7z trivia

The i5-4590 showed up yesterday and I put it in my old Dell box. I was
looking for a quick and dirty benchmark and found 7zip has sort of an
Easter Egg.

'7z b' will do a test of all cores and threads, while '7z b -mmt1' will
do 1 thread using compression/decompression.

I wasn't surprised that the Ryzen 7 4700U box with 8 cores is faster than
a Core i5 with 4 cores, but testing 1 thread on each shows a slight
advantage to the 2 GHz Ryzen over the 3 GHz 4th gen i5.

I don't know why but the Windows 11 laptop with the Ryzen 7 4700U is quite
a bit faster decompressing.

I'm less familiar with AMD processors, but if I'm not mistaken, the
one in question is quite a bit newer than the Intel one, right? When
I bought a first gen quad-core i5 in 2010 for my old computer, it was
pretty high end, but replacing it in 2021 with a 10th gen six-core i5
was more mid-range, despite being kind of comparable relative to their
eras. It's a dream CPU for me, and yet wasn't particularly expensive.
My motherboard was the real "high end" component I invested in, other
than the 650 watt power supply. The SSD was a pretty nice one at the
time, too, still serving me very well. And now it's running Linux
Mint Cinnamon, not Win11. What a great blessing.

Yeah, the Ryzen 7 4700U is from 2021, the i5 is from 2013. It's an old
Dell box with a 1150 socket so the i5 was a step up from the original 2
core Pentium for a massive $17. It started life as Windows 7 but that was
very seldom seen after I installed OpenSUSE 13.2. Some of the Broadwell
(5th gen) processors fit the 1150 but there is no real advantage. Same
architecture as the Haswells except they went from 22 nm to 14 nm.

It's my hack around with Fedora box.

Yes. With the one thread flag it reports like below. On Windows I had to
hunt it down in C:Program Files\7-Zip\7z.exe. For all 8 threads it says

For about $2000 I'd want it to feed the cat too. A $17 4th Gen works for
me.
