The leak comes from chi11eddog over on Twitter, and these Zen 3 SKUs with 3D V-cache could pack a decent punch and be priced to kill, especially since we are talking about an 8-core/16-thread and 6-core/12-thread SKUs that pack 100MB and 99MB of total cache.

In terms of numbers, the Ryzen 7 5700X3D is an 8-core/16-thread SKU with 100MB of total cache or 512KB of L2 per core and 96MB of shared L3 cache. The Ryzen 7 5700X3D ends up with a slightly lower clock compared to the Ryzen 7 5800X3D, ticking at a 3.0GHz base clock. The Ryzen 5 5500X3D is a 6-core/12-thread SKU with 99MB of total cache, as it has two fewer cores. It also works at a 3.0GHz base clock, which is lower than 3.3GHz for the Ryzen 5 5600X3D. The two new SKUs could also end up with a lower TDP as well.

Unfortunately, there is no word on when we can expect these chips or whether these will be available globally or regional and/or retailer exclusives.

New AM4 Ryzen 7 5700X3D and Ryzen 5 5500X3D are coming ? 🧐🧐🧐
5700X3D: 8C/16T, 4.1GHz/3.0GHz, 96MB L3 cache,
5500X3D: 6C/12T, 4.0GHz/3.0GHz, 96MB L3 cache.
