Engineering models clarkdale already exist and were successfully overclocked to 4.0 GHz with the relatively modest voltage on the core. Many are undoubtedly interested not only in the overclocking potential, but also in performance increase, ensured by clarkdale processors in comparison with predecessors.
As the rival to the engineering model clarkdale with 3.06 GHz frequency was selected the Core 2 Duo e8400 (3.0 GHz). Both processors were coupled with 2 X 2 Gb memory DDR3-1333. The Graphic system was based on video card radeon HD 4870 with 1 Gb memory. Synthetic tests revealed an obvious advantage Of clarkdale in the memory system speed plan , whereas in real applications it was impossible to attain always a significant advantage . The support Of hyper-Threading gives Clarkdale two virtual core, which justify their presence in rendering and video task . But for gaming, we see about the same performance.
Associate was not able to overclock the processor clarkdale more than 4 GHz even with the increased voltage. Possibly, in the overclock of LGA 1156 processors there are some nuances.
