That was about as expected. Going to 128 cores for cache-resident compute workloads helps, it hurts for anything else. That is a seriously cache starved chip... only 16MB SLC?
Even with 1MB of L2... that's still a cache starved chip. The new iPhone has almost as much cache on it!
That said, I would absolutely love some sort of mid-range ARM desktop (that isn't Apple). There are the "small workstation" class ARM boxes (quite a few thousand dollars, 64 cores or so), there are the various small board ARM computers (4-6 cores, $100), and... there's really nothing in the middle.
Give me 4 X2 cores, a cluster of A74s clocked hard, and put it in a NUC type case with at least 16GB of RAM, preferably more, and some NVMe.
