This is dynamic allocation of the cache resource.3. Integrated memory controller vs. non-integratedThe presence of the System Request Interface, Cross bar, and the high-speed serial interface (HyperTransport) are all logical results of having an integrated memory controllerIt 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 39Intel 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 consumpt...
