first off..sorry if this is a dumb question ..i really tried to find these answers but had no luck searching..

i have a question about the processor in the title.

my computer is a hp pavillion a450n

i was wondering if first is this a dual core processor?
when i look in system info it shows two processors.

also..is this processor compatable to use ubuntu 64 bit..or do i have to use the x86 version 32bit. i heard that the 64 bit version runs a little better thats the only reason i ask..i currently have gutsy x86..but wanted to use the new edition 64 bit but didnt know if i could..here is my computer info from terminal..it too shows two processors...

is this cpu a dual core cpu???? well to the software it is as it has hypertreading turned on.

but the physical internals of the cpu is a single core cpu.

hyperthreading has been made pretty much obsolete by dual core cpus.


hope this helps

it is a 32 bit cpu

You have a 32-bit CPU with Hyperthreading (which the OS interprets as dual-core)

so does that mean that i can use the 64 bit os...or do i have to stick with 32 bit...

You have to stick with 32bit Ubuntu. Which I actually prefer.

I have been searching online to verify the bit type of mine as well, and am getting confused. Most places say that Pentium 4 is all 32-bit...minus the last one or two versions. On a linux forum, they said that if "lm" is the Flags section, it is 64-bit. Is this true?

This thread is likely to get closed as it's very old, and bumping such old threads is discouraged here. So, you may be better off starting a new post.

That being said, it is true that the 'lm' flag is an indicator of 64-bit architecture. You can also run the following to see the supported operating modes:

It did help, thank you. I am a novice at non-Windows OS, so Google has become my friend/enemy here.
