The latest benchmarks from Intel’s Core i9-11900K Rocket Lake flagship CPU have been leaked at Geekbench. The figures show a record performance for the upcoming chip that will feature a brand new core architecture on an Intel Desktop platform for the first time in more than 6 years.
Intel Core i9-11900K Rocket Lake Desktop CPU reduces all its competitors in performance with a single thread, 13% faster than AMD Ryzen 9 5950X
The Intel Core i9-11900K with its multiple Cypress Cove core offers the largest CPU architectural upgrade in over 6 years. This is because since the 6th generation Skylake CPUs, all the Intel CPUs up to the 10th Generation Comet Lake CPUs have used the same identical disk architecture, based on the 14nm process node.
Intel Core i9-11900K Rocket Lake Desktop CPU Specifications:
The Intel Core i9-11900K will be the flagship 11th Gen Rocket Lake Desktop CPU. The chip contains 8 cores and 16 wires. This will result in 16 MB L3 cache (2 MB per core) and 4 MB L2 cache (512 KB per core). In terms of clocks, the CPU operates at base frequencies of 3.5 GHz, but in terms of boost, the CPU will have a maximum gain clock of 5.2 GHz (1 core), while maintaining the overall boost frequency at 4.8 GHz.
The chip also contains Thermal Velocity Boost which should deliver a 100 MHz jump in the maximum clock frequency. This should result in a 5.3 GHz single-core gain clock, making it the first CPU to ever hit such a high frequency outside the box. However, keep in mind that the Core i9-11900K, regardless of the use of the Cypress Cove cores, has lower cores and wires than the Intel Core i9-10900K. This is partly due to the back port of Cypress Cove on the refined 14nm process knot. It is said that the CPU has a power limit on the first phase of 125W, which is standard for a flagship Intel SKU and the second phase power limit or PL2 is 250W.

To meet the standard, the CPU has been tested at least three times on the same configuration consisting of a Gigabyte Z490 AORUS Master motherboard and 32 GB DDR4-3600 MHz memory. During the tests, a maximum single-wire score of 1905 points and a multi-wire score of 10994 points were seen. This sets the Intel Core i9-11900K Rocket Lake CPU as the fastest disk drive ever created. Compared to AMD’s fastest Zen 3 chip, the Ryzen 9 5950X, the Intel processor is 13% faster.
At the same time, it loses in multi-threaded tests due to a maximum of 8 cores and 16 wires, while AMD’s Ryzen 5000 family scales to 16 cores and 32 wires, which is twice as much as the Intel Rocket Lake flagship. The Intel Core i9-10900K averages 1402 points in single-core and 10924 points in multi-core tests. Despite having more cores and wires, the 11900K beats its predecessor with a slight performance advantage that is very impressive.
However, we must remember that this is an excessive result. The Core i9-11900K can work on stock at 5.3 GHz, but it is only valid for a single core. The slide here can be seen with an overall boost of 5.3 GHz, which is 500 MHz higher than the standard overall boost of 4.8 GHz. The share multi-core score would therefore be lower, but even then not by a large margin. But with that said, we’ve found that the Rocket Lake processor is very difficult to cool down with the AIDA64 FPU stress test that pushes it up to 98C, even when using a 360mm AIO liquid cooler.
While this is a beautiful showcase for Intel, please note that the Rocket Lake processors will not be in retail until the end of March 2021. This will bring them close to AMD’s next answer, which should be either in the form of an ‘improved Zen 3+ Warhol’ or a next generation Ryzen series on Zen 4. Intel is also planning to launch its 12th generation ‘Alder Lake’ Desktop CPU range available by 2H 2021 or Q3 2021, which means Rocket Lake CPUs will be replaced within 1 or 2 quarters, giving them an even shorter lifespan than Kaby Lake, which was also replaced by Coffee Lake CPUs a few quarters later.
