About the Obtanium reference system.

I am wondering why the w5-2565X CPU is recommended instead of the w7-2575X

The latter has 4 Cores plus 22 vs 18, which would allow more NDI IP flows. Apart from incorporating more cache memory. It is true that the base frequency is 3 GHz compared to the 3.2 GHz of the w5-2565X.

But the previous top CPU reference system was an i9-10980 XE with a base frequency of 3.0 GHz and it was the recommended one.

Summing up. Isn't a w7-2575X better than a w5-2565X if there are no budget problems?

Excuse me for telling you that precisely that processor that you indicate would not be suitable for vMix at all. The reason is the very low base frequency. Since this CPU has so many Cores, its clock must be quite low. Very powerful but with low operating revolutions like the Diesel engine of a freight ship.

w5-2565X - 3.2GHz
w7-2575X - 3.0GHz
I9-10980XE - 3.0GhZ
w9-3495X - 1.9GHz

Vmix needs high base frequency, from what I understand.

This is precisely the debate I want to open here. the importance of clock frequency compared to other characteristics of CPUs


Similar to the graphics card debate. The importance of memory bandwidth or the number of CUDA cores compared to other characteristics of GPUs for vMix

personally, for 200 mhz I would opt for more cores

Question. Has vMix Official recently announced any tested configuration of the latest generation that does not care about price but about maximum performance?

For example with Ryzen threadripper or without leaving Intel with a w7-3565X CPU that with the same Gigabyte MW83-RP0 motherboard of the Obtanium reference system could allow the use of 4 BM Decklink Quad2 capture cards to achieve 32 SDI ports with a thin graphics card like the upcoming RTX 5090 Founder Edition?

I open a debate

Thank you. I didn't know the video.

I understand that the reference system is the best power-price ratio.

But without a doubt, if the budget is not a problem, a better machine can be made without having problems with fitting parts or cooling.

It would also be good to know if they have done very long-term stress tests with that Gigabyte MW83-RP0 board. Lest they recommend a motherboard that has a short lifespan because it is more poorly built compared to direct competition. Its lower price lies partly in this. For example, comparing with an Asus PRO WS W790E SAGE SE (Intel) or Asus Pro WS WRX90E-SAGE SE (AMD) with more perceptible quality.

rather an AMD Ryzen Threadripper PRO 7985WX if you want to stay on a base frequency of 3ghz minimum as above

and an Nvidia RTX 6000 ADA instead of the 5080/5090

on the official AMD website, the base clock of the 7995WX is 2.5 ghz

if you stay on your low cpu minimum at 3 ghz
you invest the difference between the cpu in rtx 6000 ada

and if you want to make a max system, you don't count the money anymore

unlimited encoders for rtx ada
and in your list you forgot the m2 pcie 5.0 x4 ssd

8 encodes can easily be covered if we do 4 camera multicorder+record pgm and 4 streams we`re over the GPU driver as now we have the ability of 5 streams. But also quadro that says unrestricted is only in theory. In practice for example i have quadro p4000 and it says un-limited encodes but in practice is not true. So in practice maybe a quadro can do 10 1080p? i dont believe that it can do even the new 5000 series quadro for example 10 cameras and 5 streams and record. Maybe 3-4 years back when the GTX-RTX drivers allow for 3 hw encodes,quadro cards was more meaningfull for Vmix shows with more than 3 encodes and max 8 but now is not this the case.
For decoders.. It is other story in my opinion. At first this will only have effect only for SRT and NDI HX. There yes it will be used. BUT.. for full NDI or Video playing the GPU decoder is not used. So there for a workflow like this,CPU is important
