Hi Bill and all,
The technology we will use is called AVX and that is present on all
Intel CPUs branded Core i3/i5/i7/i9 (circa 2010 to present), it is
also present on AMD CPUs since the Jaguar or Puma based CPU models
(some late Athlon-II CPUs, all Zen based CPUs, including Ryzen) circa
2013 to present.
None of the computers I'm using to run WSJT-X has the AVX extensions.
In my opinion, the planed performance enhancements with AVX should be
optional and not mandatory. Perhaps a compile time option.
Best wishes,

Claude,
we have no intention of supporting multiple version of WSJT-X (and
MAP65) for different CPU instruction sets, any optimization using AVX
will be selected automatically at runtime based on availability, and
other than resulting speed differences will be invisible to the user.
