However, when that does become a reality it won’t be something to worry about until a new generation of hybrid-aware software becomes mainstream, and even then it will be a choice mainly aimed at laptop users. We haven’t yet seen a situation where two CPUs have the same number of P-cores, but different numbers of E-cores. Any additional overhead offered by the E-cores is a bonus. You need enough performance cores to run your most demanding application. The best advice we can give is to pay attention to the number of P-cores first and foremost. When you next buy a new CPU, there’s a good chance you’ll have to make a decision on how many P- and E-cores you want. While Windows 10 will work, it’s not doing so as well as it should and patches to bring it up to speed are still in the works. At the time of writing in January 2022, Windows 11 has a new CPU task scheduler that’s aware of how to assign work to the different types of cores. If you’re a Windows 10 user looking to upgrade to one of these hybrid CPUs, you may want to either wait or go ahead and upgrade to Windows 11. By the time you read this, the worst incompatibility issues may be resolved. So yes, one NUMA node equals one socket, at least in typical multi-socket Xeon systems.Software patches as well as motherboard level legacy-mode workarounds are sure to come thick and fast. In your system, logical cores 0–13 and 28–41 are in one NUMA node, the rest in the other. It will regard 'anything' that can take care of one process at a time as a processor. As a result, not all physical memory is equally accessible from all CPUs: one physical CPU can directly access the memory it controls, but has to go through the other physical CPU to access the rest of memory. The cpuinfo report abstracts out the fact that each physical processor (one of several cpu's on a die) can expand its computing powers by tech feats such as multithreading. In your system, each socket is attached to certain DIMM slots, and each physical CPU package contains a memory controller which handles part of the total RAM. “NUMA node” represents the memory architecture “NUMA” stands for “non-uniform memory architecture”. Notices Welcome to, a friendly and active Linux Community. If it is Linux Related and doesn't seem to fit in any other forum then this is the place. In your case, you have two sockets, each containing a 14-core Xeon E5-2690 v4 CPU, and since that supports hyper-threading with two threads, each core can run two threads. CPU architecture explanation with /proc/cpuinfo CPU architecture explanation with /proc/cpuinfo Linux - General This Linux forum is for general Linux questions and discussion. One socket is one physical CPU package (which occupies one socket on the motherboard) each socket hosts a number of physical cores, and each core can run one or more threads. “CPU(s): 56” represents the number of logical cores, which equals “Thread(s) per core” × “Core(s) per socket” × “Socket(s)”. Question 2: What does this NUMA node mean? Does it represent the socket? Question 1: What does this CPUs(s): 56 denote? Does CPU(s) denote number of Virtual/Logical core, as it cannot be a Physical core core atleast? I can see that Thread(s) per core: 2, so these 28 cores can behave like 2x28=56 logical cores. cpu family Authoritatively tells you the type of processor you have in the system. If you have more than one processor it will display all processor information separately counting the processors using zero notation. But, as shown in the output CPUs(s): 56 and this is what is confusing me. If you have one processor it will display a 0. Normally, a CPU can contain multiple cores, so number of CPUs can never be smaller than number of Cores. I can see that there are 2 sockets (which is like a processor ?) and inside each of the socket we have 14 cores. Model name: Intel(R) Xeon(R) CPU E5-2690 v4 2.60GHz You can see the output from lscpu command - lscpu
