ART: AMD Ryzen 7 PRO 3700 vs 5700X

I use the ART raw image processing program. And its speed is important to me.

Recently I changed my CPU: I replaced an AMD Ryzen 7 PRO 3700 (very similar to 3700X, Zen 2 based, 8 cores, 3.6/4.4GHz) with an AMD Ryzen 7 5700X (Zen 3 based, 8 cores, 3.4/4.6GHz).

I wanted to measure the speed difference in ART. So I prepared a 3.5GB image set: 107 raw files (ARWs from the Sony a7c and DNGs from the Ricoh GR).  I used optimized versions of ART: 1.24.1-14-g3eebab7b1 (Znver2 - optimized for Zen 2) and 24.1-14-g3eebab7b1 (Znver3 - optimized for Zen 3).

Best times (more images per minute is better):

PRO 3700 & Znver2: (377s) ~17.1 images per minute

PRO 3700 & Znver3: (379s) ~16.9 images per minute (just for reference)

5700X & Znver2: (330s) ~19.6 image per minute

5700X & Znver3: (330s) ~19.6 image per minute

So the performance gain is about 14-15%.
