inxi -b vs. Dell info.


Using an up-to-date Fedora-34 KDE, the command inxi -b tells me my Dell Inspiron 7591 has an Intel quad-core i5-9300H cpu.

Code:
$ inxi -b
System:    Host: Pluto Kernel: 5.12.15-300.fc34.x86_64 x86_64 bits: 64 Desktop: KDE Plasma 5.22.3 
           Distro: Fedora release 34 (Thirty Four) 
Machine:   Type: Laptop System: Dell product: Inspiron 7591 v: N/A serial: <superuser required> 
           Mobo: Dell model: 0422G6 v: A00 serial: <superuser required> UEFI: Dell v: 1.5.1 date: 11/06/2019 
Battery:   ID-1: BAT0 charge: 41.1 Wh (100.0%) condition: 41.1/56.0 Wh (73.4%) 
CPU:       Info: Quad Core Intel Core i5-9300H [MT MCP] speed: 3932 MHz min/max: 800/4100 MHz 
Graphics:  Device-1: Intel CoffeeLake-H GT2 [UHD Graphics 630] driver: i915 v: kernel 
           Device-2: Realtek Integrated_Webcam_HD type: USB driver: uvcvideo 
           Display: wayland server: X.Org 1.21.1.2 driver: loaded: modesetting unloaded: fbdev,vesa resolution: 1920x1080~60Hz 
           OpenGL: renderer: Mesa Intel UHD Graphics 630 (CFL GT2) v: 4.6 Mesa 21.1.4 
Network:   Device-1: Intel Cannon Lake PCH CNVi WiFi driver: iwlwifi 
Drives:    Local Storage: total: 476.94 GiB used: 65.46 GiB (13.7%) 
Info:      Processes: 296 Uptime: 2h 34m Memory: 15.41 GiB used: 4.33 GiB (28.1%) Shell: Bash inxi: 3.3.03
But the kde "system monitor widget" Total CPU use shows results for 8 cores.

I'm curious about the discrepancy, and I wonder who's lying to me - Dell or KDE! Does anyone know why this should be?
Thanks in advance.

Quad core, but 8 threads unless you turn off hyperthreading, the system monitor gives you total threads, not just cores. IE - my 8650u is also a quad core, but shows 8x Intel Core i7-8650U in KDE due to having hyperthreading active.

One is probably getting cores, the other threads. Try 'sudo cat /proc/cpuinfo |more' and see what the kernel thinks. Another thing to do is google the exact part number, and that will tell you what intel thinks.

Ah, thanks Bus-Kid. Lots of info there, and I'm still looking through it. But it clearly says that there are 4 cpu cores. You're probably right about core vs thread count.

He is. lscpu is a bit easier to remember and type than sudo cat /proc/cpuinfo, but the output is essentially the same, main difference being lscpu only lists the data for the first "CPU" instead of as many times as there are "CPUs". "CPUs" combines actual cores plus threads, each of which are listed separately.
