Asus Zenfone 5Z Review – Is It Really a Budget Flagship Killer?

Hardware & Performance

The Asus Zenfone 5Z greatest selling point is its performance enhanced by a great system optimization

Now moving to the real deal is the high-end hardware and beast-like performance of the Asus Zenfone 5Z. The heart of the flagship is the latest Snapdragon 845 SoC coupled with 6 gigs of RAM. Of course, there are several options as well ranging from 4 to 8GB RAM and 64 to 256GB ROM. Compared to the other phones, Asus provides one extra variant which is the ultra-affordable 4GB version. Asus doesn’t mention if the storage is UFS 2.1 or not, but with the speed test, we bet it is.

Interestingly, like the rest of SD 845 featured smartphones, Asus Zenfone 5Z will simply surpass your expectations. Just throw anything at it, PUBG Mobile at HDR setting, Full-HD video decoding,10+ multiple apps opened at the same time, the 5Z won’t disappoint you even with the slightest lag.

For a much better power management, the AI boost feature allows you to shred some power consuming apps with one click to make room for games or any resourceful app.

To check the actual performance, we did some tests/benchmark and compared them with the other high-end flagships such as Mi 8 and OnePlus 6. Here are the results:

AnTuTu Benchmark Test (To Check Overall Performance)
Intro: The world’s first mobile phone/tablet hardware performance evaluation tool can comprehensively examine the performance of various aspects of the equipment, including user experience, and visualize the ranking. It supports multiple mainstream platforms, running points can be compared across platforms. The test comprises CPU, GPU, Memory, UX, and finally the total performance.

The Asus Zenfone 5Z scores around 250,000 points which are better than 99% better than the current smartphones on the market. The only phones scoring more are OnePlus 6, Mi 8, Samsung Galaxy S9 and so on. OnePlus 6 is only 23,000 points ahead of the 5Z but Asus Zenfone 5Z is slighter cheaper as well.

GeekBench Test (To Check CPU Performance)
Intro: Cross-platform CPU performance testing tools can accurately reflect the device’s CPU single-core, multi-core performance. Test load simulation of real-life application design, the result is more meaningful, but also to measure the GPU graphics computing performance. It’s a detailed test comprising of Single-core and Multi-core performance.

The single core performance (2418 points) is incredible along with a good multi-core performance (8707 points). That’s how much raw power a Snapdragon 845 powered phone must yield.

GFXBench Test (To Check GPU performance)
Intro: The cross-platform, cross-API 3D benchmark software accurately reflects the graphics performance of the device’s GPU. Multiple test scenarios can fully examine the OpenGL ES graphics performance of the device and perform battery life tests. GFXBench offers OnScreen and OffScreen test methods. When the screen is running with the native resolution of the device screen, the off-screen display is unified to 1080p resolution, facilitating cross-device comparison.

The offscreen frame rates per second were one of the best, thanks to Adreno 630. The phone is suitable for extreme high-end graphics performance on the Full-HD resolution with an average 60+ fps.

PCMark Test (To Check Daily Usage Performance & temperature)
Intro: PCMark is a test software that considers the overall performance. This performance can accurately reflect the processing performance of the daily use of the smartphone, multiple daily test scenarios, such as web browsing, video editing, document writing, picture editing, etc. It should be noted that PCMark’s lean-to-energy ratio is higher, which means that the higher the score of the mobile phone the more balanced power consumption and performance it is.

In the PCMark test, it scored around 8163 points, thanks to the highly optimized SoC and high capacity battery. The phone can meet the needs of advanced users expecting to watch Full-HD movies and videos and play high-end video games on mid graphics.

Androbench test (To Check Memory Performance)
Intro: AndroBench is a benchmark application that measures the 4K random storage performance of Android devices, including internal or external storage.

The reading and writing speed of Asus Zenfone 5Z is pretty fast. The speed test proves that the memory type is UFS 2.1 even though Asus hasn’t mentioned it.

Gaming on Asus Zenfone 5Z

For the mobile gamers out there, Snapdragon 845 is the best SoC one can ever dream of for a smooth gaming experience at the highest settings. I was able to get 30+ fps all the time while playing the most high-end smartphone games: Modern Combat 5 and PUBG Mobile on highest settings. Here are some videos and screenshots of the gameplay:

1) Gaming Test 1: PUBG Mobile (HDR + anti-aliasing + Full-HD+)

The smartphone does get hot after 20 minutes of gameplay. Since the rear is glass, it isn’t that noticeable. Asus Zenfone 5Z doesn’t have a cooling system like the Black Shark or Meizu 16, however, if they had added one, it would cause a further increase in the price tag. Moreover, I believe that a pure metal or polycarbonate body needs a cooling system, not a glass one.
