The Intel Core i5-12400F is a six-core, 12-thread processor based on the Rocket Lake architecture. It has a base clock speed of 2.9 GHz and a boost clock speed of up to 4.4 GHz. It also has 12 MB of Intel Smart Cache and supports DDR4 memory.
The AMD Ryzen 7 5800X is an eight-core, 16-thread processor based on the Zen 3 architecture. It has a base clock speed of 3.8 GHz and a boost clock speed of up to 4.7 GHz. It also has 32 MB of L3 cache and supports DDR4 memory.
In terms of performance, the Ryzen 7 5800X is generally considered to be significantly faster than the Core i5-12400F, especially in multi-threaded workloads. The Ryzen 7 5800X has a higher core count and thread count, as well as a larger L3 cache, which allows it to handle more tasks concurrently and provides a significant performance boost in heavily multi-threaded tasks such as video editing, 3D rendering, and content creation. The Core i5-12400F may still be a good choice for some lighter workloads, but it is generally not as well-suited to heavily multi-threaded tasks.
Overall, the Ryzen 7 5800X is a more powerful processor that is better suited to demanding workloads, while the Core i5-12400F is a more budget-friendly option that may be suitable for some lighter workloads.

Cache
The Intel Core i5-12400F has 12 MB of Intel Smart Cache, while the AMD Ryzen 7 5800X has 32 MB of L3 cache.
The cache is a type of memory that is used to store frequently accessed data, allowing the processor to access it more quickly. Larger cache sizes can help to improve the performance of the processor, especially in tasks that make heavy use of the cache.
In general, the Ryzen 7 5800X’s larger L3 cache size may provide a slight performance advantage in heavily multi-threaded tasks that make use of the cache, such as video editing, 3D rendering, and content creation. However, the overall performance difference between the two processors is likely to be more influenced by other factors such as clock speeds and core count.
Overall, both the Core i5-12400F and the Ryzen 7 5800X are high-end processors that offer excellent performance for demanding workloads. The Ryzen 7 5800X may have a slight performance advantage due to its larger L3 cache, but the Core i5-12400F may still be a good choice for some users, especially if they don’t need the additional cores and threads and want to save money on processor.
Which one is good for gaming?
Both the Intel Core i5-12400F and the AMD Ryzen 7 5800X are powerful processors that can handle gaming quite well. However, the Ryzen 7 5800X may offer a slight advantage in terms of overall performance and may be the better choice for gaming.
The additional cores and threads of the Ryzen 7 5800X may allow it to perform better in multitasking and CPU-intensive tasks, such as gaming, compared to the Core i5-12400F.
However, the actual performance difference between the two processors will depend on the specific game and other system components, such as the graphics card and memory.
It’s worth noting that the Ryzen 7 5800X also has a higher power consumption and may require a more robust power supply unit (PSU) compared to the Core i5-12400F.
Here is a great video comparing real-time gaming benchmarks of both CPUs.
Both the CPUs come with no integrated GPU. So, you will have to get an external graphics card in order to play games.
Which one is good for productivity?
Both the Intel Core i5-12400F and the AMD Ryzen 7 5800X are powerful processors that can handle productivity tasks well. However, the Ryzen 7 5800X will offer a slight advantage in terms of overall performance and may be the better choice for productivity.
In general, the additional cores and threads of the Ryzen 7 5800X may allow it to perform better in multitasking and CPU-intensive tasks, such as video editing and 3D rendering, compared to the Core i5-12400F. However, the actual performance difference between the two processors will depend on the specific workload and other system components, such as the graphics card and memory.
Again, there will be a slight difference in the performance. Overall, these both will provide you with the same results.
Price
Which one to buy: Intel Core i5 12400F vs AMD Ryzen 7 5800X?
Both of them are offering almost similar performances. However, the 12400F has a little better single-core performance. But, that will not help you a lot in any specific area. So, in my opinion, 5800X will be a better choice. Now, you will have to look at your budget. If you have to pay a huge amount for 5800X, there is no point in not buying the 12400F.
If gaming is your priority, 12400F will be capable of giving almost similar results to the 5800X. But, for productivity, you can see some advantages with the 5800X.
