On the official sit where you have to choose a cpu to download the wallet there are many models missing.
In fact, all those earlier intel core i5/i7 like sandy bridge that support avx but not avx2
As a result, that wallet version is never recommended for download and users are force to choose standard instead
The standard version is for non-avx2 CPU's.
If you select any of the CPU's in the list, the AVX2 version is shown.
This is correct.
(Go and try running the AVX2 version on a non-AVX2 CPU, report back your findings)
That's not what I meant.
There exists a version for avx1 on GitHub. This should be the recommended for sandy/ivy bridge and perhaps earlier core i5/i7 (but not core 2 duo/quad)
But such processors are not on the list so the avx1 version is never offered for download.
Is that the case for a reason? Why not add those cpus in the list?
