US Laptop Shortage Could Derail Remote Learning:
As students and teachers prepare for a return to in-person learning for at least some of the time this fall, many of the nation's schools are facing shortages and delays for laptops and tablets needed for online learning, an Associated Press investigation revealed.
Lenovo, HP and Dell, the nation's largest computer companies, have informed school districts that they are short nearly five million laptops.
[...] Last month, at the request of President Donald Trump, the U.S. Department of Commerce imposed sanctions on 11 Chinese companies, including Lenovo, AP reported. School administrators have asked the Trump administration to devise a solution because remote learning without laptops is impossible.
Lenovo has informed school districts of the supply chain delays and the trade controls set by the Commerce Department, which would cause another slowdown. Lenovo declined to respond to an inquiry from AP.

What IPC did they have after the improvements?

I just poked around looking for that answer, and discovered that generally, IPC is measured in % improvement over an ever-shifting baseline. However, I did find actual numbers between 3.1 and 3.6 for some processors. There was also a vague reference to a theoretical maximum of 4.0, with current architecture (at the time of that article-Skylake can allegedly reach 5.0).
But in common numbers, the AMD Ryzen came with a 52% improvement in IPC over the previous, obsolete crap that was on the market before. And these days, 18% improvement is typical. NB this paragraph is entirely composed of useless, outdated, unsourced trivia. I include it to illustrate my frustration with IPC benchmarking.

I was scared by the concept of double-digit IPC improvements. Not that I've been following architectures for nearly a couple of decades since DEC was ruling the roost with their Alpha, and figures approaching 4 were the target back then.
