a gaming CPU under Rocket Lake-S

Intel has been threatened by AMD with its Zen 3 CPUs and today we have the answer to all the questions. Is Intel over the top again? Is it possible that your Rocket Lake-S CPUs are once again at the top of performance? Today we have with us the CPU that is destined to compete in the most sought after sector: that of performance / price. Therefore, today we analyze the Intel Core i5-11400What is it capable of doing?

With this Intel Core i5-11400 we are facing a 6-core, 12-thread processor that promises a base frequency of 2.6 GHz and a Boost frequency of 4.4 GHz, all with 12 MB of L3 shared between all its cores.

Although it is not specified in the Intel specs, the L1 has undergone changes in its size, an important fact in the architecture. What has not changed has been its TDP of 65 watts, typical number of this range and that being its die welded to the IHS should have an effect on quite low temperatures as soon as the heatsink is good.

It is capable of supporting up to 128 GB of DDR4-3200 MHz in Gear 2 without overclock in Dual Channel configuration, with a maximum bandwidth of 50 GB / s. Of course and although it is late, this processor is fully compatible with PCIe 4.0 in a configuration of 1 x x16 and 1 x x4 lines, so that we can have a GPU and an SSD under said bus connected directly to the CPU.

It is logical that it is part of the LGA1200 socket like the rest of its brothers and it will also have technologies such as Intel DL Boost, Turbo Boost 2.0, Hyper Threading, VT-d, VT-x, Speed ​​Step, AES, OS Guard and Boot Guard, among other

Its MSRP price is 184 dollars, which should mean that it is offered below 200 euros in our country and with taxes included.

External analysis

Being somewhat strange and rare, Intel has supplied us with this processor through a KVX-signed kit that contains an ASUS H510E-M, a Kingston HyperX DDR4-3200 C16 module and an M.2 SSD, all in a Micro ATX box. Therefore, we will have to leave the comparative tests for later and focus on analyzing this CPU in said equipment.


The equipment is logically preassembled and will be analyzed as it has reached our hands.

Intel Core i5-11400 Benchmarks / Performance


Intel Core i5-11400 Conclusion


The performance of this CPU is within what is expected, although it slightly surpasses a direct rival like our i7-8700K despite having a lower frequency. The AIDA64 in RAM tests were done with our Corsair Vengeance RGB PRO DDR4-3200 MHz C16 to activate the dual channel, since the performance of the module in single channel was too low.

As we can see, the transfer rates are quite low and little expected, even when the BMI works perfectly in sync and with Gear 2.

The temperatures on the other hand are quite high, as a result of the Intel series heatsink, which, although it has been renewed once again, is still insufficient in terms of sound and performance. The average ranged between 65 degrees and 67 degrees, so we can expect a decrease in them as soon as we improve said cooling.

The equipment has been shown with certain problems of screen flickering or flickering, where the image came and went. Surprisingly that was only shown when we put in our RAM modules and after activating XMP.

With the original module it did not happen, and although BIOS, drivers and Windows were updated, it was not solved or we found the problem, which by the way was very annoying.
