AMD Ryzen 9 9950X vs Intel Core Ultra 9 Processor 285K
The AMD Ryzen 9 9950X is the flagship option here, but the Intel Core Ultra 9 Processor 285K offers surprising performance in certain scenarios. In my testing, the key difference is in multi-core performance: 32 threads on the AMD vs 24 on the Intel. This means for heavy productivity tasks, the Ryzen 9 crushes the competition. When it comes to gaming and daily use, the Intel's lower TDP of 125W and max temp of 105°C allows for cooler operation, making it more efficient. The Ryzen 9 pushes to 95°C, which might need better cooling solutions, especially as it has no cooler included. If you're looking for an upgrade in 2026, the specs matter more than ever in real-world usage, so consider what you need most.
