Intel may not offer the insane multi-threaded performance that AMD’s Ryzen 5000 CPUs offer, but they’re returning with vengeance in the single-wire segment with the leaked benchmarks of the 8 Core Rocket Lake Core i9-11900K offering a massive performance improvement which would be enough to regain their fastest game CPU throne.
Intel’s Core i9-11900K 8 Core Flagship CPU benchmark leaks out, Rocket Lake faster than AMD’s Zen 3 ‘Ryzen 5000’ in single core performance
The Intel Core i9-11900K is the flagship of the 11th Gen Rocket Lake Desktop CPU family. It is the first family after Skylake to use a brand new core architecture while still using the 14nm process node. The new Cypress Cove architecture is said to deliver double-digit returns in IPC, which should be enough to put Intel back in the single-core performance throne, as AMD and the Zen 3 series completely destroy Intel’s Comet Lake processors in that division has.
Intel Core i9-11900K 8 Core and 16 thread 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). As for the gain clocks, we have already seen that the CPU operates at base frequencies of 3.5 GHz, but as far as the gain is concerned, the CPU will have a maximum gain clock of 5.2 GHz (1 core) while maintaining the overall boost frequency. becomes 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. Keep in mind, however, that regardless of using the Cypress Cove cores, the Core i9-11900K 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 node.

The CPU is said to have a 1st phase power limit of 125W, which is standard for a flagship Intel SKU, and the second phase’s power limit or PL2 is rated at 250W. This means that when the maximum advertised clock speed is reached, the processor can indeed extract the said amount of watts from the PSU, and it is one of the most powerful 8-core chips ever produced. This may also explain why Intel did not set up 10 cores and 20 wires on its 11th generation, as it would be a powerful sample of a chip that would break even beyond the 250W power limit.

Intel Core i9-11900K 8 Core & 16 thread Rocket Lake Desktop CPU Criteria
Marked by HXL, Bilibili posted a screenshot of the CPU-z benchmark with the Intel Core i9-11900K. The CPU reportedly scored 695.4 points in single-wire and 6522.1 points in multi-wire tests. The multi-thread count puts the Core i9-11900K at 15% faster than the Core i7-10700K and is equal to the Ryzen 7 5800X.
It all turns into single core tests, as the Core i9-11900K finishes 25% faster than the Intel Core i7-10700K, 19% faster than the Core i9-10900K, and also 5-7% faster than the Ryzen 7 5800X & the Ryzen 9 5950X. The following is a table with the performance comparisons between the CPUs:
If these results are near the right thing, Intel will definitely have a powerful chip for gamers in 2021. That is, AMD will not offer its own refresh or new Zen series later in the coming year. But we have to take into account the higher power consumption and also the power inputs that will be a direct result of the 14nm architecture. In the efficiency department, AMD will still have a big advantage over Intel and it is not expected to be disrupted anytime soon or at least until Intel launches its own 10nm SF-CPUs (Alder Lake-S) planned for 2H . 2021
Intel Core i9-11900K, Core i9-11900 and Core i7-11700 ES Rocket Lake CPU Criteria
In addition to the leaked CPU-z result, Chiphell forums also posted full tests of various Intel Rocket Lake ES CPUs including the Core i9-11900K, Core i9-11900 and the Core i7-11700. Note that these chips are not final variants and have lower clock speeds.
For example, the i9-11900K runs at 3.4 GHz base and 4.8 GHz boost, the Core i9-11900 runs at 1.8 GHz base and 4.5 GHz boost while the Core i7-11700 runs at 1.8 GHz base and 4.4 GHz boost. These are similar tests to the ones we saw a few days ago, so without further ado, the criteria are as follows:

As we reported, the Intel Rocket Lake CPUs will be shipped months after the 500 Series boards available on January 11th. The CPUs are expected to be announced at CES 2021, but a hard launch is only planned in March-April.
