I initially assumed it was intended for an xU server case with the associated high speed front-mounted fans. It's a workstation board though, so it seems not.

On further thought, it might actually help. Since the cooler is rotated then hot air will flow straight up in a standard case. So if the case has vents at the top the hot air will flow straight out. In a rotated case like the FT series it's not such a help.

Yeah exactly - only need one of everything, but it's a much higher cost upfront. It would be a fair few k for a 64 core server with 512 gb of ram and and load of disk, but it was only £500 to build small fast server

ANd maybe better for your electricity bill?

run just one threadripper system with about 6x vm doing some stuff, hosting cloud and other services under one pc vs 6x seperate pc's?
 
Another new model has appeared in the wild allegedly:

https://www.tomshardware.com/uk/new...x-benchmarks-suggest-impending-amd-cpu-launch

Ryzen Threadripper Pro 3975WX benchmarks point to a chip with 32 CPU cores, 64 threads and 128MB of L3 cache, just like the Ryzen Threadripper 3970X. It's unknown if the Ryzen Threadripper Pro processors are compatible with the current TRX40 platform. Before its launch, there were mentions of the TRX80 and WRX80 chipsets in the USB Implementers Forum (USB-IF) registry. The two chipsets were rumored to bring more memory channels and enterprise-level features.

  • Ryzen Threadripper Pro 3995WX with 64 cores, 128 threads, and a base clock of 2.7GHz and boost clock of 4.2GHz
  • Ryzen Threadripper Pro 3975WX with 32 cores, 64 threads, and a base clock of 3.5GHz and boost clock of 4.2GHz
  • Ryzen Threadripper Pro 3955XWX with 16 cores, 32 threads, and a base clock of 3.9GHz and boost clock of 4.3GHz
  • Ryzen Threadripper Pro 3945WX with 12 cores, 24 threads, and a base clock of 4GHz and boost clock of 4.3GHz.
All four chips feature the same ludicrous amount of 128 PCIe 4.0 lanes, rated 280-Watt TDP, and the ability to run up to 2TB of RAM in 8-channel mode supporting unbuffered DIMMS, registered DIMMS, and Load Reduced DIMMs. NEW SOCKET!

3955XWX sounds immense.

Has that been confirmed? As far as I can tell, they're just high-frequency, high power Epyc chips.

They use a specialised single-socket WRX80 motherboard with an sWRX8 socket. It is identical to the Threadripper consumer and EPYC data centre types, but features different pin assignments: AMD enabled pins to support more memory channels and PCIe lanes that aren't enabled on the normal consumer Threadripper chips, and they don't use pins that support multiple sockets on EPYC platforms.

The sWRX8 boards also have a chipset, EPYC does not.

Funny you should mention that, I just priced up that very configuration of RAM. Samsung 64GB (x8) 2933MHz came to just under £2400, which is only £4.68 per GB, pretty good price if you ask me. :)

That's the same speed and brand I checked before posting - some pretty good savings to be had at 2133 to 2400mhz - and 8 channel might make up for slightly slower RAM. Will probably wait for some benchmarks to appear on STH I think!

Edit: £2k for 2666mhz if buying new

£1.5k for 2400mhz but 2nd hand

I've got a system design proposal to complete based on these being available at some point before the end of 2020, specified with 512GB/1TB RAM as one of the major requirements. The 128 PCI-E lanes with the fast CPU makes for a killer combination, and is going to allow for a hugely impressive data processing/workstation machine in one. I'm trying to get more info on who is making what boards available, so far I've only got confirmation for ASRock-Rack with samples available in September/October, but importantly they confirmed 7x full 16x PCI-E 4.0 slots, even if they are squeezed together pretty close!

That’s basically the specification I need to put together as well. I assembled a 256GB Threadripper 3970X as an interim simulation machine, but it can’t handle my bigger jobs, I need that 1TB minimum.
 
The 3955WX would have been ideal for me. I don't really need 24 cores but I did need more RAM than the 3950X can handle. Ah well, too late now as my PC is fully built.
