Calculation performance issue


#1

Hi guys,

I build a new system for Maya. But I have some performance problems and I try to understand what is wrong!

My system:

Windows 10 Pro 64
Asus ZE10PE-D8 WS Motherboard,
2 x XENON E5-2683 V3 CPU (2 GHz, total 56 Thread),
EVGA GTX 1080 TI Founder Edition GPU,
4 x 8 GB Kingston 2133 MHz ECC Ram,
Sandisk SSD

My old system:

Mac OS X El Capitan
Macbook Pro 15" Retina (2012)
i7 2.7 GHz CPU,
16 GB Ram,
SSD

When I use Arnold Renderer on Maya 2017, Windows PC 5 times fast from Macbook Pro for single frame.

But when I try nParticles, Mash or Realflow, Windows PC calculation speed very slow than Macbook Pro.

In Windows PC CPU usage values about %5 - %20 and when I press play, every frame I waiting a long time on Windows PC.

I render simple grass video with 200 x 200 grid distribution type, on Windows PC, 180 fps Arnold render only 2 times fast than Macbook pro. I know, resolution, polygons count and many other parameters change calculation time but I open same project file on each computer and same version Maya.

Also I try Realflow 10 and I get same performance issue.

What is my system problem? Any ideas?

Please help me.

Thanks.

Those Xeon chips aren’t very fast for single-core processing. As you can see, it’s running at 2GHZ vs. your old Maxbook running at 2.7GHz. Both are extremely slow by today’s standards. Having all those cores in the dual-Xeon setup is cool and all but still not going to be as fast as a new i7 or R7 chip in single-threaded calculations, and many of these are still single-threaded. Especially nParticles and other dynamics which aren’t easily parallelized.

Keep the Xeon as a render slave and build a main workstation with an i7, i9, R7, or R9 instead. If you go with the Ryzen chips you will spend just a fraction of what that Xeon setup cost already, but those chips are really new so maybe the i7 would be better for you. A desktop i7, not a laptop one obviously.
