HP Z8 performance issues

[jeanmichelb98871918]

Hi all

Did someone have tested the HP Z8G4 with AE ?

I have performance issue while rendering.I got 64GB of RAM and a P4000 Graphic board and a 20 Core of 2.2GHz proc

The render is slower than in a MacPro 2013 with 32GB of RAM and D700 graphics ... don't understand why

Thanks for your help

Well, you apaprently never wasted a thought on how AE works or for that matter video processing in general. Many processes are strictly linear and cannot be parallelized, so additional processor cores will barely ever used and. More cores = less efficiency per core and in fact Xeon processors even run at lower clock speeds than coreXi processors and are not nearly as good with TurboBoost and other such stuff.  You simply bought the wrong machine for AE work.

HI Mylenium

We did some tests with another HP and we saw that the Z4 6 cores 3,6Ghz works better.

Did you think that if we use a Z8 4 cores 3,6GHz it will be better ?

the less Core seems to be the solution no ?

Thanks for your answer

It's not the number of cores; it's the speed of the cores that matter.

3.6 Ghz is going to blow away a 2.2 Ghz processor regardless of the number of cores for a lot of AE stuff. Now, some things in AE are multithreaded (the grain effects and the camera shake deblur, for example), but generally speaking you want high clock speed instead of many cores.

Hello Chris,

I understand you!

We have the same tests with HP & SuperMicro and Multi-GPU.

Mylenium and Szalam are ADOBE people,

You have to say what you say!

If I can render on the same machine where AfterEffects is slow,

Blackmagic DaVinci Resolve can render very, very fast

(Test rendering of ProRes 422HQ in h.264)

DaVinci 160fps AE 12.5fps

then I need no statement from Mylenium and Szalam that we have no technical idea.

The problem is, that ADOBE no invested our rental fees for years

to work on the problems.

Now these ADOBE employees, trying with talking, to say it's good.

I agree.  I say Adobe is much more interested in developing new features to attract new renters than it is in making the software they already have work properly for the existing renters.  I have never heard or read anything from Adobe to dispute that.
