OPTICXCESS — Intel Core i9-11900K: Detailed Performance Specifications

The Intel Core i9-11900K is officially available globally on March 30, 2021, where there are major changes that this flagship Intel flagship desktop processor brings to gamer enthusiasts and content creators alike.

Initially announced, this processor brings joy to fans, and could be Intel’s solution to fight against the big flow of AMD with the Ryzen 5000 series.

Built based on the new 14nm Cypress Cove architecture which is claimed to provide up to 19% Instructions-per-cycle compared to the previous generation, it is certainly very promising. On the other hand, Intel also brings a new complete integrated GPU package which is also claimed to provide superior performance by a difference of up to 50%.

The presence of Intel UHD 750 graphics with the main Xe Graphic feature will be something interesting to reveal. It could even be a new rival to the Radeon Vega from the Ryzen G Series.

Intel Core i9-11900K specifications

The Intel Core i9-11900K processor itself has the power of 8 cores and 16 threads – a drop down from the 10 cores previously present in the 10th generation. However, the higher clockspeed is up to 5.3 GHz single-core and 4.8 GHz all-core turbo. Intel confirmed a new PCIe configuration, with support for PCIe 4.0 and 20 lanes directly from the CPU.

But why did the number of cores have to go down? According to techspot, generally, when companies come up with new architectures that create larger CPU cores, they counter the increased power requirements by switching to smaller process nodes. In many cases, the smaller the number of cores can be more efficient (or at least the claim will keep the CPU less power-hungry).

However, the TDP is quite large up to 125W and it seems that users need the best CPU Cooler to be able to hold this processor power to the maximum. On the other hand, much higher memory support also applies to dual channel DDR4 3200Mhz, including max memory that can accommodate up to 128GB.

Conclusion

We thought at first this processor was very promising, especially for gaming at a much cheaper price than the previous generation. However, it turns out that it is far from the expectations of fans or even consumers as a whole. The single core performance is still very good, it’s just that it can’t catch up with what the Ryzen 5000 series processors can offer. Even to be able to fully compete with the Ryzen 7 5800X even though it has a small price difference. The most uncomfortable thing is of course the power consumption, which we think is much greater than what the Intel Core 10900K has ever offered, especially when all cores are in the highest clockspeed.

Recommendation? of course there is, but we think the 10th gen option is still much better, or it’s better to take the 11700K series which has almost the same specifications at a much cheaper price value. Or, just skip it and wait for the next generation of Alder Lake 10nm to wait?
