AMD Ryzen 9 9950X vs. Intel Core i9-14900K

Which flagship is worth your hard-earned cash?

AMD Ryzen 9 9950X and Intel Core i9-14900K lying on a bed of grass.

On the surface, pitting AMD Ryzen 9 9950X vs. Intel Core i9-14900K is a pretty one-sided affair. While Team Red doesn’t do much to push the needle forward with the same topology as its predecessors, the flagship dominates most tests with a convincing lead, at least until price comes into the equation.

The main question in this Clash of the Titans is, how much of a premium are you willing to pay for the performance uplift? We’ve conducted fresh application and game benchmarks that should help you figure out the best CPU upgrade for you.

Core i9-14900K24 / 32125/253W36MB3.2GHz6.0GHz$589 / £579

Just like AMD Ryzen 7 9700X and Ryzen 5 9600X, Team Red’s flagship holds no surprises with the same core-and-thread count as the past two generations. This places it on par with Core i9-14900K, featuring 32 threads apiece, although Intel sneaks a few extra efficient cores in there for good measure.

Although the company hasn’t done much to change AMD Ryzen 9 9950X vs. AMD Ryzen 9 7950X3D, the new chip still has plenty more L3 Cache than Intel. This should give it a leg up in gaming, but it’ll still struggle to justify the extra cost when Core i9-14900K has fallen from a comparatively lower launch price to a current MSRP of £543.

It does make you wonder just how well the X3D cache will perform once it inevitably reaches Ryzen 9000 processors.

Efficiency

AMD Ryzen 9 9950X has a higher idle power draw at 94W but a lower average 329W consumption over Intel Core i9-14900K, which its 73W and 370W respectively - lower is better.

Efficiency is the pride and joy of AMD’s latest range, and this is no exception. Even though Ryzen 9 9950X gobbles a lot more than its peers to feed its increased core count, it still undercuts Intel’s flagship by a considerable margin. Its higher idle wattage is less than ideal, consuming more than anything else we’ve tested, but that’s the price of performance here.

AMD Ryzen 9 9950X hits 73.4°C under load, while Intel Core i9-14900K hits 92.8°C - lower is better.

Keeping a cool head isn’t easy, but it’s something Ryzen 9 9950X does extremely well at just 73.4°C. Comparatively, i9-14900K is one of the hottest chips to pass through our halls, risking throttling as it climbs towards 92.8°C.

Value

AMD Ryzen 9 9950X earns a Club386 CPU Efficiency Rating of 7.02 over 5.86 for Intel Core i9-14900K - higher is better.

Dividing our Cinebench 2024 multi-core scores by system-wide power consumption gives us our Club386 CPU Efficiency rating. It’s usually a sweep for AMD, and 9950X expectedly follows suit with the second-highest score yet. All the better when remembering it’s the clear winner in most benchmarks.

Intel Core i9-14900K earns a Club386 value rating of 3.68, over 3.56 for AMD Ryzen 9 9950X - higher is better.

Value tells a different story. This time, we divide the same Cinebench 2024 score by launch MSRP. Although AMD is headed in the right direction with a lower recommended price than the previous gen, it still asks a lot for what it is and forgets Intel has already had a series of discounts. At $546.39 currently, Core i9-14900K scores 3.97, widening the lead it already has.

Conclusion

AMD Ryzen 9950X practically runs away with it in most tests, showing a distinct uplift in both gaming and productivity. Of course, you’ll always be wondering what if it followed Ryzen Threadripper Pro and popped more cores on, but it comfortably sits at the top of its stack with a 16C32T layout. Built on top of the AM5 socket, there’s a clear upgrade path that will be supported until at least 2027 and beyond.

At first glance, it looks like the Raptor Lake Refresh champ has fallen from grace, but it has an ace up its sleeve. While Intel Core i9-14900K claims victory in memory speeds, the star of the show is its value, especially after a year of reductions. On average, it’s 15% slower in synthetic benchmarks and 5.8% slower in games at 1080p. Things mostly even out around 1440p and 4K resolutions for them not to be a factor. However, with the most recent discounts, you save 18.8% compared to AMD’s latest.

My first suggestion is to wait and see what Intel has in store with Arrow Lake, which is still on track to debut in 2024. Based on a new LGA 1851 socket, it should bring a rival that’s closer in performance or, at the very least, drive down the cost of Ryzen. Otherwise, 9950X is the easy recommendation. It provides a better upgrade path and reasonable performance uplifts for the price. Besides, costs will eventually even out thanks to its superb efficiency.
