Will adding more cores help me!?!

[Matt James]

Guys I need help!

 

I'm using some software called HyperMIll. Its a CADCAM CNC program. Its very CPU intensive when calculating all of the 5 axis cutter paths and machine simulations. Please see this screen shot below of my CPU usage. Will adding more cores me help in improve calculation times???

This screenshot is taken during the calculations?

 

Btw somehow hyperthreading is turned off, turn it back on first

depending on the year of the software, but generally yes.

I think you need hyper threading more though.

It is yes, and your right, let me turn it on and I'll get back to you.

I shall turn it on and see

then it looks like it doesnt scale with multiple cores. More per core speed or even faster memory could be what you need, but not more cores. A workload that benefits from more cores will have high usage in multiple cores at the same time, not all spikey at different times like what you're showing (which is actually the task scheduler shifting to different cores meaninglessly)

I had a feeling of that but I wasn't too sure, so something like a Intel Core i9-9900KS? boost clock speed of 5GHz? What speed memory as well? I have 2666 at the moment.

wonder if you'd get more speed just setting the affinity to less cores

specs of the entire system? Easier to just overclock say, a 9600k (including a board that supports overclocking)

 

Memory speed wise, I'd still do more testing for now first. What settings does it currently run at? You can check this from CPU-Z under memory tab.

So you have XMP enabled?

 

Manually select 2933MHz and 1.35V memory voltage, see if it runs. If it does, try run a task (with known process time on current settings) and see if performance gets any better (shorter time). If it doesn't, this memory is already good enough.

 

Z370P-D3 board is quite weak, but should still be sufficient when your work only hammers 1 core at a time.

XMP was not enabled. I have just put it on, speed is about the same although NB frequency when from 800 to 4000MHz

 

I can't find where to change the voltage and clock speed manually thought? 

 

Please see photos of some more calculations.

between 2933MHz and 2666MHz? What settings does it run at 2933MHz?

Finally a workload that uses all cores and threads

 

Sadly the others are still single core based

 

Then in this case, stay with the 8700 unless you're ready to dish out a great sum of money. Do note that single core workloads still wont see major speed increases, only parts that use multiple cores.

How much are we talking? As this is for work, it may be justified

9900k + Z390 Aorus Elite (to feed the beast's power draw) = just over $600. Throw in a cooler and it maybe more like $700-750. The PSU is also worth a check

Would a 9900KS be better? That cost wont be a problem.

they arent different in overclocked performance, so unless you pay the same I wont bother with the KS.
