There's not much surprise that Barcelona lags Core2 in integer IPC, which is compounded by the low clock speeds.
The FP on a per-core basis also lags somewhat.
The platform's scalability keeps Barcelona competitive in the 2S space, and Intel's FSB bottleneck is more telling at 4S, at least for bandwidth-hungry FP apps.
AMD's hold on integer apps is waning, though, for both single-socket and multisocket. Thanks to the L3, the latency at these low clocks is closer to a Xeon than it is to K8, and the cache per core is very lean.
Phenom's desktop fortunes from these numbers don't look too hot.
As has been pointed out before when there weren't hard numbers to back it up, almost none of Barcelona's scalability advantages over Core2 apply in single-socket.
FB-DIMMs also don't hinder Conroe on the desktop either.
I guess we'll see what happens when AMD's memory controller is clocked higher in later speed grades, since the higher speed should reduce (but never eliminate) the latency penalty of the L3.
It does look like AMD's competitive niche is getting smaller.
I bet Shanghai would have been nice to have out right about now.
