Was the AMD FX ahead of it time in Integer Performance?

[bonami2]

Had a random idea — ran PassMark on my 13900K as if it were an old FX-9590.

 

I disabled Hyper-Threading and the E-cores to mimic the FX’s setup, just out of curiosity.

Attached is the result. Now I’m wondering: are we seeing real gains in integer workloads over the past 12 years, or has most of the progress been in floating point performance?

Gonna dig into some real-world integer-heavy tasks next. Suggestions are welcome!

 

Top = 13900k

Bottom = 9590

This sounds like an interesting test!  Let us know what you find please.

Left 13900k 8 P-Core 0 E-Core no HT

Right FX 8350 on a Formula Z at 4.7 supposedly.

Geekbench 6

 

Sadly seem like the FX was a lot slower! Still not bad for a 10yo+ Cpu

Neat results.  Expected, but neat.   

It's amazing how quick and snappy those FX chips can still feel today honestly (and how SURPRISINGLY capable they are).  They really do surprise you, even if the benchmark numbers show "bad" numbers.

I think the integer core was fine, a little small, pipelines a tad too long, but then they couldn't have done 5ghz boxed processors and 8ghz world records. So at least there where upsides to the story for sure.

I loved my FX. Such fond memories of my good old Vishera. I still have her sitting in a drawer, missing a pin, but still working.
