Amazon's homegrown 2.3GHz 64-bit Graviton processor was very nearly an AMD Arm CPU

SciMark is inherently a single threaded benchmark, so it really measures single core performance, which would make sense given 2x performance with 1.5x clock speed and an architectural bump.

Once you factor in the four times core count, it will be much more useful in a datacentre environment with real-world workloads.

It's interesting that it's a non-NUMA design. This normally causes memory bus contention issues with multi-core designs, so I wonder what they've done to allow 16 cores to access the same memory without blocking.
