The greatness of Ryzen CPUs
Ryzen CPUs especially the 5000 series and even the 3000 series chips didn’t spare Intel and proved that they are worthier than most Intel chips when it comes to purely gaming purposes, even though Intel was the one to hold that title for a long time.
It’s not that Intel’s latest-gen processors are bad but they are inferior to the Ryzen 5000 series due to lack of significant improvement as a result of not changing the process technology where AMD changed the game since the release of Ryzen 3000 series processors.
Benchmarks have shown that AMD is much ahead of the 10th gen Intel processors with the latest Ryzen 5000 processors and does all the tasks faster for less price. This makes them the perfect option to build a PC whether for only gaming or for running CPU-dependent applications.
Nvidia graphics cards with AMD processors
When we talk about using Ryzen with Nvidia graphics cards, it’s not necessarily that you have to use only the latest-gen CPUs with the latest-gen GPUs. While I don’t recommend buying a 1st gen Ryzen or Pascal GPU right now, you can still get them for your PC if you can’t afford the new ones.
It’s a forever question of whether an Nvidia GPU is good to use with an AMD processor or only Intel. While it can be said that an AMD processor will be good with an AMD graphics card right now due to the introduction of Smart Access Memory, the technology will soon be available with the Nvidia GPUs too.
So, there is currently no reason why you should care about using and AMD CPU with an Nvidia GPU, or an Intel CPU with AMD GPU except if you don’t like the inferior AMD GPU drivers.
Nvidia RTX 20 series GPUs
RTX 20 series graphics cards based on the Turing architecture are the first ones to bring Ray-Tracing technology that makes dynamic real-time shadow and lighting effects. They are still good even after the RTX 30 series release and can be used with Ryzen CPUs for 1080p gaming or higher. Various benchmarks have shown that they are completely fine with AMD Ryzen 2nd and 3rd gen CPUs. As the GTX 10 series have grown older, I simply recommend skipping it for either the RTX 20 or 30 series GPUs for building a gaming PC.
Nvidia RTX 30 series GPUs
RTX 30 series graphics cards are way ahead of every previous Nvidia series and beat the RTX 20 GPUs like they are nothing. An RTX 3070 is almost equivalent to 3 times more expensive RTX 2080 Ti and the same goes for other 30 series graphics cards.
With Ryzen 5000 CPUs already released, there is no better option than to use an RTX 30 series GPU. The only problem is the availability of both of these which is believed to last Q1 2021. But if they are available in your region, then I would recommend going with the following combos for best performance.
Best Ryzen Nvidia combos
Ryzen 5 3600 + RTX 2070
Ryzen 5 3600 before the 5600X was the best gaming CPU for its price and is still considered among the top 5 for its price. It features 6 cores and 12 threads that make it a perfect fit for gaming and multi-tasking. With the new 7nm process technology and Zen 2 architecture, it is capable of maxing out games at 1440p resolution with an RTX 2070. This combination should cost you somewhere $600-$700.
Ryzen 5600X + RTX 3060 Ti
Ryzen 5600X is the successor of 3600 having the same core and thread count but now with increased max boost clock. It is significantly faster in single-core/multi-core performance as it features a single CCX for immediate access to Cache memory and annihilates even the best of Intel processors in gaming. Combined with the best $400 graphics card RTX 3060 Ti, you will achieve much more than the previous combo at 1440p resolution.
Ryzen 5800X + RTX 3080
For 4K gaming, RTX 3080 is the best value card from Nvidia and provides decent performance even with Ray Tracing On. This thing can max out games at 4K resolution with 60+ fps and that’s why you will need a high-core count CPU to avoid any type of bottleneck at 4K resolution. Ideally, the Ryzen 5600X will be ok but you will see up to 5% lower frame rates as compared to 5800X which is an 8 core 16 thread processor((https://www.youtube.com/watch?v=FV2oZMUkRFg)).
Ryzen 5900X + RTX 3090
Ryzen 5900X is a massive upgrade over the Ryzen 5600X and 5800X and features 12 cores/24 threads that is overkill for gaming. Combine it with RTX 3090 that consists of 10496 Cuda Cores and you have an unbeatable gaming rig that will last a decade(opinion). This combination can kill games at 4K resolution and can play most games at 8K resolution easily with good frame rates.
Conclusion
There are a lot of possible combinations you can make out of Ryzen processors and Nvidia GPUs and there is no problem if you go with something like a Ryzen 2600X with GTX 1080 or Ryzen 5600X with an RTX 2080/3080. The AMD-Nvidia combination works very well and shouldn’t be taken as inferior to Intel-Nvidia combos.
