I expect they are referring to the "Vector API" described in JEP 426: Vector API [1]. From the summary:

    Introduce an API to express vector computations that reliably compile at runtime to optimal vector instructions on supported CPU architectures, thus achieving performance superior to equivalent scalar computations.

Yes. Where does it expose the AVX or ARM intrinsics? I only see generic add/neg/mul methods (thus the comparison to .NET Vector<T>) and not the intrinsics exposed thhemselves; here is a random pick from the .NET ones: https://learn.microsoft.com/en-us/dotnet/api/system.runtime....*)
