Power consumption during gaming
When I evaluated the first metrics, I rubbed my eyes in amazement, tested the measurement setup again, and just wondered. The Ryzen 7 7800X3D is not only one of the fastest CPUs in the sum of all gaming benchmarks and resolutions, but together with the Ryzen 7 5800X3D and the Ryzen 9 7950X3D it is also by far the most frugal. I certainly wouldn’t have expected this to be so extreme in this form, but I am somewhat flashed because it is even less than I had hoped for before the test anyway. There is no need to comment on all these measurement series, that stands for itself. And that’s when I started to like the title again.
Intel can of course also be fast in gaming, even really fast. But the cost of this adequate performance then quickly brings tears to the socket’s eyes, while the Ryzen 7 7800X3D only needs plenty of half of what we have to pump into the Intel Core i9-13900K on average. This is a humiliation of the first order.
Gaming efficiency
Let’s now look at the efficiency that has already been mentioned many times. It is, as just written, a total humiliation. Not only for Intel, but also for all other Ryzen 7000 CPUs without the X3D in the nomenclature! Even though the previous efficiency winner Ryzen 9 7950X3D is similarly frugal, it is hardly faster. And the Intel Core i9-13900K? It is sunk into the energetic floods with a vengeance. Plop!
Power consumption and efficiency in mixed workloads
This is where AutoCAD comes in handy, because there are no performance-hungry rendering interludes. The CPU load is usually below 70 percent, often enough even much lower, which reflects the normal workday quite well. In addition, the Cadalyst run is quite consistent, also in terms of power consumption on systems with different speeds. Well, the Ryzen 7 7800X3D is not one of the winners of this benchmark, because the clock is still quite sufficient, but despite everything, the performance record is a real scent mark.
Now you can put the score in relation to the power consumption to show the efficiency. Here you have to admit defeat to the Intel Core i5-13600K and also the Ryzen 9 7950X3D, but it is still enough for all other CPUs, including the rest of your own family. Chapeau.
Full power during rendering
With a measured average of 89 watts over 5 minutes, we are still well below the PPT and take a well-deserved 1st place in the drinking competition. The 8-core is even more frugal than the Core i5-13600K, which also runs into the PPT limit. Coolable all this is also still quite neat. Well, it’s only just under 90 watts. The temperatures are at a maximum of 65°C with the lab water cooling, and at a maximum of 73°C after 5 minutes of render load with a normal 240 AiO.
If you put power consumption and performance at full load in relation to each other, then it becomes a triumph for the Ryzen 9 7950X3D and the ryzen 7 7800X3D, because no other CPU even comes close in terms of efficiency. Well done! This is really fun and astonishing in equal measure.
