− | In Skylake, {{x86|AVX2}} has been entirely power-gated. The motive for this change is derived from the fact that applications either make heavy use of AVX2 instructions or don't use it at all. Most programs seldomly use AVX2 for only a small number of instructions. This gave Intel the ability to completely power gate it when the core execute code that does not make use of those instructions. Skylake requires a warm-up time before instructions can execute at full rate | + | In Skylake, {{x86|AVX2}} has been entirely power-gated.

Most programs seldomly use AVX2 for only a small number of instructions. This gave Intel the ability to completely power gate it when the core execute code that does not make use of those instructions. Skylake requires a warm-up time before instructions can execute at full rate. Executing a dummy AVX2 instruction some time prior to heavy AVX2 workloads to prepare the CPU can avoid this. |
