You can easily notice that the differences between the dual core concepts from Intel and AMD are not very significant: this way or another, we have two processing cores, each one is equipped with its own L1 and L2 Caches.
However, this arbiter (aka Crossbar Switch in AMD terms ) can sort of organize interaction between the cores as well (to all appearances, it means that one core can fetch necessary data from L2 Cache of the other core, saving on long queries to main RAM and lowering the memory controller load, as well as ensuring cache coherence). Thus, there appears a counterpart of the bus arbiter (Hello, Intel!) that organizes interactions between the cores and the shared buses. But if the Pentium XE / Pentium D package theoretically must turn out a tad larger than the doubled original dimensions (due to the integrated arbiter for the dual core bus), in case of Athlon 64 X2 it must be a tad smaller than the total of two processors, because memory and Hyper Transport bus controllers are not replicated in the dual core processor from AMD, both cores share them. Like the dual core processor from Intel, Athlon 64 X2 actually comprises two almost equal processors, integrated into a single die.
The second CPU from this new series: AMD Athlon 64 X2 4800+.
