11900k vs 5900x

Edit-01/05/2021-After Intel updated the BIOS, the performance of 11900K has been significantly improved compared to the following figure. Based on third-party testing, while the 5900X is still the clear overall winner, easily beating the 11900K in most games, CPU performance is now roughly 10% higher than previous performance. We will run our own benchmarks to test the performance of this update ourselves; Once we have it, we will update the following figures accordingly. Update

The following is a comparison of Intel 11900K and AMD 5900X specifications. Intel 10900K is also included for reference.

The CPU dispute between Intel and AMD did not come out of thin air. This is the next battle in the endless war that started in 2017. AMD released its first Ryzen CPU and established itself as a competitor in the market.

Intel still occupies an absolute dominant position in the market share. Until recently, with its powerful single-core performance, its products were considered the best gaming CPUs. Historically, AMD has focused on multi-threading excellence, creating incredibly versatile CPUs, but its 5000 series changed everything and took over Intel’s last stronghold... gaming advantage. With the launch of i9 11900K, we finally witnessed Intel's counterattack.

With the rise and fall of these companies, leading each other, there is some consistency that can be discussed. AMD chips are generally more affordable and are almost always backward compatible. Most Intel chips are only compatible with new sockets. We will discuss later if this is the case this time.

is responsible for most of the processing and execution of instructions. The core is the most important part of the CPU. Its format and richness define the functions and functions of the computer, making it an ideal place to start comparisons.

Ryzen 9 5900X has 12 huge cores. Many people think this is an overkill for today's gaming environment, and to some extent it is true, but another word for overkill is future-oriented. With this monster chip, you can be ready for years of game release. It is said that

Intel will remain stable, and 11900K will have 8 cores. Although this is sufficient for gaming, it provides AMD with a quad-core advantage. Although it is said that due to the 14nm Cypress Hill core structure, the gentogen efficiency from Coffee to Rocket Lake has some major improvements, but it must perform very well to keep up with the 5900X. The

chips are also multi-threaded (or hyperthreading, if you like), a technology that essentially splits one core in two, allowing it to process almost twice as many instructions per cycle. Multi-threaded tends to increase latency, but at the moment CPUs with single-threaded performance faster than 5900X are 5950X and Apple's new M1 processor.

When evaluating hypothetical CPU performance, clock speed is the second most revealing specification. Basically, they determine how fast your CPU can run. In terms of gaming, a faster clock speed equates to a more sensitive and smooth experience. The basic frequency of the

5900X is 3.7GHz, and the boost clock is 4.8GHz. Considering that the sweet spot of modern games is between 3.5 and 4GHz, we once again see the Ryzen chips that may be considered exaggerated. The

i9 chip is said to have a 3.5GHz base clock, and due to Intel’s new thermal speed boosting technology, the 5.2GHz boost clock is crazy! We can’t say with confidence whether this will bring the i9’s performance to the same level as the 5900X, but it’s certainly starting to look like there may be a glimmer of hope. The

Ryzen chip is a product of its flagship Zen 3 micro-architecture. Unlike Intel it seems that it has never made major architectural changes in a hop, AMD has actually completely overhauled its entire process, reducing latency (its only flaw in the past), higher IPC, and zero increase in power consumption. The

5900X is built on AMD's small 7nm process and has 6MB L2 and 64MB L3 caches to ensure your game doesn't miss a beat. It is also backwards compatible with AM4 plugs, so you can save yourself some money and bills in this regard because it only has 105 watts of power. With support for DDR43200 memory, this chip has some of the fastest data transfers in computer and other games.

i9 11900K is our first introduction to Intel's Rocket Lake architecture. To be fair, they seem to have made some major changes, one being backward compatibility. The Z590 chipset developed together with the 11900K is under development, but the CPU will be used in conjunction with the LGA 1200 socket. You can also expect 10% to 19% higher CPI, which supports the same DDR43200 memory as the 5900X, but the cache capacity is well below AMD's level.

Multitasking from AMD has been popular for many years, making it a favorite in the professional field. It's not that Intel CPUs can't handle multitasking, they're just a multithreaded monster far inferior to AMD, and they don't look like

Just like in a juggling competition, a person with two arms faces a person with six arms. Even if it competes fairly and provides them with 8 cores and 16 threads, AMD chips will still be more capable of supporting parallel workflows. This is just its design purpose.

Unsurprisingly, Intel 11900K leads again, even in single-core tests.

Overall, the 5900X is an excellent workstation CPU, although since Intel's focus on the 11900K has always been single-core heavy gaming and activities, they believe they can get a leg up on these activities, so is to be expected. Although

claims the 11900K's single-core performance to be 32% higher than its predecessor, which is enough to be ahead of the 5900X, our gaming tests at launch did not support it at all.

Surprisingly, in some of the games we tested, the 11900K didn't perform as well as the old 10900K, but it managed to beat the Ryzen 9 5900X more times than it lost, especially in games like Tomb Raider. games like Shadow of Shadow and Far Cry 5. Having said that, some games, like Red Dead Redemption 2, have a balance between the two tiles. In fact, in outdated, less CPU-intensive games like CS: Go, we actually believe that AMD processors perform better than their Intel competitors. Given that the architectural improvements declared by Intel are really puzzling. Chapter

Why Is This? The current argument is that since the CPU was just released, the poor performance is the result of 11900K compatibility issues, and more BIOS and firmware updates will unlock the true potential of the chip. For now, this is a wait and see game, but the first results are certainly disappointing for Intel!

As shown in the test above, in terms of multi-core performance, 5900X has a significant advantage over 11900K; This is not surprising, so if you are interested in building workstation PCs then the 5900X is definitely your choice.

The game screen is muddy. Although 11900K is definitely better than 10900K in terms of single-core performance on paper, and outperforms 5900X in this department, 5900X outperforms Intel 11900K in terms of actual game FPS, though it loses to Intel 11900K. In fact, in older games with lower CPU usage, the 5900X seems to have an advantage. Maybe more firmware updates will change this and unlock some of the additional 11900K potential, but this is how we found it in our review.

Considering that the current price of both CPUs is around $ 10, we can see that if you plan to keep the CPU in stock configuration, there is not much reason to choose 11900K instead of 5900X. Where 11900K can come into play is in the overclocking department. Although we can't give a clear recommendation on this before further testing, the extra clock speed of the 11900K overclocking may make it an excellent graphics card for gaming-focused consumers.
