AMD Ryzen 5900X 2-AMD Ryzen 9 5900x is another outstanding gaming CPU built-on Zen 3 architecture. With a huge IPC bost up for exceptional single-core performance and improved core-to-core latency, this is one of the most competitively priced mainstream gaming CPUs.

In AMD Ryzen Zen 3 series, it is the second most powerful gaming CPU after 5950x. The only advantage it gets over its big brother is the price. CCD layout of ZEN 3 architecture has significantly helped to boost gaming performance. In Zen 3 architecture, they have centralized 8 cores-CCX with a single CCD.

It means instead of two CCX per CCD; Zen 3 architecture features one CCX per CCD. This will help in reducing core-to-core latency, and each CCX will have complete access to the L3 32MB cache for a total of 64 MB. Moreover, AMD engineers claim to provide a 19% boost up in IPC (instruction per cycle), which helps it stand out as one of the most powerful gaming and multi-tasking CPUs.

Featuring an AM4 platform, the Ryzen 9 5900 is compatible with starting from X470 and B540 or above. However, all of you having X470 and B450 motherboards will be able to install them on this CPU after a BIOS update expected in 2021.

The processor has 12 cores and 24 threads, a base clock frequency of 3.7 GHz, and a boost clock frequency of 4.8 GHz. It is the ultimate choice for serious gamers who want a powerful gaming CPU under $900. Having a TDP rating of 105W, same as 5950x, it manages heat and power consumption very well.

As AMD is only concerned with a boost in performance, it may achieve the highest temperature up to 98 degrees celsius. However, in many independent tests, it reaches a maximum of 84 degrees celsius when paired with a cooler. Remember, the CPU doesn’t come with a built-in cooler, and you need to pair it with an external cooler.

Pros
