Yes.
Warground:
but you can compare it because 2 Bulldozer cores are also not 2 real cores.
--- Quote ---(Wikipedia) "The "module", described as two cores, can be contrasted with a single Intel core with HyperThreading. The only difference between the two approaches is that Bulldozer provides dedicated schedulers and integer units for each thread, whereas in Intel's core all threads must compete for available execution resources.

Amd is calling that CMT (Clustered Multi-Thread)

So the hierarchy would be "2 cores > 1 CMT core > 1 SMT core".
Warground:
yes.
and here some Benchmarks:
AMD Opteron 3280 (Kaphost): 5722 Points
http://www.cpubenchmark.net/cpu.php?cpu=AMD+Opteron+3280
Intel Core i7-3770 @ 3.40GHz(ATFclan.eu): 10359 Points
http://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i7-3770+%40+3.40GHz
as you can see I7 of Hetzner (ATF) is almost twice as fast as the opteron of Server4you (Kaphost).
Kalphiter:
CPU is always not full, and single-core performance for each BL instance will be fine.
I've never seen full CPU usage on a server except for crashed servers (Gravity Cat's usually does this) and Glass' server.
As long as single-core performance is OK, then it's all about total power. For some reason 32-bit Windows programs can only use up the power of one core, however this can be spread across multiple cores. I have no idea how it works. It's a non-issue. Not sure if Lub boasted about single-core performance, but if he did, he has no loving clue what he's talking about.
