![]() However, I dont understand why the processor speed in the model name line differs from the cpu MHz number. cat /proc/cpuinfo correctly shows me 12 processors. Vendor ID: "GenuineIntel" CPUID level 10Įxtended brand string: "Genuine Intel(R) CPU T2400 1. On a system running Gentoo Linux (3.1.6, x8664), I have two six-core Intel Xeon CPUs (X5675). cat /proc/cpuinfo grep Hz model name : Intel(R) Xeon(R) CPU E5-2643 0 3.30GHz cpu MHz : 3300.179 If the CPU frquency displayed by the cpu MHz and model. The governor "ondemand" may decide which speed to useĬurrent CPU frequency is 1000 MHz (asserted by call to hardware). ![]() Model name : Genuine Intel(R) CPU T2400 1.83GHzįlags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx constant_tsc pni monitor vmx est tm2 xtpr On a multi-core system such as an i7 or i5 you can see this with this command: cat. piraspberrypi4: cat /proc/cpuinfo processor : 0 model name : ARMv7 Processor rev 3 (v7l) BogoMIPS : 108. cat /proc/cpuinfo Specifically this line: model name : Intel(R) Core(TM) i5 CPU M 560 2.67GHz The line that shows cpu MHz doesnt show the maximum speed of your CPU. Ive heard the RPi manufacturers cant change this without a lot of hassle, though.

We already knew how to check if a Linux OS is 32 bit or 64 bit and how to find if a Linux system is physical or virtual machine.Today, we are going to learn yet another useful topic i.e. You can easily read its content and display it. The final item, bogomips, is a Linux-specific measurement of the CPU's speed in MIPS (millions of instructions per second) while not performing any actual work it is not an accurate indicator of overall processor speed and is only used for some testing purposes.Ĭopyright © 2006 The Linux Information Project. The /proc/cpuinfo is a read-only file that contains information about the central processing units on a machine. The flags field shows which features are available in the CPU this information is of interest only to users with an in-depth knowledge of processors. cat /proc/cpuinfo processor : 0 vendorid : GenuineIntel cpu family : 6 model : 8 model name : Celeron (Coppermine) stepping : 10 cpu MHz : 1002.232 cache. Among them are processor (the value of which is zero for single-processor systems), vendor_id (the value of which is GenuineIntel in the case of an Intel processor), cpu family, model_name, cpu MHz (processor speed in millions of cycles per second), cache size (the amount of high speed cache memory built into the processor) and fpu (the value of which is yes if the processor contains a floating point unit). Only a few of the lines contain information that is meaningful to most users. But you can filter the results to get the relevantinfo. Each key word can be any combination of alphanumeric, underscore and space characters. cat /proc/cpuinfo It gets you info related to individual cores making it too long to read. The information about each processor consists of a set of lines (18 on Red Hat 9), each of which contains a key word followed by a separator (consisting of spaces, a colon and then another space) and then by a value. If a computer contains two or more CPUs, the information about each is separated by a blank line. Code: Select all piraspberrypi: cat /proc/cpuinfo processor : 0 model name : ARMv7 Processor rev 4 (v7l) BogoMIPS : 38. It can easily be read with a command such as cat, i.e., proc/cpuinfo is a short, read-only, plain text file that contains information about the CPUs (central processing units) on a computer.
