AMD Ryzen 9 9950X3D
2025 high-end processor manufactured by AMD
The AMD Ryzen 9 9950X3D is a flagship desktop microprocessor designed by AMD. It was announced in January 2025 at CES and released on 12 March 2025 as part of the Ryzen 9000 series. The processor targets both gaming and content creation workloads and features AMD's second-generation 3D V-Cache technology.
A higher-end variant, the AMD Ryzen 9 9950X3D2, was announced at CES 2026. It was released on April 22, 2026.
Overview
The Ryzen 9 9950X3D is based on the Zen 5 "Granite Ridge" architecture. It incorporates 16 cores and 32 threads, with a base clock frequency of approximately 4.3 GHz and boost speeds reaching up to 5.7 GHz.
One of its two core complex dies (CCDs) includes AMD's stacked 3D V-Cache, resulting in a total of around 128 MB of L3 cache and for a total of 145 MB of CPU cache. The processor has a default thermal design power (TDP) of 170 W, with a maximum consumption of 230 W. It is compatible with the AM5 socket platform, supporting DDR5 memory up to 256 GB in size.
Design and innovations
The 9950X3D introduces AMD's second-generation 3D V-Cache implementation, which repositions the cache die to below one of the core complex dies (CCD) to improve thermal characteristics compared with earlier models. This design allows higher sustained boost clocks under load.
The public source identifies “AMD Ryzen 9 9950X3D” as 2025 high-end processor manufactured by AMD. This brief keeps that definition visible, then builds a research path around Ryzen, 9950X3D and high-end.
Why this record matters
A short description can identify a subject without explaining its stakes. For “AMD Ryzen 9 9950X3D”, the useful work is to connect “2025 high-end processor manufactured by AMD” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated May 31, 2026. The linked authority identifier is Q134166256. 1 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2025 and 2026.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
