AMD Ryzen 9 3900X Review | A Behemoth of a CPU

There’s no doubt that since Ryzen 3000 was launched that AMD has been taking over the gaming and workstation market with their standard Ryzen chips and threadripper. In this review, I’m going to be taking a look at one of the top tier Ryzen CPUs, the AMD Ryzen 9 3900X! 

Big thanks to AMD for sending this out for review!

What’s in the Box?

Included in the box with the Ryzen 9 3900X is AMD’s Wraith Prism RGB that is a pretty decent cooler but not really recommended if you plan on overclocking. Also included in the box is obviously the CPU itself.

Features

The release of AMD’s 3rd Gen Ryzen brought a lot of new tech to the table including their new 7nm Zen 2 architecture giving AMD the upperhand in both single and multithreaded applications compared to the competition from Intel.

The biggest and most important development compared to previous gen Ryzen is the increase in IPC (Instructions per Clock). AMD claims to have been able to increase 3rd Gen Ryzen’s IPC by 15% giving it a massive performance boost in single threaded applications compared to the last generation of Ryzen CPUs.

Another big milestone for AMD is bringing 7nm processors to the consumers hands with 3rd Gen Ryzen, By using 7nm Cores inside the ‘Chiplets’ AMD was able to cram a massive amount of L2 and L3 cache into these new CPUs. In the case of the 3900X it has a whopping 64MB of L3 Cache and 6MB of L2 cache combined to make 70MB of AMD’s ‘GameCache’. This new ‘GameCache’ is a massive leap in the gaming side of tech and brings much higher performance to gamers seeking higher FPS and more performance in both 1080p Gaming and 1440p Gaming.

Chipset

And of course a new generation of CPUs brings a new chipset. 3rd Gen Ryzen was built to be used on the X570 platform but is also compatible with previous chipsets like X470/B450(BIOS Update required on previous gen motherboards to support 3rd gen).

But, by using X570 you are able to unlock more performance by using the new generation of PCIe, PCIe Gen 4.0. PCIe Gen 4.0 gives users quite a few benefits but one of the biggest performance leaps is in NVMe SSDs.

PCIe 4.0 unlocks a higher amount of throughput capable by the PCIe lanes giving you the ability to use faster SSDs and see higher speeds than ever before!

I haven’t been able to test any PCIe Gen 4.0 SSDs yet but I have some coming soon so keep an eye out!

Performance

Even though the 3900X is no longer the most powerful consumer CPU that AMD offers, the 3950X has taken this spot, it is still one hell of a beast of a CPU.

Conclusion

If you’re looking for a super powerful CPU for both gaming and workstation tasks, the AMD Ryzen 9 3900X is definitely the way to go. With it’s 12 Cores and 24 Threads it is a behemoth of a CPU capable of practically anything you throw at it. Plus you get the added benefit of being future proof with PCIe Gen 4.0.

Do note that some tasks do favor Intel CPUs but for the little performance gain that you would get, Although, I don’t think that it is worth the extra cost.

Buy one from Amazon Australia or Amazon.com!
