The battery mode of Ruilong 4000 notebook is inferior to Intel's 11 generation core? Linux platform test is not quite true

Intel recently launched the challenge of "poor performance in battery mode" to AMD notebook competitors, which has caused great controversy among netizens and user groups.In order to give you a more comprehensive reference, Phoronix also carried out a detailed comparative test on Lenovo using Renoir's r5-4500u processor and Dell's XPS 13 9310 laptop with tiger Lake Core i7 processor under the Ubuntu Linux operating system.


Alibaba cloud's double 11 global carnival season continues - the first year of dual core 8g cloud server is 286.44 yuan


To be fair, both devices disable sleep mode in battery mode in the system and set the screen brightness to a minimum.


Previous benchmark tests have shown that although the r5-4500u is not a high-end Renoir mobile processor, it can still compete with the core i7-1165g7.

Even so, this paper focuses on the difference of performance / endurance strategy between the two platforms in battery / external power supply mode. In this paper, only a few representative test items are selectedPhoronixWebsite view.



When viewing the CPU peak frequency, the ru-5-4500u has an average of 2.9ghz under power on and 2.5GHz in battery mode. However, in both modes, it can reach 3.9-4.0 GHz.

Of course, this preference setting of the Renoir mobile platform also helps to reduce the operating temperature of the laptop when working on the laptop.


Tiger Lake platform has consistent performance in battery / power mode, and the r5-4500u is about 3 seconds slower. If it is not a batch operation, the actual feeling is not obvious.


Of course, the temperature performance of r5-4500u is still brilliant. And in the continuation of Darktable RAW and GIMP image processing software, the endurance of Renoir platform is more awesome.


In rawtherapee multithreading performance test, the performance difference between battery and external power supply is not significant. In addition, with the advantages of six Zen 2 cores, r5-4500u performs better than i7-1165g7.


(3) Ocrmypdf test: the performance of Renoir platform in battery mode is not inferior to the high-end competitive products certified by Intel Evo, and even achieves a big lead in multi-threaded performance.


Hugin open source panoramic photo mosaic software test: the frequency of r5-4500u in battery mode is slightly lower, but its performance is better than i7-1165g7 whether it is connected or not.


(4) Referring to the CPU peak frequency during the whole benchmark test, the average frequency of Lenovo r5-4500u model in battery mode is 2.4ghz/2.7ghz in power on mode.

by comparison,DellThe i7-1165g7 frequency of the XPS 13 9310 high-end notebook is 2.4/2.6ghz. In addition, the two strategies are also very different in temperature control.

For consumers, it is obvious that they need to consider their actual use needs, and then make a wise purchase decision.
