Hi Alejandro,
so there is no way to give me back the "lost" memory. Is it possible
that another motherboard might help?
AFAIK, No. AMD and Intel will always do the same thing until we all move to
real IA64.
Can you tell me the main differences between IA64 and x86_64 (Opteron)
IA64 is itanium - there are a lot of differences but the principle one for
your perspective is that you don't want to run x86 code on a itanium, it
has an x86 instruction decoder but you wouldn't want to use it if you
could avoid it.
? because in your one of the previous mail you said IA64 != EM64T and
emt64 getts lumped with amd64 collectivly x86_64. fundamentaly intels
implementation is compatible with amd's
its true, but I know is EM64T/AMD64 in 64-bit mode != IA32 but you
said that too EM64T is not really 64-bit, its a IA32 .. Can you give
It is ia32 except with 40 bits of real memory and 48 bits of virtual
memory and 64 bit registers.
one article that's use for getting a start on the instruction set is here:
http://arstechnica.com/cpu/03q1/x86-64/x86-64-1.html
me some link which just tells the difference between IA64 (Itanium)
and AMD64 (Opteron) ?
you're not likely to care about ia64, so I think what your'e really
interested in is ia32 vs x86_64 and intel vs amd in the context of x86_64
While googling I found this article
http://www.eweek.com/article2/0,1895,1046390,00.asp but its not
clearing mentioning the difference between Opteron and Itanium !
Although I found this difference in that article :
With the Itanium, Intel proposes to examine
programs when they are compiled into their executable form and encode
concurrent operations ahead of time. Intel calls this approach EPIC,
for Explicitly Parallel Instruction Computing, and it is the genuine
difference between the Itanium and AMD's x86-64. EPIC's drawback is
that the core of the Itanium no longer offers an effective
upward-compatible path to existing x86 code; its speed in running that
32-bit code has proved to be disappointing.
So is there any other difference except above ?
