As previously reported, AMD is retaining the same clock speeds on its upcoming Ryzen 9000 X3D chips as the non-X3D versions. These processors are iterations of the existing high-end Ryzen 9000 chips, but with additional L3 cache via 3DV-Cache technology.
The flagship chip of this series will be the Ryzen 99950X3D, which has similar specifications to the non-X3D version, but this time is very different from its predecessor. Normally we'd see some X3D chips with reduced core clocks (mainly base clocks), but the Ryzen 99950X3D retains the 5.7GHz frequency leaked in the CPU-Z screenshots. To be precise, it's 5.65GHz, and, according to the window screenshot, it's an engineering sample codenamed Granite-Ridge, which clearly indicates it's a Ryzen 9000 chip.
Something else to point out in the CPU-Z window is that this processor is rated at a TDP of 170W, which is the same as the Ryzen 9950X. Since the cache size is shown as a 96+32MB configuration, it's obvious that this is an X3D version, and with its 16/32 core/thread configuration, we can confirm that this is indeed the Ryzen 99950X3D. This means that we don’t see any downgrade compared to the 9950X, which also shows that productivity has been improved while upgrading gaming capabilities due to the addition of 64MB of L3 cache.
The chip will have two core composite chips (CCDs) with eight cores each and 32MB of dedicated L3 cache. One of the cores will feature an additional 64MB L3 cache chip below the CCD, bringing the total L3 cache to 128MB and 144MB. Unlike previous generations, placing the L3 cache chipset below the CCD puts the core in direct contact with the IHS, allowing for superior cooling. This maintains the core frequency while unlocking the potential for further overclocking.
AMD Ryzen 99950X3D and Ryzen 99900X3D are expected to be unveiled at CES 2025 at the same time as FSR4 and RDNA4 graphics cards such as Radeon RX9070XT.
