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 NodeIntel 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 CacheThe 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

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.

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

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

ProcessorLaunch MSRPCurrent Price
Core i9 14900K💲589💲589
Ryzen 7 7800X3D💲449💲449

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. 

Frequently Asked Questions

Which one is better recommended for a warmer climate?

Our observation states that the Core i9 14900K ran approximately 4.38% hotter than the Ryzen 7 7800X3D. So if you dwell in a warm climate zone, you should consider the latter.

Which one has a better upgradability path?

The Ryzen 7 7800X3D has a better upgradability path since it is the first series to utilise AMD’s new socket. Intel, on the other hand, was using the same socket for 3 years, so it will be discarded this year.

Can you use older DDR4 memory on Ryzen 7 7800X3D?

AMD dropped the support for DDR4 memory in their latest 7000 series of CPUs, which also includes the Ryzen 7 7800X3D. This means your only option is to use DDR5 memory with it.
