I’m currently running a Xeon E3-1231v3. It’s getting long in the tooth, supports only 32GB RAM, and has only 16 PCIe lanes. I’ve been butting up against the platform limitations for a couple of years now, and I’m ready to upgrade. I’ve been running this system for ~10yrs now.
I’m hoping to future proof the next system to also last 8-10 years (where reasonable, considering advancements in tech and improvements in efficiency), but I’m hitting a wall finding CPU candidates.
In a perfect world, I’d like an Intel with iGPU for QuickSync (HWaccel for Frigate/Immich/Jellyfin), AND I would like the 40+ PCIe lanes that the Intel Xeon Scalable CPUs offer.
With only my minimum required PCIe devices I’ve surpassed the 20 lanes available on desktop CPU’s with an iGPU:
- Dual m.2 for Proxmox ZFS mirror (guest storage) - in addition to boot drive (8 lanes)
- LSI HBA (8 lanes)
- Dual SFP+ NIC (8 lanes)
Future proofing:
High priority
- Dedicated GPU (16 lanes)
Low priority
- Additional dual m.2 expansion (8 lanes)
- USB expansions for simplified device passthrough (Coral TPU, Zigbee/Zwave for Home Aassistant, etc) (4 lanes per card) - this assumes the motherboard comes with at least 4-ports
- Coral TPU PCIe (4 lanes?)
Is there anything that fulfills both requirements? Am I being unreasonable or overthinking it? Is there a solution that adds GPU hardware acceleration to the Xeon Silver line without significantly increasing power draw?
Thanks!
I think the 3rd Gen epic and threadripper were the first ones with pcie gen4. You might want to look at something a little newer if you’re wanting to get 10 years out of it. I’m personally looking at trx50 and a 7960x, but still saving up for that $1300 processor
The options I’m looking at have PCIe 4 and seem to be gen 2? Epyc 7282 or 7302.
I didn’t realize that, and it looks like you’re right, that could be a good deal
