Ryzen 7 5800X3D is gonna be hard to get due to complex production stacked cache

The AMD Ryzen 7 5800X3D will be the only consumer-level processor to include an additional stacked 3D V-Cache that sit above the compute dies. And that's difficult and costly, the processor might end up being a limited edition.

According to Digitimes sources, TSMC's 3D SoIC technology is not yet in volume production, and limited capacity is available being allocated to enterprise chips. The Taiwan Semiconductor Manufacturing Company (TSMC) is building a new sophisticated packaging plant in Chunan, Taiwan, which is slated to be operational later this year, although it may not be ready in time for volume 5800X3D production prior to the release of Zen 4 later this year. AMD believes that the presence of all of that more L3 cache will result in a significant boost in gaming performance over the standard 5800X, which isn't exactly a slouch in the first place. But with the recent Alder Lake release, it might be enough to grab back the #1 position. The notion is that latency-sensitive applications such as games will benefit from not having to access the DRAM as frequently as they would otherwise have to. Although AMD claims that the technology can provide a 15 percent boost in performance, which is enough to put it ahead of the 12900K, we'll reserve final judgment until we've had a chance to test the 5800X3D for ourselves once we review it.

The Ryzen 7 5800X3D is scheduled to go on sale in spring 2022, so you'll have to wait a few months longer. If TSMC's limited manufacturing capacity remains until the middle of 2022 or beyond, it is possible that the 5800X3D will continue to be a niche processor. It is expected to be replaced by Zen 4 CPUs in the second half of 2022.
