Replacing select condition with jq's `IN`

Given the simplified input:

[  [ "gpu" ],  [ "disk" ]]

I would like to select the arrays for which the first element is "gpu".

I can do it with a simple condition:

map(select(.[0] == "gpu"))

[  [ "gpu" ]]

But I don't understand what's wrong when I try to use the IN builtin instead:

map(select(.[0] | IN(["gpu"])))

[]

I'm using jq 1.6
