We can tell that the four chiplet designs are that way by the L3 cache: when only four chiplets are active, it has 128 MB of L3 cache, however with all eight chiplets, the 3990X will have 256 MB of L3 cache. Moving back to Team Red, the 64-core Threadripper is a bit cheaper than the 64-core, single-socket Epyc 7702P—but not enough to write home about. This means that inside it will have eight chiplets, each with 8 cores enabled. Recensione ⭐AMD Epyc 7742. As a result, we do expect the per-core frequency of the 3990X to be higher than the EPYC, but lower than the other Threadrippers.In our testing of the 3970X 32-core hardware, we saw that in the 280W TDP we had around 75W reserved for non-core activities, and 205W for the cores. This brought the top Core i9 part's cost per thread in line with—and even a little cheaper than—the competing Threadripper parts.This is in sharp contrast to Intel's pricing strategies, which have tended for years to run more toward "pick the CPU you can afford" than "pick the CPU that fits your needs." The best example of this strategy is Intel's top-of-the-line Intel Xeon Platinum series, which literally cannot be priced—they're not available in retail—but can be reasonably estimated to cost roughly ten times as much per thread as the closest competing Epyc parts.Ultimately, this means Windows 10 Pro isn't really appropriate for Threadripper 3990x at all—if you're building a 3990x system, you need to plan on a roughly $120 upgrade from Pro to Workstation or on paying the $84/year for a Windows 10 Enterprise subscription. On Friday, AMD launched its latest monster CPU—the 64-core, 128-thread Threadripper 3990x. One thing that will differentiate the 3990X from the EPYC hardware will be memory and PCIe count. If you want Threadripper CPU threads, you're going to pay roughly $30 apiece for them, whether you're looking for the smaller or larger parts.Threadripper and Epyc have more in common than not. Moving up to the 3990X means double the IF connections, but the others stay the same. AMD is announcing today that the 3990X will have 64 cores, 128 threads, and will have the full 256 MB of L3 cache.Ever since AMD announced its latest enterprise platform, Rome, and the EPYC 7002 series, one question that high-end desktop users have been wondering is when the 64-core hardware will filter down into more mainstream markets. Team Blue slashed the price for its flagship HEDT part in half in a single year. However, as we’ve learned from AMD since introducing Ryzen, they like to go aggressive and offer some level of parity between consumer and enterprise hardware.AMD isn’t giving too many details away just yet. The 3990X will likely be AMD's workstation answer to its server-oriented EPYC 7742. Unfortunately we don’t get any more info than that at this time, but if we consider the 24-core 3960X at $1399, the 32-core 3970X at $1999, I can easily see this processor being at least $3999, if not more. AMD Epyc 7702. The 3990x is a great processor, however, there were difficulties and some disappointments during the testing.
