Gaussian 16 supports a wide range of computational chemistry tasks, including:

Hardware‑specific optimized binaries exist for different CPU instruction sets, ranging from “legacy” (pre‑SSE4.2) to SSE4.2‑enabled, AVX‑enabled, and AVX2‑enabled builds. Using the correct build for your architecture can significantly boost performance.
