When the AMD Threadripper 1950X was delidded it was assumed that the AMD Threadripper CPU was actually an AMD EPYC CPU as there were 4 dies. It seems that is not the case and that AMD Threadripper is different in the way that two of the dies are not functional and are basically rocks with no path to function.
If you are wondering how you can activate those dies then let me tell you that it is not possible as those dies are not functional at all. I do not know why AMD put them there when there is no use for them in the first place but I am sure there is a logical explanation.
James Prior took to Twitter in order to make things clear. He clearly pointed out that 2 of the 4 dies do not work. The word he used for them was dummy. Here is what he had to say:
Threadripper is not a Epyc processor. Different substrate, different dies. 2 dies work, other 2 have no path to operation. Basically rocks. Those are some expensive pieces of rock, for sure. However, AMD’s choosing of “dummy” instead of inactive seems correct here.
The following diagram should allow you to better understand what is going on:
With the high core count Intel CPUs coming out soon it will be interesting to see what kind of performance they have to offer as compared to these AMD Threadripper CPUs. From what we have seen so far, AMD Threadripper is cheaper and the cores are clocked at higher frequencies as compared to competing Intel CPUs.
It seems that 32 cores AMD Threadripper CPUs will not be something coming out soon after all.
Let us know what you think about AMD Threadripper CPUs and whether or not you are interested in buying one of these processors.
