AMD's James Prior weighs in on the Threadripper "Dummy Dies" controversy

[WYP]

Two of the dies have "no path to operation" and are said to be "basically rocks".

Well hey it cuts down on waste I guess

From what I heard 32 cores isn't going to happen supposedly it isn't possible but the die setup is logical

We will see. They are going to have to release 32 core Epycs if they want to compete in the server/wstn markets with Intel.

I think they already have a 32 core EPYC don't they?

Do they? then there is the answer

 

[Dark NighT]

EPYC was released before Threadripper.

A screenshot from our wholesaler, I think we've been able to order those since august.

Epyc has been on the market for quite some time now. Since mid-June.

Three grand in UKP.

DAYUM.

It is a server CPU with 8 memory channels, 32 cores, 64 threads and 128 PCIe 3.0 lanes. Not exactly low spec.

So why include the 2 extra dies in TR socket design at all? Why not reduce the cpu package size by ~30-40% in the first place?

EDIT: NVM realised it was a stupid question, didn't know TR and EPYC shared a common socket

No this is true, and I bet the equivalent Xeon costs double that much.

Future Expansion

I'm pretty sure the layout was to keep future expansion possibilities while keeping the same socket size. If the market won't buy it, no loss, don't expand. If it looks like Threadripper could take on server processors, ramp it up. By then everyone will be use to the larger rectangular socket and there will be cooling solutions on the market already.

 

[NeverBackDown]

See I told y'all.

 

[Gothmoth]

really, who cares if pure sillicon or not connected deactivated die?

when AMD is not lying and they are not connected it makes barely a difference.
complete dummy dies or defectiv dies. why should i care?

the internet discussion and the outright fanboy war about it is just stupid.

Well... you only need to go to Intel Ark to find out.

You can buy EPYC chips ranging from 8 cores to 32 cores. (minus SMT in those numbers).
however they all have ECC, 128 lanes, and 8 channel RAM.

Whoah ho ho hang on wait, that says $13,000. Thirteen thousand dollars? *faints*

 

[Excalabur50]

I knew about the 32 core epyc but I'm sure someone at AMD said you can't get a 32 core threadripper
