Intel’s Rocket Lake Desktop CPUs, which include the Core i9-11900K, Core i9-11900 and Core i7-11700, were seen on the Chiphell Forums (via Harukaze5719) All three chips are part of the 11th generation family and feature 8 cores with 16 threads. The leak points out that these three chips are initial engineering samples and therefore have much lower clock speeds than the retail variants that will be available around the first quarter of 21.
Intel Core i9-11900K, Core i9-11900, Core i7-11700 8 Core, 11th generation, Rocket Lake Desktop CPUs Spotted
Starting with the specifications, there is not much difference in terms of core configuration, as each CPU contains 8 cores, 16 threads, 16 MB of L3 cache and 4 MB of L2 cache. The difference here is the clock speeds and the TDPs of each respective chip. The Intel Core i9-11900K will be the flagship CPU of the 11th generation family and will have a basic TDP of 125W and a PL2 rating of 250W. The Intel Core i9-11900 and Core i7-11700 are standard non-K SKUs with basic 65W TDPs and 225W PL2 ratings.
The core clocks for these chips are also not final, as the Intel Core i9-11900K is rated with a base frequency of 3.40 GHz and a boost frequency of 4.8 GHz (1 core) and 4.3 GHz (all cores). The Core i9-11900 has a base frequency of 1.80 GHz and increases to 4.5 GHz (1 core) and 4.0 GHz (the whole core). The i7-11700 also has a base clock of 1.80 GHz, but has much lower boost clocks of 4.3 GHz (1 core) and 3.8 GHz (all cores). Again, these are not final clock speeds at all. The Core i9-11900K will come with a base clock of 3.50 GHz and a boost clock of 4.80 GHz (all-core) and 5.30 GHz (single-core TVB 3.0).

A singular performance benchmark for the Core i7-11700 was shown where the chip scored 529 points on the single-core and 4672 points on the multi-core test on the Cinebench R20. A Core i7-10700 for comparison scores 499 points in single-core tests and 4834 points in multi-core tests. So, right off the bat, we can see that the Core i7-11700 isn’t exactly much faster than its predecessor, but we also have to take into account the much lower clock speeds than the Intel Core i7-11700 ES CPU here . offer. The standard Core i7-10700 has a much higher base clock of 2.90 GHz (1.1 GHz higher) and also increases much more 4.80 GHz (1 core) and 4.2 GHz (all core).
The most interesting information that comes out of this leak and also what we hear is that the Intel B560 line in the next generation will support memory overclocking. The leak provided a small glimpse of this, running the memory at 4133 MHz (XMP enabled). On previous generation B-series motherboards, memory overclocking has been disabled and even XMP features have been blocked and exclusive to high-end Z-series motherboards.
The leak also mentions the prices of these ES CPUs which are 2,800 Chinese yen ($ 430) for the Intel Core i9-11900K, 2,300 Chinese yen ($ 350) for the Core i9-11900 and 1,600 Chinese yen ($ 245) for the Core i7-11700 CPU. These are not official retail prices, but they are definitely lower than 10th generation parts in retail.
The Core i9-10900K is officially sold for $ 499 in the U.S., and while the Core i9-11900K is not technically a replacement for the 10-core offering, it appears to be priced at $ 80 lower. Since Intel is lowering the core count and betting everything on its Cypress Cove core architecture, they may have to lower the price per segment to compete with AMD’s Ryzen 9 and Ryzen 7 parts, which not only offer more cores and threads, but also come with superior MT (Multi-Threaded) performance.
