Intel's Core i9-11900 which is an upcoming 8 Core Rocket Lake Desktop CPU has leaked out by HXL. The processor is a very early engineering sample that has been tested on the Intel 400-series board platform which more or less confirms that 11th Gen CPUs will be backward compatible on existing LGA 1200 socket motherboards.
Intel Rocket Lake Core i9-11900 8 Core Desktop CPU Tested on Z490 Platform, Leaked Benchmarks Show Early ES Chip With 4.4 GHz Boost Clock, Single-Threaded Performance On Par With Intel's 5.3 GHz Core i9-10900K
The Intel Core i9-11900 is one of the many Rocket Lake Desktop CPUs that will be featured in the 11th Gen lineup. We actually had a post on all of the models which you can read here. As for this particular chip, the Core i9-11900 is the lower TDP variation of the Core i9-11900K. It features 8 cores, 16 threads and will feature clock speeds rated at 1.8 GHz base, 4.4 GHz boost (1-core), and 3.8 GHz (all-core boost).

The main difference between the Core i9-11900K and the Core i9-11900 will be the clock speeds which are a result of the lower TDP. The Intel Core i9-11900K will rock the full 125W (PL1) TDP & Intel's Core i9-11900 will rock a more reasonable 65W (PL1) TDP. The Core i9-11900 will end up around 120-125W when it boosts to its max frequency while the Core i9-11900K will feature max TDP figures of up to 250W.
