merge speed:AMD 3950x<AMD 3700x<i5 8400k? #824

Before I found the problem, the merge program showed "out of memory" and could not run. After I set the virtual memory to 32GB, it can run normally. But there is a problem with cpu speed:

AMD 3950x<AMD 3700x<i5 8400k

The same model.same dst and merge options with “ super resolution” turned on AMD cpu usage is less than 50% Intel is close to 100%

(3950x>AMD 3700x>i5 8400k when “ super resolution” is turned off, but AMD cpu usage is less than 80%, Intel is close to 100%)

Very strange, isn't it? A better CPU should perform better. At first I thought that 3700x was damaged, and then replaced 3950x, but it seems not

A better CPU should perform better.

depends on task.

try to limit CPU cores to 6 for amd in bios and test

I changed the number of CPU processors, usage and speed have changed:

3700x ：6 processors —— usage : 90%~100% ——merge speed：2.42it/s 3950x:：6 processors —— usage : 50%~90%—— merge speed : 1.25it/s

3700x ：4 processors —— usage : 100% ——merge speed：1.84it/s 3950x:：4 processors —— usage : 50%~100%—— merge speed : 1.07it/s

3700x ：8 processors —— usage : 60%~100% ——merge speed：2.51it/s 3950x:：16 processors —— usage : 10%~20%—— merge speed : 1.24it/s

3700x : 6 processors performs best(usage is stable and merge fast).but 3950x : 6 processors performs poorly.I thought it was processors that affected the ability of 3950x.so I changed the processors of 3950x to 4 and 16, but the result seems to have no logic...

yes interesting result...

High chance that your 3950x is being temperature-throttled. Check your CPU temperatures, if they are at 100c it means you need a better CPU cooler. I'm running a 10700k with a 200W TDP cooler and im doing around 6.5it/s at default settings (not overclocked yet, 70c and 100% usage)

Did you ever find the answer? If so, would you mind sharing it and closing this issue?
