Logical processor Vs Cores Vs Threads. Article 06/30/2015 QuestionTuesday, June 30, 2015 2:43 PMI am trying to understand CPU architecture deeply like cores, logical processors and vcpus. For Cores I understood that in main physical unit the separate operation uni...
让我们回到奔腾(Pentium)处理器的年代,那时候诸如 多核(multi-core)、虚拟CPU(virtual CPU)、逻辑CPU(virtual CPU)的概念还不存在,绝大多数的计算机在它们的主板上仅仅安装 单独的一块大容量芯片,我们称之为 微处理器、处理器或者 简单的CPU(microprocessor, processor or simply CPU)。只有少数的一些企业级计算机...
At the operating system level, a physical quad-core processor would be shown as a 4 cpu computer. But these would be 4 logical CPUs or non-physical LCPUs. If the processor additionaly offers HyperThreading technology, commands such ashtopornprocwould indicate that there are 8 cpus in the...
Difference between core and processor? A core is usually the basic computation unit of the CPU - it can run a single program context (or multiple ones if it supports hardware threads such as hyperthreading on Intel CPUs), maintaining the correct program state, registers, and correct execution ...
processor cores:处理器核心数,即俗称的“CPU核心数”。例如“Intel Core i3-2310M”是双核处理器,它有2个“处理器核心数”。 logical processors:逻辑处理器数,即俗称的“逻辑CPU数”。例如“Intel Core i3-2310M”支持超线程,一个物理核心能模拟为两个逻辑处理器,即一块“Intel Core i3-2310M”有4个“逻辑...
Of course it would still be better to have 2 dual-core processors than one, but even better would be to have a single quad-core. At the operating system level, a physical quad-core processor would be shown as a 4 cpu computer. But these would be 4 logical CPUs or non-physical L...

DUMMYUNIONNAME.ProcessorCore 仅当Relationship成员为 RelationProcessorCore 时,此结构才包含有效数据。 DUMMYUNIONNAME.ProcessorCore.Flags 如果此成员的值为 1,则由ProcessorMask成员的值标识的逻辑处理器共享功能单元,如在超线程或 SMT 中一样。 否则,标识的逻辑处理器不会共享功能单元。
The Performance tab shows the overall processor usage or processor usage of eachlogical processor. A logical processor could be a socket, a core, or a simultaneous multithreading (SMT) processor such as Hyper-Threading (HT) or Clustered MultiThreading (CMT) processor. This means that a two-socke...
