CPU Intel I9 10900x vs Ryzen 9 3900X. Comparison + tests in games!

Hello, everyone! In this video, we’re going to compare two top processors – the Intel i9 10900X and the AMD Ryzen 9 3900X – and also test their performance in modern games.

General Characteristics

The Intel Core X-Series processors are the most powerful processors in the series. They cope with any resource-intensive tasks and workloads, such as creating content or broadcasting the passage of modern games. This solution will provide the user with all the necessary features for productive work.

The i9 10900X has the latest Cascade Lake-X architecture and is compatible with the LGA-2066 socket. The Ryzen 7 3700X with innovative Zen 2 architecture also offers great features and is not inferior to the competitor in terms of performance. It is still compatible with the current AM4 socket, so it will work in motherboards released for the previous generations of Ryzen. In terms of energy consumption, the Intel is much more voracious than the opponent – it consumes 165 watts versus 105 watts of the Ryzen processor.


Both models have impressive features.

The i9 10900X has ten cores and twice as many threads. The Ryzen processor has as many as 12 cores and 24 threads. The volume of level 3 cache in the 3900X is 44 MB larger and amounts to 64 MB, compared to 20 MB for the model from Intel. The AMD processor boasts a highly efficient 7 nm process. Thanks to this, the processor power increases, and its power consumption becomes smaller. The process value of the i9 10900X is 14 nm. The maximum core frequency, again, is slightly higher for Ryzen – 4.6 GHz versus 4.5 GHz for the Intel. In this case, both processors can be unlocked to be even more powerful.

The developers see the i9 10900X as a model for resource-intensive creative or work purposes. As I already said, this processor is supported by 10 AVX-512 cores with improved Turbo Boost Max 3.0 technology. This helps the most important workloads to be sent sent to the four fastest processor cores. Thanks to the new advanced technologies, the user gets maximum performance, excellent speed of the storage subsystem, as well as memory.

The unlocked multiplier also deserves to be mentioned. It provide the Intel’s model with an additional margin of performance. The user can use overclocking for each core separately. Also, in order to increase stability, you can control the AVX coefficient, and in extreme scenarios, you can adjust the VccU voltage. Using tools from Intel, such as Performance Maximizer, Extreme Tuning Utility and Extreme Memory Profile, you get all the features to achieve optimal performance.

The Ryzen 9 3900X specifications are also pleasantly surprising. In the consumer segment, this processor stands out from the rest because of its parameters. Thanks to the implementation of the chipset design by the developers, this stone received a huge cache and an increased number of cores. The Ryzen 9 3900X is an excellent proof that AMD chose the right direction. It’s going to be extremely difficult for competitors to catch up with this processor in terms of basic characteristics.

On the other hand, most modern games do not use more than 8 cores, which means that in terms of gaming, the Ryzen processor most likely will not be able to reach its full potential.

Well, let’s have some game tests to see if it’s all true.

Gaming Test

Our processors are going to work in conjunction with the RTX 2080 Ti graphics card. The Asus Prime X299-A II and GIGABYTE X570 AORUS PRO motherboards were used for for the Intel and the AMD respectively. To fully evaluate the performance of these models, the testing was carried out at the maximum graphics settings in Full HD resolution.

Kingdom Come: Deliverance is a fun, single-player, open-world role-playing game. The project was developed by the Czech studio Warhorse Studios, and released in 2018 by Deep Silver. The game focuses on historical authenticity; it reproduces the atmosphere of medieval Czechia in detail starting from clothing and weapons to architecture and the social structure of the country.

As you can see, the twelve-core Ryzen is only 1% inferior to the model from Intel. The difference in the minimum FPS is slightly larger – it is 8%.

By the way, don’t forget that you can find out all the current prices for these processors by clicking on the links that I specifically left for you in the description below.

Metro Exodus or Metro Exodus is a shooter-style computer game developed by 4A Games and released by Deep Silver in February 2019. The third part of the Metro game series continues the story described in the books of the popular Russian writer Dmitry Glukhovsky.

As for the testing, both models show excellent results here – there are no serious drawdowns, bit there is a slight advantage of the processor from Intel. This time, the average FPS difference is 4%.

In May 2018, Electronic Arts released the 15th part of the eponymous series – Battlefield V. In this first-person shooter, several stories are told about the Second World War, the player will be in the role of different military branches of the army, as well as nationalities.

The numbers are almost the same, this time the 3900X overtook the Intel processor by 1%.

Red Dead Redemption 2 is a game from Rockstar Games in the genre of shooter and action-adventure, with a well-developed open world, released for personal computers in 2019. It is the third part in the game series Red Dead, as well as a prequel to the 2010 Red Dead Redemption. The game setting is saturated with the western atmosphere. Of course, the action takes place in the Wild West in 1899 on the territory of several US states. The storyline is built around the adventures of a gang commanded by Dutch van der Linde.

Both models provided smooth gameplay again. As for the average FPS, the advantage of 5% goes to the i9 10900X.

In the fall of 2018, Ubisoft studio released another Assassin’s Creed, this time it was called “Odyssey”. The player will be in Ancient Greece in the midst of the Peloponnesian war and try on the role of a descendant of the legendary Spartan king Leonid.

In terms of gaming performance, there is complete parity. Both models showed the same average FPS which is 108 frames per second.


So let’s summarize. Today we compared the Intel i9 10900X and the AMD Ryzen 9 3900X. As it was expected, these processors showed the highest results in the gaming tests. The models demonstrated almost the same average FPS, with a minimal margin towards the processor from Intel. Althoug you might not notice that in real gaming conditions.

On the other hand, the 3900X copes with loads of almost any kind. In addition, the flagship AMD performs work tasks faster than the ten-core i9 10900X, which costs significantly more.

If you are a fan of Intel and want to have one of the fastest gaming processors which also effectively copes with work tasks, then the i9 10900X is a great option for you. If you don’t want to overpay and you need a universal processor not only for games, but primarily for work, which would also perform resource-intensive tasks and creating content, then the Ryzen 9 3900X is your choice.
