Pricing And Availability
| CPU | MSRP | Current Price |
|---|---|---|
| Core i9 12900K | 💲589 | 💲363 |
| Ryzen 9 7900X | 💲549 | 💲382 |
| Price Difference | 7.2% | 5.2% |
Even though there is not much of a price difference between the two chipsets alone, the R9 7900X costs about 5.2% more. That’s because the AM5 socket, being new, costs more than the 1700 socket. However, it is highly unlikely that the overall pricing of the two CPUs will affect your purchase decision.
Final Verdict – What We Recommend
Ryzen 9 7900X: The Ryzen 9 7900X was mildly better in average framerates than the Core i9-12900K. But that advantage comes with certain demerits such as a 5.2% price hike. The rest of the factors like power consumption and thermal efficiency are not very distinct so they don’t hold anything against the CPU.
Core i9 12900K: On the flip side, the Intel Core i9 12900K excels in the %1 lows and gives similar average framerates as well as a cheaper price and similar power and thermal draws. Moreover, it gets a little smoother than the AMD processor in many instances, which makes its case pretty powerful against its competitor.
We would say this comparison is a toss-up between the two. If you have an existing Intel 12th-generation platform, we recommend sticking with the 12900K. Conversely, if you want to build a PC that you could be upgrading for years, the Ryzen 9 7900X gives you a great entry point into the expectedly long life of the AM5 platform.
FAQs
Definitely, the R9 7900X packs a bunch of power and features that make it a suitable processor in the long term. For instance, it has support for both DDR5 and PCIe Gen 5.0, which means that you will have no issues pairing this chipset with the latest high-end RAMs and GPUs of the future.
Going through the benchmarks, it is as clear as day that the Core i9-12900K is still undoubtedly a powerful CPU. In most games we tested, the i9-12900K was behind its latest competition with just a small difference in FPS.
As seen in the benchmarks, both rigs were powered by the Corsair RM850i 850W. So, you should be good to go with a similar PSU.
