hi all,
I was for awile looking for information to decide between 7900x and a threadripper.
Seems that Zbrush likes INTEL cores better than AMD. at leas for now or there is some kind problem with AMD XFR. (hyperthread)
end up with a I9 7900X
and here are the Zbench redsults @ 4.3ghz.
Single Thread Timer= 1.934999
Multi Thread Timer= 0.31
Multithreading performance= 624%
also found some:
AMD Threadripper 1950x result to compare:
Single Thread Timer= 2.624
Multi Thread Timer= 0.490997
Multithreading performance= 534%
I think the issue comes from the fact that AMD is prioritizing core count over per-core performance. Intel's individual cores are some 20-30% faster than AMD's similarly priced chip cores depending on workload, and not everything in most programs is or can be made fully multi-threaded and thus can be held up by too slow of single-core performance, so finding that right balance between single-core performance and core count is important and I think Intel has it right for most content creator workloads, since for highly-parallel workloads, using the GPU is much more preferable, we need the CPU to process those long serial operations.
Hi,
Here's the result I get on 1950x with 32gigs of RAM in 4 slots (3200mhz, timings 14-14-14-34)
(no manual overclock, just xmp for ram to work on advertised speed)
Single Thread Timer= 2.461
Multi Thread Timer= 0.364998
Multithreading performance= 674%
cheers

oh thats better fot the TR.
( I edited my post , the multy thread was 0.31) @ 4.3ghz
@ stock I get
2.1 single
0.34 multy
so is about th same as the threadripper
my ram 32gb at 3200 mhz CL 16. T: 16 18 18 36
Intel Core i7 8700K 3.7 GHz 12MB
Single Thread Timer= 1.94
Multi Thread Timer= 0.54
Multithreading performance= 353%
I would say good value for money
How is the new performance compared to 4r8?
Do you measure similar values?
No, Actutaly im getting totally different values in ZB 2018 about 20% worst numbers
4r8 multy= 3.1
2018 multy= 3.6
, no idea why.
I get pretty much the same result as you in 2018, about 10% performance loss.
Yeah, I also have a significant performance loss. Any words from the devs about this? Can this be fixed in a future release?
Windows 10
Single Xeon @ 2.10GHz
128 GB RAM
Single Thread Timer = 3.413010
Multi Thread Timer = 0.542999
Multithreading performance = 628%
Multithreading IS recommended for this system.
I have the quite same result as you, but single Xeon.Quote:
@eFROSTDouble xeon - Multithreading
build a new workstation and it looks like Zbrush doesn't work with double CPU's (Xeon e5 v4) ? or is it just me ?
loads only one of them and I get 50% load in the task manager on heavy loads
Max threads I can set in preferences is 40 as well
I cant confirm this, because the Max Threads in ZBrush come back to 32 even if you store your settings at Max Threads 16Quote:
@eFROST
We just encountered something like this with another user who had an incredible number of cores. He set ZBrush to use a max of 16 cores per CPU and said it then worked like a champ.
i7 7700k 5.0ghz + 16GB DDR4 3200mhz
Single Thread Timer= 1.785
Multi Thread Timer= 0.575
Multithreading performance= 310%
