AMD Ryzen 9 9950X vs Intel Core Ultra 9 285K: Detailed Comparison
Specs Comparison
Here are the specs of Ryzen 9 9950X and Intel Core Ultra 9 285K:
In terms of core count, these CPUs are very different. One follows SMT, whereas the other stopped the use of SMT (Hyperthreading). Both support Gen 5 and are about the same TDP levels in practical use cases.
Synthetic Performance Comparison
The numbers below represent an overall roundup of publicly available information. As the results speak, in terms of synthetic benchmarks these CPUs are very closely matched. That said, this means that any multi-core task you throw at them will perform equally well on either.
Gaming Performance Comparison
The results below are taken from Testing Games’ YouTube channel, where the person conducted this test with all games on the max settings preset, using 6000MT/s Dual Channel DDR5 Memory with the RTX 4090 at 1080p.There is around a 10% difference between the two, making them suitable for gaming alongside content creation work. If you play at 1440p or higher, then this discrepancy disappears, so for gaming, these CPUs are gems.
Price Comparison
The Ultra 9 currently retails at Amazon.com for $559, and the Ryzen 9950 X for $515. Pricing information is accurate as of August 02, 2025, and can change without notice.
Final Verdict on AMD Ryzen 9 9950X vs Intel Core Ultra 9 285K
For workstation use, both CPUs are great picks. They will consume immense power and require incredibly potent coolers to keep them cool. However, the Ryzen is very aggressively priced and is a much better buy. Intel seems to be at a dead end, as the Nova Lake is rumored to have a new socket, requiring you to buy a new motherboard. For strictly gaming, if you only need 16 cores, then go for the 9950X3D variant or the 9800X3D, the current king for gaming.
