Literally everyone I've seen on this forum and youtube have the i9 + Vega 20 model. I went with a i7 + Vega 20 because i thought i9 might run too hot for the current design of MacBook Pro. Is this a bad combo and is the performance significantly inferior to the i9 + Vega 20 model?

You see mostly i9+Vega combos because that's what available for pick up at Apple store. If you want i7+vega you need to custom order. There has been about 1e5 threads about i9 vs i7, i9 can be up to 7% faster in single threaded workloads or short all core bursts (lasting few seconds), when fully loaded they're identical performance wise and they both can run as hot as it gets, both capable of easily overwhelming the Macbook cooling, or cooling of any other laptop that's not classified as a melee weapon.
 
I have the i7 & Vega 20 combo.

Cinebench: CPU 1090 (1083 after 5 runs) OpenGL 94.27 fps
Geekbench: Single-Core 5207 Multi-Core 24169

This thing flies, so don't worry about getting the i7 over the i9.

I went with the i7/32Gb/1Tb/Vega 20 and got similar results to the ones above. It is a great machine and I've yet to do anything where I wish I would've gone with the i9.

I don't think the OpenGL in Cinebench is showing the improvement of V20. I get 94 fps on my 2017 560, now the CPU test does show the improvements of 6 core. I get 760 for that.

There must be better tests for OpenGL?

The various Unigen benchmarks would be better tools to test GPU performance. I just mentioned the OpenGL score as it was in the attached image, but figured the OP was just interested in the CPU scores.

Is there any reason to get the Vega 16 at all?
I don’t see any. If you need GPU get Vega 20, if you don’t - get base with 555x and save yourself $550. Btw - you can again configure 2.2/555x with 2 and 4TB ssd, they took it away after Vega launched maxing out the base at 1TB.
 
How’s the fan noise on the i7 Vega 20? I’ve read the i9 model is quite noisy under load. Thanks
 
Also have exactly this configuration. Upgraded over my trusted original 2012 rMBP. The new machine is fast, silent, and cooler than my 2012 machine. It never stutters or struggles to do anything. And the GPU is way faster than I though it would be. Around 6x times faster in Aztec High (GFXBench Metal) than the GT 650M in the 2012 rMBP.

You were more lucky than me. I also was finally upgrading from my 2012 rMBP, but pulled a trigger a little earlier and ended up with the Radeon 560X. That was the only component I didn't like on my machine, alas there were no other options back in Sep.
 
I've noticed that those with the 32GB ram always seem to get higher GB results. I'd have liked to go for that option too, but here in Europe the Vega 20 MBP with a 1TB SSD, which is the very minimum I'd feel comfortable running with, already costs 4200 euros, including tax. That's a fair bit more than I would like to pay already, so 480 euros just for the extra 16GB of ram was an option too far for me.

It is a lovely albeit expensive laptop though. I even appreciate the keyboard and touch bar, even if it does take some getting used to. I often touch the bar by accident, perhaps that's the inspiration behind it's name ;-)
 
here's a question.. I have Radeon Pro 560x. the fans are loud on this machine.. too the point that on FaceTime, the person im on FaceTime complains that its to loud.. first MacBook that has this problem. is it better with Vega?
