From E5-v4 to Xeon W. A worthy upgrade?

Hi folks. I currently have an Asrock EPC612D8 and an E5-2680v4 that I use with 4 GPUs (deep learning workstation).

Now, a colleague of mine has offered 500eur for the bundle cpu+mobo. One upgrade option I'm thinking about is a Gigabyte MW51-HP0 to be bought new for 410 eur, with a W-2150B (ebay, 350eur). So I would spend some 250 eur. Is it worth the money and the hassle?

It seems I'll a modest multi-core boost, but a much more solid single-thread performance:

What do you think?

So am not the only one looking at this...With the trend of the W-21XX and W-22XX CPUs also dropping, I might skip buying more v4s despite the prices now.

From a bird's eye view, single core performance is better and so to is power consumption. You also get more pcie lanes and rdimm and lrdimms work, so I can use existing modules.

Only issue would be getting a good MB on the very cheap at the moment.

All in all, I think I will be content with the LGA2066 platform for my homelab for a while to come.

Also it's a bit hard to get a motherboard with the correct slot layout.. That Gigabyte is the only one I found with enough slot placement flexibility, but it has a PLX chip I don't like, and no IPMI.

Yes and no. Consider that modern GPUs are quite heavy, and they sag even with X16 mechanical.

As for the lanes, you are right: X8 gen3 will suffice even for communication between 4 GPUs
