Shared L2 cache vs. separate Shared cache allows a larger cache to be available to one core if it needs it (and assumes the other core does not need it). This is dynamic allocation of the cache resource. 3. Integrated memory controller vs. non-integrated The presence of the System Request Interface, Cross bar, and the high-speed serial interface (HyperTransport) are all logical results of having an integrated memory controller It is difficult to say which implementation/system architecture is better. They simply are a different means to the end. What matters is how they perform on a given workload. 幻灯片 36 幻灯片 37 幻灯片 38 幻灯片 39 Intel Turbo Boost Technology increases performance of both multi-threaded and single threaded workloads. Intel Turbo Boost Technology is activated when the Operating System (OS) requests the highest processor performance state (P0). The maximum frequency of Intel? Turbo Boost Technology is dependent on the number of active cores. The amount of time the processor spends in the Intel Turbo Boost Technology state depends on the workload and operating environment, providing the performance you need, when and where you need it. Any of the following can set the upper limit of Intel Turbo Boost Technology on a given workload: Number of active cores Estimated current consumption Estimated power consumption Processor temperature When the processor is operating below these limits and the users workload demands additional performance, the processor frequency will dynamically increase by 133 MHz on short and regular intervals until the upper limit is met or the maximum possible upside for
