I am hunting for Ice Lake H2D benchmarks. If you have an Ice Lake eGPU setup, grab CUDA-Z please and screenshot the performance tab:

Sorry but I returned the Ice Lake laptop, and I didn't had a Nvidia GPU at the time...
