I’m not a big one on posting first-party benchmark results, but the high-level overview from Intel was this:

At 3.3 GHz, 12900K is +19% better in Single Thread Performance over the 11900K
Over the 11900K, the 12900K is +19% better at 1080p High with RTX 3090
Over the 11900K, the 12900K gets +84% better fps when concurrently streaming
Over the 11900K, the 12900K is +22-100% better in content creation (Adobe)
Over the 11900K, the 12900K is +50% faster in BlenderMT at 241W (vs 250W)
Over the 11900K, the 12900K performs the same in BlenderMT at only 65W (vs 250W)
