Power consumption and efficiency in gaming
There is a glaring difference between Intel’s new CPUs in terms of drinking behavior. While the Intel Core i7-14700K is at the top of the glow trumps, the i9-14900K is now close on its heels. The AMD CPUs without 3D cache are always thirstier than the rest when they drift into the partial load range. But at the socket, it once again becomes clear where and how Intel buys the increased performance in gaming
Let’s now look at the already briefly mentioned efficiency. It doesn’t make any sense to lift the power limit at Raptor Lake (refresh) and there were even situations where too much power (without thermal limit) pushed the FPS rates down again in a counterproductive way. If you mainly play games, you can even limit the Core i9-14900K to 125 watts without a guilty conscience and performance losses. The device still runs well, even without a supposed performance crown. The i7-14700K is completely overpowered and shockingly inefficient, while the Core i5-14600K is the only new CPU that can beat its predecessor in performance AND efficiency. That’s something to think about.
Power consumption and efficiency in mixed workloads
This is where AutoCAD comes in handy, because there are no power-hungry rendering interludes. The CPU load is usually below 70 percent, often enough even much lower, which reflects the normal workday quite well. Furthermore, the Cadalyst run is quite consistent in terms of power consumption on systems with different speeds. Here, the Intel Core i9-14900K puts itself rather ingloriously in the limelight, because it sinks like a hole in the trio infernale together with the i9-13900K and the i7-14700K. In comparison, the Core i5-14600K is still decent, especially since it performs excellently.
Now you can put the score in relation to the power consumption to map the efficiency. The three refreshed Raptors couldn’t be positioned more differently. While the Core i5-14600K only just loses the efficiency crown against the Core i5-13600K, the thick-ship Core i9-14900K makes party at the socket together with the i7-14700K and the i9-13900K.
Full performance during rendering
Here, the Core i5-14600K is in the upper midfield, while the big CPU allows itself a decent energetic load. With almost 289 watts on average, the cranked-up Core i7-14700K surpasses all other CPUs with a thirsty gesture of nonchalance and is almost 50 watts above the Ryzen 9 7950X. Nice really is different and it pushes the AiO to the edge of a vapor chamber.
If you put power consumption and performance under full load in relation, Raptor Lake only sorts itself into the upper midfield. But at least it doesn’t quite turn into a disaster, also because of my small brake at the power limit, which isn’t really one, because I only keep to the specs. Only the Core i7-14700K becomes an energy disaster. With announcement. But there was no other way to get it running stably, and Intel will know why they don’t officially sample the part.
