Provides two dual copies of data for dual processors B. provides fault tolerance C. Allows data to be kept in memory even when the pc loses power D. allows a processor to access data more quickly - -D. allows a processor to access data more quickly You have an AMD processor and an intel processor, both have same speed rating and same front-side bus rate. Which of the following statements is true about the relative performance of both processors? A. AMD processor has better peformance than the intel B. both processors will perform same C. performance depends on other factors /cache/etc. D. intel processor has better perf than amd - -C. performance depends on other factors /cache/etc. Which of the following processor features is used to dynamically reduce power consumption based on current operating conditions? A. throttling B. overclocking C. hyper-threading D. caching E. multi-core - -A. throttling What is true of processor cache? (select two) A. all other thing = processor with L2 cache performs better than l3 cache B. L1 is typically unique to a processor core C. L3 is shared b/w all cores D. L1 is the largest type of cache E. L3 cache is typically on the mb - -B. L1 is typically unique to a processor core C. L3 is shared b/w all cores FUrther: L1 cache is integrated on processor die itself and unique to processor core on multi-core systems.
