Anyone seen the new line of CPU from Intel, the 8th generation. Thoughts on it in vMix, is it worth going with that over the 7th gen 7700k in the reference system page? If there will be a significant increase in performance, perhaps its worth it.

I don't see much benefit in those extra cores or the marginal increase in clockspeed you can get with those new i7's, since the new cpu's stay limited to 16 pcie lanes.

I just started using a z270 ws (plx chips) with a 7700k, and the cpu (cores, clockspeed) is not a bottleneck in the system. It might be useful if you want to run other programs alongside vmix, but otherwhise the only real upgrade is to x299/i9 in my opinion.

For the new i5 and i3: since they don't have hyperthreading, I don't think they are very useful, except for low budget/input systems.

Great CPUs, but unfortunately no extra PCIe lanes.

While 7700k performs quite well, I was able to "bottleneck" it for a few of my productions. Weird part is, it doesnt go all way up 100% cpu usage, so I'm guessing VMIX likes cores / threads.

The question you have to answer here is: what are you going to do with VMIX? What are your needs?

In my case, the heavy production only worked flawlessly with X299 + i9.

How do you define "heavy" productions? According to the reference system, the i7 7700k should be able to handle 8 SDI inputs as well as replay.

Camera inputs isn't my main measurement system for VMIX.

My heavy production has over 120 inputs, 8 sdi cameras, 5-10 NDI inputs, 20+ videos, 5-10 XAML sources, recording, streaming, 2-3 ndi outputs, etc.

over 120 inputs - as in video files / images / lower thirds etc?

Is this all running smoothly off of a single x299 i9 build?

correct. 1-9ms render time / up to 15% CPU usage..

GPU usage goes up to 30% with 3GB VRAM used (gtx 1070)
