Hello,
I am trying to build the most powerful VMix Machine "in the World" and could use your help so we know exactly how VMix is using the CPU and GPU efficiently.


We are currently using a Dell workstation
GPU: Nvidia Quadro RTX 6000
CPU: Xeon E2276G 6 core 3.8Gh
Hard Drive: Intel Raid 1 Solid State
2, 10Gb Network card: we are using Link Aggregation for 20Gb of network speed.

We can currently take in 20 clean NDI fees at 1080p without any jitter frame drops or issues.
we create complex Multiview within Multiview builds with lower thirds and transparent graphics

Our goal is to create a system that can take in 30+ NDI feeds at 1080P with complex builds.

upgrading our GPU to RTX8000 for more ram (48Gb)
upgrading our Network card to a fiber 40Gb card
Upgrading to PCI solid-state drive
still deciding on the CPU. Would you recommend a CPU that has more cores over speed? We are stuck in the Xeon World using the Dell workstations so wondering what you might suggest.


We can also run a duel CPU setup. Can vMix utilize 2 CPU's effectively?
Were looking at
Duel intel Xeon Gold 6244 8 core 3.6Ghz (4.4Ghz with turbo)
or
Duel intel Xeon Gold 6246R 16 core 3.4Ghz (4.1Ghz With turbo)

We don't need instant replay. Our main concern is Native NDI inputs and Multiview Builds.

I'm looking into something similar like this for an all NDI workflow and a few things don't make sense.

You are using a SINGLE CPU and can take in 20 clean NDI feeds at 1080p?

on a cpu that only allows for a maximum of 16 PCI-E lanes?

Please share with us your CPU and GPU utilization along with your network NIC utilization....

What does pcie lanes have to do with NDI feeds? I routinely use close to that and rarely exceed 50% CPU usage on an i9-11900k and RTX-3080 and a single 10g NIC.
