Were I to guess

> The biggest cores on the the Xring O3 are the C1-Ultra. C1-Ultra really powerful cores. They support SME2 (Scalable Matrix Extension 2) for matrix/AI acceleration, SVE2 for data parallelism (SIMD).

This is where the magic is happening (I believe). They have these ultra cores with additional extensions which they are pinning the benchmarks to.

Realistically, that sort of thing isn't useful as non-homogeneous architectures really suck for an application or OS to deal with.
