It’s easier to remember as well because it is similar to the ls command. You can see the architecture of your system, number of processors, vendor information, cache information, processor speed etc. This is the simplest command that shows the CPU information in a simple and concise output. I’ll show you my favorite tool for this task along with a few additional ways to check CPUs in Linux. MCE * Supports Machine Check, INT18 and CR4.There are a number of ways you can get information about the processor on your Linux system. TM2 * Implements Thermal Monitor 2 controlĪPIC * Implements software-accessible local APICĬNXT-ID - L1 data cache mode adaptive or BIOS TM * Implements thermal monitor circuitry XTPR * Supports disabling task priority messagesĪCPI * Implements MSR for power management TSC-DEADLINE - Local APIC supports one-shot deadline timer PDCM - Supports Performance Capabilities MSR PCID - Supports PCIDs and settable CR4.PCIDE SEP * Supports fast system call instructionsĭE * Supports I/O breakpoints including CR4.DEĭTES64 - Can write history of 64-bit branch addressesĭS - Implements memory-resident debug bufferĭS-CPL - Supports Debug Store feature with CPL MONITOR - Supports MONITOR and MWAIT instructions OSXSAVE - Supports XSETBV/XGETBV instructionsĬX8 * Supports compare and exchange 8-byte instructionsĭCA - Supports prefetch from memory-mapped deviceį16C - Supports half-precision instructionįXSR * Supports FXSAVE/FXSTOR instructionsįFXSR - Supports optimized FXSAVE/FSRSTOR instruction XSAVE - Supports XSAVE/XRSTOR instructions MTTR * Supports Mmeory Type Range Registers MSR * Implements RDMSR/WRMSR instructions SSE4.2 * Supports Streaming SIMD Extensions 4.2ĪVX - Supports AVX instruction extensionsįMA - Supports FMA extensions using YMM state SSE4.1 * Supports Streaming SIMD Extensions 4.1 SSSE3 * Supports Supplemental SIMD Extensions 3 SSE3 * Supports Streaming SIMD Extensions 3 SSE2 * Supports Streaming SIMD Extensions 2 SS * Supports bus snooping for cache operationsģDNOWEXT - Supports 3DNow! extension instructions PSE36 * Supports > 32-bit address 4-MB pages PAE * Supports > 32-bit physical addresses SVM - Supports AMD hardware-assisted virtualization VMX - Supports Intel hardware-assisted virtualization Intel64 Family 6 Model 26 Stepping 5, GenuineIntel Sysinternals - Intel(R) Xeon(R) CPU W3520 2.67GHz (requires administrative rights on Intel systems).Īll options except -v are selected by default.Ĭoreinfo Output: Coreinfo v3.03 - Dump information on system CPU and memory topology Usage: coreinfo Parameterĭump only virtualization-related features including support for second level address translation. For example, on a 4-core system, a line in theĬache output with a map of shared by cores 3 and 4. That correspond to the specified resources, with '*' representing theĪpplicable processors. Using CoreInfoįor each resource it shows a map of the OS-visible processors InstallationĮxtract the archive to a directory and then run Coreinfo by typing from that directory Coreinfo in the console on a 32 bit Windows version or Coreinfo64 for a 64 bit version. Coreinfo is useful for gaining insight into the processor and cache topology of your system. It uses the Windows’ GetLogicalProcessorInformation function to obtain this information and prints it to the screen, representing a mapping to a logical processor with an asterisk e.g. Coreinfo is a command-line utility that shows you the mapping between logical processors and the physical processor, NUMA node, and socket on which they reside, as well as the cache’s assigned to each logical processor.
