I don't know my machine's specs: it doesn't really matter anything off-the-shelf from Circuit City or Best Buy is fast enough for what I do.
I have a windows desktop machine from 5 years ago that I run Visual Studio and dozens of embedded IDEs on.
All my networking / cloud dev is done on three different linux laptops (all Dells that were repurposed): Qubes, Ubuntu, and FreeBSD. (FreeBSD has a few other images on it with Grub including Win10.)
And then I have two macbook pros, an x86 and an M1 that I remote desktop/VNC to the other machines.
I prefer laptops because they take up less space and are portable.
By embedded I mean products based on Arm Cortex-M and -R, Renesas RZ/RL/RX, TI 430, Synopsys ARC, PIC, Atmel, etc...
