AMD is likely to publicly unveil their Zen 4-based Ryzen 7000-series CPUs with 3D V-Cache at CES 2023, however, this has not yet been confirmed.
According to a South Korean media report, the company is planning to launch three new Ryzen 7000 X3D processors in January with 96 MB or 192 MB L3 cache. As per Quasarzone, a popular South Korean publication (the report was kindly translated for the world by @harukaze5719), the three Ryzen 7000 X3D models will have 16, 12, and eight cores. Because the CPUs are slated to be launched in January, AMD will most likely announce them during CES in order to draw as much attention to the new components and their capabilities as possible.
3D V-Cache is best suited for tasks that require high memory bandwidth and single-thread performance. For most client PCs, this implies gaming. Indeed, even after AMD released its most recent products, the Ryzen 7 5800X3D remains one of the finest CPUs for gaming.
Furthermore, the Ryzen 7000 X3D parts are expected to benefit even more from 3D V-Cache due to potentially higher bandwidth, further strengthening their performance in the aforementioned workloads and applications.
AMD’s decision to launch three Ryzen 7000X3D models with 3D V-Cache, increasing the number of X3D CPUs for client PCs from one (in the case of the Ryzen 5000 family) to three (for the Ryzen 7000 series), is an intriguing move. On the one hand, increasing the family of 3D V-Cache-enabled desktop CPUs would boost AMD’s gaming offerings and presumably democratise price, making it simpler for AMD to compete with Intel.
On the other hand, they will compete with processors lacking 3D V-Cache and will eat into sales of components with greater core counts.
