Hello,

 

For a heavy duty nas, i want at the end to have a setup like :

1 gpu for compute work/virtualization (not my priority)

1 gpu for video streaming

1 10G card

 

I maybe got a deal for an I7-14700F and some DDR5, my probleme is for the most basic motherbord DDR5 i find for socket 1700, the setup of pcle are always like :

1 x 5/4 gen pcle x16 (16 lane)

1 x 4 gen pcle X16 (4 lane)

1/2 x 3 gen pcle x1 (1 lane)

 

I have some questions :

1. For a video streaming gpu, is 4 lane of enough ? i have an NVIDIA Geforce GTX 1060 3GB i can use
2. Is it worth to down to find something in DDR4 instead ?
3. Is there a difference betrween intel and amd arrangement of pcle ?
4. For a 10G card there a 2G bottleneck on a 3 gen pcle x1 (1 lane), is this a total no go ? (my internet go up to 8G max and i will have a other NAS with a 10G)

For streaming usually the builtin IGPU is enough.

No, older Intel are usually worse when it comes to spare Lanes

Yes. Usually AMD offers more lanes to the boards

Total no-go. Most of these cards will not even show up with less than 4 lanes connected. Like HBA they need the bandwidth. There is no option to slow down.

You dont need to calculate the possible max speed, its either 10G or ZERO.

 

Thank for the reply.

If i go for AMD, my goal will be to find one with igpu and discard the thought of using a dedicate gpu ? 

 

Edit :

with some research, the only board i find with 1x16 lane and 2x4 lane is livemixer from asrock

ALL current (7000/9000) AMD Cpus have an IGPU as far as I know. So you do not need the 16x slot and can use it for other things like 100G LAN 🙂

 

There are other motherboards, some even come equipped with 10G Ethernet already. Mine for instance (ASUS ProArt X670E CREATOR WIFI) comes with 10G+2.5G onboard (but both are twisted pair only, so I still use my Mellanox SFP+ card in a slot). These "better" boards usually offer "bifurbication" support for the 16x slots, so it can be split into 4*4x and be used to drive up to 4 additional NVMes in an extra card (there are "up to" 4 NVMe slots onboard already). But beware! read the manuals carefully, there are certain restrictions on using onboard devices and populating slots! Before buy, download the manual and read it carefully. The normal ads won't show you them.

 

Warning: Although it comes close to your desires, I would not recommend "my" Motherboard as a base for UNRAID. It's a typical gaming thing, it does not care about power consumption, this box (inluding fast 16core CPU and a medium fast graphics card) draws 150W when idle and up to 500W when heavily gaming. This is nothing that you like to run 24/7. This box is for film cutting/encoding and gaming only. Even for normal surfing I use a different minipc with just <20W
