Why does AMD release Ryzen 7 5800X3D only?

At CES 2022, AMD launched a Zen 3 architecture desktop processor with 3D V-Cache technology, bringing an additional 64MB of 7nm SRAM cache to each CCD, making the processor’s L3 cache capacity from 32MB increased to 96MB. However, unlike past rumors, AMD only has the Ryzen 7 5800X3D in the consumer market, and there is no Ryzen 9 5900X3D or Ryzen 9 5950X3D with 3D V-Cache technology.

It was previously widely believed that the Zen 3 processor with 3D V-Cache technology was one of the few means for AMD to compete with Intel’s 12th-generation Core processors in the first half of 2022, obviously, only the Ryzen 7 5800X3D product can’t be resisted. Perhaps manufacturing Ryzen 5000 series processors with 3D V-Cache technology and 7nm process is much more difficult than originally expected.

TSMC has very rich experience and expertise in advanced process manufacturing, and its 7nm process node has a very high yield rate, so the addition of 3D V-Cache technology is likely to be the main factor affecting manufacturing. According to DigiTimes, TSMC’s 3D SoIC technology is still in its infancy and has not yet achieved mass production in the true sense. AMD also released an EPYC processor codenamed Milan-X earlier with 3D V-Cache technology. Considering that these server processors require more CCDs, regardless of market demand or profit, AMD will also give priority to the server product line in the case of limited production capacity. The Ryzen 7 5800X3D is more of a symbolic product, and perhaps the actual supply will be limited.
