Details of an unreleased AMD Ryzen 9 5900X3D recently appeared on the internet, indicating that the red chipmaker may have initially planned on releasing two SKUs at the time. If it did, it would have most certainly given the Ryzen 7 5800X3D a real run for its money.
Evidence of the 5900X3D appeared on the Chinese forums, Chiphell. Like its non-X3D counterpart, the 5900X3D is a 12-core processor, but what would’ve set it apart was the larger 128MB L3 Cache. As a quick primer, the 5800X3D has a 96MB L3 Cache.
It also has two CCDs, but only one of them is equipped with 3D V-Cache. So basically, it’s a 96MB+32MB configuration. There is no exact detail to its base and boost clock but the HWInfo screenshot shows the CPU hitting nearly 4.8GHz, more or less putting it on par with the 5800X3D.
Despite it already being four years old, the 5800X3D remains one of AMD’s best gaming CPU for its AM4 platform. It is so popular that AMD actually revived its with a 10th anniversary edition of the CPU. Yes, we know, the age doesn’t add up but the 10th anniversary is in reference to the age of the AM4 platform, which first launched in 2017, along with the very first Ryzen processors.
AMD released more than one 3D V-Cache CPU with the launch of its AM5 platform and corresponding Ryzen 7000 Series processor. This included the 7800X3D, 7900X3D, and 7950X3D. Sadly, and much like the 5800X3D, you couldn’t overclock them.
That last bit changed again with the arrival of the current Ryzen 9000 Series, and officially opened up the entire 3D V-Cache lineup to manual overclocking.
