Recommended CPU for timetabling

[Liviu Lalescu]

Thank you, cipman, for your report! Good processor! Mine is not dead silent if I run 8 instances (8 core).

Volker will add your results to the first post.

So, are you satisfied with the FET timetables? I invite you to write also about your FET experience, on the dedicated Feed-back board. Or you might have suggestions or other reports.

Thank you! I added the result in the first post. You are at place one now :-)

Your CPU and also your cooling is fine. The junction temperature of that CPU is 100°C. So the CPU should run at full speed with 4.1 GHz if your CPU has only 70°C.
So even with a "better/louder" cooling the speed won't increase. (You might increase by over clocking, but I think the disadvantages of over clocking are maybe too strong).
Also the time of 56s is fine. I expected even 1-2 seconds slower. Why? Because I compared your CPU with Livius Ryzen 2700x in the userbenchmark. FET is a single core software.
Check https://cpu.userbenchmark.com/Compare/AMD-Ryzen-7-2700X-vs-Intel-Core-i5-9400F/3958vs4051
As you can see the Ryzen 2700x got 119 points while the 9400F got 120 points. So pretty the same speed.
Why did you expect 45-48 secs?
Comparing with that benchmark I expect that the Ryzen 3600 is 10% faster. But it would be nice if we get a FET benchmark for that CPU.

"Kind" of an old machine here, Dell Vostro 3500 laptop from 2011 (still running like a charm for daily basic tasks - my favorite machine for meetings and field works):

1min55s on 1st run - https://photos.app.goo.gl/xRvjf3gbBYWuKVbYA
1min53s on 2nd run - https://photos.app.goo.gl/2UbH9U6SSjLMsnAB6
1min52s on 3rd run - https://photos.app.goo.gl/8Wy4HtYaMzohh25X6

Intel i5 M 460 (dual core, 4 threaded) @ 2.528 GHz, locally compiled fet-5.14.3 with Debian GNU/Linux 10 (buster) x86_64, kernel 4.19.0-12-amd64, ran on qt4-default/stable,now 4:4.8.7+dfsg-18+deb10u1 amd64 [installed] Qt 4 development defaults package.

As the cache memory seems to matter for the results, this cpu values are:
L1d cache: 32K, L1i cache: 32K, L2 cache: 256K, L3 cache: 3072K (as seen on lscpu bash command).

I'll try to run the test on other machines (higher and lower specs than this), specially the main desktop I use daily.

Thank you for your kind post, with all these details! Volker will add your results on the first post, soon.

Thank you!
