Intel Core 2 Duo or AMD X2 ?

["Joel CARNAT" <joel%carnat.net@localhost>]

Hi,

I plan to replace my AMD Athlon64 (Shuttle SN85G4, nVidia nForce3 250)
with some proc that has hardware virtualization enabled. I will go for a
desktop-like configuration, not a rack server.

Are there any pro/cons for using AMD rather than Intel ?
The target is netbsd/xen as dom0, 3 netbsd/xen as domU and windows/xp domU.
Depending on the RAM I get, there may be another domU for testings and
compilation (netbsd/xen, solaris, ...) that won't be up all time.

I'm thinking of buying one of those :
- Shuttle SD36G5 or AOpen MP945 (Intel 945G/945GM), Intel Core 2 Duo E6420
and 2Go DDR2-SDRAM PC5300
- Shuttle SK22G2 (VIA K8M890CE), AMD dual Core X2 5200 and 4Go of RAM
Any comments, feedback on those ?

My current /xen installation (NetBSD 4.0_BETA2 and xenkernel30-3.0.3) does
not support POWERNOW. Are POWERNOW and/or SPEEDSTEP supported on /xen for
the AMD X2 or Intel Core2Duo ?

TIA,
    Jo
