Intel Core and AMD Ryzen

When it comes to AMD Ryzen 9 5900X vs Intel Core i9-11900K, you may want to know about these two brands.

Intel was the absolutely undisputed leader throughout the 2010s, but things have changed dramatically in the last few years. In 2017, AMD has released its first Ryzen CPUs, and now the 3rd generation Ryzen has proven to be a strong competitor for Intel’s 9th generation Core CPUs.

In the market of desktop CPUs, the two major players are Intel and AMD now.

The series of Intel Core mainly include:

  • Low-end: Core i3 series
  • Middle & high-end: Core i5 and i7 series
  • High-end: Core i9 series

The series of AMD Ryzen mainly include:

  • Low-end: Ryzen R3 series
  • Middle & high-end: Ryzen R5 and R7 series
  • High-end: Ryzen R9 series

There are many products from the two brands. You may not be able to choose the best one from them, but you can choose the one that best fits your needs. Continue to read this post to get the information about 5900X vs 11900K.

11900K vs 5900X: Specification

The Intel Core i9-11900K was released in 2021, while the AMD Ryzen 9 5900X was released in 2020.

Just read the table below to know the details about AMD Ryzen 9 5900X vs Intel Core i9-11900K.

Intel Core i9-11900K AMD Ryzen 9 5900X
Core Counts 8 12
Threads Counts 16 24
Core Speed 3.5GHz 3.7GHz
L1 Cache (per core) 96KB 64KB
L2 Cache (per core) 512KB 512KB
L3 Cache 16MB 64MB
TDP 125w 105w
RRP $539 $549
  • Cores/Threads/Core Speed: CPUs with higher core and thread counts are more efficient at multitasking natively. Besides, the core speed represents how faster your computer can run. With 12 cores 24 threads, and 3.7GHz core speed, 5900X is the winner in the 5900X vs 11900K.
  • Cache: L1 cache is the fastest memory. It has the data the CPU is most likely to need while completing a certain task. L2 cache lags behind the L1 cache but is still much faster than RAM. L3 cache is the largest but the slowest cache memory unit.
  • TDP: It is short for Thermal Design Power, and is used to measure the heat output expected from the component under load. The higher the TDP, the more heat is generated by the CPU. You can find that the AMD Ryzen 9 5900X is the winner from the table.

11900K vs 5900X: Gaming Performance

How about the 5900X vs 11900K in the gaming performance?

At launch, the Intel Core i9-11900K claimed that its single-core performance would improve by 32% over its predecessor. In that sense, 11900K beats 5900X. However, in the process of using, the situation is somewhat different.

In some CPU-heavy games like the Shadow of the Tomb and Far Cry 5, the Intel Core i9-11900K does perform better than the AMD Ryzen 9 5900X. But in some older or less CPU-demanding games like CS, the AMD Ryzen 9 5900X still outperforms its Intel rival.

It's worth noting that the 11900K underperforms the 10900K in some games. It’s hard to find the reason. The new product has just been released, so some performances require further tests.

11900K vs 5900X: Application Performance

The application performance of the AMD Ryzen 9 5900X vs Intel Core i9-11900K could be divided into 2 cases: single-thread and multithread.

In the single-thread test, the Intel Core i9-11900K is the winner. It has incredible performance in many tests such as LAME and FLAC encoders, as well as Cinebench 23 and POV-Ray renderers.

With a greater number of cores and a larger L3 cache, the AMD Ryzen 9 5900X beats the Intel Core i9-11900K in any test of multithread.

Despite 11900K overheads 5900X in the test of single-core, the AMD Ryzen 9 5900X brings more tangible performance gains in real use.
