It’s the clash of the titans: the 14900K vs 7950X3D! Intel is once again refreshing its CPU line-up, although the changes aren’t too significant compared to the previous gen. To answer the age-old question “AMD or Intel?”, we are pitting the pinnacle of each against one another, the Intel Core i9-14900K vs AMD Ryzen 9 7950X3D.

The Intel 14th gen release date, and the Intel Core i9-14900K release date along with it, has now passed by. Before deciding on purchasing the 14th Gen Intel CPU, it’s advisable to first understand the differences between these processors. Both the 7950X3D and the 14900K are high-priced options at the top of the range, making it crucial to educate yourself about their comparative features. Not only that, but you require different hardware to install them both into your system. Despite rumors of a socket change this year, the LGA 1700 socket remains, consistent with the past two generations.

Intel have confirmed the i9-14900K specs as you can see above. It does have the potential to be a great Intel CPU, however, after looking at the numbers. But how does Intel’s best CPU, the 14900K, compare against the 7950X3D?

As we know, AMD led the multi-core performance sector for many years, whereas Intel prevailed in single-core performance. It seems, however, that over the past few years, we have seen a slight shift. On paper, the 14900K takes the cake for the more powerful processor, it has more cores, with 1/3 of those cores able to boost higher than the max boost on the 7950X3D.

Intel has proven itself with the 12900K, and the 13900K that Intel can handle both multi-core performance, and have single, per-core performance in the bag too. But AMD isn’t going to take that lying down. The X3D component of the 7950X3D allows some games to take advantage of the CPU’s super fast stacked 3D v-cache. This means the AMD CPU will be able to gain an impressive edge in some games. But will it be enough to beat the 14900K?

14900K vs 7950X3D price

Since the Intel Core i9-14900K has been listed on Amazon, the pricing for it has been confirmed. As below:

• Intel Core i9-14900K: $599 US
• AMD Ryzen 9 7950X: $699 (launch) $599 (now)

As you can see, the 7950X price has dropped from its launch price to match the i9-14900K. Still, we believe that the 14900K is a clear winner here based on the specs and likely performance.

14900K vs 7950X3D performance

As our CPU specialist Mr Jack Howarth found in his benchmarking of the new processor in our in-depth Intel Core i9-14900K review, the new processor performs about 4-6% better than the previous generation i9-13900K did. In games at least this means that the 14900K has a slight edge in performance over the 7950X3D in certain games, though they more or less perform en par in most titles. Outside of gaming however, the 14900K comes out around 5% ahead.

14900K vs 7950X3D Final Word

This has been our comparison between the 14900K vs 7950X3D. As we get more performance data to answer the “AMD or Intel” question, we’ll be updating this page accordingly. Overall the 14900K is more powerful on paper an in non-gaming scenarios, but the AMD’s 7950X3D, with its X3D component, performas similarly in most games. In short: the new 14th-generation Intel CPUs don’t appear significantly different from the previous generation.
