Thanks for the response.
However, I'm unable to see AVX mentioned under the Core I3-370M
processor column in the attachment.
The second column which does include AVX is for a different
processor - Core I7-2600.
I extracted the data on the two processors I use for wsjt-x, the
I3 is in the shack laptop and the I7 is in a desktop in another
building, which I often use to run wsjt-x remotely by piping the
audio to and from the shack laptop over the lan.
I'd be happy if the laptop I3 does support AVX but i don't think

that's not correct, the information
that your CPU supports AVX is right there in the screen capture

I'm currently running an Intel Core I3-370M processor, which
apparently does not support AVX (see attached under
Instruction Set Extensions)

all WSJT-X users,
we are looking into some performance enhancements that will
take advantage of some parallel processing features of modern
CPU architectures. In order to gauge how much backwards
compatibility for older CPUs we will have to implement it
would help to know who is using such older processors. Please
don't turn this thread in to a mine is better than yours
conversation, all I need to know is who or how many of you are
using the older CPU architectures. Note that this applies to
MS Windows, Intel Linux, and Intel macOS users, it is about
CPUs not operating systems.
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.
Notably Intel CPUs branded Celeron, Pentium, or Atom do not
support the AVX technology.
So in summary, look up your CPU and if it **does not support
then let me know.
