What this memory is

4 GB of DDR4 as one stick, rated at 2133 MT/s.

Size
A small amount: fine as an upgrade, not for a new PC on its own.
Sticks
One stick runs in single channel, which is slower in games. Two matching sticks are better.
Speed
Slow for a gaming PC; 3200 or more is better.
Getting the full speed
Switch on XMP (DOCP on some AMD boards) in the BIOS; without it the memory runs at a slower default speed.
DDR4 vs DDR5
They have different notches, so a board takes one type only.
