AMD Ryzen 9 3900X vs. Ryzen 7 3700X vs. Intel Core i9-9900K: Which is the best gaming CPU?

By Koh Wanzi - 25 Dec 2019

Conclusion

A great third outing from AMD

AMD has pretty much knocked it out of the park with its third-generation Ryzen products. The Ryzen 9 3900X clearly delivers excellent multi-threaded performance and very competitive gaming results, so it's a clear choice for both gamers and content creators. If you're a Twitch streamer that wants to consistently deliver a good quality 60fps stream, the Ryzen 9 3900X is shaping up to be a great choice.

However, it's the Ryzen 7 3700X that is really the standout performer. At just S$498, it consistently leads the Core i9-9900K in multi-threaded workloads. It's not that far behind in terms of gaming performance either, and it's possible to make the argument that the trade-off is pretty worth it. At the moment, the Core i9-9900K is retailing for a whopping S$758 on Lazada (that's the cheapest listing I could find on the site), a hefty premium that is probably not justified by the 10 percent or so lead that it has over the Ryzen 7 3700X. 

The Core i9-9900K is still the king of raw gaming performance but the new Ryzen 7 3700X and Ryzen 3900X offer unparalleled value and bang for your buck.

Similarly, the Ryzen 9 3900X costs S$798, only slightly more than the Core i9-9900K. That's quite some insane value right there, for only slightly lesser gaming performance and a huge lead in content creation tasks.

While it seems like the Core i9-9900K may still be king if all you care about is raw gaming performance, that's often not the case today. Plenty of people want to be able to stream stuff on Twitch or render video, in addition to playing games. For folks like these, the new Ryzen 7 3700X and Ryzen 9 3900X step up to the plate admirably. I can't say that the new Ryzen 3000 chips dethrone the Core i9-9900K as the best gaming CPU, but I can say that they are the best and most value-for-money chips when it comes to both gaming and content creation, which is exactly what AMD was shooting for. 

As processors with over eight cores start to become the norm, multi-threaded performance, and not just in-game frame rates, will start to become an increasingly important metric, and it's in this area that AMD absolutely shines.
