amd threadripper

[SuperCookie78]

since threadripper is just 2 ryzen cpus glued together is it possible they can fit 2 more under the same heatspreader? obviously it would super hot but powerful none the less.

There is already 4 under the heatspreader.

i thought it was 2 8core dies not 4 4core dies

It has 4 8core dies.  AMD only enables two of them.

then why put all 4 on there in the first place

Other two might be dead or doesnt meet there standards

so they could enable them right? or are they just dead dyes that are just there to more evenly distribute pressure from mounting coolers

4 8 core dies, 2 have all broken transistors, but the silicon is still there

The other two are not real chips.  They look like dies if you crack them open but they're most likely taken off the factory line before ever becoming working dies (probably because they found defects that would have prevented them from working), and don't actually include any transistors.  EPYC (the server part these are based on) uses all 4.

Most probably the latter. I think AMD might be able to better use dies that didnt meet their initial standards for other products or other future products. My guess is that those silicon spacers are dies that died.

OMG only 2 of them are working. 2 of the dies are dummys and dont work cant be activated.

They claim that's not what they are (ryzen dies that failed).  However, they also say they're blank, but you can easily crack one open and see what looks like a normal die.  Our leading theory from another thread is that "blank" is an industry term that means something different than what most people would assume, and they are in fact what I described.

silicon that had impurities that would've caused issues later down the line?

That would be a little risky what if you smash open the working one lol. Also delidding it is hard as they are soldered on. It is possible though. Theres like a special method to do it.

something like that.
