My main laptop scores 3.3 GIPS, guess 10 GIPS is the bare minimum for a modern CPU.
Wanted to see how my fastest ThinkPad (Whiskey Lake i7-8565U) crunches:

Filename: WhiskeyLake.png Size: 1.16 MB 12-26-2024, 10:43 PM

Only 9.4 GIPS, expected more.

hello Sanmayce
I commented the line that prints the Fibonacci numbers because printing can be quite slow and it distorts the timing of the computations, it took a total of 83 seconds on my PC

Using the superb 'perf' on Linux, the Giga-Instructions-Per-Second come as a good metric how well your CPU crunches bytes (the string arithmetic has byte granularity).

My main laptop scores 3.3 GIPS, guess 10 GIPS is the bare minimum for a modern CPU.
Wanted to see how my fastest ThinkPad (Whiskey Lake i7-8565U) crunches:

Only 9.4 GIPS, expected more.

This is my output

Where do the performance stats come from ?

ASCII forever! Yet, this time one of my descriptions given to Japanese AI text-to-image generator.

I commented the line that prints the Fibonacci numbers because printing can be quite slow and it distorts the timing of the computations, it took a total of 83 seconds on my PC

Hi Jack,
you are right, but the dumping is intentional, if you have (like I) a big Console window then you can see a "filling up" effect as length of F(n) is increasing. In order to bypass the slow console printing I use redirection to a file.

@ahenry3068

You have to install 'perf', this is a must-have for any serious benchmarking since it uses the hardware counters, once I asked the author of stats reporting in Valgrind about proper testing, the author himself told me that he uses software "simulated" counters, so 'perf' rules.

Also, you have to run it in maximum niceness aka priority, see the screenshot.

Let's see how one really fast laptop behaves (using my brother's ThinkPad P14s):

Better, AMD Zen4 crunches at 15.0 GIPS, I was right - anything below 10 is non-modern, ugh.

Using the superb 'perf' on Linux, the Giga-Instructions-Per-Second come as a good metric how well your CPU crunches bytes (the string arithmetic has byte granularity).
