PassMark CPU Bench Single-Threaded Perf Chart just seems wrong

[themanuel]

The subject chart is often recommended as a resource when deciding what processor to buy for emulation.

However, the results don't make sense to me whatsoever:

Processor                                                        Score
Intel Core i7-8565U @ 1.80GHz                         2378
Intel Core i3-8350K @ 4.00GHz                         2336

If this truly represents single threaded operation, how can the i7 have the same performance as the i3, which is running at more than twice the clock speed?

It just doesn't add up and makes me question using this chart when considering my next upgrade.  You could argue that the i7 has a larger cache, supports more instruction sets, etc., but non of that can make up for the enormous difference in clock speed.

The only possible explanation would be if the chart represents operation on a single thread but on all available cores, or if the results are normalized for clock speed.  However, I don't see that stated anywhere on the page.

Can anybody shed some light on this?

Edit:
Well, after clicking on that i7 CPU I learned that it has turbo speed up to 4.6GHz, which probably explains the discrepancy. It also has only 4 cores, just like the i3-8350K.
I guess this answers my question but feel free to weigh in if you have additional insight.
