Intel Core i3 CPU is not 64 bit?

According to this page:

https://help.ubuntu.com/community/32bit_and_64bit

the following Intel CPU's are 64bit:

Intel
F and 5x1 series Pentium 4 using the "Prescott" core
Pentium D
Core 2 (Solo, Duo & Quad)
Core i5 (all)
Core i7 (all)

Isn't the Core i3 64 bit too?

Solution 1:

My laptop is an Core i3. I have a dual boot - one with 64bit Ubuntu (12.04) and one with a 32bit Ubuntu (11.10).

So, yes - it is a 64bit capable machine.

I'll update the wiki

Solution 2:

They must have left it out. It is 64 bit, there is the Intel 64 support which is an x86-64 extension like AMD64. http://en.wikipedia.org/wiki/List_of_Intel_Core_i3_microprocessors

And here: http://en.wikipedia.org/wiki/Intel_64#Intel_64

Solution 3:

All i3 supports Intel 64, which is Intel's implementation of x86-64, so yes, i3 is 64bit.
