I tested under xmonad on a
cpu0: Intel(R) Core(TM) i7-10610U CPU @ 1.80GHz, 7095.28 MHz, 06-8e-0c
inteldrm0: msi, COMETLAKE, gen 9
inteldrm0: 3840x2160, 32bpp

I watched http://youtu.be/eXjRcfw9CPQ video and scrolled the page back
and forth. It played OK at 1440 and constantly rebuffered at 2160. The
audio was smooth with some occasional clicks even though the video was a
bit jerky.

I saw all 4 cpus running some user time (<50%) with typical top(1)
output being something like this:

PID USERNAME PRI NICE SIZE RES STATE WAIT TIME CPU COMMAND
18037 greg 10 0 834M 893M onproc/2 fsleep 31:13 129.25% chrome
86660 greg 46 0 222M 386M run/0 - 5:10 21.92% chrome
94707 greg 10 0 182M 75M onproc/2 fsleep 6:49 18.65% chrome
91124 greg 2 0 313M 247M sleep/2 poll 2:40 6.05% chrome

I guess your machine is too slow for what chromium is doing. They run a
bunch of different processes so having more cores should help.
