AMD's Ryzen 9 9950X3D & 9900X3D 3D V-Cache CPUs won't be getting nerfed in their clock speeds and will deliver similar synthetic performance as the Ryzen 9950X.
AMD Ryzen 9 9950X3D & 9900X3D CPUs deliver equivalent single and multi-threaded performance as the non-X3D chip, feature same clocks
AMD's upcoming 3D V-Cache "X3D" CPUs are seemingly too powerful compared to their predecessors. Not only did we witness the excellent synthetic and gaming performance of the 9800X3D, but apparently, the upcoming higher-end SKUs will deliver even better synthetic performance while increasing the gaming capability significantly.
The AMD Ryzen 9 9950X is soon getting an X3D version and so will the Ryzen 9 9900X. If you are aware of the X3D "3D V-Cache" chip design, you would know that typically these processors bring lower base clocks than the regular designs, but the 9000X3D is different since the SRAM die is situated below the CCD rather than on top. This allows proper cooling, which resulted in a higher base clock speed for the Ryzen 7 9800X3D.
However, the AMD Ryzen 9800X3D still has a 300 MHz boost clock lower than the Ryzen 9700X even though the latter isn't exactly its non-X3D counterpart.
As per the information provided by the leaker HXL (@9550pro), the Ryzen 9 9950X3D apparently won't get any cut in the core clocks, which means the same base and boost clock as the Ryzen 9 9950X. This means, 4.3 to 5.7 GHz out of the box, which would offer excellent performance in apps and games.
As per the leaker, the AMD Ryzen 9 9950X CPU would deliver equivalent single and multi-threaded performance to the non-X3D chip in Cinebench R23. Apart from similar productivity performance, the X3D chip should offer a strong gaming performance uplift over the 9950X.
This wasn't the case with some of the previous chips, as the X3D chips lagged behind their non-X3D editions noticeably in productivity due to compromised clocks and limited overclocking capability.
Apart from the performance, it's reported that there won't be a 3D cache on both CCDs, but it will be similar to its predecessors, i.e., a 3D V-cache only on a single CCD. AMD Ryzen 9 9950X3D will feature an additional 64 MB of L3 cache apart from the 64 MB L3 cache that is available on the chip (32 MB + 32 MB). It will be a 16-core/32-thread flagship processor and should bring identical specifications to the Ryzen 9 9950X.
The second 9000X3D chip will be the Ryzen 9 9900X3D, which will be a 12-core/24-thread processor, expected to launch alongside the Ryzen 9 9950X3D at CES 2025. Apart from these processors, we will see the FSR 4 technology and Radeon RX 9070 XT launch at the same event.
