The latest market research from the Gartner group indicates that the market for PCs has experienced its "sharpest decline" since 2013. However, it seems this year-on-year drop in shipments, which applies to the first 3 months of this year (1Q2020), is related more to the Covid-19 pandemic rather than to demand for this category.

The problem is at least as far as laptops go is, most people own their laptop for 3-5 years, and there has been very little improvement.
Intel has been stuck on 14nm and with reliance on boostclocking and poor thermals the real world benefit was pretty much non-existent vs a 3 year old laptop
Nvidia delayed their super, so anyone who had a 3 year old laptop would have only seen marginal improvements.
AMD's Zen 2 was only out end of March and only 1 or 2 laptops?
Considering the new cpus/gpus right around the corner, 2020 Q1 wasn't a good time to buy a laptop.
without considering COVID, there is but one reason.
Anyone in their minds who was ever going to buy a new PC already did and it's a Ryzen system. Now with 6-12+ cores in our systems and decent IPC across the board, there is zero reasons to buy a new and modern PC.
You'll see a few people upgrade to Ryzen 4k series, but I don't think there is a slew of people waiting for 4k to finally buy a PC.
