Intel’s Rocket Lake desktop CPUs (including Core i9-11900, Core i7-11700 and Core i7-11700K) leaked again in Bilibili (via Harukaze5719). The 11th generation chips are still ES units, but have a higher clock speed because they are the second ES2 variant compared to the ES1 variants we saw before.
Intel Core i9-11900, Core i7-11700 7 Core i7-11700K 8 Core Rocket Lake desktop CPU leaked again
All three chips are part of the 11th generation Rocket Lake desktop CPU series and will have the same core configuration, including 8 cores, 16 threads, 16 MB of L3 cache and 4 MB of L2 cache. The difference here is the clock speed and TDP of each corresponding chip.
Intel Core i9-11900K and Core i7-11700K will be the fastest unlocked CPU in the 11th generation family, with a basic TDP of 125W and a PL2 rating of 250W. Intel Core i9-11900 and Core i7-11700 are standard non-K SKUs with a basic TDP of 65W and a PL2 rating of 225W. So let us understand the clock speed of these chips in detail.
Intel Core i9-11900 8-core Rocket Lake desktop ES2 CPU
The Intel Core i9-11900 CPU example reported here has the “QVYE” codename and is a BETA ES chip. The base clock of the CPU is 1.80 GHz, and the rated value of the boost clock is 4.5 GHz (1 core) and 4.0 GHz (full core). Although the clock speed of this chip is the same as the ES1 variant “QV1J”, the ES2 variant actually fixes many of the errors encountered by the earlier variants and even maintains a higher and stable clock speed.
The leaker reported that when the retail chip is on the market, the CPU will be fully compliant with PCIe Gen 4.0 interface, and will also support memory overclocking and XMP support on the B560 motherboard. Interestingly, the performance is said to be comparable to 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
Moved to Intel Core i7-11700K, the chip has the code name “QV1K”. Its clock speed is 3.40 GHz base and 4.80 GHz (1 core) and 4.30 GHz (full core) enhancement. The TDP of the CPU is 125W, but at the boost frequency, the PL2 is rated at 250W. The leaker reported that some samples run with a boost clock up to 5.0 GHz, which is close to the 5.3 GHz boost clock that the Core i9-11900K will provide. The leaker reported that the average power consumption of the chip’s standby configuration was 160W.
Intel Core i7-11700 8-core Rocket Lake desktop ES1 CPU
Finally, the Core i7-11700 is still in the ES1’QV1J’ status. The chip has a base clock of 1.80 GHz, while the boost clock is reported as 4.4 GHz (1 core) and 3.8 GHz (full core). The CPU has many errors in ES1 state, and it cannot even support PCIe Gen 4.0. The memory is also locked to the default 2133 MHz speed and cannot be exceeded.
Even at such a low clock speed, the chip is indeed close to Core i9-9900K, which is largely due to the new Cypress Cove architecture and its improved IPC in the aging Skylake design. The average power consumption of the chip is 120-130W, and AVX-512 can increase it to 150-160W.

Intel Core i9-11900K 8 Core Rocket Lake desktop CPU benchmark test
In addition to the Intel ES Rocket Lake CPU leak, Chiphell Forum members also released the so-called Core i9-11900K performance benchmark (eligibility sample). The chip has passed various single-threaded benchmark tests, including CPU-z, Cinebench R23 and Cinebench R20. The following are the results obtained through Harukaze5719 and 3DCenter:
Again, these are just so-called benchmarks, so please bring a little salt. However, if they are very close to the real thing, at least in 1T mode, the Core i9-11900K looks like an impressive chip.
This is all we know about the 11th generation desktop CPU
Intel’s Rocket Lake-S desktop CPU platform will support the LGA 1200 socket, which first appeared on the 10th-generation Comet Lake-S CPU, albeit on the 400 series motherboard. Intel Rocket Lake-S processors will be mainly launched for 500 series motherboards, but it has been confirmed that LGA 1200 motherboards will support Rocket Lake-S CPUs, especially considering that PCIe Gen 4.0 is a prominent feature of Z490. A motherboard that can only be enabled by using Rocket Lake-S desktop CPU. Motherboard manufacturers, especially Asustek, will pay special attention to the hardware-level integration of PCIe Gen 4 on Z590 series motherboards and Z490 series motherboards.
The main functions of Intel Rocket Lake desktop CPU include:
- New Cypress Cove core architecture improves performance
- Up to 8 cores and 16 threads (double-digit IPC gain on Skylake)
- Brand new Xe graphics architecture (50% higher performance than Gen9)
- Added support for DDR4 3200 MHz memory
- CPU PCIe 4.0 channel (available on Z490 and Z590 motherboards)
- Enhanced display (integrated HDMI 2.0b, DP1.4a, HBR3)
- Increased x4 CPU PCIe lanes = 20 total CPU PCIe 4.0 lanes
- Enhanced media (12-bit AV1/HVEC, end-to-end compression)
- CPU additional storage or Intel Optane memory
- New overclocking function
- USB audio uninstall
- Integrate CNVi and Wireless-AX
- Integrated USB 3.2 Gen 2×2 (20G)
- 2.5Gb Ethernet Discrete LAN
- Discrete Intel Thunderbolt 4 (compatible with USB4)
It is said that the architecture of Rocket Lake CPU is Cypress Cove. It is said that it is a hybrid of Sunny Cove and Willow Cove designs, but it will use Xe Gen 12 GPU architecture. Intel’s Core i9-11900K will become the flagship CPU product in this series, and hope to get more information soon. Currently, the Intel 500 series motherboard platform is expected to be listed on January 11.
