ASUS ROG Zephyrus S GX502 Glacier Blue

Performance, gaming, and battery life

Before we begin talking about the performance, let us just talk about the specs for one moment. The ASUS VivoBook Ultra A512 is created to be a laptop that is oriented for those who want long-lasting battery life with sufficient performance for web browsing, some Netflix, YouTube, Spotify, and a perhaps a little bit of Spotify.

That makes this laptop actually very decent for students and for general purpose since it is rather lightweight and thin, yet comes with a fantastic keyboard with ergonomic ErgoLift hinge design too.

As for the specs, the one we have here for review is specifically powered by:

ASUS VivoBook Ultra A512
Display 15.6-inch 1920×1080 resolution with NanoEdge thin bezels
CPU Intel Core i5-8265U
GPU Intel UHD Graphics 620
NVIDIA GeForce MX250 with 2GB VRAM
RAM 4GB DDR4 2400MHz
Upgradable to up to 16GB DDR4 2400MHz
Storage 512GB M.2 NVMe PCIe Gen 3 x2 SSD
2.5-inch storage bay (empty)
Battery 37Wh battery


Surprisingly, the Core i5-8265U and NVIDIA GeForce MX250 are quite powerful here – relatively, of course. We put the VivoBook Ultra A512 through our usual test and revealed that the scores are quite decent.

In day-to-day use, my only complaint is the 4GB RAM. That is clearly insufficient for the number of apps and Chrome tabs that I work on concurrently, and definitely not enough for Adobe suite of software. You can still work on Lightroom and Photoshop with just 4GB RAM, though it is sluggish and advisable to get at least 8GB RAM.

As for benchmarks, here are a few for reference on how the ASUS VivoBook Ultra A512 performs.

Though, ASUS outdid themselves by including a speedy 512GB NVMe PCIe Gen 3 x2 SSD in this laptop. I never would have guessed that ASUS would put an NVMe SSD inside a laptop of this price range. Its speeds are pretty much similar to the Kingston A1000.

For a closer-to-life test, we tried a few games here. Here are the games we used to test and the results.

ASUS VivoBook Ultra A512 game tests
Game title Graphical setting FPS
A Hat in Time High performance preset About 40 to 50
Apex Legends Lowest Above 30
CS:GO Highest possible settings About 55
Dota 2 Highest possible settings About 30 during team fights
Fortnite High preset 35
HITMAN 2 Lowest possible settings Consistently drops to 18
Overwatch Medium preset Above 55

I’d say the MX250 is actually fairly decent here as it manages to run some high-end games at a rather high frame rate with decent graphical quality. Of course, Dota 2 and CSGO can run smoothly without any issues at all – and that is great news as these two games are still rather famous. Fortnite on the other hand, is able to run beautifully on this machine.

Battery life

From the specs, we can see that the VivoBook Ultra A512 comes with a 37Wh battery. On paper, it might seem tiny in comparison – but let’s not forget that this laptop is meant not that power-hungry.

Overall, we got about 4 hours and 20 minutes of use with a few hours of sleep in between the usage. We were using it with lots of heavy browsing on Chrome together with some YouTube videos, some light Photoshop work, and lots of typing.

As for charging, it took us about 2 hours to charge the laptop from 15% to 100% while turned on but idling.

Also, the power brick is pretty tiny – yet manages to push out the maximum of 65W. However, it is still not as tiny as the j5create’s tiny little 65W charger.
