Default 64 bit
Is the 64 bit version of pc-bsd only for amd processors or can you use it with an intel i7.

Thanks

Hi,

also i386 Generations of CPU can running with AMD64. The Most intel since P4 will do it and the Most AMD since ... (i dont now exacly).

It's just the generic name for the 64-bit version. Whomever comes out
with it first tends to win the naming scheme. Hence, it was called i386
for many years

Hi matto,

the i386 is an synonym for the 'intel' CPU Architecture, that the Poster know its not ARM, Mips or Sparc, no, its intel ;-)

ahhh,
http://en.wikipedia.org/wiki/X86
http://en.wikipedia.org/wiki/X64

i386 = Pentium 3 using x86 architecture = 32bit math
intel i7 = intel i7 core using x64 architecture = 64bit math

Most 64bit math processors can do the 32bit math, so they are "backward compatible." So your intel i7, can do either way. Yes intel made first the x86 chips, so they are synonyms. AMD went ahead first to play with 64bit tech. Both now offer 64bit tech. So you are in the safe (most times) with buying new computers.

Difference? For the super-user that does heavy work, 64bit math does the work. 64bit programs? Not so many. Do I care? When 128bit exists, then we have flaming laptops.

not entirely true.

AMD64 is a extention to Intel's i386 arcitecture.
it's called AMD64 because AMD made it, but intel supports it too.

All Core-i processors support Intel EMT-64, which is intels implementation of AMD64.


technically, the software i not using a AMD64 acritecture but a i686 acritecture and a 64-bit processing extention.


also, x64 doesn't exist, it's called x86-64 since it's a extention to x86.


64-bit is a bit faster because it can use longer file names and it supports more then 3GB of RAM.
with 32-bit you can use up to 3GB of RAM or you need to use a PAE, but those slow down the system.

Thank you, and forgive me misinforming! I will remember that.

Default 64 bit
Thanks for clarifying my oversimplification, bebuxe. Also, nice writeups
on usage! We run several i386 and AMD64 PC-BSD workstations at work,
usually running AMD64 on the systems with over 4GB of RAM. I haven't
noticed a huge difference in general desktop, besides compiling, but
jnixson might have more to say on that.

Cheers!
