AMD Ryzen 9 9950X3D Leaks on CPU-Z with 5.6+GHz Boost Clock and 128MB L3 Cache

The recent leak has confirmed that the AMD Ryzen 9 9950X3D will maintain its clock speeds, delivering the same boost performance as its non-X3D counterpart.

Insights into the AMD Ryzen 9 9950X3D: An Engineering Sample Unveiled in CPU-Z

Recently, reports have surfaced indicating that AMD is set to uphold the clock speeds found in the non-X3D variants of its Ryzen 9 9000 series processors. The Ryzen 9 9950X3D is an evolution of the high-performance Ryzen 9 9000 chips, featuring enhanced L3 cache capacity made possible by the innovative 3D V-Cache technology.

Positioned as the flagship processor, the Ryzen 9 9950X3D promises impressive specifications akin to the non-X3D edition. However, it diverges from previous models by not exhibiting the typical clock speed reductions often seen in other X3D processors. Specifically, the leak indicates a maintained boost clock of 5.7 GHz, as evidenced in a screenshot from CPU-Z. More precisely, the clock achieves 5.65 GHz. This engineering sample is dubbed Granite-Ridge, confirming its identity as a member of the Ryzen 9000 family (source: @94G8LA).

Analysis of the CPU-Z window also shows that the Ryzen 9 9950X3D will carry the same 170W TDP rating as its predecessor, the Ryzen 9950X. The processor’s architecture reveals a 96 + 32 MB cache configuration, underscoring its designation as an X3D model. Coupled with a robust 16-core/32-thread setup, this affirms the Ryzen 9 9950X3D’s stature, highlighting its capacity to match the productivity capabilities of the 9950X while simultaneously enhancing gaming performance through an additional 64 MB of L3 cache.

The architecture includes two Core Complex Dies (CCDs), each housing eight cores paired with 32 MB of dedicated L3 cache. Notably, one CCD will incorporate an additional 64 MB L3 cache chiplet situated beneath it, resulting in a total of 128 MB of L3 cache, augmented by 144 MB when including L2. This innovative placement of the L3 cache chiplet beneath the CCD enables direct contact with the Integrated Heat Spreader (IHS), facilitating superior cooling. As a result, this design allows the preservation of core clocks while unlocking potential for further overclocking opportunities.

Both the AMD Ryzen 9 9950X3D and Ryzen 9 9900X3D are anticipated to make their debut at CES 2025, where they will likely be showcased alongside new advancements in graphics cards, including the upcoming FSR 4 and RDNA 4-based Radeon RX 9070 XT.
