Building a 24 thread cruncher

[Dirk Broer]

As every Tom, Dick and Harry can build his/her 16 thread cruncher nowadays by simply buying an AM4 mobo and a Ryzen 7, let's try for the next level:
The 24 thread cruncher.

Goodbye to Socket 940, as there are no mobo's with 12 sockets for ye olde Socket 940.

Socket F:

1. Buy a quad Socket F mobo and four six-core Opteron 8400 EE- or HE-series "Istanbul" of 60-79 Watt TDP.

Socket G34:

1. Buy a dual Socket G34 mobo and two twelve-core Opteron 6100 HE-series "Magny-Cours" of 85 watt TDP.
2. Buy a dual Socket G34 mobo and two twelve-core Opteron 6230 HE-series "Interlagos" of 85 watt TDP.
3. Buy a dual Socket G34 mobo and two twelve-core Opteron 6300-series "Abu Dhabi" of 99-115Watt TDP.

I've read reports of SETI.USA members that prefer the old K10 core over the Bulldozer for performance reasons, so if you want to give Socket G34 a try, go for the Opteron 6100 HE-series.

No Socket AM4 here -yet. This might change with Ryzen v2 or Ryzen v3, as Starship is rumoured to have 48 cores.

Socket TR4

1. Take any TR4 mobo and buy a 12-core Ryzen Threadripper 1920X. [recommended]

Advantages of Threadripper against the Bulldozer-based Dual Opterons is the amount of PCIe lanes and the fact that a single CPU system requires less space. Disadvantage is the fact that the quad-channel RAM dictates that you have to buy the RAM in quantities of at least four sticks at a time. This option also gives you the opportunity to make your cruncher a 32-thread cruncher in time though.

No Socket SP3 either, there are no 12-core EPYCs planned yet.
