Did a really quick research on them and that’s basically what I found.All I know is what's shown...I think they're basically the same thing?
"Some comparison of the ".32 Automatic" as defined by SAAMI and the "7.65 Browning" as defined by CIP may be useful. Although some of the cartridge measurements differ by as much as 0.16mm, the names are considered to be synonymous. However, the maximum average pressure - as measured by a transducer on the test barrel - is 20,500 psi (1,410 bar) according to SAAMI, while CIP allows up to 1,600 bar (23,000 psi). This may explain why the cartridges from European manufacturers tend to chronograph at higher muzzle velocities compared to those from American manufacturers."
