Best Review of Intel Core i9-11900K in 2021

Two minute review

It is disappointing that the Intel Core i9-11900K is not a big update. It, along with other 11th generation CPUs, seems a bit fresh to keep us waiting for something special to come. That is not to say that it is not a powerful desktop chip. It is and it can handle anything you want. That being said, it is not a product that makes Intel applicable in an increasingly competitive market


This is the system we used to test desktop CPU performance:

Price and availability

The Intel Core i9-11900K will be available on March 30, and the proposed retail price is $ 539 (39 390, AU about $ 710). That price makes this processor a direct replacement for the Intel Core i9-10900K and a competitor to the AMD Ryzen 9 5900X.




Intel Core i9-11900K Desktop Processor 8 Cores


Intel’s processors seem to have avoided the recent problems with graphics cards and AMD processors, so we’re not sure prices will be much higher.

However, as prices recover throughout the industry, the Intel Core i9-11900K AMD Raison 9 5900X or lower is not particularly visible when placed against the cheaper $ 449 (£ 419, AU $ 799). 7 5800X. Intel wins in some single thread applications and games. But when you want to spend close to a thousand rupees on your CPU and motherboard alone, you can’t imagine using your computer to play an overwatch.

For people who want to get some creative apps without coming to the HEDT (high-end desktop) platform, you may want to look elsewhere.

Chipset and Features

Like all other desktop platforms launched by Skylake in 2015, the Intel Core i9-11900K is based on the Rocket Lake-S architecture — it is built on a 14Nm process. However, unlike previous Comet Lake, Kaby Lake and Coffee Lake, this is not another iteration of Skylake.

Instead, Intel took the basic design of its 10nm Ice Lake processor, which is primarily found in laptops, and reported it back to the 14nm production process. Intel claims that this allows the clock speed to be higher than its 10 Nm processor, which is important for gaming. However, when combined with the dying Intel X graphics, the chip space for the CPU core is less, which means that the Intel Core i9-11900K has only 8 CPU cores compared to Intel’s 10-core design Less. Core i9-10900K.

That sounds bad, but this new Cypress Core core not only pushes the clock speed slightly – up to 5.3GHz on a single core – but also allows a significant 19% increase in instruction (IPC) performance per cycle.

However, it seems to be a big part of the upgrade that comes with Cypress Cove, resulting in higher energy consumption and with it higher temperatures.

During heavy workloads, especially the Blender, the Intel Core i9-11900K can reach 203W of power consumption by disabling the Asus ROG Maximus XIII Hero Multi-core upgrade that is enabled by default. By activating that option the power consumption pushed up to around 230W is much higher than using modern graphics cards.

When power consumption is so high, the temperature can also rise significantly. With all the partition settings, the Intel Core i9-11900K can reach 82 ° C, a significant leap above the 76 C that the Intel Core i9-10900K reaches under the same conditions. We are not using a lightweight CPU cooler – this comes with a 360mm AIO cooler so if you are thinking of grabbing this processor then consider getting a stronger cooler.

The Intel Core i9-11900K comes a few weeks after the Blue Team suspended its CPU overclocking responsibility. We usually do not cover overclocking in our reviews, as it still invalidates your warranty, but this processor consumes more power than ever and with more heat output, overclocking will be more difficult.

If you’re lucky enough to get a power-hungry graphics card like the RTX 3090 and you’re hoping to pair it with this processor, it’s a good idea to make sure you have a power supply that can handle it. Load.

However, not all is bad. With the Intel Core i9-11900K, Intel finally worked with PCIe 4.0 support, which means you can use the best SSDs on the market. Some Z490 tablets will even be able to use this functionality, but you will want to check your motherboard manufacturer’s website to see if it supports it.

Criteria and performance

Don’t get me wrong, Intel Core i9-11900K is a good processor. No matter what test we did on the small piece of silicone, it could be handled quickly and efficiently. Playing, creating content and even messing around on the desktop is quick, but it’s essentially the only experience you can get anywhere these days. We’re lucky enough to live in a time when any desktop processor is sufficient for what most people want. If so, the difference lies in how quickly things get done.

When you spend so much money on a processor, you will use it for a variety of things, and when it comes to creative workload, the Intel Core i9-11900K starts to lag seriously. Its main competitor is the AMD Raison 9 5900X.

In Blender, the 12-core AMD Raison 9 5900X is 58% faster than the Intel Core i9-11900K and costs only 2%. Also, on the Poojat Adobe Primer, the Core i9-11900K was 13% slower. This means that Intel Core i9-11900K is significantly slower than both 3D modeling and video editing.

This time around, the situation is a little better when Intel starts looking at the gaming benchmarks that are focused on its marketing. In the 3DMark Time Spy test, the Intel Core i9-11900K Ryzen 9 5900X managed 13,301 CPU points over 12,163, an increase of 9%.

However, when we look at real sports it is pretty much a wash. We tested Total War: Three Kingdoms and Metro Exodus, paired with 1080p lower settings and the Nvidia GeForce RTX 3090, pushing as much workload as possible to the processor. Also, in these tests, the Intel Core i9-11900K and Raison 9 5900X are very similar.

However, there is a significant difference from older processors. For example, the Intel Core i9-11900K was about 7% faster than the Intel Core i9-10900K during the entire war. It’s not enough to convince anyone to upgrade from 10900K, but it’s going in the right direction.

But even if it is, it is not. The loss of two 11900K cores means that the 2020 Intel Core i9-10900K will be significantly faster than the latest chip in heavily threaded applications such as Blender or Adobe Primer.

What’s even worse is that the Intel core i9-11900K is significantly slower than the AMD Ryzen 7 5800X, and the processor costs almost a hundred bucks less. AMD’s 8 primary champion in gaming and content creation overturned 11900K, beating the blue team by purely artificial single scales.

While AMD releases significantly faster processors year after year, the Intel Core i9-11900K shows how far behind Intel is and feels like a desperate attempt to keep the relevance while the company takes its real next step. We hope that Intel will bypass this generation and return with its 12th generation processors to offer something truly valuable. We hope we do not have to wait too long to see what it can offer.
