Yonah 1 s Intel Dual Core Yonah Details

Intel has demonstrated design concept desktop PC based on the Intel
Dual Core Pentium M “Yonah” processor. The desktop PC is really cool looking and
extremely slim and possess all the necessary features. According to
HKEPC
, Intel Dual Core Yonah is 65nm based, PGA 478 or BGA 479 socket, 151M
transistors, 667MHz FSB, Execute Disable Bit and has 2MB shared cache which
Intel calls it “Smart Cache” that delivers better performance, responsiveness
and power savings.

This “Smart Cache” technology enables one active core to have
access to full 2MB cache size instead of just 1 MB while the other core is
sleeping; minimizes bus traffic by allowing both cores to access single copy of
data; L2 and DCU data pre-fetchers and deeper write output buffer for improved
cache performance; Shared bus router enables cache resource optimization in
single and dual-core mode, bandwidth adaptation buffer enables 2x average L2
bandwidth when both cores are active.

Apparently, the first Yonah sample in a Napa notebook based on 945GM Express chipset is clocked at 1.46GHz. Of course, when Yonah is launched in H1 2006, the initial clock speeds and model numbers are expected to be x20 (1.67GHz), x30 (1.83GHz), x40 (2.0GHz) as well as x50 (2.17GHz). There are low voltage versions of Yonah as well; x48 (1.67GHz) and x38 (1.50GHz). Since Intel plans to cancel 955XM chipset, therefore 945PM and 945GM will now support up to 4GB of DDR2 memories.
