The Power and Performance Differences Between Three Ryzen 9000 Chips: An In-Depth Analysis
In this article, we'll dive into the power and performance differences between three Ryzen 9000 chips: the AMD Ryzen 9 7950 X3D, the Ryzen 9 9950X, and the Ryzen 9 7950X. We'll explore their power consumption, thermal performance, clock speeds, and gaming capabilities to help you decide which chip is best suited for your build.
**Power Consumption**
The first thing we want to look at is power consumption. The undervolted 9950X, whether or not we're using the temp limit, saw relatively similar peak power draw in Cinebench Plus, plus or minus 3 to 9 watts versus stock. However, with PBO alone, its peak CPU package power draw did drop by 15 watts below stock and 17 watts below itself with PBO and the temp limit enabled, which brings down the total system power draw slightly. In games, however, this drop in power consumption is not as significant, as it's still not as low as the 7950 X3D.
**Thermal Performance**
Next up is thermal performance. Adding a temp limit of 85°C brings the 9950X's Cinebench temps down to 85°C, which is a 10 or 11 degree drop from stock or, if we had just done the PBO overclock with no temp limit in place, the undervolted temps are also lower when gaming, hitting 79-80° at peak, down from 87°C at stock. Both undervolt profiles of the 950X averaged a temperature of 72°C or 7° below stock and even slightly cooler than the 7950 X3D.
**Clock Speeds**
Now, let's look at average clock speeds in a multi-thread Cinebench run. The 950X with PBO and temp limit hit 4,222 MHz, which is about 200 MHz slower than with just PBO and about 100 MHz slower than stock. Despite this, the temp-limited 950X outperforms its stock profile with a Cinebench multi-thread score of 4296, that's about 5% faster than stock and 3% slower than with PBO only.
**Real-World Performance**
In Adobe Premiere Pro, the temp-limited 950X performs somewhere between its stock profile and PBO-only profile. It finished the 4K export 4.5% slower than it did with PBO only and although it was only 75% faster than its stock profile, the temp limit allowed it to run 10°C cooler on average, which is still a big win.
**Build-Specific Considerations**
Now that we've explored the power and performance differences between these three Ryzen 9000 chips, let's consider what this means for our specific build. We're talking about a very niche scenario – inside of the tiny Dela 3 case, a 4L chassis with an RTX 4060 Ti. In gaming, it's kind of a wash; you can give half a point I suppose to the 7950 X3D, as it did have stronger frame times and better consistency overall.
**Compute Performance**
However, in compute performance, the 9950X is definitely the winner. It was faster across the board, sometimes not by much and other times by a lot. Overall, it's the more powerful chip in this regard.
**Power Consumption Award**
The power consumption award goes to the 7950 X3D, as even undervolting the Zen 5 chip doesn't really get you close to the stock x3d's power draw. Thermal performance is also a win for the 7950 X3D, as it just runs cooler out of the box.
**Price Considerations**
Finally, let's consider price. The 7950 X3D is about $125 cheaper right now than the 9950X at launch, and it's available on Amazon for $525. Given these price points, it's clear that the 7950 X3D is the better value.
**Conclusion**
In conclusion, while all three Ryzen 9000 chips have their strengths and weaknesses, the 7950 X3D comes out on top in our analysis. It offers superior thermal performance, slightly lower power consumption with undervolting, and a more affordable price point at launch. The 9950X, on the other hand, is still an excellent choice for those who need extreme compute performance.
That being said, if you do have money to burn and really need the extra compute performance, the 9950X may be worth considering. However, given the current pricing, the 7950 X3D would be our pick for this build unless you have specific requirements that can't be met by the Zen 4 chip.
We'll continue to test these new chips in the coming weeks and months to see how they hold up in real-world performance. In the meantime, if you're considering which Ryzen 9000 chip is best for your build, we hope this analysis has provided some valuable insights.
