Power & Temperature Testing
On this page, we are going to test the power draw on the CPUs, testing multi-core performance in Cinbench 2026 running for 15 minutes. We are also going to test the CPU package temperature using the same method.
The TDP of the AMD Ryzen 7 9850X3D remains the same as the Ryzen 7 9800X3D at 120W. In our testing, the actual peak package power reported by HWiNFO64 in the multi-core benchmark was around 141W-145W for both CPUs. Technically, the Ryzen 7 9850X3D was a little lower by 2%. It is good to see that it does not consume more power than the Ryzen 7 9800X3D, considering it is clocked 400MHz faster. This is much less than the Ryzen 9 9950X3D by 29%, and a massive amount less than the Intel Core Ultra 9 285K at 48%. The Ryzen 7 9850X3D does consume more power than the lower-powered Ryzen 7 9700X by 61%.
The AMD Ryzen 7 9850X3D had a package temperature of 86.2 Celsius at max, which is right in-line with the temperature of the Ryzen 7 9800X3D. It is good to see that the Ryzen 7 9850X3D did not run hotter than the Ryzen 7 9800X3D, despite it having a 400MHz clock speed increase. This runs warmer than the Ryzen 9 9950X3D and Ryzen 7 9700X, but cooler than the Intel Core Ultra 9 285K slightly.
CPU Clock Speed Comparison
Multi-Core
We wanted to compare the clock speeds between the Ryzen 7 9850X3D and Ryzen 7 9800X3D. Therefore, above the left screenshot is of the Ryzen 7 9850X3D, and the right screenshot is of the Ryzen 7 9800X3D. Both CPUs are running the Cinebench 2026 Multi-Core benchmark. We can see that the maximum clock speed increases from around 5.18-5.2GHz up to 5.4-5.585GHz on the new Ryzen 7 9850X3D running all-cores.
Single-Core
In the two screenshots above, we are now looking at single-core clock speed between the Ryzen 7 9850X3D (left) and Ryzen 7 9800X3D (right) in Cinebench 2026 single-core testing. We can see that the single-core frequency goes from 5.225GHz up to 5.470GHz on the Ryzen 7 9850X3D. This gives you a general idea of what to expect with core clock speed boosts with the new CPU.
