The lscpu command output provides detailed information about your system’s CPU architecture and configuration. Here’s a breakdown of the key details from your output:

Architecture: x86_64
Your CPU is a 64-bit processor, capable of running both 32-bit and 64-bit applications.
CPU op-mode(s): 32-bit, 64-bit
The CPU supports both 32-bit and 64-bit operating modes.
Address sizes: 39 bits physical, 48 bits virtual
The CPU can address up to 2^39 bytes (512 GB) of physical memory and 2^48 bytes (256 TB) of virtual memory.
Byte Order: Little Endian
Data is stored with the least significant byte first, standard for x86 architectures.
CPU(s): 32
The system has 32 logical CPUs (combination of physical cores and threads).
On-line CPU(s) list: 0-31
All 32 logical CPUs are active and available.
Vendor ID: GenuineIntel
The CPU is manufactured by Intel.
Model name: 13th Gen Intel(R) Core(TM) i9-13900KF
You have a 13th-generation Intel Core i9-13900KF processor, a high-performance CPU designed for desktops, lacking an integrated GPU (denoted by the “F” suffix).
CPU family: 6
Intel’s CPU family identifier (common for Intel processors).
Model: 183
Specific model number for this CPU.
Thread(s) per core: 2
Each physical core supports two threads (hyper-threading enabled).
Core(s) per socket: 24
The CPU has 24 physical cores per socket. This includes 8 performance cores (P-cores) and 16 efficiency cores (E-cores), typical for the i9-13900KF.
Socket(s): 1
There is one physical CPU socket on the motherboard.
Stepping: 1
Indicates the revision of the CPU silicon.
CPU max MHz: 5800.0000
The maximum clock speed (turbo boost) is 5.8 GHz.
CPU min MHz: 800.0000
The minimum clock speed is 800 MHz (protectorate mode: intel_pstate=passive
BogoMIPS: 5990.40
A rough estimate of CPU performance (not highly relevant today).
Flags:
Lists CPU features and instruction sets supported, such as avx, avx2, fma, aes, and hyper-threading (ht). These enable specific optimizations and security features.
Virtualization: VT-x
Supports Intel’s hardware-assisted virtualization technology.
Caches:
- L1d: 896 KiB (data cache, 24 instances, ~36 KiB per core)
- L1i: 1.3 MiB (instruction cache, ~56 KiB per core)
- L2: 32 MiB (shared among cores, typically 2 MB per P-core, 4 MB per E-core cluster)
- L3: 36 MiB (shared cache across all cores)
NUMA: 1 node, 0-31 CPUs
Non-Uniform Memory Access configuration; all CPUs are in one NUMA node, typical for single-socket systems.
Vulnerabilities:
Lists known CPU vulnerabilities and their mitigation status. Most are “Not affected” or mitigated (e.g., Spectre, Meltdown) via hardware or software fixes.

Summary

You have a powerful 13th Gen Intel Core i9-13900KF processor with 24 cores (8 P-cores + 16 E-cores), 32 threads, and a max turbo speed of 5.8 GHz. It’s designed for high-performance tasks like gaming, content creation, and multitasking, with no integrated GPU. The system is well-protected against known CPU vulnerabilities and supports advanced features like hyper-threading and virtualization.
