Real world? AFAIK no not yet. The issue is that traditional benchmarks don't really tell the whole story. IPC isn't directly comparable because ARM is ostensibly RISC (this is debatable I'm aware) and Intel is CISC (also debatable). So until things like Adobe Premiere or Media Encoder are ported over (if they are), or similar real world workloads like Blender, it's going to be really hard to compare. Even then things like design power matter. A 15w Intel chip is likely to outperform a 5w ARM chip just because it has more headroom thermally. It doesn't mean that either is faster (IPC per watt goes up the more you downclock for a variety of reasons).
If this sounds like I'm saying it's apples (no pun intended) to oranges... that's pretty much the case. Apple is likey not going to produce an ARM chip in directly comparable fashion to an Intel chip. E.g. equal cache, memory bandwidth, TDP (using Intel calc method), PCI-e lanes etc. Mostly because it doesn't make sense to do so because Intel's chips are designed to be a component of the system while ARM chips are largely designed to be an SOC.
