You may have better insights from doing your own runs on your own systems.
Here's a sample from a recent run. Mostly small improvements and a few small 
negatives.

Benchmark                       Linux aarch64 | Linux x64 | MacOSX aarch64 | 
MacOSX x64

newStringFromCharsMixedBegin-size:64 |  1.22% |  0.91%    | -0.81%         |  
1.08%
newStringFromCharsMixedBegin-size:7  |  4.40% |  0.26%    | -1.88%         |  
4.60%
