    Workstation choice between CPU vs RAM and GPU

    Gino Post

      Since CC 2015 Aftereffects doesn't utilize all the CPU power and the memory to CPU core ratio has been changed.

       

      I wonder what workstation would be the fasted in CC 2015 and future releases in rendering and preview.

       

      A HP Z440 with 128GB RAM, Quadro K5200 and 8Core 3.2Ghz CPU

      vs HPZ840 with 64GB RAM, Quadro K4200 and dual 10Core 2.6Ghz CPU.

      • 1 x SKU: F5G73AV HP Z840 Workstation 1

      The price difference is €1000.

          NO way to answer this question without knowing about the application, the source material, the export format and the typical workflow.

           

          The first system has almost too much memory for an 8-core system, the 2-nd one has not enough memory for a 20-core system. Both have very pricey and underperforming Quadro cards. Both lack sufficient disks. You would be better off (price- and performance-wise) with a custom build PC, instead of these HP systems.

            Source material is camera rushes in HD (XDCAMHD) and 4K(XAVC). The export format is HD in XDCAM HD.

             

            The workstations are connected to a central NAS for collaboration. Each workstation has a preserved bandwidth over 1 gb to this nas.

             

            The typical workflow is for broadcast video editing and compositing.

             

            Would the following be a better balance between CPU, RAM and GPU for Adobe premiere and aftereffects?

            CPU = 2 x 8 core Xeon

            RAM = 64GB

            GPU= NVIDIA QUADRO K6000

             

            What custom build spec's would you use?

             

            Thanks,

            Gino

              fastest in the crippled cc2015 and fastest in future fixed versions will be two different things. as you stated, AE cc2015 has been changed and the memory usage requirements will be lower going forward, but when AE will fully be ready is unknown. you will also need to decide if doing ram previews or disk cache previews, to determine how much memory you need. if you plan on keeping these workstations a long time, you may want to focus on the best computer for future versions of AE when its fixed. the dual cpu system is a fair amount faster of the two systems you list and should work best if using cc2014 multi-processing to render. if you plan on replacing these systems within a year or two, you may want an i7 based pc to get the highest clock speed. if these are dedicated AE only machines, the graphics card doesn't need to be very powerful unless using third party gpu plugins. the AE team announced they are going to slowly add gpu based processing features, so for now even the quadro k4200 should hold over for a good while, and could be replaced with a gtx when needed.

                The Quadro range is overpriced and under performing. For a fraction of the price of a K6000 you can buy a GTX 970 that is much faster. Price/performance wise the GTX 970 gives 10 times more 'bang-for-the-buck'.

                 

                Since AE is not good at multi-threading, a single i7-5960X over clocked to 4.5 GHz easily outperforms dual Xeon 8-core systems.

                  Dear CC_Merchant,

                   

                  For the same reason I've tried the GTX970 card. Even in the GeForce product range this gives the most performance/price ratio.

                   

                  However in practice when using raytracing in AE the application throws errors to the user and doesn't do the rendering.

                   

                  This card GTX970 and any of the GTX9xx series are not tested by Adobe.

                    The GTX 9xx do not work with the obsolete Ray Tracing. If that is important to you, look at the GTX 7xx series.

                      Adobe is adding support for the 900 series cards in AE Ray Tracer. However they have stated in the past Ray Tracer is basically legacy and they will continue to build on the C4D link. The codecs you list would perform better with higher clock speed with less cores than lower clock speed and greater cores. I would also suggest a 5960X over the Dual Xeons. AE will still use a significant amount of cores and threads depending on the media and FX user. It uses a massive amount of ram even still. So you definitely want atleast 64GB of ram if you use AE quite abit.

                        It seems that C4D renders utilizes all the CPU cores.

                         

                        In this case a 5960X will be much slower than a 2 x 8 Core XEON system.

                         

                        Using only an AE composition without C4D the 5960X will be a bit faster.

                         

                        But can we assume that in the future Adobe will un-cripple aftereffects?

                          Wrong. See Tweakers Page - Single or Dual CPU

                           

                          Even the pretty pricey E5-2667v3 (€ 2320 each) will be around 10% slower in dual CPU configuration than a single i7-5960X @ 4.5 GHz in a perfectly multi-threaded world and cost 4.5 times more. AFAIK we're not living in Utopia.

                            Ok,

                             

                            Accordingly to this graph a Dual 8 core system with E5-2667v3 CPU is approximately 8% faster than the single i7-5960X.

                             

                            But the BFTB is indeed not completely not comparable.

                              If you get Octane for C4D then the GPU acceleration will perform better with the 5960X versus the Dual Xeons. C4D without GPU acceleration will utilize all threads the system provides so a Dual Xeon is the ideal choice without GPU acceleration. However that is one of the few applications where that is the case currently. So if you are building to Adobe and C4D then I would suggest the X99 and 5960X with Octane.
