Description of the processor

The Intel Core i9-11900K is an 8-core processor, so it has 2 CPU cores less than its direct predecessor, the Intel Core i9-10900K. Intel has given the Intel Core i9-11900K a new architecture so that it is hardly slower (and even faster in some situations such as single-core load).

The base frequency of the processor is 3.5 GHz. When only one CPU core is loaded, the Intel Core i9-11900K can increase the frequency up to 5.3 GHz. 4.8 GHz is still possible if several cores are used to full capacity.

"Rocket Lake" is a backport on Intels old 14 nm production line. Actually, the architecture was developed for the 10 nm production. However, Intel still does not have enough capacity in the 10 nm lines, so that the desktop processors will still be manufactured in 14 nm in 2021. AMD has arrived at 7 nm, Apple with the M1 even at 5 nm. Nevertheless, Intel has its 14 nm production very well under control, which is also shown by the high clock frequencies of the Intel Core i9-11900K. Only the efficiency suffers a lot from the rough production.

In contrast, the Intel Core i9-11900K does surprisingly well in benchmarks and can compete with AMD and Apple under load on just one CPU core. In multi-core load scenarios, however, the processor has to admit defeat by AMDs 12 and 16 core processors.

The new desktop processors are finally allowed to use new iGPUs. The Intel XE graphics is a completely new development and has little in common with the old Intel UHD graphics cores. The iGPU is, however, pretty much reduced in the desktop processors from Intel, since Intel strongly limits the number of execution units here. The iGPU is currently not suitable for games, even in the form of the Intel XE. The mobile processors of the "Tiger Lake" architecture have the same graphics, but they can use significantly more execution units.
