One of the Chinese stage enthusiasts Chiphole Two future Intel processors gave rocket Lake-S series test results – the Core i5-11600KF and Core i5-11400F models. Both chips have 6 cores and 12 threads, which lack the integrated Intel XE graphics core, and support prior manual overclocking.
The announced nominal TDP level of the Core i5-11600KF model is 125 watts. According to the CPU-Z program, the base frequency of the processor is 3.9 GHz. In auto overclocking mode, it can go up to 4.9 GHz. In turn, the Core i5-11400F model has a TDP of 65 W, a base frequency of 2.6 GHz, and a Boost frequency of up to 4.4 GHz. Both chips are based on the new Cypress Cove architecture and provide full PCI Express 4.0 support.
The processor was tested on a Gigabyte Z490 Arrow Ultra motherboard with the latest BIOS to support 11th gen Intel Core chips. It is highly likely that the motherboard manufacturer will release a more customized version of the microcode just before the official launch of the Rocket Lake-S series on 30 March. Also, the system used 16 GB ZADAK Spark DDR4-3600 RAM.
The processor was cooled by a three-fan LSS PCCooler GI-CX360 ARGB, which was expanded to 350 volts. In other words, in theory, this system should be more than sufficient to cool Core i5 series chips, even taking into account their PL2 index.
Under the weight of synthetic test AIDA64, the Core i5-11600KF model consumed 209 watts of power and heated to 85 ° C. For the Core i5-11400F, in turn, power consumption is declared at 145 W and a temperature of 70 ° C in the same test. The performance results of chips in various synthetic benchmarks can be found below.
The Chinese observer noted that with the release of the new processor, the performance of both processors may improve before the official release. For this reason, he did not conduct sports tests.

However, they tried to manually overclock the Core i5-11600KF. The results were interesting. When the frequency in all cores was set to 4.8 and 4.9 GHz, and the voltage was set to 1.4 V, the processor behaved unsteadily. The chip temperature rose significantly, so the enthusiasts gave up. The Core i5-11400F model does not have support for manual overclocking, but in principle, chip performance can still be improved by adjusting PL2 and tau states. The enthusiasts did not do so.
