The reason is pretty simple. Up until recently Intel did not really sell much in terms of 64 bit.
Core2duo etc were all 32bit.
Also Intel pretty much own the giants share of the market. So get to dictate a pretty large chuck.
This is why many Linux users also used AMD's.

But the whole thing has changed over the last 5 years or so. A classic example of this is a little company called FOXCONN who made reliable desktop chassis have pretty much grown 10 fold and dropped desktops all together......

But until we get rid of all the P4, Core2, QuadCore......CPU's - expect x86 software for a long time to come.

Now on to ivp6 and why it didn't happen way back in 1997......

umm the core2duo is 64bit

From what I've read 64 bit is x64 and 32 bit is x86.

I read three wrong posts in that thread and stopped.

Do you know what an 'x86' is?

What was your first computer? Do you need a history lesson?

A family of instruction set architectures based on the Intel 8086 CPU.

My first computer was (don't laugh) a Pentium 200.

A history lesson sounds good.

So the instructions set in the 64 bit CPU, backwards compatible with a 32 bit or 16 bit system?

Mine was a Sinclair ZX81 - which I still have.

I know that a 64 bit OS can't be installed on a 32 bit CPU system. However, I think that some 64 bit apps can work on 32 bit hardware with reduced functionality. I don't know much about this kind of stuff.

Some of it is to do with word length sonny jim. http://en.wikipedia.org/wiki/Word_(computing)

Back in the day, when these pesky modern fangled 16 bit processors arrived, lazy programmers like me had to modify half their code, as during bit shifting operations you assumed things like integers being 8 bits. Over time, programmers should have got less lazy and used the stricter standard types. Unfortunately lots of apps are still written in a similar fashion, just that now they assume integers being 32 bits.

Not all versions.......infact only 45nm versions were 86-64 (which in some eyes is not considered not true 64bit as it was manipulated 32 (long-to-int etc)

You will prob find only a small % of the core2duo sold in NZ could act 64bit

The year intel made their first buck in processors heh

As long as they can "see" more than 3GB of RAM it's all good.

From what I've read 64 bit is x64 and 32 bit is x86.

The x86 refers to 8086, the processor and instruction set. Went all the way through to the 80286 and was later replaced by x86-32 for the 80386, 80486 and so forth. They currently refer to x86-32 (Intel CE, some Atom processors) and x86-64 (Other Atom, Pentium, Core I3,I5,I7, etc.)

You're either running a 64bit or a 32bit operating system on a x86-(bit) processor.

I currently run Windows 2008 R2, mainly for SQL Server and Hyper-V. I don't have any problems with the games I run. I do run a Windows 7 VM though for when I need to dev work against it.

And first computer? Was a Commodore VIC 20. Unless you count that funny little Sharp calculator that came in a briefcase with a 4 pen colour printer
