Bulldozer will be x86 processing, which in turn makes me ask the question..

Why?

Did they find good reason to go back to x86?

If so, are there benefits in sticking with x86 processing?

lol...

All chips are x86 bro.

They just added an extension, x86-64.

It's been that way for years.

Umm... what? All of AMD's recent and future chips are 64-bit. :S

x86-64

As opposed to x86, or IA64, or whatever.

Since about 2004 AMD Athlon has touted the x64 thang, and the opty a year before.

This had me worried when I saw info on Wiki...

Thanks for this good info guys.. +Rep to all of you who helped..

The only dumb question is the ones you don't ask...

idk i read on wikipedia that apparently that its actually not using 64bit for some reason, instead it is using 54bit as the size of the cache on cpus are not large enough to be equivalent to handle 64bit registers as effectively because of the space they use. In other words less cache thrashing which causes performance hits when the cpu is doing its thing.

It's better to ask a question and look like a fool for a moment than to not ask the question and continue being ignorant of the answer.

Another example of wikifail, I don't trust anything I read there unless there is a citation from a reputable source. It can be good to do a little quick learning about something but that's about it.

Bulldozer is actually rumored to have 128bit OS's supported later on in its releases. I read that windows 8 will have a partially functioning 128bit version. windows 9 will be fully 128bit ready. I saw that windows 8 will also only be 64bit. So any CPU that isn't 64bit won't be supported.

TY, much needed in these forums were Fail seems to be the most overly used word in some people's vocabulary...

Good point.. +Rep

IA128 is different from X86-64 or X86-128.
IA64 was not compatible with X86 applications.
Source seems kind of bugged.

i wasn't say that it was hard set in stone correct, just showing what I read. I took it with a grain of salt.

What's the benefit of a 128-bit OS? Quad-precision Floating Point is rare even in HPCs and non-existent in desktop use.

You can't be partially functioning 128-bit. You either are or are not.

Its great for somethings but you have to double check
