MOVNTI

Moves a dword from a register to a memory destination using a non-temporal store, bypassing the cache hierarchy to avoid cache pollution.

The following table covers the supported source and destinations:

DO NOT support LOCK

This instruction is only available in 32-bit mode or when the processor is operating in compatibility mode. It SHALL NOT be used in 64-bit mode; for 64-bit operations, MOVNTI is replaced by MOVNTDQ or MOVNTPD.

The store is weakly ordered. To ensure the data is visible to other processors or devices, a memory fence instruction (such as SFENCE) MUST be executed. Failure to use a fence may result in the processor committing the write to memory after subsequent instructions have executed.
