Intel Core 2 is a microprocessor released by Intel Corporation on July 27, 2006. At the time of its development, this processor has a code name Conroe and Allendale.
Processor performance is pretty much wins hands down when compared with an Intel Pentium D Presler series let alone the Smithfield Pentium D series are still using the Intel NetBurst microarchitecture. When compared with rivals, AMD Athlon FX 60, a processor Intel Core 2 Duo 2400 MHz speed processor outperformed those with differences in the performance of approximately 15%. If the AMD Athlon FX processor is over-clocked to 3.4 GHz, the processor is superior thinner than the Core 2 Duo 2400 MHz. This means the Intel Core 2 Duo is much more efficient than its predecessor in order to execute the instruction.
