Intel Core i9-11900K May be the New King of Single-thread Performance

Thanks to leaks from several sources, we learned some details about the performance of Intel's new processors - Core i9-11900K and Core i7-11700K.

IN A NUTSHELL:

  1. According to a leak, in single-threaded applications, the Core i9-11900K is 19% faster than Core i9-10900K and 3% faster than Ryzen 9 5950X;
  2. Results in multicore tests are less impressive;
  3. The Core i7-11700K also performs well in the benchmarks - while working on single thread, it performs about 18% better than its predecessor, offering performance close to that of the competitive flagship.

The results of Intel Core i9-11900K and Intel Core i7-11700K in the CPU-Z benchmark (via Guru3D) appeared on the web. In single-threaded benchmark, Intel's new CPU achieved a score of 695 points - about 19% bigger than its predecessor (Core i9-10900K). After overclocking to 5.2 GHz the result was even better (706.3 points).

In the case of Core i7-11700K the exact results were blurred out, but they are between 671-679 (single thread) and 6301-6399 (multi-thread).

The editors of Guru 3D compared the performance of Core i9-11900K with other CPUs. It seems that Intel's CPUs are 3% faster than Ryzen 9 5950X - at least in single-threaded performance. In the case of multithreaded apps, Core i9-11900K achieved 6522.1 / 7198.8 points (the second result is for performance after overclocking). This means that in this area AMD's flagship processor retains the advantage, which is not surprising given that Intel's unit has eight cores and Ryzen 9 5950X sixteen.

The advantage of Core i7-11700K over Core i7-10700K is about 18%, which suggests that when working on single thread the processor will offer performance comparable to Ryzen 9 5950X. This is a solid result, but it is worth remembering that the benchmark results come from unofficial sources and should be taken with a grain of salt. What's more, the tested CPUs are engineering samples - the devices that will eventually reach customers can offer even better performance.

We also have a leak concerning a possible release date for Intel's new processors. According to user Uniko Hardware, they will debut on March 15, this year. Earlier, on January 11, we'll see the launch of the 500 series motherboards, which will work with the CPUs in question (although it's worth noting that they will also work with existing models based on LGA 1200 socket - the 400 series).
