The Intel Core i9-11900K is a flagship processor from Intel's 11th generation Rocket Lake-S family, which was released in March 2021. This processor is built on a 14nm process, and it's aimed at gamers and power users who demand the best performance from their PCs.
In this review, we will be taking an in-depth look at the i9-11900K, examining its features, performance, and value for money.
Features
The i9-11900K is a 16-thread processor with a base clock speed of 3.5 GHz and a turbo boost frequency of up to 5.3 GHz. It has 8 cores and 16 threads, and it supports Intel's Hyper-Threading technology, which allows for better performance in multithreaded applications.
One of the standout features of the i9-11900K is its support for PCIe 4.0, which provides faster data transfer speeds to compatible devices such as graphics cards and NVMe SSDs. The processor also supports DDR4 memory at speeds of up to 3200 MHz.
The i9-11900K has a TDP of 125 watts, which is higher than the previous generation i9-10900K's 95 watts. This means that the processor requires a more robust cooling solution to prevent overheating.
Performance
The i9-11900K offers excellent single-core performance, which is critical for gaming and other applications that rely heavily on single-threaded processing. In benchmarks, the i9-11900K outperforms the previous generation i9-10900K by up to 19%, thanks to its higher clock speeds and improved architecture.
However, the multi-core performance of the i9-11900K is not as impressive as its single-core performance. The 8-core processor struggles to keep up with its Ryzen 9 5900X counterpart, which has 12 cores and 24 threads. In multithreaded applications, the i9-11900K falls behind the Ryzen 9 5900X by up to 30%.
Value for Money
The i9-11900K is an expensive processor, with a retail price of around $550. This makes it significantly more expensive than its main competitor, the Ryzen 9 5900X, which retails for around $550.
When considering the i9-11900K's performance and value for money, it's important to note that it requires an expensive Z590 motherboard and fast DDR4 memory to perform at its best. When factoring in the cost of the entire system, the i9-11900K may not be the best value for money for most users.
Conclusion
The Intel Core i9-11900K is an excellent processor for gamers and power users who demand the best single-core performance from their PCs. Its support for PCIe 4.0 and DDR4 memory at high speeds makes it a future-proof investment.
However, the i9-11900K's multi-core performance falls short of its main competitor, the Ryzen 9 5900X. Its high price tag and the cost of a compatible Z590 motherboard and DDR4 memory also make it a less attractive option for many users.
Overall, the i9-11900K is a powerful processor that delivers excellent single-core performance, but it may not be the best value for money for most users.
