2、tel processor has a smaller 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-integr
3、atedThe 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.
4、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 st
5、ate (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
6、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 perf
7、ormance, 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 the number of active cores is reached. Conversely, when any of the limits are reached or exceeded, the processor frequency will automat
8、ically decrease by 133 MHz until the processor is again operating within its limits.Example for 4C Turbo operation: A database query, which doesnt 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.幻灯片 40幻灯片 4
9、1Key points: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 per
10、formance 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!幻灯片 42幻灯片 43幻灯片 44幻灯片 45幻灯片 46幻灯片 47幻灯片 48幻灯片 49幻
