Yonah - 64bit vs. 32bit

I've been reading that the Yonah processors that are now shipping supposedly support 64 bit (well, I remember reading a long time ago that all Yonah's supported 64bit, but that it was disabled. Now it's shipping with that feature enabled).

If that's the case, does anyone know how to tell the difference if you wanted to get a laptop with one?

Yonah do not support 64bit because it is based on a modified Dothan core.And it is not shipping with that feature enabled.
 
I really like Intel and All. But yonah 64bit shipping now with it, is news to me . got a link

Hexus report on Yonah supporting 64-bit: http://www.hexus.net/content/item.php?item=4604


"It seems that the Intel Core Duo processors that are all the rage these days may be a little more powerful than Intel would have you know. Thanks to a little detective work, it’s been discovered that the processors, deep down inside, are actually 64-bit compatible. Yes, that Core Duo you have right now is a 64-bit chip. Intel openly admits that its Sossaman chips are 64-bit, but does not mention this fact about its consumer-targetted Yonah chips, despite the fact that the two are one in the same. What consumer (or geek) would not want to play around with a 64-bit Linux distribution, or Windows 64-bit for that matter? Intel may just have some explaining to do."

Honestly, I'm not completely certain either. Some reports say Sossaman is only 32 bit, other reports say that Intel says Sossaman is 64 bit, and that it's simply a derivative of Yonah.

The fact that the chip is based on Yonah also restricts the new Xeon to 32-bit application environments, while the preceding single-core Xeon LV included a 64-bit instruction set (EM64T).

See page 4 of the Xeon LV platform brief: ftp://download.intel.com/products/processor/xeon/xeon_lv_platbrief.pdf and the Xeon product comparison page: http://indigo.intel.com/compare_cpu/showchart.aspx?mmID=876095,872118&familyID=5&culture=en-US

Sossaman is a 32-bit chip. Hexus is wrong. Intel pretty much settles it above.

Thanks for the links.

That saddens me though. It would have been nice... :/

Oh well, my Merom count-down continues.
