Overall Gaming Performance

Average Framerate

Even though it was a rocky start, the 9950X pulled through in our testing, with an average advantage of around 6.85% in the eight games we tested. This difference was not noticeable at such high framerates, but the extra headroom is always nice.

1% Lows

The minimum framerates had a smaller lead, with an average advantage of 5.5% for the 9950X. Surprisingly, one game had the 9950X performing worse than the 7900X in 1% lows, but the chip pulled ahead in the end.

Overall, based on these results, we are very happy with the 9950X’s performance. Of course, performance is not the only metric on which to judge a processor. We will discuss the other metrics below.

Power Consumption

Our testing showed that the Ryzen 9 9950X took around 8.7% more power than the 7900X. This is understandable, considering the small difference in process size compared with the higher tier of the 9950X compared to its rival.

Temperatures

The Ryzen 9 7900X ran around 1.1% cooler than the 9950X, a difference that can easily be disregarded. This means that overclocking these CPUs should reveal similar thermal limits, which indicates the performance delta should remain similar at higher power levels.

Price

Our research shows that the Ryzen 9 7900X can be had for a bargain when compared to the 9950X. As of the 5th of September, 2024, the price of the 9950X is around 87% higher than the Ryzen 9 7900X. The price of this processor in a used condition is even lower than the one mentioned.

What We Recommend

Ryzen 9 7900X: Though this processor was up to 12.5% worse in our game testing, the overall deal this chip gives is very hard to argue with. The price of the 7900X has fallen so much over the months since it was released, giving it an excellent price-to-performance ratio.

Ryzen 9 9950X: This is the best of the best from AMD’s Ryzen 9000 series of processors, and it does as it promised. The performance is around 7% higher on average while having minimal difference in power consumption. The price, however, makes this processor a hard sell.

Now that we’ve thoroughly discussed the Ryzen 9 9950X vs Ryzen 9 7900X, a general recommendation is due. In our opinion, getting the 7900X is much better for the average consumer, for its accessible price. However, if you want the latest and greatest, get the 9950X.
