Intel’s 11th Generation Desktop CPU lineup codenamed Rocket Lake-S is launching next year and four models have their specifications leak out early on. The information was posted on Twitter by Davidbepo and turned into a useful chart by Harukaze5719 which gives us a look at the new CPUs and their respective specifications.
Intel Rocket Lake 11th Gen Core Desktop CPU Specifications Leak Out – Core i9-11900K Flagship With 8 Cypress Cove Cores, 5.3 GHz Clocks But 250W Power Limit
The Intel Rocket Lake-S Desktop CPU lineup will be featuring the brand new Cypress Cove cores. We have already got a hint of the performance potential of these chips and the specifications do cover the flagship along with the remaining unlocked ‘K’ series parts and a non-K series SKU too. The specifications for these chips are detailed below (Other specs via @OneRaichu).

Intel Core i9-11900K 8 Core & 16 Thread Rocket Lake Desktop CPU
The Intel Core i9-11900K will be the flagship 11th Gen Rocket Lake Desktop CPU. The chip is going to feature 8 cores and 16 threads. This will result in 16 MB of L3 cache (2 MB per core) and 4 MB of L2 cache (512 KB per core). In terms of boost clocks, we have already seen the CPU running at base frequencies of 3.5 GHz but as for boost, the CPU will feature a maximum boost clock of 5.2 GHz (1-core) while the all-core boost frequency will be maintained at 4.8 GHz.
The chip will also feature Thermal Velocity Boost which should deliver a 100 MHz jump in the max clock frequency. This should lead to a single-core boost clock of 5.3 GHz making it the first CPU to ever hit such a high frequency out of the box. However, do remember that regardless of using the Cypress Cove cores, the Core i9-11900K will feature lower cores and threads than the Intel Core i9-10900K. This is partially due to the backporting of Cypress Cove on the refined 14nm process node.
The CPU is said to feature a 1st stage power limit of 125W which is standard for a flagship Intel SKU and the 2nd stage power limit or PL2 is rated at 250W. This means that when hitting its maximum advertised clock speeds, the CPU could indeed be pulling the said amount of wattage from the PSU making it one of the most power-hungry 8-core chips ever produced. This might also explain why Intel didn’t go 10 cores and 20 threads on its 11th Gen lineup since it would’ve turned out to be a power-hungry monster of a chip breaking even past the 250W power limit.
Intel Core i7-11700K 8 Core & 16 Thread Rocket Lake Desktop CPU
Moving over to the Core i7, we see that Intel won’t be segmenting the core/thread count on a tier below Core i9. The Core i7-11700K features the same core configuration as the Core i9-11900K but comes with reduced clock speeds. The chip is said to feature a boost clock of 5.0 GHz on a single & 4.6 GHz across all of its 8 cores. The CPU will even carry the same amount of cache so nothing has changed but the main difference should come from the clocks and power limits. This lower-binned chip will sit at around 225-250W (PL2) limit while the PL1 limit will be standard at 125W.
It will be interesting to see how Rocket Lake CPUs overclock since the minute difference between the Core i9 and Core i7 chips can be overcome by a small overclock. As for pricing, the Core i7 will also be cheaper than the Core i9 variant but we don’t know yet how Intel will price its 8 core Rocket Lake-S Desktop CPUs yet. There are reports that Intel could aggressively price the chips at around $400 US for the Core i9 and $300 US for the Core i7 which could prove to be a great decision if they really want to go against AMD’s Zen 3 based parts in the sub-$500 US segment.
Intel Core i5-11600K 6 Core & 12 Thread Rocket Lake Desktop CPU
The Core i5-11600K is a 6 core chip with 12 threads. The Core i5-11600K should be going up against the AMD Ryzen 5 5600X which is a phenomenal CPU in its own right. The Core i5-11600K is said to feature a clock speed of 4.9 GHz on a single and 4.7 GHz across all cores. Do note that TVB won’t be available on SKUs below the Core i9 models so we shouldn’t expect an extended frequency limit on Core i7 and Core i5 SKUs. The chip will feature 12 MB of L3 cache and 3 MB of L2 cache.
Now the main proving ground for this chip against the AMD Ryzen 5 5600X will be its performance to price value. The Ryzen 5 5600X with a $299 US MSRP is slightly higher in terms of pricing when we compare it to its predecessor. The Core i5-11600K on the other hand will be replacing the Core i5-10600K which has a retail price of around $260 US.
If Intel sticks to its existing price strategy, then the Core i5-11600K could indeed become a hot selling chip in the mainstream gaming market. With that said, we also have to take into account the availability of the Core i5-11600K. Technically, mainstream SKUs aren’t affected a lot by supply issues as is the case with the Ryzen 5 5600X but a small delay in stock could result in Intel missing an opportunity to create a dent in AMD’s Ryzen 5 segment. Consumers have already seen what AMD delivered as a successor to its Ryzen 5 3600X so now it’s time to see what the Core i5-10600K’s successor can do.
Intel Core i5-11400 6 Core & 12 Thread Rocket Lake Desktop CPU
Lastly, we have the Core i5-11400 which is a locked and non-K 11th Gen Rocket Lake Desktop CPU. Intel isn’t moving away from locked chips anytime soon as doing so will gobble up sales of their K-series SKUs. The Core i5-11400 as such will be a 6 core and 12 thread chip with a similar core config as the Core i5-11600K but lower clock speeds of 4.4 GHz (1-core boost) and 4.2 GHz (all-core boost).
The chip will feature a standard 65W PL1 and 125W PL2 power limit. While the CPU technically does not support overclocking, motherboard vendors will be incorporating BIOS and features to raise the power limits of non-K SKUs for Rocket Lake chips. This would yield a higher base and more stable boost frequencies. So overall, you’ll be getting performance similar to the K-series SKUs at a lower price.
Here’s Everything We Know About The 11th Generation Desktop CPUs
Intel’s Rocket Lake-S desktop CPU platform is expected to feature support on LGA 1200 socket which will make its debut with Comet Lake-S CPUs although on 400-series motherboards. The Intel Rocket Lake-S processors will be launching alongside the 500-series motherboards but it has since been confirmed that LGA 1200 motherboards will offer support for Rocket Lake-S CPUs, especially given the fact that PCIe Gen 4.0 is a prominent feature of Z490 motherboards which would only be enabled with the use of Rocket Lake-S desktop CPUs.
Main features of Intel’s Rocket Lake Desktop CPUs include:
- Increased Performance with new Cypress Cove core 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 DDR4 3200 MHz Memory Support
- CPU PCIe 4.0 Lanes (Available on Z490 & Z590 Motherboards)
- 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 Attached Storage or Intel Optane Memory
- New Overclocking Features and Capabilities
- USB Audio offload
- Integrated CNVi & Wireless-AX
- Integrated USB 3.2 Gen 2×2 (20G)
- 2.5Gb Ethernet Discrete LAN
- Discrete Intel Thunderbolt 4 (USB4 Compliant)
The architecture for Rocket Lake CPUs is said to be Cypress Cove which is reportedly a hybrid between the Sunny Cove and Willow Cove design but will feature Xe Gen 12 GPU architecture. We have also been told that the Z590 motherboard series with Thunderbolt 4.0 support will be announced later this year so expect more information on Rocket Lake CPUs in the coming months.
