Edit-May 1, 2021-After the Intel BIOS update, the performance of 11900K is significantly improved compared to the figure below. According to third-party tests, in many games, the CPU is now up to 10% more than the previous 10900K generation. We will conduct our own benchmark tests to test the upgraded performance ourselves; once we have it, we will update the following figures accordingly. Update

Brand new Intel Core i9 11900K CPU is here! The blue team’s new flagship processor aims to improve its previous popular product 10900K, while also challenging its rival AMD Ryzen 9 5900X’s flagship CPU.

We made a side-by-side comparison and review of two Intel processors: the 10th and 11th generations, Comet Lake and Rocket Lake.

Considering all relevant information, statistics, specifications, and most important benchmark results, this article will look at the older Intel Core i9 10900K and the newer Intel Core i9 11900K to see what improvements we are considering. (If applicable) In terms of game performance and workstation tasks.

When it comes to gaming thrones, Intel and AMD often come and go, taking the top spot in computer processing units. Since 2017, these two competing brands have been at the forefront of CPU manufacturing, vying for greater market share.

The upcoming i9 11900K provides another rival for AMD’s 5900X CPU. It is the Ryzen 5000 series processor, which briefly interrupted Intel’s previous unilateral control of the CPU gaming market. Is this an opportunity for Intel to restore a temporarily lost opportunity? The

Intel Core i9 10900K was considered its flagship product when it was first introduced in the 10th generation of Intel CPUs launched in 2020 and was sold as one of the most powerful CPUs to date. Now that the Intel Core i9 11900K has been identified as the 11th-generation flagship CPU, how do these two processors compare?

Read on to find out! Or, for a more in-depth discussion, see the 11900k and 5900X articles here.

The following is a comparison of Intel 11900K and 10900K specifications, and AMD Ryzen 9 5900X for reference.

Usually the most important factor that affects CPU performance in games is clock speed, and the lack of improvement in this regard for new processors seems puzzling at first. The basic clock speed of

Intel Core i9 10900K is 3.7 GHz Max Turbo, and the clock speed of TBMT 3.0 is 5.3 GHz, which is actually faster than Core i9 11900K in terms of basic clock. The basic clock speed of the latest chip is 3.5 GHz, an increase of 5.3GHZ, covering the sweet spot of gamers, but the lack of improvement here may surprise some people. Ultimately, 11900K relied on architectural enhancements (including in its cache) to improve performance.

In addition, although we haven't tested it yet, the Thermal Boost technology of the new CPU means that overclockers can extend it further, but it remains to be seen. With any CPU, you can enjoy a smooth gaming experience even if the pace is increased, and you can stay one step ahead of your opponents with fast response time.

Generally speaking, more cores mean better performance on tasks that rely on multi-core performance. These tasks are often mainly workstation tasks (3D rendering, video editing, music production, etc.). The latest games use more and more cores, but in general, its importance in games is still small compared to clock speed.

Both Intel CPUs are equipped with Hyper-Threading Technology. The cores are basically divided into threads, which provide twice the processing power like virtual cores, which means they can run multiple applications at the same time without causing performance or quality degradation.

Intel's 10th generation processors provide huge multi-core improvements over previous CPU series, and even the most basic 10th generation models are equipped with more threads than the more advanced 9th generation products. The Core i9 10900K has 10 cores and 20 threads, enough for gaming, which can be said to be more than you need, but it provides the necessary functions for dual-use systems for workstation tasks.

However, the 11th generation goes in the opposite direction, it has 2 cores less than the Core i9 10900K, only 8 runs and 16 threads. At first glance this may seem counterintuitive, but most games don't even use the full 10900K core count. Intel's strategy for upgrading the chips is to improve the overall architecture and pay more attention to the efficiency of graphics cards in game use and general single-core performance tasks, rather than workstation users.

Thus, 10900K is the preferred choice for workstation users (see our benchmarks below for testing), and having more threads than contemporary games currently require is possibly a good way to make that your computer's processor is future-proof Method to save you upgrade time in a few years.

One of the things that gets people so excited about the 11900K release is the debut of Intel's new Rocket Lake architecture, which comes after more than 5 years of stagnation in architecture development and enhancements. This is a slow and steady situation to win the game, if so,

Ryzen 5900X from AMD. The

Core i9 10900K uses the Comet Lake architecture, which is the 4th generation Skylake chip produced using the 14nm process. It provides improvements to the i9 9900K, has two additional cores and a faster clock speed, and supports the DDR42933 RAM storage type.

Although the previous 10900K version has a higher total L3 cache, since 11900K has fewer cores, the number of each core is basically the same (2MB). However, the advantage of the newer CPUs is that the L2 cache of each core has increased by 100% (512KB vs 256KB) and the L1 cache by 50% (96KB vs 64KB). In theory, due to the better minimum requirements, this should mean smoother games on the new generation of CPUs. The

Xe architecture should obviously provide up to 50% integrated graphics capabilities for users who do not use a separate dedicated graphics card.

compared to 10900K, 11900K has fewer cores and threads, which obviously puts it at a disadvantage in most workstation processes (although generally workstation processes are not always) more dependent multi-core performance.

AMD is the leader in workstation CPUs, and Intel has made a clear decision to focus on what they think can compete (games) and rely less on multi-core.

It can be seen from the benchmark test above that the i911900K is inferior to the 10900K and the AMD Ryzen 9 5900X in the Cinebench multi-core test. Compared to the 10900K, the efficiency is 4% lower (not much difference) and 28% more efficient than the AMD CPU. In our Adobe 4K and Blender tests, the rendering time is significantly slower, which is also the result. However, among processes that prioritize single-core performance, 11900K performs well.

Rumors about 11900K say that single core performance is 32% higher than 10900K, but based on our tests this seems very optimistic.

In some games we tested, the 11900K performance is actually worse than the previous CPU. It produces lower FPS in games like "Tomb Raider: Shadow" and CS: GO, and it produces lower FPS in Red Dead Redemption 2 More or less similar results, and in FarCry 5.

So what is the reason for this? The current thinking is that since the CPU has just been released, poor performance is the result of compatibility issues, and more BIOS and firmware updates will release the true potential of the chip.

For now, this is a wait-and-see game, but the first result is definitely disappointing!

At the time of writing, on the official release date of 11900K, the CPU certainly did not achieve Intel's goal: to provide stable single-core performance, giving priority to gamers rather than workstation users. Compared with

10900K, reducing the number of cores and other improvements in architecture should give you an advantage over the previous 10th generation CPU in this respect, but at the time of release, the performance of 11900K is not as good as that of its older representative. , And is about $50 higher for the suggested retail price.

Further BIOS and firmware updates may change this story, in this case, we will update this page accordingly. If you can wait without buying a CPU in the next few months, we recommend that you do so and see what happens next. This is especially true if you are an overclocker and want to push 11900K to the maximum Ghz possible.

However, if you want a dual-purpose workstation CPU, the decision is clear-10900K still prevails, regardless of the 11900K software update, due to its multi-core, so we will consider choosing this, or, better yet, It is one of the rival AMD processors.

Although we briefly mentioned some comparisons between Intel 11900K and its rival's flagship CPU AMD 5900X, for a more detailed comparison of these two processors, please refer to our other article on this topic.
