[freeloader]

freeloader yet you are still missing 10-20% of performance, thats a lot not to mention what they added was just a second cluster which means only 20% bigger core size without L2 cache, true 2 core without sharing would mean 100% bigger core size on a die.
something like this(without L2 cache)
module without one integer(no sharing, everything can be used by one integer cluster) 15.58mm2
module design 19.4mm2
2 core design 2*15.58mm2=31.16mm2
The performance gain per area increase is worth the performance penalty but comparing it to a regular 8 core is not right in my opinion thanks to the penalty hit.

Too me it's no different than Intel classifying it's parts as having 4 cores/8 threads. Bulldozer's turbo function will also make up for some of the 10 to 20% deficiencies in a multi threaded work load, however no processor (that I'm aware of) with a shared cache system can obtain a 100% unified work load over two cores on the same die. (cache latency, cache miss, operating system overhead, etc, etc...)
