Cross-check of /proc/cpuinfo

[Jeffrey Walton]

Hi Everyone,

I purchased an HP Envy 17T during Amazon Prime. The machine is spec'd
with a Intel Core i7-13700H: 6 performance cores, 8 efficiency cores,
20 threads total. <https://www.amazon.com/dp/B0CCZ3XFBX> and
<https://ark.intel.com/content/www/us/en/ark/products/232128/intel-core-i7...;.

I installed Fedora 38 with the KDE spin. I did not bother to boot to
Windows. Secure Boot = Off, and away I went...

When I cat /proc/cpuinfo, I see the model name "Core i7-8700" with 12
cpu's. I do not see a model name of "Core i7-13700H", and I do not see
the 20 cpu's.

The "Core i7-8700" is unexpected to me. I'm pretty sure the wrong
laptop was shipped. But this is my first 13th gen machine with
performance and efficiency cores. I did not see any kernel bugs that
would cause it to display the wrong model name for 13th gen
processors.

Can anyone verify cpuinfo should be displaying a model name of "Core
i7-13700H" and should be showing 20 logical cpu's, please?

Thanks in advance,

Jeff

I don't know for sure but search for i7-8700.

Mine 13 reports like this:
vendor_id       : GenuineIntel
cpu family      : 6
model           : 186
model name      : 13th Gen Intel(R) Core(TM) i5-1335U

And I can see the different speed cores.

You might do a lspci and look at the hardware, that will be a dead
giveaway that the hardware is not what it is supposed to be.

And I will not order a laptop from anyone except Amazon on Amazon.
Looking through the 3rd party vendors descriptions makes me question
everything about what they are really selling.  I have seen it say
"new 2023 laptop" and have a cpu from 4-5 years ago.

Note a i7-8700 is a coffee lake from 2018 and does have 12 cores.
See https://en.wikipedia.org/wiki/Coffee_Lake.

Anyone on amazon that says xxxx year laptop and xxxx is this year or
last year seems to be trying to pull a fast one (now it is possible
that some are not, but last time I looked the 3rd party laptop sellers
appeared be a pretty unreliable bunch just based on their
descriptions).

Jeffrey,

Did the vendor/amazon fix the mistake you had with your laptop
appearing to be the wrong cpu?

Yes.

I have a laptop with i7-13700, /proc/cpuinfo shows 20 cpus and displays 
the model string correctly. The file is quite long so I attached to my 
pastebin: https://post.karuboniru.uk/61766783-2b89-4872-a589-816ced91a876
