Asus VivoBook 17 S712FA Laptop Review: Low Weight, Low Price

0 7

We stress the system with synthetic loads to identify for any potential performance issues. When running Prime95, the CPU can be observed struggling between 400 MHz and 2.8 GHz for the first few seconds which is very odd for any processor. It eventually stabilizes at 2.8 GHz and at a very warm core temperature of 97 C as shown by our screenshot below.

If the power profile is set to High Performance mode, however, clock rates will inexplicably throttle to just 400 MHz with small bursts up to 4.3 GHz. Switching the power profile back to Balanced mode fixes this. This abnormal behavior means users should stick to Balance mode in order to get the most performance out of the laptop until Asus can address the issue.

If running both Prime95 and FurMark simultaneously, CPU and GPU clock rates would cycle between 1.8 GHz to 3.5 GHz and 600 MHz to 1150 MHz, respectively. Fan noise remains constant while core temperatures do not.

Running on battery power will limit performance. A 3DMark 11 run on batteries would return Physics and Graphics scores of 6245 and 1686 points, respectively, compared to 7764 and 1960 points when on mains.
