Gracemont cores of Intel Alder Lake processors will support AVX, AVX2 and AVX-VNNI instructions
Intel processors often add quite innovative technologies before competitive solutions. These additional features are often highly valued in the industry and are therefore widely accepted for certain applications. Intel Gracemont cores, which will come to the market in the future, support AVX, AVX2 and AVX-VNNI instructions. These instruction sets are intended for a variety of high-performance workloads.
Recently from the company they have updated the documentation of extensions of their processors. Extensions and Future Features Programming talks about the type of instructions that your next architectures will support. Within this roadmap are Alder Lake processors, which implement enhancements for software developers.

Intel Gracemont will support AVX, AVX2 and AVX-VNNI instructions
These new Alder Lake processors are processors with two types of cores inside. First we have the high-performance Golden Cove cores and then the low-power Gracemont. Thus we have a combination of nuclei that is very reminiscent of the big.LITTLE structure. For these processors, a hybrid technology has been developed that allows efficient switching between cores.
Alder Lake has against it that it will not support AVX-512 instructions, which will be a problem. Gracemont cores will not be able to receive certain workloads from Golden Cove cores when AVX-512 instructions are executed. Of course, the Alder Lake processors will support AVX, AVX-VNNI, AVX2 and UMONITOR / UMWAIT / TPAUSE instructions.
Intel's AVX-512 instructions are highly rated for being high-powered, although with limited support at the moment. Adding support for chips with low-power cores is pointless. 256-bit AVX instructions are widespread, hence Intel supports them on the Gracemont architecture. Note that Intel has not detailed about the support of AVX / AVX2 in its processors with Gracemont cores.
Supporting AVX on Gracemont kernels makes the task much more efficient than running it on Golden Cove kernels. We don't know if supporting AVX / AVX2 will directly impact Gracemont's consumption relative to Tremont.
