x86 be like...

Intel: In HPC, use streaming loads and stores for non-temporal data you only use once.
Users: What does "streaming" mean? The CPU is not really "streaming" anything.
Intel: Oh, this feature is called "streaming loads and stores" because it's provided by the "Streaming SIMD Extention" (SSE)!
Users: And what does SIMD have anything to do with data streaming?
Intel: Because it was originally called Internet Streaming SIMD Extensions. The fact that MOVNTDQ increases the memory STREAM benchmark score is a coincidence.
