Well a clear point - it's application dependent. I'm sure high communication computing could be sped up since core 0 and core 0-h would communicate through the same cache, without using slow RAM.

@Mikhail, then the problem is that if both threads require a large amount of processing power then they will both be competing for the same resources and would be much better off communicating through either the CPUs shared L3 cache (the i7 has L1 & L2 cache per core and a shared L3 cache) or even system memory and doing their tasks separately. It's all a massive swings-and-roundabouts exercise...
