What is an advantage of a P0WER8 system compared to an x86 solution?

The correct answer is B. More cores per socket. Systems that are designed with fewer components and interconnects have fewer opportunities to fail. Simple design choices, such as integrating processor cores on a single POWER chip, can reduce the opportunity for system failures. The POWER8 chip has more cores per processor…

Explanation

Systems that are designed with fewer components and interconnects have fewer opportunities to fail. Simple design choices, such as integrating processor cores on a single POWER chip, can reduce the opportunity for system failures. The POWER8 chip has more cores per processor module, and the I/O Hub Controller function is integrated in the processor module, which generates a PCIe BUS directly from the processor module. Parts selection also plays a critical role in overall system reliability.
