Ryzen 9 3900x with dual GPUs??

[Fainted88]

Hi

 

I am building deep learning machine for my home. I am planning to use AMD ryzen 9 3900x with Nvidia Rtx 2080 to or other low end in RTX series which has NvLink support. Also I would use 1tb SSD with NVMe with 4.0 for fast transfer. 4 tb HDD for higher data.

 

I currently am planning to have just one GPU but would like to expand and add additional GPU after some time.

I know ryzen 9 has 24 PCIe lanes. 4 will be used for chipset/CPU. 

 

1.My query is will the ryzen 9 3900x be able to handle 2 GPU/ dual GPU configuration?

Lane bandwidth can be sacrificed, I am more concerned with compatibility with the CPU and motherboard

 

2.If it (3900x) can't support 2 GPU s, should I go for Threadripper 3960x which is quite expensive at this time?

 

3.How much of Lane bandwidth is required for all of them combined, will it suffice within 24 lanes?

 

4.Will it support 2 GPU, 1 SSD, 1 HDD, also if the motherboard has in-built WiFi will the Pcie-lanes used in that also?

every ryzen supports sli, you just need a motherboard with a X series Chipset

 

with a X570 you have PCi e 4.0 that has double of the bandwidth

that means 2 RTX Card with PCi e 3.0 uses praticly 16 lanes and you have 4 left

 

I dont think, but i dont know if build in wifi uses PCe lanes

that video can give you more information

You will be 100% fine, sli/crossfire/Nvlink has been around for a while and won’t be an issue, 

However I would advise finding a board with 2x16 pcie slots.

Will there be enough for SSD and HDD??

Also any suggestions for x570 motherboards??

3950x is expensive, I need more GPU as there would be more processing done by it.

Then do a ryzen 7 3700x, asus crosshair viii hero, and a 2080 to. Most programs don’t support sli anyway

The Video was meant for the PCI e part, not the cpu

 

only NVMe SSD needs PCI e

the rest uses the sata ports

NVlink is originaly designed for Workstation use and its diffrent from sli it

it depends hart on your deep learning algorimts/programms what you try to do

from Minecraft baritone Bots, i only know that more cores/Ram/GRam is better
