It's probably worth mentioning at at least SOME point that the Intel CPU's you're comparing this machine to are notably more expensive 6-core/12-thread i7's (the i7-8750H to be specific), which isn't a particularly fair comparison when the much cheaper AMD Ryzen 7 3750H part in question has only 4-cores/8-threads (this is backed up by their respective TDP values as well, with the bigger Intel CPU's being rated for 45W vs AMD's 35W).
Compare it instead against it's ACTUAL Intel competition in the also 4c/8t i5-8300H though, & the Ryzen 7 3750H's "productivity deficit" drops to a by & large unnoticeable ≈5% (for example, in Cinebench R15, the R7 scores about 730-780ish whereas the i5 lands around the 780-820ish mark), and even the newer (slightly higher clocked) i5-9300H is still only about ≈10% faster. And if you compare it to the similarly priced (rather than specced) 4c/4t i3's instead (ala the i3-8100H), then Ryzen comes out with a clear victory.
Comparing CPU's in a vacuum without acknowledging price & thread count differences does a disservice to both the reviewer/article writer and the reader.
