Icelake with integrated TB3 controllers completely crushes non-Icelake CPU's with external controllers in performance (up to 40% gains...)
@james_knight, the 1185 is most likely the better eGPU option and the better laptop option. But if you are interested in sheer CPU power you probably want the 10850, which is a 45w TDP v 15w TDP chip. The 10th gen h CPUs are really not much different from the 9th gen, whereas 11th gen should be a real step up.
Thank you for the feedback and moving my post.
The issue that I am having is that when gaming my present setup is CPU bound. Both due to TDP and boost timer.
This is where my predicament lies. I thought 10th 6c/6t would be able to throw more at it (higher TDP). Yet the 11th 4c/4t would have the advantages of TB4 (low latency) and the higher single core performance.
This is why I was looking for hands on benchmarks. I've seen tests with the 11th 116, and seen posts with certain users looking to use the 10th Gen, but no stats for the 10th gen.
I've also just noticed on your build summary that you have a similar build to what I am running (exception I'm have an 8th Gen CPU).
Did you post your performance stats and also what 10th Gen CPU are you running in your Lenovo?
My build link should have my most recent benchmarks.
I didn't see any good comparisons for a 6 core 10th gen but since there is not a huge difference 9-10 you can look at itsage's build here with a 2080ti: https://egpu.io/forums/builds/2019-16-macbook-pro-rp5300m-9th6ch-rtx-2080-ti-32gbps-tb3-gaming-box-win10-1903-itsage/
That is about what you should expect.
I didn't run all the same benchmarks but my best Valley score is a little better than his score in that thread and my superposition is also about the same.
Which is to say I think it will be a wash performance wise between your two options. What you make up for in CPU power will potentially be lost in losing integrated thunderbolt and 10nm v 14nm process. Plus the 10th gen will be a lot more power hungry.
Meanwhile the 11th gen even at 4 cores is still a pretty decent step up from 10th gen. Faster single core and multi core clock speeds, and a pretty darn good iGPU.
@james_knight, I would not recommend the 10th gen H-CPU laptop if you plan on using an eGPU. With the exception of MacBook Pro and Alienware, we've found all H-CPU laptops (8th-10th gen) to have very bad Thunderbolt optimization. Either wait for 11th gen H-CPU with integrated Thunderbolt controller or go with the Evo platform.
I've tried a handful of laptops with integrated Thunderbolt controllers and they have been excellent in terms of eGPU performance. As long as the laptop has a good cooling system, it should work very well with an eGPU. My latest test unit is an ASUS ZenBook Duo UX482 (i7-1165G7).
@james_knight, My build link may provide some insight with a 10th gen H series chip hooked up to an eGPU. As @itsage stated, heat is a problem - unless you turn off intel's turbo boost when under heavy load to mitigate high temps. With my 3070 and 10750H there hasn't been much I haven't been able to do as far as being limited by performance. If I were to go back with the knowledge I now have, I would have gotten a cheaper laptop with an 11th gen CPU with no dGPU, as this would have been a more cost effective setup and would also perform better.
I appreciate all the advice and your time to respond.
Although heat should not be an issue as I have performed extreme heat tweaks in the past that prevented my current 8th gen CPU from exceeding 50 degrees. I hit the limitation of TDP with no way to circumvent. Yet part of me does not really want to go down the route again. It was merely for testing purposes and not sensible as a permanent solution.
11th Gen has more compelling arguments. So 11th Gen it will be.
Thank you all again.
