Not content to rest on its CPU laurels (and at the moment, it has plenty of them underpinning it to support its weight), AMD today divulged a few details about an upcoming flagship Ryzen Threadripper CPU, the Ryzen Threadripper 3990X, a high-end desktop mega-processor with a whopping 64 computing cores.
The chip, whose 64 cores can handle up to 128 concurrent processing threads, features a total cache amount of 288MB (256MB of that being L3 cache), and it will have the same 280-watt thermal design power (TDP) rating as the $1,399 Ryzen Threadripper 3960X (24-core) and $1,999 Threadripper 3970X (32-core) processors, which were launched today. (Hit the links for our deep-dive reviews on those two chips, one of which wins our Editors’ Choice award.)
This also thoroughly outstrips Intel’s top chip in its Core X-Series, the 18-core Core i9-10980XE Extreme Edition, which also launched today.
The Threadripper 3990X will be marketed primarily toward the kinds of power users who can actually make use of all the cores and threads their tasks can get their hands on. Think professional content creators, pro esports streamers, AI developers, and the like, who can also make use of Threadripper’s high memory ceiling, lofty PCI Express lane counts, and support for PCI Express 4.0 bandwidth for high-speed storage.
Details apart from the core/thread count, cache, and TDP are scarce. We don’t know anything about the price yet, but considering that the 32-core/64-thread Ryzen Threadripper 3970X already sells for $1,999, it wouldn’t be a stretch to assume the 3990X will retail somewhere in the range of $3,500 to $4,000, if not slightly more.
The 3990X should be compatible with the line of AMD TRX40-chipset motherboards that are rolling out today alongside the other CPUs in the third-generation Threadripper line. (See our first look at all 12 of the TRX40 boards on the market so far.) As a result, anyone looking to jump into the 64-core pool will have to don a new motherboard, as well. With the models launched today, that will be a minimum investment of $400 to $500 additional.
We haven’t heard a rough launch date apart from this AMD statement: “One chip to rule them all in 2020.” If it’s anything like the Threadripper 3970X, however, we can expect huge performance, and that on top of what is already one of the most exciting high-end desktop (HEDT) CPU lineup refreshes that the HEDT market has seen in years, if not ever.
