Cpu sockets in linux

What is cores per socket in Linux?

We can get the number of physical and logical CPU cores using lscpu command in Linux as follows. Each CPU socket has 8 physical cores. Hence, the computer has 16 physical cores in total. Core(s) per socket: 8. Each physical CPU core can run 2 threads.

How many CPUs can be in a socket?

A normal PC only have one socket. Cores are the number of CPU-cores per CPU capsule. A modern standard CPU for a standard PC usually have two or four cores. And some CPUs can run more than one parallel thread per CPU-core.

How many CPU cores do I have Linux?

You can use one of the following command to find the number of physical CPU cores including all cores on Linux:

1. lscpu command.
2. cat /proc/cpuinfo.
3. top or htop command.
4. nproc command.
5. hwinfo command.
6. dmidecode -t processor command.
7. getconf _NPROCESSORS_ONLN command.

How do I know how many cores a socket has?

To check the distribution of cores across a socket, use the coreinfo -c -s command. To download and install Coreinfo, click here. CPU-Z is a freeware application for Microsoft Windows operating systems which provides information about CPU, processor, cache, memory, system board, graphics, and other hardware features.

What is the difference between sockets and cores?

To get a quick understanding remember that a socket is actually what the CPU chip is connected into via pins and leads and in common language it refers to the chip itself. A core is a full blown CPU sitting on the chip. Basically single socket (chip) may have 1 (one), 2 (two) or 4 (four) cores on it.

How many cores does a VM need?

To use all CPU resources allocated to a virtual machine, it must see one 8 core processor, 2 vCPUs with 4 cores each or 1 vCPU with 4 cores in two threads instead of 8 vCPUs.

How many cores do I need for gaming?

Generally speaking, six cores is usually considered optimal for gaming in 2021. Four cores can still cut it but would hardly be a future-proof solution. Eight or more cores might provide performance improvement, but all this depends mainly on how a particular game is coded and what GPU the CPU would be paired with it.

How do I find memory in Linux?

1. Open the command line.
2. Type the following command: grep MemTotal /proc/meminfo.
3. You should see something similar to the following as output: MemTotal: 4194304 kB.
4. This is your total available memory.

CPU Sockets and Slots

Until recently, each generation of CPU (80386, 80486, and so on) has used a unique CPU/motherboard interface method. These have generally come in the form of sockets, in which the CPU has a number of pins on its bottom that fit into a square connector on the O

motherboard (see Figure 2.2). More recent CPUs, including most Pentium-II, Pentium-III, and H

Athlon CPUs, use a slotted design more like that of plug-in cards. (Most Celeron CPUs con- B

tinue to use a socketed design, but some varieties are available in a slotted form.) A

A socket on motherboards for socketed CPUs contains many holes into which the pins on the bottom of the CPU fit.

Socketed Designs

Most CPU series have seen the coming and going of several socket variants. For instance, the very earliest Pentium CPUs used a pin layout that’s incompatible with what later Pentium

CPUs used. Early 80486 motherboards used sockets that required great force to insert the CPU, but later 80486 motherboards used zero insertion force (ZIF) sockets, in which a lever on one side of the socket allows you to tighten it around an inserted CPU. (This lever is visible to the right of the socket in Figure 2.2.) The vast majority of Pentium-class motherboards use ZIF sockets. Popular sockets for 80486 and later CPUs include

• Socket 1 169-pin socket for 80486 CPUs.

• Socket 2 238-pin socket for 80486 and Pentium Overdrive CPUs.

• Socket 3 237-pin socket for 80486 and Pentium Overdrive CPUs. Includes support for 3.3v operation, which reduces heat generation by CPUs that also support this feature.

• Socket 4 273-pin socket for 60 and 66MHz Pentiums.

• Socket 5 320-pin socket for 75-133MHz Pentiums.

• Socket 7 321-pin socket for Pentiums of 75MHz and above, including Pentium clones from AMD, Cyrix, and IDT. Some motherboards use a Super7 socket design, which is a Socket 7 layout with support for faster bus speeds, as described shortly.

• Socket 8 387-pin socket for Pentium Pro CPUs.

• Socket 370 370-pin socket used by Celeron CPUs.

• Nx586 The NexGen Nx586 CPU used its own unique pinout. Most Nx586 CPUs were not socketed, however; instead, they were soldered directly to their motherboards.

A Socket 6 design was developed, but never implemented on production motherboards.

It’s critically important that you match the socket type to your CPU. You cannot use a CPU that requires one type of socket on a motherboard that uses another. Most 80486 CPUs can be used with Sockets 1 through 3, although some of the more advanced 80486 CPUs require the later Socket 2 or even Socket 3. All Pentium-class motherboards on the market in 2000 are Socket 7 designs (in fact, most implement Super7 features, as well). The motherboard shown in Figure 2.1 is a Socket 7 motherboard. One exception to the interface-matching rule is that Socket 370/Slot 1 adapter cards are available. These allow you to plug a Celeron CPU into a Slot 1 motherboard. Such an adapter might be useful if you want to build a low-cost Celeron computer but plan to upgrade it to a more powerful CPU at some time in the future.

Chapter 2

Socket 7 motherboards are still viable in the marketplace, thanks largely to the AMD K6-2 and K6-III CPUs, which can perform competitively to low-end Intel Pentium-II and Pentium-III CPUs. With AMD’s release of the Athlon CPU, though, AMD is likely to eventually abandon Socket 7 CPUs. Likewise, VIA (which bought Cyrix and IDT late in 1999) has announced that its next CPU wil use a Slot 1 interface. Intel now uses Socket 370 for most of its Celeron CPUs, but the most powerful Intel CPUs use l a slotted CPU interface.

In early 2000, only three types of CPU slots are in common use:

• Slot 1 This 242-pin design is used by Pentium-II, Pentium-III, and some Celeron motherboards.

• Slot 2 This 330-pin design is used by more recent Pentium-II Xeon CPUs. Most Slot 2 motherboards support at least two CPUs.

• Slot A This 242-pin design is used by AMD for its Athlon CPU. (AMD licensed the technology from Digital Equipment Corporation [now Compaq], which uses the design for its Alpha CPU.)

Each slot design is incompatible with the others. Also, although both the AMD Athlon and the Compaq Alpha CPUs use the same CPU bus, they require different motherboards.

How do you determine what type of CPU socket a linux computer has?

What Linux command/program can I use to tell me what type of CPU socket a Linux desktop has? I use CPUZ or SIW on windows, and I can use «cat /proc/cpuinfo» on Linux to get the rest of the possessor’s information, But it does not tell me which socket the CPU is. Thanks.

looking at the board is much faster also check the spec on the machine/board maker most linux will tell you is chipsets, processor archs, and speeds tmk.

If you have x86info installed you can run it with x86info -a and you will get something like this:
