AMD Ryzen 7 5800X3D Featuring 3D Stacked L3 of up to 64MB (96MB Overall) to Launch in Late March

AMD’s first consumer Zen 3D SKU has been shipped and should be available for purchase by the end of March. This info was shared by none other than Greymon55, the primary leaker of future AMD/NVIDIA hardware. The Ryzen 7 5800X3D is an octa-core processor featuring a whopping 96MB of L3 cache. It expected to be announced officially in the coming months, with a targeted launch in late March or early April.


The source got this info from the packaging factory which means the processor has been volume produced and should hit retail soon. Sampling and reviews should also begin in the coming weeks. In addition to the 32MB of L3 cache paired with the Core Complex on the CCD, the Ryzen 7 5800X3D will consist of an additional 64MB cache die stacked atop the compute chiplet. This brings up the overall L3 cache size to 96MB. As already demonstrated with the 3rd and 4th Gen Ryzen processors, the last-level cache has a substantial impact on gaming performance. AMD’s own testing shows a boost of roughly 15% with the 64MB cache die.

One drawback of 3D stacking is that it adversely affects the thermals of the CCD, prompting a drop in the boost clocks. The Ryzen 7 5800X3D pulls down the 4.7GHz peak frequency of its predecessor to 4.5GHz. Regardless, it still manages to exhibit a generational uplift in gaming performance which may make the Ryzen 7000 “Zen 4” processors seem less impressive.
