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?

Hi,

w7-2575X is a bit more powerful than w5-2565X.
vmix gives a minimum reference system.
nothing prevents you from taking more powerful components.

nothing stops you from opting for the w9-3495x if you have the budget

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

i too have been curious about these two processors.It would be great if someone can confirm if the .2Ghz drop in w7-2575x processor speed will impact performance negatively. I very much like the w7-2575x for the extra cores as I lean more towards an NDI workflow.

personally, for 200 mhz I would opt for more cores

You are likely fine with the w7-2575X, it should give you the same or marginally better performance and I believe the main consideration at vMix was to build a system with the "best" performance at the lowest cost (comparable or better than the previous Diamond Reference System with an i9-10980XE).

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

@ Xavi137

To the best of my knowledge, vMix has not tested the current high end Threadripper Pro models (they are crazy expensive), but they were or did spend a lot of time testing the mid-range Threadrippers, however, could not find a system that was "as good as or better" than the previous Diamond Reference System until they tested the XEON W5-2565X.
A lot of that was explained here in the December 2024 "Fun Time LIVE" Show:

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.

It would be very positive for vMix to recommend an official system for maximum broadcast production.

To demonstrate that it is the most cutting-edge product with the most possibilities on the market.



My proposal would be to test an Asus Pro WS WRX90E SAGE SE motherboard, with a Threadripper Pro 7975WX or the next generation 9975WX CPU.

Noctua NH-U14S TR5-SP6 CPU Heatsink

RTX 4090 or RTX 5090 Founder Edition GPU or a third-party version with integrated liquid cooling

Octachannel memory 8x16GB 6800 MHz ECC

SilverStone RM51 5 RU rack box

FA CORSAIR AX1600i ATX

Four BM Decklink Quad 2 to have 32 3G SDI ports

The Asus Pro WS WRX90E SAGE SE motherboard has 6 PCIe 5.0 x16 + 1 PCIe 5.0 x8. Four M.2 5.0 x4 slots. Dual Ethernet Intel 2x10GbE + 1GbE Realtek

Graphic inserted in PCIE_1

The four DeckLinks in PCIE_4,5,6,7



Please correct me if something bothers you. I would almost like to open a new topic
