How far would you go to prove a point? Well, the overclocker and CPU delidding expert der8auer has decided to put AMD's "Dummy Dies" claim to the test, to find out once and for all whether or not AMD is using failed/defective Ryzen dies or silicon spacers.  

This process took a lot of time, money and effort, requiring der8auer to acquire a full Ryzen Threadripper CPU from retail, which is not an insignificant investment. 

Below you can see his results, though we would advise that you watch his video in full to see how he managed to remove these CPU dies from AMD's IHS and substrate. This poor CPU has been completely destroyed, though at least it has given everyone something to talk about. 

The eagle eyed amongst you will be able to see the locations of the CPU cores in these Ryzen dies, though I imagine that some of you will point out that two of these dies look different than the others. This is likely indicative of different levels of sanding during der8auer's process, though it still showcases that none of this silicon is blank.

This raised many questions, like whether or not 24 and 32 core Threadripper CPUs would be manufactured in the future with four active CPU dies, though to say the least the release of such a processor would be problematic.

First of all, such a part would likely consume too much power to be usable on existing X399 motherboards, at least without substantially lower clock speed than other Threadripper series CPUs. 

Looking at AMD's EPYC 7601, we see a TDP of 180W and base/boost clock speeds of 2.2/3.2GHz, clock speeds that are exceptionally low for a consumer product. A Threadripper series CPU with these clock speeds would seem crippled in terms of single-threaded performance, which is a huge deal for the consumer market. 

This is not to say that a 24-core or a 32-core Threadripper CPU is impossible, just that it presents AMD with some interesting challenges. Beyond that AMD's Threadripper series of products is not exactly designed to be a high volume lineup, so demand for a larger Threadripper series CPU would be extremely limited.

His research doesn't mean much. He can't get the equipment to figure out if they worked or not anyway. It's all just speculation. Could just be failed Epyc cores and they Lazer them out completely which is why you can't BIOS hack and add more. Because they are dummies. Like AMD said. They don't work.Quote

Ok, I must be missing something. Why would he rip apart the top of the line TR looking for blank dies? Aren't the blanks only used on lower end models? Isn't the 1950x the top part, with all dies intact? What key piece of info am I missing here?Quote

No the 1950x is obviously not the top end part because there are a further 16 cores and 32 threads on the die that have been disabled, or are faulty.

Seriously, expect a 32/64 TR at some point after Intel finally launch all of theirs.

I think they are there by design dude I really do. Yeah they may be there to stabilise the IHS but the design is obviously to have four. Oh, and the IF must work on them too, or they wouldn't be there, IMO*

*note, most of that is just me speculating to form an opinion....Quote

So do they have terrible yields so the have lots of bad dies to place in there or do they have extremely low costs, so they can afford to disable good dies?Quote

It's not a yield problem. I've not seen Ryzen go out of stock once yet !Quote
