A new analysis reveals something that we have already felt from afar, but when represented graphically it is very visible and easy to understand. How much power is consumed by the latest gaming APUs from Intel and AMD? What is the most energy efficient? And of course what’s the difference in watts between them? By answering these questions we will come to the conclusion of effectiveness, so let’s go.
Efficiency in Intel vs AMD, a new fight between Cézanne and Rocket Lake for PC
Original data table
M / B is unified with the mini-ITX from ASRock
For the 4750G, data from one year ago is used as is. Therefore, the presence or absence of wireless is not unified, but the effect on the measured value is very small https://t.co/ySTbhABqTF pic.twitter.com/tW1fnnx4Ba– V Ρ C F (@ vpcf90) August 10, 2021
Anything that saves us in watts every day is important since electricity is at its highest historical price since we set records. This is why having a more efficient processor is not stupid and to compare we have three big exponents such as Ryzen 7 5700G (Cézanne), the i7-11700 (Rocket Lake-S) and the Ryzen 7 4750G (Renoir).
The comparison and the graph that we are going to see measure the relation between the power consumption of each APU / CPU, the frequency and the score that was obtained in Cinebench R20, where all the power states are logically in PL2 and PTT.
The system and its conditions as well as its configuration are described at the bottom of the graph itself, where the most curious is undoubtedly the configuration of the fan and its RPM / º C curve, since 100% is only reached when the processor it has reached or exceeded 80 ° C.
AMD beats Intel with lower power consumption and higher performance
There isn’t too much discussion here as you can see. The table is really very graphic, where we can already see that at the same frequency AMD is significantly higher than Intel. Starting with the consumption of laptops with ultrabook figures such as 15 watts We see that AMD not only achieves a higher frequency, but the performance is much higher.
But what is most striking is undoubtedly that Intel has a decrease in performance, while on the contrary in consumption it is higher even by reducing the frequency. From this jump, the data skyrockets and the curve becomes more diagonal, mainly between 2.7 GHz and 3.1 GHz.
On the other hand, AMD is not only more efficient, but also has a much higher amount of available frequencies than Intel, which allows it to better handle power regardless of the state of the processor. The curve is much smoother, although the rise is more important at the end of it, but we especially notice that the consumption jumps are much lower than those of Intel even if it also obtains frequency jumps. 100 MHz at some points.
Renoir, on the other hand, offers much worse data with a much more vertical curve, which shows AMD’s architectural leap with Cézanne and Zen 3. The data does not lie: 85 watts against 140 watts, better distribution of power by jumps in MHz. , better performance compared to its rival and all at exactly the same price (i7-11700K to compare just as both processors are unlocked, the 11700 is 60 dollars cheaper and it is locked on overclock). Therefore, with an AMD processor, you will consume less electricity and pay less on your electric bill.
