Depends on the ARM processor and which x86 CPU to compare with. For example, a high end ARM CPU translating x86 code could compare well against an Intel Atom.

Okay, follow up then: Given a high-end arm chip, what would be a comparable intel x86 chip with similar performance, without either chip using any emulation? Is there a high-end ARM chip you could recommend I lookup and find benchmarks on something like Geek Bench?

  Emulation performance can vary drastically depending on the application. Some programs might run with unnoticeable penalties, while others run dreadfully. It's not just about having a suitable CPU though, it also relies on a good software layer. And there are many factors such as whether you're hitting cache or not. Here's how the Windows x86 translator on a Qualcomm Snapdragon compares to Intel CPUs https://www.techspot.com/review/1599-windows-on-arm-performance/page2.html https://www.techspot.com/review/1599-windows-on-arm-performa... From what I've seen online so far, the binary translator from Apple, Rosetta 2, seems to have promising technology. But we won't know until we see the new Apple Silicon based Macbooks.

This sound as a huge penalty since running code on iPad Pro is faster than on Core i7 2.9 GHz.

  My daughter has a 1-year old iPad mini. My own modest gaming rig has a mid-range 2-year old i7 (and an SSD & 1050 ti video) Geekbench results for single-core performance are pretty much identical, though I win out by a wide margin on multi-core and video benchmarks. But forget about benchmarks, here's a more practical example: fortnight loads in about 15 seconds on the ipad. For me about 45. It's possible the graphics are lower quality on the ipad, though I can't tell the difference. Or maybe they have to optimize a lot more for iPads. Fortnight updates on the iPad, after downloading, also takes minutes while mine takes about an hour. I look forward to much less expensive arm chips coupled with a dedicate GPU, especially if it drives developers to write more optimized code. In fact, this fortnight difference might be a case study in just how much can be achieved by optimizing. 3-5 year old phones can run Fortnite.
