I have a hp-compaq notebook with AMD Turion 64 processor with 800 mhz speed and 512 kb L2 cache.

Is this an i686 processor capable of running ubuntu 10.10 (Maverick Meerkat) os?

Found this excellent description on another site:

To give a little more information on that, the X86 processors started with the Intel 8086 processor way back in 1978. They were incrementally improved (80186, 80286) and then Intel released the Intel 386 (i386) in 1980. That was then followed by he 486 (i486), the Pentium (i586), and the Pentium 3/4 (i686) and AMD's Athlon/Duron/T-bird (also i686).

Since all these processors were based on the same architecture (basically they read/wrote 1's and 0's in the same way), and their names all contained "86", the whole family was collectively called "X86". All the X86 processors were 32-bit.

The recent trend has been to move toward 64-bit processors, and several different architectures popped up. DEC's Alpha and Motorola's PPC chips have been 64-bit for a while, but Intel's Itanium and Xeon and AMD's Athlon64 are the new kids on the block.

The difference between the Itanium and PPC versus the Athlon64 is that the Itanium and PPC have completely different architectures (they speak different 1 and 0 languages), whereas the Athlon64 speaks the same language as the 32-bit X86 processors, but adds 64-bit registers. Therefore the name of the Athlon64 in generic terms is "X86_64".

Intel, not to be outdone, has since redesigned its 64-bit Xeon processors to use the same kind of architecture as the Athlon64, calling it "Intel 64-bit with Extended Memory Technoloty". Basically they couldn't say they copied AMD without being laughed at in irony (since AMD got its start by simply copying Intel's chips).

And I'm sure that's much more information than you care to know.. but now you do. Amaze your friends.

rch1231,

I am pasting another text from the same thread,

Then there's the choice between i386, x86_64, and ppc. Here's how to figure out which one you need:

* i386 - If you have a Pentium or Celeron (meaning any Pentium or Celeron, including a Pentium 4, Pentium M, etc.) or the original Core Duo (not a Core 2 Duo).
* x86_64 - If you have a Core 2 Duo, Core Solo, Opteron, Athlon 64, Turion 64, or Sempron. (This also includes the new "Intel Mac" machines.)
* ppc - Any modern Mac that's not an Intel Mac.

From this post it appears my machine turion 64 is x86_64

Does it mean my machine is capable of running any 64 bit os?

Yes to both questions. The Tution64 is in the same class processors as the Athlon64 and is able to run 64bit OS. Linux wise you can run it using i386, i586, i686, x86_64. Windows you can run either the 32bit or 64bit OS versions however there are applications that do not run properly under windows XP64 or Vista64 or require a different version. Windows 7 has a specific WindowsXP32 compatibility mode to address these issues.
