Advanced Performance Extensions (APX) expand the entire x86 instruction set with access to more registers and adds various new features that improve general-purpose performance.
Intel is extending its instruction set. "Intel® APX doubles the number of general-purpose registers (GPRs) from 16 to 32. This allows the compiler to keep more values in registers; as a result, APX-compiled code contains 10% fewer loads and more than 20% fewer stores than the same code compiled for an Intel® 64 baseline.2 Register accesses are not only faster, but they also consume significantly less dynamic power than complex load and store operations."

Intel AVX10 includes all the capabilities and features of the Intel AVX-512 ISA, both for processors that feature 256-bit maximum vector register sizes, as well as for processors thatfeature 512-bit vector registers.
Both seem to be a pretty sizable deal.
