Intel’s Rocket Lake Desktop CPUs that include the Core i9-11900, Core i7-11700 and Core i7-11700K have leaked once again in Bilibili (via Harukaze5719) The 11th generation chips are still ES units, but they come with much higher clock speeds, since they are in the second ES2 variation 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 leak again
All three chips are part of the 11th generation Rocket Lake Desktop CPU family and will feature the same core configuration of 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 and Core i7-11700K will be the fastest unlocked CPUs in 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 PL2 ratings of 225W. So, let’s take a detailed look at the clock speeds of these chips.
Intel Core i9-11900 8 Core Rocket Lake Desktop ES2 CPU
The Intel Core i9-11900 example reported here is codenamed ‘QVYE’ and is a BETA ES chip. The CPU works with a base clock of 1.80 GHz and a boost clock rated at 4.5 GHz (1 core) and 4.0 GHz (all cores). Although this chip has the same clock speed as the ES1 variant ‘QV1J’, the ES2 variant corrects many bugs found with the previous variant and still maintains a higher and more stable clock speed.
The leaker 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 B560 motherboards when retail chips hit the market. Interestingly, the performance is considered equal to that of Core i9-9900K and Core i7-10700K, both with 8 cores of 5.0-5.1 GHz.
Intel Core i7-11700K 8 Core Rocket Lake Desktop ES2 CPU
Moving on to the Intel Core i7-11700K, the chip is codenamed ‘QV1K’. It has a base clock speed of 3.40 GHz and an increase of 4.80 GHz (1 core) and 4.30 GHz (all core). 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 5.0 GHz boost watches that are close to the 5.3 GHz boost that the Core i9-11900K will be offering. The leak reports that the chip has an average power consumption of 160 W in its standard configuration.
Intel Core i7-11700 CPU 8 Core Rocket Lake Desktop ES1
Finally, there is the Core i7-11700 which is still in the state labeled ES1 ‘QV1J’. This chip comes with a base clock of 1.80 GHz, while boost clocks are reported at 4.4 GHz (1 core) and 3.8 GHz (all cores). The CPU has many bugs in the ES1 state and does not even support PCIe Gen 4.0. The memory is also locked at the standard speed of 2133 MHz and cannot be exceeded.
The chip comes close to the Core i9-9900K even at such low clock speeds, which is mainly due in part to the new Cypress Cove architecture and its improved IPC over the aged Skylake design. The chip has an average power consumption of 120-130W, while the AVX-512 can increase to 150-160W.

Supposed Intel Core i9-11900K 8 Core Rocket Lake Desktop CPU benchmarks
In addition to the Intel ES Rocket Lake CPU leaks, a Chiphell forum member posted alleged Core i9-11900K performance benchmarks (qualification sample). The chip has been tested on several single-thread benchmarks that include CPU-z, Cinebench R23 and Cinebench R20. The following are the results via Harukaze5719 AND 3DCenter:
Again, these are just supposed benchmarks, so consider them carefully. But if they look like the real thing, then the Core i9-11900K seems to be an impressive chip, at least in 1Q mode.
Here’s everything we know about 11th generation desktop CPUs
Intel’s Rocket Lake-S desktop CPU platform will be supported on the LGA 1200 socket, which made its debut with 10th generation Comet Lake-S CPUs, albeit on 400 series motherboards. Intel Rocket Lake-S processors will be released primarily for 500 series motherboards, but it has been confirmed that LGA 1200 motherboards will support Rocket Lake-S CPUs, especially considering the fact that PCIe Gen 4.0 is an important feature of Z490 motherboards that they would only be enabled using Rocket Lake-S desktop CPUs. Motherboard manufacturers, especially ASUS, will be paying extra attention by incorporating hardware-level integration of PCIe Gen 4 into their Z590 line of motherboards compared to their Z490 line, as we point out here.
Key features of Intel’s Rocket Lake Desktop CPUs include:
- Higher performance with Cypress Cove’s new flagship architecture
- Up to 8 cores and 16 threads (double-digit IPC gains over Skylake)
- New Xe graphics architecture (up to 50% higher performance than Gen9)
- Increased 3200 MHz DDR4 memory support
- PCIe 4.0 CPU ranges (available on Z490 and Z590 motherboards)
- Enhanced display (integrated HDMI 2.0b, DP1.4a, HBR3)
- Added PCIe x4 lanes on the CPU = 20 PCIe 4.0 lanes on the total CPU
- Advanced media (12-bit AV1 / HVEC, E2E compression)
- CPU Attached Storage or Intel Optane Memory
- New features and overclocking capabilities
- USB audio download
- Integrated CNVi and Wireless-AX
- USB 3.2 Gen 2×2 (20G) integrated
- 2.5 Gb discrete Ethernet LAN
- Discreet Intel Thunderbolt 4 (USB4 compatible)
The architecture for Rocket Lake CPUs is Cypress Cove, which is a hybrid between the design of Sunny Cove and Willow Cove, but will feature the Xe Gen 12 GPU architecture. Intel’s Core i9-11900K will be the car- head of the line and we expect more information soon. The Intel 500 series motherboard platform, for now, is expected to hit stores on January 11.
