  "account": "Details of an unreleased AMD Ryzen 9 5900X3D surfaced on Chinese forum Chiphell, suggesting that the company may have planned to release two SKUs at the time. If true, this would have made the 5900X3D a formidable competitor to the Ryzen 7 5800X3D. The 5900X3D is a 12-core processor, similar to its non-X3D counterpart, but features a larger 128MB L3 Cache, which would have been its key selling point. The 5800X3D, on the other hand, has a 96MB L3 Cache. Both processors boast two CCDs, but only one of them houses the 3D V-Cache technology. The exact base and boost clock speeds for the 5900X3D remain unclear, although a HWInfo screenshot indicates it can reach nearly 4.8GHz, placing it in line with the 5800X3D. Despite being four years old, the 5800X3D remains a top choice for gaming on AMD's AM4 platform, so popular that AMD even released a 10th anniversary edition of the CPU. While AMD launched multiple 3D V-Cache CPUs with the introduction of its AM5 platform and Ryzen 7000 Series processors, including the 7800X3D, 7900X3D, and 7950X3D, the 5900X3D and its overclocking capabilities were notably absent. This situation changed again with the release of the Ryzen 9000 Series, which officially opened up the entire 3D V-Cache lineup to manual overclocking.",
