This is a somewhat low-level question. In x86 assembly there are two SSE instructions:

MOVDQA xmmi, m128

and

MOVNTDQA xmmi, m128

The IA-32 Software Developer's Manual says that the NT in MOVNTDQA stands for Non-Temporal, and that otherwise it's the same as MOVDQA.

My question is, what does Non-Temporal mean?
