This is not really true, the difference is much smaller and you will not boot windows 10 with the i386 feature set. Since Windows 8 the NX bit is required, making it require relatively modern CPU's, mostly x86_64, allthough a few x86 has it as well. So for example, you can run the 32bit version of win 10 on the 32bit Core Duo (it has nx), while OSX with its 64bit requirement needs a Core 2 Duo. Newer OSX require a graphics card of DX10 level, Windows 10 require DX9 level.
