We are testing the performance difference between RTX 4090 i9 13900k vs RX 7900xtx Ryzen 9 7950x to see which combo is better for gaming.
There is a saying that you will get the best performance when using AMD-specific systems or Intel + Nvidia system combinations. And maybe that is true in some cases, although in recent years, with the advancements of chip technology, it doesn’t matter what combination you use.
I won’t say there won’t be a difference at all. There will be, but that will be very negligible as both Nvidia and Radeon are very competitive in manufacturing GPUs. No brand wants to lose out on sales, which is why all the GPUs are tailored to work with all the supported CPUs despite being on different brands.
And recently, with the entry of Intel Arc Graphics cards in the market, the competition between these brands is much more intense. But who cares? We are testing out two flagship systems that we have in our office.
We paired each of them with the flagship products of Intel, AMD, Nvidia and Radeon, and we bring you the RTX 4090 i9 13900K vs RX 7900XTX Ryzen 9 7950X to answer the question once and for all; which combo to buy Nvidia + Intel or AMD + Radeon in 2023.
So without further delay, let’s check out the RTX 4090 i9 13900K vs RX 7900XTX Ryzen 9 7950X Gaming Performance.

AMD CPU and GPU Combo vs Intel CPU and Nvidia GPU Combo- Final verdict
The above chart list shows that with the pairing of Nvidia GPU with the Intel CPU, the performance is much ahead of the combination of AMD GPU and CPU. In almost every game, the Nvidia RTX 4090 GPU and Intel Core i9 13900K CPU has provided at least 20+ fps only, except Cyberpunk 2077, where the difference was a little less than the above-mentioned 20FPS.
These CPUs never thermal throttled during the tests and provided a lag-free and a very smooth experience. The GPU temperature which is listed is the stable temperature while gaming mode. In this case, Nvidia RTX 4090 remains cooler than RX 7900XTX at an average of approximately 10℃. Also, these GPUs never reached their thermal throttling point and performed flawlessly.
To sum up, if you have the budget, we advise you to upgrade your system by pairing the RTX 4090 GPU with an Intel 13900K CPU. And if you are on a bit budget lower than that or if that extra 20+ fps doesn’t bother you, go for the AMD Ryzen 9 7950X CPU with Radeon RX 7900XTX GPU.
So this was all about RTX 4090 i9 13900k vs RX 7900xtx Ryzen 9 7950x Gaming Performance benchmarks. If you think we have missed anything, let us know in the comments below.
