Both of the highest-end processors from AMD and Intel work towards the same goals, but they try to achieve them through different techniques. This Core i9-13900k vs Ryzen 9 7950x comparison will put a face to the difference between the two, and crown a definitive victor in terms of gaming performance.

Key Takeaways

• The core i9-13900k provides 24 cores, and Ryzen 9 7950x 16 has physical cores. A greater number of cores helps in delivering better performance.
• The turbo clock of the Intel core i9-13900k is up to 5.8 GHz i.e., greater than the 5.7 GHz max clock of the Ryzen 9 7950x.
• The Ryzen 9 7950x only supports DDR5 memory while the Intel core i9-13900K supports DDR4 and DDR5it better for users with a lower budget to set up their PCs.
• The gaming performance of the Intel core i9-13900K was better than the R9 7950x in almost all the games. Thus, core i9-13900K would be a better option for gamers.

Gaming Benchmarks

9 games were tested in the first series at a high resolution of 1440p. These benchmarks were obtained using our measured test bench, the specifications of which are mentioned below:

• GPU: Nvidia RTX 4090
• OS – Windows 11 
  
• CPU Cooler – Cooler Master MasterLiquid Lite ML240L RGB
• SSD – XPG Gammix S70 Blade 2TB NVMe
• Power Supply – ENERMAX REVOLUTION D.F. X 1050W

Counter-Strike: Global Offensive

• Our test showed that the Ryzen 9 had an average framerate of around 688 FPS, whereas the Core i9 was much further ahead with an average framerate of 800 FPS. The difference in framerate is not noticeable when it is so high already on both processors, but in such a CPU-bound game, this draws a good representation of the overall gaming performance of these processors.
• The 1% lows hit around the same number for both processors, with the Ryzen 9 getting lows of 280 FPS in our testing, while the Core i9 had minimum framerates of 288 FPS.

Cyberpunk 2077

• The average framerates still showed quite a bit of difference in our test of Cyberpunk, a relatively GPU-intensive game. The Core i9 had an average framerate of around 144 FPS, while the Ryzen brought the framerate down to 130 FPS. Though still relatively unnoticeable, the difference between these processors is relatively large for a CPU swap.
• The 1% lows were the same on both systems, 95 FPS.

Diablo II Resurrected

• The average framerates with both processors differed quite a bit in our test of Diablo II. The Core i9 had an average framerate of 210 FPS, which was noticeably more responsive than the 185 FPS average of the Ryzen 9 7950x.
• Surprisingly, our tests showed the 1% lows of the Ryzen to be better at 130 FPS vs 106 FPS on the Core i9-13900k, which is more of a noticeable metric to find a difference in, considering the average framerates are super high already.

Fortnite

• The rather large differences in average framerates continue with our test of Fortnite. The average of the i9 13900K reached around 227 FPS, whereas the Ryzen 9 had a performance of around 199 FPS. This difference can be very noticeable to e-sports players who enjoy this game.
• The 1% lows had a large deviance as well in our test. The i9 had minimum framerates of around 142 FPS, whereas the Ryzen 9 had minimums of around 129 FPS.

God Of War

• Our test of God Of War had the same disappointing performance from the Ryzen 9 with an average framerate of 111 FPS, whereas the Core i9-13900k rose above it with an average of around 129 FPS.
• The 1% lows were even more drastic in our test. The i9 had lows of 106 FPS, whereas the Ryzen 9 dipped all the way down to 90 FPS.

Marvel’s Spider-Man

• Swinging through the streets of New York in Marvel’s Spiderman gave us the closest performance gap between these two chips. The i9 had an average framerate of 127 FSP, whereas the Ryzen 9 was slightly slower with an average of 122 FPS.
• The 1% lows weren’t terribly different as well in our testing. The i9-13900k got down to minimums of around 81 FPS in our testing, whereas the Ryzen had a minimum framerate closer to 77 FPS.

Microsoft Flight Simulator 2020

• In our test of Flight Sim 2020, the i9-13900k came out ahead with an average framerate of 122 FPS, whereas the Ryzen 9 had an average framerate of around 111 FPS. 
• The 1% lows were pretty close in this game, with the Ryzen 9 7950X getting around 86 FPS, while the i9 lagged behind with lows of around 81 FPS.

Red Dead Redemption 2

• The average framerate was greater on the i9-13900k in our testing of RDR2. The Intel processor managed an average framerate of 130 FPS, while the Ryzen 9 had an average of around 120 FPS.
• The 1% lows had a similar level of difference, which the Ryzen 9 7950X going down to around 89 FPS, while the i9-13900k had a minimum framerate closer to around 98 FPS.

The Witcher 3: Wild Hunt

• Finally, the Witcher 3: Wild Hunt also ran better on the i9, marking its final victory for this comparison. The Intel chip gave a performance of around 163 FPS on average, significantly beating out the 148 FPS average of the Ryzen 9.
• 1% lows were also noticeably smoother on the i9, hovering around 122 FPS, while the Ryzen 9 had lows of around 110 FPS in our testing.

Overall Gaming Performance

Now that we have some knowledge of the performance of the Core i9-13900K vs Ryzen 9 7950x, this part of the comparison will take a step back to look at the average performance of either processor. 

Framerate

• The i9 had around a 13.5% increase in average framerate compared to the Ryzen 9, which is very significant. Our testing showed the i9-13900K to give an average framerate around 223 FPS in the games we tested, whereas the Ryzen 9 7950x hovered around 201 FPS.
• 1% lows were not as drastically different in our tests, but there was a difference. The i9 had lows of around 124 FPS, whereas the Ryzen 9 had lows of around 120 FPS.

Temperature

• The higher performance of the Intel processor also came at the cost of more temperature, with the processor peaking at around 67ºC on average in our testing, while the Ryzen had a peak temperature of around 63ºC on average.
• There are a multitude of factors that can affect the temperatures of your processors, so your exact result may vary from us.

Price And Availability

• Being some of the most powerful processors on the planet, neither of the CPUs in this comparison comes cheap. The 13900K retails for around $569, while the Ryzen comes in a bit cheaper at around $552 on average.
• These processors should be available all around the world.

Core i9-13900K Vs. AMD Ryzen 9 7950X: What We Recommend

• i9-13900K: High-end processor with extra cores for excellent all-around performance and gaming.
• Ryzen 9 7950x: Slightly cheaper but requires a new platform and RAM standard, increasing overall cost. Requires a new build.
• Compatibility: 12th gen Intel processors allow for a drop-in upgrade, while Ryzen 9 7950x necessitates a new build.
• Performance: Both processors bottlenecked an RTX 4090 in 1080p tests, but with a more modest GPU, they offer similar performance.
• Winner: i9-13900K provides better performance for a similar price, making it the preferred choice in the comparison.
