For laptops and desktops, you really can't beat the Core architecture (for
which Intel has stupidly named the CPUs Core2). In single-core and
dual-core setups, these are the best CPUs around.
For servers, though, I still prefer Opterons, and that's mainly due to the
NUMA setup, proper support for amd64 extensions, better hardware
virtualisation (although that's still in theory as we haven't used any
CPUs that support it), and better all-around running in our testing. Not
to mention the fact that you can upgrade the CPU without requiring a
wholee new motherboard. When will Intel learn that bumping the CPU speed
should not require a new chipset and motherboard??
