问:K5和Intel的奔腾有何不同,为什么用P-Rating来标定K5的性能? 答:K5和Intel奔腾的外部特性完全一样,但内部结构和设计技术方面K5比奔腾高大约一代,和P6的技术基本在同一水平,只是没有将第二级高速缓存封装在芯片中而已。K5和奔腾的最大不同从现在的情况看就是电压的差异,奔腾的工作电压基本采用3.3V,K5目前的工作电压采用3.45～3.6V(标准工作电压为3.52V)。P-Rating是AMD等公司为了标定CPU的性能。以Winstone为基础,对他们的CPU产品进行评测。如果运行结果达到了奔腾75的水平,该CPU就以PR75标定。
Q: K5 and Intel’s Pentium is different, why the use of P-Rating to calibrate the performance of K5? A: K5 and Intel Pentium’s external characteristics exactly the same, but the internal structure and design technology K5 Pentium about high generation, and P6 The technology is basically the same level, but not the second level cache package in the chip only. K5 and Pentium biggest difference from the current situation is the voltage difference, Pentium’s operating voltage is basically 3.3V, K5 current operating voltage 3.45 ~ 3.6V (standard operating voltage of 3.52V). P-Rating is AMD and other companies in order to calibrate the CPU performance. Based on Winstone, evaluate their CPU products. If the result of the operation reaches the level of Pentium 75, the CPU is calibrated with PR75.
