Intel’s Rocket Lake Desktop processors that include the Core i9-11900, Core i7-11700 and Core i7-11700K have leaked again on Bilibili (via Harukaze5719). 11th generation chips are still ES devices, but have much higher clock speeds since they are in the second ES2 variant compared to the ES1 variants we saw earlier.
Intel Core i9-11900, Core i7-11700 7 Core i7-11700K 8 Core Rocket Lake Desktop CPUs Leaking Out Again
All three chips are part of the 11th generation Rocket Lake Desktop CPU family and will have the same 8-core, 16-thread, 16 MB L3 cache and 4 MB L2 cache core configuration. The difference here is the clock speeds and the TDPs for each respective chip.
Intel Core i9-11900K and Core i7-11700K will be the fastest unlocked CPUs in the 11th generation family and will rock a base TDP of 125W and a PL2 rating of 250W. Intel Core i9-11900 and Core i7-11700 are standard non-K SKUs with basic 65W TDP and PL2 rating of 225W. So let’s take a detailed look at the clock speed of these chips.
Intel Core i9-11900 8 Core Rocket Lake Desktop ES2 CPU
The Intel Core i9-11900 CPU test reported here has the ‘QVYE’ code name and is a BETA ES chip. The CPU runs with a base clock of 1.80 GHz and a boost clock of 4.5 GHz (1-Core) and 4.0 GHz (all-core). While this chip has the same clock speeds as the ES1 variant ‘QV1J’, the ES2 variant actually solves many errors that occur with the early variant and even maintains a higher and stable clock speed.
The leak reports that the CPU will be fully compatible with the PCIe Gen 4.0 interface and will also support memory overclocking and XMP support on the B560 motherboard when the retail chips hit the market. Interestingly, the performance is said to be on par with the Core i9-9900K and Core i7-10700K, both of which are 5.0-5.1 GHz 8 core components.
Intel Core i7-11700K 8 Core Rocket Lake Desktop ES2 CPU
By switching to the Intel Core i7-11700K, the chip ‘QV1K’ has the code name. It has clock speeds of 3.40 GHz base and 4.80 GHz (1-core) and 4.30 GHz (all-core) boost. The CPU has a TDP of 125W, but at boost frequencies the PL2 rating is 250W. The leak reports that there are samples running on up to 5.0 GHz boost clocks that are close to the 5.3 GHz boost that the Core i9-11900K will offer. The leak reports that the chip has an average power consumption of 160W in the bearing configuration.
Intel Core i7-11700 8 Core Rocket Lake Desktop ES1 CPU
Finally, the Core i7-11700 is still in ES1 ‘QV1J’ marked condition. This chip comes with a 1.80 GHz base clock, while boost clocks are reported at 4.4 GHz (1-core) and 3.8 GHz (full-core). The CPU has many errors in the ES1 state and cannot even support PCIe Gen 4.0. The memory is also locked to the standard 2133 MHz speed and cannot be surpassed.
The chip comes close to the Core i9-9900K even with such low clock speeds, which is mainly due in part to the new Cypress Cove architecture and their improved IPC over the aging Skylake design. The chip has an average power consumption of 120-130W, while the AVX-512 can push it up to 150-160W.

Intel Core i9-11900K 8 Core Rocket Lake Desktop CPU Alleged references
In addition to the Intel ES Rocket Lake CPU leaks, a Chiphell forum member has posted alleged performance values for the Core i9-11900K (Qualification Example). The chip was tested in various standard thread benchmarks which include CPU-z, Cinebench R23 and Cinebench R20. The following are the results via Harukaze5719 & 3DCenter:
Again, these are just alleged references, so take them with a grain of salt. But if they’s close to the real thing, the Core i9-11900K looks like an impressive chip, at least in 1T mode.
Here’s all we know about 11th generation desktop CPUs
Intel’s Rocket Lake-S desktop CPU platform will support the LGA 1200 connector, which debuted with 10th generation Comet Lake-S processors, but on motherboards in the 400 series. Intel Rocket Lake-S processors will primarily be launched for 500 Series motherboards, but it has been confirmed that LGA 1200 motherboards will offer support for Rocket Lake-S processors, especially considering that PCIe Gen 4.0 is a prominent feature in the Z490 motherboard that would only be enabled using Rocket Lake-S desktop CPUs. Motherboard manufacturers, especially ASUS, will pay extra attention to integrating PCIe Gen 4 hardware level integration on the Z590 series with motherboards compared to the Z490 series that we pointed out here.
Key features of Intel Rocket Lake Desktop processors include:
- Increased performance with new Cypress Cove core architecture
- Up to 8 cores and 16 threads (double-digit IPC gain over skylake)
- New Xe graphics architecture (up to 50% higher performance than Gen9)
- Increased DDR4 3200 MHz memory support
- CPU PCIe 4.0 lanes (available on motherboards Z490 and Z590)
- Enhanced display (integrated HDMI 2.0b, DP1.4a, HBR3)
- Added x4 CPU PCIe lanes = 20 total CPU PCIe 4.0 lanes
- Enhanced media (12 bit AV1 / HVEC, E2E compression)
- CPU-supplied storage or Intel Optane memory
- New features and overclocking capabilities
- USB audio relief
- Integrated CNVi & Wireless-AX
- Integrated USB 3.2 Gen 2×2 (20G)
- 2.5 GB Ethernet discrete LAN
- Discrete Intel Thunderbolt 4 (compatible with USB4)
The architecture for Rocket Lake processors is said to be Cypress Cove, which is reportedly a hybrid between Sunny Cove and Willow Cove designs, but has Xe Gen 12 GPU architecture. Intel’s Core i9-11900K will be the most important CPU offering in the series and expect more information about it soon. The Intel 500 Series motherboard platform is expected to hit store shelves on January 11.
