So sánh cpu helios x20 với sanpdragon 625

We have already compared SD 650 vs Helio X20 vs SD 652, but this is the first time we are going to compare Snapdragon 625 Chipset. In the article, we will compare the benchmark of 3 Xiaomi Smartphones; Redmi Note 3 (Snapdragon 650), Redmi Note 4 (Snapdragon and Mediatek Version). Xiaomi Launched Redmi Note 4 in India with SD 625 CPU, but the same model was launched with Helio X20 in Home Country (China). Today we will compare these 3 CPUs and its Antutu and Geekbench Benchmark Score.

Snapdragon 625 vs Snapdragon 650 vs Mediatek Helio X20 Specs

Snapdragon 625: 14 nm Chipset, octa-core ARM Cortex A53, CPU clock Speed up to 2.0 GHz, Quick Charge 3.0, LPDDR3 RAM with 933MHz Speed, Adreno 506 GPU, 64-bit architecture

Snapdragon 650: 28 nm Chipset, hexa-core (2 x ARM Cortex A72 + 4 x ARM Cortex A53), CPU Clock Speed up to 1.8 GHz, Quick Charge 3.0/2.0, LPDDR3 RAM (dual-channel) with 933MHz Speed, Adreno 510 GPU, 64-bit architecture

Mediatek Helio X20: 20nm Chipset, deca-core (2 x ARM Cortex A72 @ 2.3 GHz + 4 x ARM Cortex A53 @ 1.85 GHz + 4 x ARM Cortex A53 @ 1.4 GHz), LPDDR3 RAM (dual-channel) with 933MHz Speed, ARM Mali 780MHz GPU, 64-bit architecture

The Clock Speed mentioned above is the maximum speed that the CPU can run at. So let’s know the clock speed and we will compare all the models with 3GB RAM.

Redmi Note 4 (Mediatek Version): 2 X ARM Cortex A72 @ 2.1GHz + 4 x ARM Cortex A53 @ 1.8 GHz + 4 x ARM Cortex A53 @ 1.4 GHz)

Redmi Note 4 (Snapdragon Version): 8 X ARM Cortex A53 @ 2.1 GHz

Redmi Note 3 (Snapdragon Version): 2 X ARM Cortex A72 @ 1.8 GHz + 4 X ARM Cortex A53 @ 1.4 GHz

Conclusion: Which one is the best?

If we talk about the overall performance, Snapdragon 625 is certainly a looser. Snapdragon 625 Chipset is smaller in size so it will be power efficient and will make the device run longer, but it loses in all other aspects. So I don’t see a reason that users should buy a Smartphone with Snapdragon 625 when you can get Smartphones almost in the same price that feature Helio X20 or Snapdragon 650. It’s tough to announce a Winner between Snapdragon 650 and Helio X20 because Helio X20 is the winner as far as CPU Benchmark is Concerned, but SD 650 beats Helio X20 in Graphic Benchmark. If you are among those who are fond of playing games, then I would suggest buying Smartphone with Snapdragon 650. If you play games occasionally, then the device with Helio X20 Chip is the best option.

I’ve been using Vernee Apollo Lite smartphone with a Mediatek Helio X20 deca-core ARM Cortex A72/A53 processor coupled with an ARM for a little over a year. Recently, I’ve received Xiaomi Mi A1 smartphone for a Qualcomm Snapdragon 625 SoC featuring eight ARM Cortex A53 cores and an Adreno 506 GPU.

In theory, the latter is a downgrade, and the Xiaomi phone is indeed quite slower in Antutu with overall score of 60,161 points against 85,840 points in the Mediatek phone. 3D graphics performance is also lower with 12,849 vs 17,828 points. Both smartphone have the same resolution (1920×1080), so it’s a little confusing to be told you’d “better to play games in low quality mode” for the Mediatek phone, and “game performance is mid-level” for the Snapdragon one.

But anyway Helio 20 should work better in 3D games than Snapdragon 625 if we are to believe the numbers. Most apps run fine on Vernee Apollo Lite, but one game I play is sometimes extremely sluggish, especially in a specific section of the user interface. That game is CSR Racing 2 (aka CSR2), and the section is called “Rare import” where the game will sometimes freeze for a few seconds apparently while rendering some animations. The phone may also overheat while playing, and I’ve used Boots hot & cold pack a few times to keep it cool and make the game playable, but that’s another story 🙂

So I was interesting to find out if CSR2 would also freeze in Xiaomi Mi 2, and see how it performs while actually playing, so I placed both phones side-by-side to check it out.

The video above does not actually show the worst case for the Mediatek processor, as sometimes the animations in “rare imports” would freeze for 3 to 4 seconds and several times during the process. So far, Xiaomi Mi A1 has been working very well in that section. In the video I mentioned that I could not see much difference between the two phones during playback, but after playing further I found the Xiaomi Mi A1 is also smoother to play. After also double-checking the video, it’s also clear there are less texture details and fewer objects shown in the Snapdragon 625 phone, as shown in the photo below with trees shown in Vernee Apollo Lite, but not the Xiaomi phone.

The app is likely auto-detecting the phone performance, and it works well for one, and not quite as well for the other. It’s also possible the developers focus on the most popular phones from Samsung, Motorola, HTC, and other brands which are usually equipped with Exynos or Snapdragon processors, rather than Mediatek ones. I could not find an option to manually adjust the image quality/resolution in the game.

The conclusion is that you can’t simply look at benchmarks to find out if a particular game will work well on your phone. In this case Helio X20 is closed to 40% faster in Antutu 3D GPU benchmark, but the user experience is much better with the Snapdragon 625 phone, albeit at the cost of a little less graphics details. Other games will likely differ depending on the implementation.
