core2duo VS core2quad

The advantages of dual-core Core 2 Duo E6850 over the quad-core Core 2 Quad Q6600:

* 25% higher clock speed ensuring higher performance in applications that aren’t optimized for multi-threading;
* Higher bus frequency that increases the memory subsystem performance. Peak bandwidth of the bus between the processor and memory for CPUs with 1333MHz bus is 10.7GB/s vs. 8.5GB/s by CPUs with 1067MHz bus.
* 46% lower heat dissipation that allows using relatively simple and inexpensive cooling solutions, even during overclocking.

The advantages of the quad-core Core 2 Quad Q6600 over dual-core Core 2 Duo E6850:

* Twice as many computational cores that ensure higher performance in multi-threaded applications.
* Twice as large L2 cache memory. It is especially crucial for Windows Vista users as this operating system can distribute computational threads intellectually over the cores with shared or exclusive L2 cache.
