In short, if I were to get a 12600k, how could I get the igpu and 2.5g networking to work correctly?

will need unraid to be on 5.15 kernel to support 2.5g. igpu is supported with info above.

Are you happy with the power consumption? Most reviews target on full load but not on idle/low load which is more important in the Unraid context.

For me on the 12600k it looks pretty good in idle - better than the ryzen 3600 with a x570 mobo i used before...

Whole system power usage in idle is about 75watts and was about ~85-90watts and before i only used 2 Sticks of DDR4 Ram instead of now 4 Sticks

I think it could be better with undervolting but I prefer stability and don't want to invest time into finding a stable voltage..

 

And Idle for me means 10 Docker Containers running and 1 Windows VM with a dedicated GPU always on - the vm uses 6 P-Cores and most of the running docker containers share the e-cores

I would actually love to see what the power would be like with the Windows VMs turned off and Unraid just running on the E cores, and the transcoding done through the iGPU 🙂. I would love to see if it get anywhere near my current i9 mini nuc unraid server which runs at ~20W with 10 dockers and 24TB of NVMes

I'm hoping that I can just get some clarification that I'm not off base with my understanding. Quick background, I have a existing unraid system that is in desperate need of upgrading. My vision of a build aligns closely to what Blobbonator is running. 

 

I'm hoping to run an i7-12700k with the following workloads:

Daily driver/Gaming VM: 8 P-Cores with an older GTX 1070 passed throughs

Unraid and Dockers (Plex primarily, with max of 3-4 transcodes, but hopefully room to grow by a couple if necessary): Using the E-Cores and iGPU for Plex transcoding

 

If I read correctly, the iGPU will work fine following the steps outlined above and that currently the only potential drawback would be the lack of support for 2.5Gbps, until Unraid moves to 5.15 for the kernel (Does this mean the onboard NIC won't work at all, or that it won't run at 2.5Gb? Will I need a separate 1Gb NIC in the interim?).

This may depend on which motherboard you go with. Currently with the MSI PRO-A DDR5 I have the NIC is not detected, so using USB Ethernet adapter at present.

Alright, which isn't a terrible work around for the interim. 

 

Otherwise, there isn't any glaring issues with what I'm expecting out of the hardware? The E-Cores should be able to handle the load of Unraid and my Dockers and the iGPU should have no trouble with my plex transcodes and then some?

Yes I think that will be a viable setup.

At the moment as far as I know there is no HW support for transcoding with the igpu. At least I tried all the gen11 tricks that were mentioned on reddit and this forum and none worked for me.

 

Just for clarification I run (Spare parts from old systems for GPUs and RAM):

Intel 12600K

48 GB of DDR4 3000MT

3x 8TB Samsung QVO SATA SSDs

2x 512GB NVME SSDs

Quadro P600

GTX 1650

Ethernet Dongle (same issue as mentioned above)

ConbeeII USB Stick, Logitech Wireless Dongle

3x 120mm Noctua Fans

1x 40mm Noctua Fans

2x 92mm Noctua Fans

Yeah a lot of fans but the Server is right beneath my TV so it should be whisper quiet.

I have  setup Plex on my Test server and HW decoding does work, but I did get a Call trace and Lockup whilst testing, so the I915 driver may not be 100% stable.

How did you manage to get the alder lake gpu to transcode I tried al the above settings but my 12600K doesn't use the igpu in plex. with the igpu is listed when i use cd /dev/dri and then LS and also intel_gpu_top seems to see the gpu but no luck on getting hw transcoding to work yet.

System info:
intel core i5 12600K
Gigabyte Z690 UD DDR4

64GB DDR4 3600Mhz
10x 6TB HDD (Array)
3x 1TB SSD (Cache + vm pool)

Which OS vers are you running, I am running 6.10RCs.

 

If on 6.10 you need to blacklist driver so Intel_Top loads with correct options.

 

echo "blacklist i915" > /boot/config/modprobe.d/i915.conf 

 

And added driver to Docker.
