First of all I want to say hello to you all, I just signed up to the Forum. I'll start by saying that I've read a lot but I'm still very confused and for this reason I explicitly ask for help.

So far I have tried to recycle the hardware I own and buy (budget permitting) what I need. I need to setup a 6-camera SDI vmix system (Sony Fs5) to stream to YouTube at 1080 P25.


As for the acquisition I have a Sonnettech Echo express SE II (thunderbolt 2) with a Blackmagic decklink quad and a Blackmagic decklink duo 2 inside.


So far I've been playing around using a 2013 Macbook Pro with Bootcamp and Windows 10 + vmix installed as a computer. The computer is equipped with an Intel i7 quadcore and an NVIDIA 750M if I remember correctly. The performance with 4 cameras was sufficient but the computer was too old and no longer reliable. For this reason I wanted to switch to a native Windows PC. I would prefer a Notebook for portability reasons but, even reading a lot online and here on the forum I haven't found a definitive answer. I would like a Dell Precision because I trust the brand which is very widespread and serious. However, I don't know how to choose the features I need on the used market. I imagine that the minimum essential is an i7 but perhaps an i9 is better, as regards the NVIDIA card I really don't know because I'm very confused. What I need to get is listed below:

1) Mix and cut with 6 SDI camera at 1080 25p

2) Streaming on youtube at 1080 25p

3) Output a program signal using hdmi output (embedded on the computer or using a free decklink output converted sdi->hdmi)

4) Record the Program on the internel SSD

that is the minimum the computer must do.

IF THE computer is capable i like also to record all the camera on the internal ssd but i have read that is cpu intensive? gpu intensive? boh.


thanks for tour reply

The vMix Reference Systems are the best guide for knowing the type of computer to use with vMix:

The System Requirements for vMix Instant Replay are also a good supplement as a guide for what is needed or recommended in higher end systems to use that feature effectively:

Given that, the Dell Precision 3541 you list is a little on the weak side, the i7 9850H CPU only has 6 cores @ 2.60GHz and the Quadro P620 has fewer CUDA Cores (512) than a GeForce GTX 1050 (640) which is the base minimum you will want for a GPU (as a comparison, the GeForce RTX 4080 Super in the Obsidian Reference System has 10,240 CUDA Cores).
