Intel’s Core i5 Rocket Lake processors, which include the Core i5-11600KF and Core i5-11400F 6 Core chips, were compared and their performance results were leaked to Chinese Chiphell Forums (via Harukaze5719). Both CPUs are part of the 11th Gen Core i5 family and each contain 6 core and 12 wires.
Intel Core i5-11600KF & Core i5-11400F 6 Core Rocket Lake Desktop CPU Criterion Leaked
The Intel Core i5 Rocket Lake processors will be the choice for main players. The CPUs will compete with the AMD Ryzen 5 series, which also contains 6 cores and 12 wires and has the 5600X and the 5600 as the main competition. The following are the specifications of both CPUs in detail.
Intel Core i5-11600KF 6 Core & 12 thread Rocket Lake Desktop CPU
The Intel Core i5-11600K is a 12-core 6-core chip. The processor has to perform against the AMD Ryzen 5 5600X, which in itself is a phenomenal CPU. The Core i5-11600K is said to have a clock speed of 4.9 GHz on a single and 4.6 GHz across all cores. Note that TVB is not available on SKUs under the Core i9 models, so we should not expect an extended frequency limitation on Core i7 and Core i5 SKUs. The chip contains 12 MB L3 cache and 3 MB L2 cache.
The most important evidence for this disc against the AMD Ryzen 5 5600X is the performance at price value. The Ryzen 5 5600X with a $ 299 US MSRP is slightly higher in terms of prices when we compare it with its predecessor. The Core i5-11600K, on the other hand, replaces the Core i5-10600K with a retail price of around $ 260 US.
If Intel sticks to its existing pricing strategy, the Core i5-11600K could indeed become a strong selling point in the mainstream market. With that said, we should also consider the availability of the Core i5-11600K. Technically, mainstream SKUs are not much affected by supply issues, as is the case with the Ryzen 5 5600X, but a small lag in inventory could lead to Intel missing an opportunity to dive into AMD’s Ryzen 5 segment create. Consumers have already seen what AMD has delivered as a successor to its Ryzen 5 3600X. It’s now time to see what the Core i5-10600K’s successor can do.
Intel Core i5-11400F 6 Core & 12 thread Rocket Lake Desktop CPU
The Intel Core i5-11400F is a closed and non-K 11th Rocket Lake Desktop CPU. Intel will not be moving away from closed discs any time soon, as it will increase sales of their K-series SKUs. The Core i5-11400 as such will be a 6-core and 12-wire chip with a similar core configuration to the Core i5-11600K, but lower clock speeds of 4.4 GHz (1-core boost) and 4.2 GHz (all-core) core boost) for the Core i5-11400.
The chip has a standard 65W PL1 and 125W PL2 power limit. Although the CPU does not technically support overclocking, motherboard vendors will use BIOS and features to increase the power constraints of non-K SKUs for Rocket Lake chips. This will provide a higher base and more stable boost frequencies. In general, you will achieve similar performance as the K-series SKUs at a lower price.
Intel Core i5-11600KF & Core i5-11400F Rocket Lake 6 Core CPU Performance Measures
The Intel Core i5-11600KF and Core i5-11400F have no integrated graphics, so they have the ‘F’ label. To test, the tester used the Gigabyte Z490 AORUS Ultra motherboard with the latest BIOS, a 16 GB memory kit consisting of DIMMs rated on DDR4-3600 (CL17-19-19-39), and a 360 mm AIO liquid cooler with a 350 W cooling capacity. The cooler should be enough to handle both chips, as the Core i5-11600KF reaches a peak of PL2 of about 220-225W. The criteria can be seen below:
In terms of power and temperatures, the tester also tested both Intel Rocket Lake Desktop CPUs within AIDA64. The Core i5-11600KF peaks 210W with a maximum reported temperature of 85C, while the Core i5-11400 peaks 145W with a maximum reported temperature of 70C. The tester also tried to overclock the Core i5-11600KF, but the BIOS or chip (ES sample) was not stable and could only run 4.8 GHz at 1.325V, resulting in higher temperatures and power consumption .
In addition to these tests, YouTuber, the hardware corner of Tobi, simulated the performance of the Core i5-11600K, but eliminated two cores on its Intel Core i7-11700K CPU. The Core i7 still has a larger memory than the Core i5-11600K, but it gives you a good preview of the Core i5-11600K versus an AMD Ryzen 5 5600X CPU. The user has tested several games with both processors with the same 4.6 GHz speeds and Rocket Lake appears to be faster than the Zen 3 offering. You can watch the full video of the tests below:
The Intel Rocket Lake Desktop CPUs will be launched on March 30, but pre-orders will be open on March 16. Please note that reviews for the slide will also only be published on March 30th.
