2、aller L1 but larger L2 caches.Shared L2 cache vs. separateShared 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-integratedThe presence of th

3、e 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 th

4、ey perform on a given workload.幻燈片 36幻燈片 37幻燈片 38幻燈片 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 f

5、requency 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 fo

6、llowing 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 user's workload demands additional performance, th

7、e 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 the number of active cores is reached. Conversely, when any of the limits are reached or exceeded, the processor frequency will automatically decr

8、ease by 133 MHz until the processor is again operating within its limits.Example for 4C Turbo operation: A database query, which doesn't use any of the processors floating point silicon, so it can take advantage of that thermal headroom and increase the frequency of all 4 cores.幻燈片 40幻燈片 41Key p

9、oints:Highly-differentiated stack: Not just frequency and to a lesser extent FSB, but five major features (describe each)Similar to before, the 2S SKUs are broken down into 3 segments, and weve created two major performance selves to encourage sell-up at strategic points in the stack. Huge performan

10、ce gains between the shelf. Instead of 3-5% bin-to-bin, now youre getting multiple bins of performance. Even with de-featuring the value SKUs, were still over 25% gen-to-gen performance gains from Xeon® 5400.What this also does is create more separation between the bottom and top SKUs, which re

11、ally opens up the top-to-bottom performance gains (over 80% vs NHM as opposed to 30% for HTN). Refer back to the Xeon® 5400 ROI study and project forward to even better TCO as you buy up the stack with Xeon® 5500 series. The buy high,. better ROI story!幻燈片 42幻燈片 43幻燈片 44幻燈片 45幻燈片 46幻燈片 47幻
