VideoCardz rumor, but it looks realistic:
AMD Ryzen 9 3950X: 16 cores at 105W TDP
According to a slide we received today, AMD will launch Ryzen 9 3950X as world’s first 16-core mainstream processor. The slide basically “confirms” the speculation which began at Ryzen 3000 announcement at Computex.
AMD Ryzen 9 3950X would utilize all available cores from both dies. It would preserve the TDP from Ryzen 9 3900X which features 12 cores but at the cost of a lower base clock. This AM4 processor is supposedly a 105W TDP part.
The 3950X features a boost clock of 4.7 GHz, the highest from all Ryzen 3000 CPUs. The pricing and availability date have not yet been confirmed.
The authenticity of the slide could not be confirmed in such a short time, but we decided to publish it regardless. Take it with a grain of salt
