The 3990 X will likely be AMD’s workstation answer to its server-oriented EPYC 7742. As such, it’ll have eight chiplets with eight cores each, while the 24 – and 32 – core 3960 X and 3970 X CPUs we saw earlier have four chiplets with four and six cores, respectively.
We still don’t know if the 3990 X will have eight-channel memory with 128 PCIe 4.0 lanes like the EPYC or quad-channel memory and 64 PCIe 4.0 lanes like the (X /) X. Also, AMD hasn’t said whether it’ll run on the same “Socket sTRX4” platform as those two chips, or if it will use the EPYC SP3 socket, or even an all-new platform. Based on anearlier MSI leak, the likely scenario is 64 PCIe 4.0 lanes running on the same sTRX4 platform as the (X and 3970 X.
AMD’s review embargo for the latter chips lifted yesterday, and based onwhat we’re seeing, the 3990 X is likely to be a monster workstation performer. All of the Threadripper chips are designed not for gaming, but video editing, 3D animation and other content creation chores. In that area, AMD is crushing Intel, besting the i9 – 10980 XE and i9 – 9980 XE in most benchmarks while consuming less power.
Intel should be worried, as it’s seeing AMD crashing into key areas like servers and workstations. It still dominates areas like gaming (although AMD’s latest regularRyzen chipsseriously closed the gap there this year), while AMD is still struggling with overclocking, According to the latestreviews. However, Intel will need to overcomeyield problemswith both 14 – and 10 – nanometer parts or AMD will start eating its lunch there, too.
