SVE2 does not increase the maximum speed. That depends only on the width and number of the ALUs, on the number of cores and on the clock frequency.

The purpose of SVE2 is to simplify the writing of the software that exploits the data parallelism, both when that is done manually and when that is done automatically by an autovectorizing compiler.

With SVE2 it should become much easier to deal with data structures where the sizes and the alignments are not multiples of the ALU width and it will also no longer be necessary to write many alternative code paths, to take advantage of any future better CPUs, like when optimizing for Intel SSE/AVX/AVX2/AVX-512.

There are still a majority of programs that do not utilize as frequently as possible the existing SIMD units. With SVE2, their number should diminish.
