Pros And Cons

Comparison Table

Architectural Differences

1. Core Count: There’s a massive difference in the core count of both CPUs. The 14900K comes with a whopping 24 cores and 32 threads. Compared to that, the Ryzen 7 7800X3D only comes with 8 cores and 16 threads. 
2. Clock Speed: The performance cores of the i9 14900K usually clock at 3.2 GHz and go all the way to 6 GHz on the boost. The Ryzen 7 7800X3D, on the other hand, starts strong at 4.2 GHz but maxes out at the boost clock of 5 GHz. 
3. Process Node: Intel has not upgraded their process node in the last 4 generations. That’s why the Core i9 14900K is stuck with the 10 nm process node by TSMC. The Ryzen 7 7800X3D, in comparison, features the 5 nm process node. 
4. Memory: The Ryzen 7 7800X3D does not have support for the older DDR4 memory. The Core i9 14900K, on the other hand, appears to be backwards compatible with support for both DDR4 and DDR5 memory. 
5. L3 Cache:  The Ryzen 7 7800X3D has a massive 96 MB of L3 cache. That’s three times that of the Core i9 14900K’s 32 MB cache.

AMD’s latest Ryzen 7 7800X3D has made a name for itself among the gaming community for spectacular single-core performance. But how well does it stack up against Intel’s greatest offering which was primarily known for its gaming capabilities? Keep reading as we compare Core i9-14900K Vs Ryzen 7 7800X3D in a series of AAA games.

Gaming Benchmarks – 1080p

In order to make an elaborate and in-depth comparison between both of our CPUs, we have chosen to go with the following testing rig which was tailored to ensure that no CPU performance is left on the table. We will also be testing the games at 1080p resolution, as games tend to rely on GPU when we crank up the resolution. 

Gaming Rig

• OS: Windows 11
• GPU: GIGABYTE RTX 4090 Gaming OC 24G
• RAM: XPG Lancer RGB 32GB 7200MT/s DDR5
• SSD: XPG GAMMIX S70 BLADE 2TB NVMe
• CPU Cooler: Arctic Liquid Freezer II 420 – AIO Water Cooler
• PSU: ENERMAX REVOLUTION D.F. X 1050W

We have paired both CPUs with our top-of-the-line, Gigabyte RTX 4090. These benchmarks were designed to focus on the CPU performance, but if you wanna see the true potential of this beast, check out our review of GIGABYTE RTX 4090 Gaming OC 24G.

Cyberpunk 2077

• We start the benchmark with Core i9 14900K flexing its muscles by securing a lead in Cyberpunk 2077 with a margin of 5%. It was able to run the game at 140 fps, compared to the 132 fps of the Ryzen 7 7800X3D. 
• The 1% lows were also singing praises of the intel CPU, as it is 4% ahead there. It provided a solid 100 fps average in 1% lows. Not far behind was the Ryzen 7 7800X3D at 96 1% low fps. 

Call of Duty Warzone

• We seem to have witnessed a tie in Call of Duty Warzone, as no difference was observed in the average fps of both CPUs. Both CPUs were able to run the game at a very respectable average of 246 fps. 
• Despite similar fps, the game seemed to run smoother on Ryzen 7 7800X3D, as it provided 16% more 1% low fps. On average it provided 166 fps, whereas the Core i9 14900K maxed out at 141 fps. 

Microsoft Flight Simulator 

• Interesting turn of events in our gaming benchmark, as Ryzen 7 7800X3D, which was lagging behind previously, now secures a lead in Microsoft Flight Simulator by 11%. It provided 91 fps compared to the 81 fps of the Core i9 14900K. 
• Despite lagging in average fps, the intel CPU bags a lead in 1% lows, by performing 3% better. It yielded the 1% low of 65 fps, whereas the 7800X3D was at 63 fps. 

Remnant 2

• The Ryzen 7 7800X3D retains its lead in Remnant 2, as it provides 3% more fps in it. This time around, it was running the game at 142 fps, compared to the 138 fps by the Core i9 14900K. 
• Once again, despite coming short in average fps, the Core i9 14900K retains its lead in the 1% lows. The 1% lows observed on it were 117 fps, while the Ryzen 7 7800X3D was slightly behind at 116 fps. 

Forza Horizon 5

•  We witness the Core i9 14900K finally get its lead back by performing 2% better in Forza Horizon 5. It managed to run the game at a staggering 252 fps, whereas the AMD counterpart runs it at 246 fps. 
• The 1% lows were also on Intel’s side as it is 12% ahead there. This time it was able to yield the 1% low of 191 fps, compared to the 169 fps of the Ryzen 7 7800X3D.

Resident Evil 4

• Resident Evil 4 seemed to run better on the AMD CPU, as it is 1.59% ahead there providing an average of 190 fps. The Core i9 14900K, on the other hand, provided 187 fps. 
• The 1% lows had a much more prominent degree of separation at around 7%, that too in favor of 14900K which was lagging previously. This time it provided the 1% low of 151 fps compared to the 140 fps by 

Red Dead Redemption 2

• We close the benchmark with Ryzen 7 7800X3D retaining its lead by a 6% margin in Red Dead Redemption 2. This time, it provided 193 fps as a response to 14900K’s 182 fps average. 
• The 1% lows could not save intel either, as Ryzen 7 7800X3D is 10% ahead there, with an average of 148 1% low fps. The Core i9 14900K, at the same time, is at 133 fps. 

Overall Gaming Performance

Both of these CPUs were fairly close during our gaming benchmarks. Some games ran better on the 14900K, while others ran better on the 7800X3D. However, on average, the Ryzen 7 7800X3D did outperform the Core i9 14900K by a margin of 1.7% in terms of average fps. The average 1% lows on both CPUs were exactly the same. 

Editor`s Note

From what we have seen in the gaming benchmarks, AMD seems to have knocked out of the park with the 7800X3D, as it costs less and performs better than the 14900K. However, gaming only relies on the single-core performance of a CPU. For a pure flagship comparison check out Core i9-14900k Vs Ryzen 9 7950X.

Thermal Efficiency

When it comes to thermal efficiency, the Ryzen 7 7800X3D runs approximately 4.3% cooler in games compared to the Core i9 14900K. The TSMC’s 10 nm chip is, after all, harder to cool. Therefore, if temperatures are a concerning factor for you, then you should consider the 7800X3D since it is more thermal efficient out of the two.

Price And Value

Both of these CPUs were launched with a very different price tag for a different consumer. The Ryzzen 7 7800X3D is a mid-ranger processor from its series, whereas the 14900K is the best and most expensive CPU offered by Intel as of now. That explains the 27% difference in the price of both of these chips. 

What We Recommend

Ryzen 7 7800X3D: In our opinion, the Ryzen 7 7800X3D is an easier recommendation out of the two CPUs. It costs less than the 14900K while performing better in games and running cooler. It is also on AMD’s latest socket, so the upgradability path is better if you go with this CPU.

Core i9 14900K: If you want an overall jack of all trades, and you don’t mind spending extra bucks for it, then the Core i9 14900K is recommended for you. It has splendid gaming performance as observed in the benchmarks. It has three times as many cores as the 7800X3D and lastly, it can support both DDR4 and DDR5 memory. 

After personally testing these CPUs, we can vouch that both these CPUs are very capable of gaming. You can not go wrong with either of them. However, they both have their own specific use cases and target audiences.
