The 2.3 seems to have something strange going on though. The distribution doesn't really overlap on the high end the way the 2.4s do. It really seems to me that the 2.4 behaves about as you'd expect under this theory, with a little bit more "mass" in the violin plot towards the bottom end, but with a higher median and similar peak. The 2.3s though are just lower, across the board.

Yeah, I lost my patience waiting for more benchmark data and just ordered the 2.4.
 
I suspect it has to do with Intel's binning? The chips that run the fastest and coolest become 9880HKs. If you fail that test, you might still have a career as a 9880H...
 
So I just installed the demo/trial of Geekbench 5 and run the regular CPU benchtest and got these results on the 2.3ghz version (with 32gb ram and 8gb videocard). Looks really high to me and even higher than most 2.4 results? Are these correct or did I do something wrong (I'm a newbie to this)

Did you install some MacOs update?

Perhaps you just won the chip binning lottery😅 Congrats!

Oh that's nice. That's my combination as well.

Yes, I'm running 10.15.1
Isn't the latest one 10.15.2 though?

Yep, your's are 5% higher then the average results of 2.4 Ghz model currently on Geekbench browser.
 
Interesting. @leman is it easy for you to redraw the graph with the RAM spec included?

I have now grabbed all 2019 15" and 16" scores (took a while since Geekbench browser is throttling requests — quite sensibly). I have also removed the lowest 5% of results (per group of model/CPU/RAM) in an attempt to weed out some of the underperforming outliers.

The regression analysis suggests that for multi-core Geekbench scores, 32GB models perform better than 16GB models by an average of ~600 points. No difference between 32GB and 64GB models. No effect of RAM on single-core benchmark scores. This is consistent across models (2019 15" or 16") and CPUs.

Comparing the 15" and 16"... according to my (very crappy and lazily set up) linear model the 16" is ~30 points slower on average than comparable 15" config in single core tests and ~150 points faster in multi-core.

If you want some graphs, here they are (I don't think that since-core is that interesting):

just a thought could the results for the 16 be lower since it is already working harder in the background to push higher resolution of the screen.
 
Really wish I could have done 32gb, but with the Adorama discounts on the base models ($270 on the i9), it would have been $670 for the upgrade from 16gb. Glad the i9 2.3 numbers have normalized at least.

@leman Could you share which 15 inch models are included in your graphs? I’ve heard few people say that CPUs on newer Vega models run better compared to models with Polaris GPUs. I guess Polaris GPUs may suck more power or run hotter.
