It's hard to make that claim. There's something bizarre about the GB4 results listed, since they list latency in "Moperations/sec" rather than the more usual "nanoseconds"!
I don't know exactly whats fscked up, but at the very least the memory latency number is meaningless, and possibly the rest of the (many many many) submissions are somewhat dubious.

By jumping a few pages down I did find
https://browser.geekbench.com/v4/cpu/10502053
which shows a realistic latency number --- slightly worse than the A10:
https://browser.geekbench.com/v4/cpu/compare/10685412?baseline=10502053

But now this time round the weirdness seems to be in the memory bandwidth, which has a bizarrely bad gap between the "Copy" number (matches Apple) and the "Bandwidth" number (substantially better than what even the iPhone XS delivers).

Overall it looks like a reasonable match to an A10. Fewer resources available for crypto (AES) and dense linear algebra (SGEMM), worse indirect branch prediction (Lua -- maybe TAGE for branches, but not VTAGE for indirect? or much fewer VTAGE resources?). Of course, no surprise, more cores, but not great multi-core scaling, worse than what Apple sees for the A12X.
I wouldn't call it a rousing triumph for DynamIQ, though that may represent a lazy/rushed implementation more than anything else.
