Yes. The terms used vary between processors, but the function is the same.

The next slower alternative is write-through (ie. no delayed writes), then
no-cache (or cache-inhibited) and last no-cache/serialized (called
"cache-inhibited/precise exception model" on the 060 - which only makes
sense for IO areas).
