Model name : Intel(R) Xeon(R) CPU 5160 3.00GHz The higher clock rate (3.0 GHz vs 2.3GHz) should offer slightly better performance than example 3. Each core shares the 4MB cache with its sibling core. There are a total of 4 cores : 2 cores in 2 separate socketed physical CPUs. email protected cat /proc/cpuinfo processor : 0 vendorid : GenuineIntel cpu family : 6 model : 29 model name : Intel(R) Xeon(R) CPU E7450 2.40GHz stepping : 1 cpu MHz : 2400.158 cache size : 12288 KB physical id : 0 siblings : 1 core id : 0 cpu cores : 1 apicid : 0 initial apicid : 0 fpu : yes fpuexception : yes cpuid level : 11 wp : yes flags : fpu de tsc msr pae mce cx8 apic sep mtrr mca cmov pat clflush acpi mmx fxsr sse sse2 ss ht syscall lm constanttsc up repgood aperfmperf. Of the 5 examples this should be the most capable system processor-wise. Model name : Intel(R) Xeon(TM) CPU 3.60GHzĮxample 5. The number of siblings is twice the number of cores, which is another clue that this is a system with hyperthreading enabled. This example shows that processer 0 and 2 share the same physical CPU and 1 and 3 share the same physical CPU. Dual Single core CPU, Hyperthreading ENABLED processor : 0 vendorid : GenuineIntel cpu family : 6 model : 23 model name : Intel(R) Core(TM)2 CPU E8400 3.00GHz stepping : 10 cpu MHz : 2999.820 cache.

Model name : Intel(R) Xeon(R) CPU E5410 2.33GHzĪgain, each processor has its own core so this is a dual core system. That makes sense though, when considering 4 cores share that L2 cache. The number of siblings matches the number of cores so there are no Hyperthreading siblings. Notice how each processor has its own core id. Model name : Intel(R) Pentium(R) 4 CPU 2.80GHz The physical CPU id is the same for both: 0. Notice how we have 2 siblings, but only 1 core. 相同的physical id,相同的core id,但是不同的processor id,表明是同一个core上的逻辑CPU(超线程)Ĭpuinfo示例如下所示(原文引用已经找不到了,直接贴在这里) Example 1: Single processor, 1 core, no Hyperthreading Processor : 0Įxample 2: Single processor, 1 core, Hyperthreading is enabled.Menu 理解Linux下的CPU信息:lscpu & cpuinfo 07 April 2017 on linux, CPU
