Intel Core i9 11th Generation "Rocket Lake" Processors

by Abhijeet Kumar

The new "Rocket Lake" Core i9-11900k, Intel's mainstream 11th Generation flagship desktop CPU is for die-hard gamers and Intel loyalists they can safely opt for the "Rocket Lake" Core i9-11900K. This desktop CPU is made of silicon. It has very fast single threaded speed.

The Core i9-11900K, while impressive in single-threaded tasks, it's too power-hungry, and not stable enough under stress to remain competitive with AMD's Ryzen desktop-CPU offerings, or even Intel's own previous-generation CPUs, such as the 10th Generation Core flagship, the Core i9-10900K.

We have taken some comparisions to see which chip rises to the top. Let's see how they stack up.

Ryzen 9 5900X vs Intel Core i9-11900K Features and Specifications

  Cores / Threads Base (GHz) Peak Boost (Dual/All Core) TDP iGPU Cache
Ryzen 9 5900X 12 / 24 3.7 4.8 105 watts None 64 MB
Intel Core i9-11900K (KF) 8 / 16 3.5 5.3 / 4.8 (TVB) 125 watts UHD Graphics 750 Xe 32EU 16 MB

The Core i9-11900K comes with eight cores and 16 threads, which is two fewer cores than the previous-gen Core i9-10900K and four cores behind the Ryzen 9 5900X. Core counts aren't the end-all-be-all, of course, as different architectures deliver varying levels of performance per core. AMD's Zen 3 cores are still slightly faster than Rocket Lake in most work, though the latter does pull out a few wins. Basically, we should regard the Rocket Lake cores and Zen 3 cores as pretty closely matched, so with four additional cores, the Ryzen 9 5900X should win in most of our threaded benchmarks.

The 11900K does have one big advantage over the Ryzen 9 5900X: The new UHD Graphics 750 comes armed with 32 EUs based on the Xe graphics engine, whereas all Ryzen 5000 processors come without integrated graphics. That means that if you don't have a discrete GPU, Intel wins by default. You could also buy Intel's 19-11900KF, which comes with a disabled graphics engine, for $23 less.

In sum, the strength of AMD's latest Ryzen 7 and 9 5000 Series chips is impossible to ignore. In Intel's defense, the AMD Ryzen 7 5800X is a spectacular eight-core processor, one of the best we've ever seen, and to hit (or even come close to hitting) that bar on an aged-out lithography would be something special on Intel's part. That will have to wait, perhaps, for 12th Generation Core.
