TSMC’s lack of manufacturing capacity is why AMD decided to release only one Ryzen processor with 3D V-Cache expansion technology – the Ryzen 7 5800X3D. The portal provides information about this. DigiTimes…
During CES 2022, AMD introduced the Ryzen 7 5800X3D processor with increased cache memory due to the 3D-V-Cache technology. Even before the announcement, it was assumed that AMD would also present Ryzen 9 5900X and Ryzen 9 5950X models with the same technology, as it had previously demonstrated a prototype Ryzen 9 5900X with 3D V-Cache. However, the Ryzen 7 5800X3D turned out to be the first and so far only processor of the Ryzen series with an increased cache.
Recalling their sources DigiTimes reports that TSMC’s 3D SoIC packaging technology (the basis for 3D V-Cache) for combo platforms has not yet reached the level of mass production. Production capacities are only available to the subcontractor to a limited extent, and these, too, are mainly geared towards the needs of the corporate sector. As a reminder, AMD has already introduced Milan-X server processors that are equipped with 3D V-Cache technology. TSMC is currently finalizing the construction of a new factory in Chunan, Taiwan, which will use the new technology for 3D processor packaging. She should earn this year. However, the manufacturer may not have time to start mass production of the Ryzen 7 5800X3D before the new AMD chips appear on the Zen 4 architecture.
Note that 3D V-Cache improves game performance significantly. Adding an additional cache die in the processor allows latency-sensitive gaming applications less access to the main DRAM stack and instead takes resources directly from the 3D V-cache. This can increase gaming performance by up to 15%, which was shown when the non-flagship 8-core AMD processor was faster than the 16-core Intel Core i9-12900K.
The Ryzen 7 5800X3D will be released this spring. AMD has several months to build up reserves. If the capacity shortage at TSMC continues until mid-2022 or later, there is a risk that the Ryzen 7 5800X3D will remain a niche product, as the company will be releasing processors based on the new Zen 4 architecture by the end of the year.
