ankushg Posted August 26, 2009 Share Posted August 26, 2009 Some info on 64 bit and 32 bit http://blogs.zdnet.com/Apple/?p=4712 That's an interesting read... I have a question though: It's pretty apparent that current Leopard kexts wont work with 64-bit Snow Leopard, but what about on 32-bit SL? I have only 2GB of RAM and not all of my controllers are fully 64-bit compliant so I'm probably going to go with 32-bit, but I just want to check if existing Leopard kexts will work in 32-bit SL. Thanks. Link to comment Share on other sites More sharing options...

Angel Bunny Posted August 26, 2009 Share Posted August 26, 2009 Running benchmarks it looks like 64bit is slower in almost every way just slightly. My guess is apple chose 32bit as default for speed related reasons since the 32 bit kernel can use more than 4GB of ram fine and has really no limitations. the only difference is the 64bit kernel can access more registers but has a larger stack size. Since the kernel doesn't need the extra registers (the speed increase part) and will be forced to use a larger stack size (slow down) it would be better to keep the 32bit version as default.

curlyboy Posted August 26, 2009 Author Share Posted August 26, 2009 Unless people have a bucket load off memory i dont see the point in the average user worrying about 64 bit tbh , Same as it is in windows if you dont have a lot off memory 64 bit doesnt matter Link to comment Share on other sites More sharing options...
