128 PCIE lanes? That's just banana's.

Guess I won't have to look for which USB port is 3.1 anymore and can finally throw away all those dirty SATA drives.

Now if only I used some type of software that would actually see benefits from 8-channel memory...

I think the bigger problem is some folks (like myself) simply won't buy Threadripper until motherboards offer all the features I'm actually looking for. The chips themselves are great, but the board solutions have been gaming-centric and are, in my mind, incomplete without official ECC support. I suspect this will not be an issue this coming generation and I'm particularly curious about the WRX80.

Official ECC support since April 2018. Done.

Not that it matters. Epyc and SP3 boards do not cost much more than Threadripper/X399, and then you get to use cheaper buffered ECC, and much more of it.

Why would you go TR over Epyc in an application where ECC is necessary?

(actually asking, I have no clue)

I apologize, my post was not complete.

Clock speed and cost would be the two primary factors. While Epyc motherboards are priced reasonably well, equivalent (or near-equivalent) 1P chips are notably more expensive than their (faster) TR counterparts. Additionally, the need for ECC compatibility is not necessarily (for me, at least) an immediate concern. A few years down the line as I inevitably replace this hypothetical computer it would probably become my home server. Of course, plans change and all that, but I like having the flexibility - especially at the price point we're talking about.

The Designare has actually been in my watch list for a while now, but I'm 'hoping' to find a board with 10g and a somewhat less ostentatious design. With the exception of Asus, I'm concerned about the ability to shut off all the RGB lighting on these boards without needing to install proprietary software. I know Asus lets you manage it within the BIOS and AsRock seemingly does not (at least I haven't found it yet), but I don't know about other brands.

The Designare has a whole one RGB, on the SB, and can be disabled/changed in BIOS without software.

Forget 10G as a board feature entirely. 10GBase-T (the only 10g they put onboard on consumer boards) is a bad and expensive path to go down with no future. What you want (provided you have not already paid into CAT6) is SFP+, as there is a lot of SFP+ gear for cheap on ebay, as well as QSFP+ (40g) because businesses are upgrading from 10g/40g to 25g/100g. You can pick up a Intel X520-DA1 (or DA2) for like $40-50, fibre itself is actually cheap, and so are 10g transceivers. ...Or if you're like 10ft from your switch you can just buy a $10 DAC and not deal with any of that.

Good advice! I really like my 40GbE LAN using Ebay hardware.

We need to drop CAT to get > ~5GbE in a practical way, this is why 10GbE is still not really standard, we want to keep CAT and it is not really good enough for 10GbE even today. If I were to get on-board 10GbE I would want it to use SFP+.

Thanks for the input you two, that is certainly something worth considering.

EPYC is primarily aimed at the server market where performance-per-watt is king. In the desktop market, efficiency is sacrificed for outright performance - which tends to suit desktop-class applications where workloads (such as rendering, software compilation) benefit from the increased clock speeds on offer. If AMD only wanted EPYC in high-end desktop and professional workstations, Threadripper simply would not exist.

Know whats faster than a 3.0Ghz 32-core in an application that can make use of 32 cores? Two 2.25ghz 32 cores. Threadripper does not hold the performance crown over Epyc.

Threadripper exists as a medium ground between people who need more, but don't need everything, just like Intel's HEDT. Also just like Intel's HEDT, it does not have some features that are considered important to workstations, such as buffered ECC. AMD has no reason to allow Threadripper to directly encroach upon Epyc's space when you can buy Epyc for just that little bit more.

Why would AMD shoot Epyc in the foot when they have no reason to do so?

To put it in context and clarify, I got;
  • An IBM Blade G8000 with 2xSFP+ expansion card for $100
  • An IBM Blade G8124 for $400
  • Two 75ft cyan multimode fibre cables for $25
  • Four Arista transceivers for $40
  • Four X520-DA2s for $130
  • Six 3ft Dell DACs for $30

This allows my two desktops to be connected at 10g, my gameserver connected at 10g, my main server to be connected at 40g (4x10gs, it's ESXi so servers are split between the NICs), and my PFSense box connected at 10g, with everything else including wifi connected at 1g (which connects to the G8124 via 10g).

Enterprise hardware does come with compatibility concerns to keep in mind, but the potential for upgradeability is far higher if that is a route you want to go. Most people do not need a 24-port 10g switch, but if you can work with a 24/48 1g that has a SFP+ uplink or two for your server, that can be had really cheap.
