According to some datasheets we have seen, the 90nm Athlon 64 CPUs
“Winchester” for desktop and “Oakville” for mobile have a VCore of 1.35V
compared to 1.5V on the current 130nm Athlon 64. The new stepping of the 90nm
Athlon 64 is DH8-D0 compared to the current DH7-CG stepping. The CPUID is
changed to 10FC0 and has a longer OPN code ending with KX4LB for the mobile
“Oakville”. Interestingly, the new “D0″ Athlon 64 will offer better performance
compared to the current “CG” Athlon 64 from first tests done by our friend
Boss50 using “D0″ Athlon 64 3500+ (2.2Ghz) on nForce3 250 board.

Franck, the author of CPU-Z has updated a newer revision of CPU-Z 1.23 for
VR-Zone but unfortunately, the ES Winchester won’t be detected as a Winchester
and stepping is not detected accurately yet
as more supporting docs are needed from AMD. CPU-Z for VR-Zone edition can
support Sempron and this feature is still not in current CPU-Z 1.23 out there so
drop by our OCDB page
and download it.

according to CPUID’s eax output.

Interestingly, the new “D0″ Athlon 64 will offer better performance compared
to the current “CG” Athlon 64 from first tests done by our friend Boss50 using
“D0″ Athlon 64 3500+ (2.2Ghz) on nForce3 250 board. The CPUMark for “D0″ 3500+
is 256 compared to 242 of the “CG” 3500+ and SuperPI 1M calculation is 1s
faster. The performance improvement could be due to the increase in speed of the
embedded memory controller as AMD has
revealed previously.
We will see a performance war between 90nm Athlon 64 and 1066Mhz FSB Prescott
later this year.
