[PConline News] This year, AMD has been on a multi-core spree, launching the 8-core, 16-thread Ryzen processor for desktop users and also introducing the top-tier 16-core, 32-thread Ryzen Threadripper for the server market, as well as the EPYC processor with 32 cores and 64 threads. Recently, some details about the Threadripper processor have surfaced, but there's no sign of any accidental four Ryzen 7 modules. Instead, AMD officially enabled only 16 cores, leading many to wonder whether AMD intentionally left some cores disabled. Could a 16-core Threadripper be turned into a 32-core, 64-thread EPYC processor if the right method is found? In response, AMD officials have made it clear: Threadripper cannot be unlocked, so don't get your hopes up.
Previously, we knew that AMD used a "glue package" design for the EPYC processor. The 32-core chip actually consists of four Ryzen 8-core, 16-thread processors, similar to the desktop-class Ryzen Threadripper. Recent leaks have confirmed this. Considering AMD's past history of enabling more cores in certain models, some people speculated whether Threadripper could be unlocked to reach 32 cores. However, AMD employee James Prior recently denied this on Twitter, stating that Threadripper and EPYC are built on different architectures with different core configurations. According to him, only two cores can work properly, and the other two are not functional at all.
From this perspective, AMD seems to have anticipated the possibility of unlocking cores in Threadripper and has already taken steps to prevent it. However, there's still a chance that the current 16-core Threadripper might actually be an EPYC processor with some cores disabled. If that’s the case, then those extra cores would remain inactive, aligning with AMD's explanation that unlocking isn’t possible.
In conclusion, AMD has clearly stated that Threadripper cannot be upgraded to a 32-core EPYC processor. So, don’t expect such a miracle to happen. While it’s tempting to think that there might be hidden potential, the reality is that AMD has designed these chips with specific purposes in mind, and they’re not meant to be modified by end-users. For now, it looks like Threadripper will stay as a high-end workstation CPU, while EPYC continues to dominate the server space.
