Qualcomm has a very good track of performance in mid-range smartphones. To enhance its performance in entry-level and mid-range section, Qualcomm introduced three new SoCs last month. Qualcomm announced Snapdragon 720G, Snapdragon 662, and Snapdragon 460 chipset with some improvement and new features from its previous SoCs in these series. From the list of new release, here we will talk about Snapdragon 662 processor. The SD662 brings connectivity features like Wi-F 6 and NavIC (Navigation with Indian Constellation) which is a new GPS technology developed by ISRO (Indian Space Research Organization).

So, here in this article we will compare newly released Snapdragon 662 with its previous Snapdragon 665 and Snapdragon 660 (The oldest SoCs in this list). We will review the CPU, GPU, AnTuTu-GeekBench scores, connectivity, camera and display features of these SoCs. We are including MediaTek G70 as well because this SoC also come under the same price segment and designed for the same budget-range audience.

Fabrication process 

To figure out CPU performance of any SoC, we should first know that what fabrication process is been used in the processor manufacturing. The fabrication process tells the distance between the resistors. The least distance between the resistors, the faster and more power efficient CPU will be. So, when you hear the 11nm, 12nm, or 14nm fabrication process, you can get an idea that 11nm>12nm>14nm in terms of power efficiency. Yeah! at-least on the paper.

Starting with Snapdragon 662 and 665, both are built over the 11nm fabrication and most power efficient SoCs in the list. The Helio G70 is built over the 12nm fabrication process and comes third in the list with less power efficient than Snapdragon 662 and 665. With 14nm fabrication process, the Snapdragon 660 comes last in the row. Umm! It is also a fact that Snapdragon 660 is a bit outdated SoC as well.

CPU Performance

Now coming to the CPU architectures of SD662, SD665, SD660 and MediaTek Helio G70. All four SoCs are the octa-core processors with a 64-bit memory architecture. Here, both the SD662 and SD665 have identical CPU features. Both have four high performance Kryo260 Gold Cortex-A73 cores clocked at 2.0GHz and four power efficient Kryo260 Silver Cortex-A53 cores clocked at 1.8GHz. The other member in Snapdragon 600 series, the Snapdragon 660 also has the four high performance Kryo260 cores like SD 662 and SD665 but gets a slight boost in clock speed which is 2.2GHz. The remaining four cores have the same Kryo260 Silver Cortex-A53 cores clocked at 1.8GHz just like other snapdragon SoCs in the list.

Okay now come on to the Helio G70, The CPU has two high performance Cortex-A75 cores clocked at 2.0GHz and six Cortex-A53 efficiency cores clocked at 1.7GHz. The use of Cortex-A75 cores is the more powerful and power efficient than the Cortex-A73. So, we can say that MediaTek Helio G70 is slightly better in terms of CPU performance.

GPU & Gaming Performance

Here, in GPU department Medaitek Helio G70 has the best GPU configuration while the outdated Snapdragon 660 come last in this list. The MediaTek Helio G70 has the dual -core Mali-G52 2EEMC2 GPU with 825MHz clock speed. This GPU has also been used in the Kirin 810 by Huawei technology. On the other hand, Snapdragon 660 uses Adreno 512 GPU which is quite old and does fit in 2020 technology.

The other two SoCs in the list: Snapdragon 662 and Snapdragon 665 using the same Adreno 610 GPU configuration in the chipset. So, here Helio G70 has the best GPU over the SD 662, SD 665 and SD 660.

Connectivity

Both the Snapdragon 660 and Snapdragon 665 uses the same Qualcomm X12 LTE modem which offers up to 600Mbps of download spped and 150Mbps of upload speed. The newly launched the Snapdragon 662 has the Qualcomm X11 modem which is lower than X12 modem. So, here is also the difference in its connectivity as well. This X11 modem offers up to 390Mbps of Download speed and 150Mbps of upload speed which is less than the SD 660 and SD 665.

But, the advantage with Snapdragon 662 is that it is the only processor in the list which has Wi-Fi 6 support and comes new GPS technology support “NavIC“. This new GPS technology is invented by Indian Space Research Organization. So, here for the Indian market, you can choose Snapdragon 662 over other SoCs.

In compare to other SoCs, MediaTek Helio G70 comes last in the row with less connectivity features than other three SoCs. Its modem has a maximum download speed of 300Mbps and a maximum upload speed of 150Mbps.

Camera Feature

Here we will talk about the Image Signal Processor (ISP) of these CPUs to give you a short info to measure camera features. If you don’t know what the ISP is in any mobile platform, we will make it easy to understand.

ISP (Image Signal Processor): –

“Taking the light from your camera sensor and transforming that into a beautiful looking picture is a complicated process involving a worryingly large amount of math and processing. Fortunately, digital cameras and smartphones handle this in an energy efficient way through the use of a dedicated ISP. Qualcomm Technologies integrates this hardware right into its platforms, such as the cutting-edge Qualcomm Spectra(™) 380 ISP inside the Snapdragon 855. This is a dedicated processing unit specific for photography and video that sits right alongside the CPU and other processing components.

So about that math. An ISP is built to handle a number of essential photography and video recording tasks. For starters, the ISP inside your phone runs the autofocusing algorithm that keeps your pictures sharp and in focus.”

Link 

The Snapdragon 660 has Spectra 160 ISP, Snapdragon 665 has Spectra 165 ISP and Snapdragon 662 uses Spectra 350L ISP feature. Here both SD 662 and SD 665 can support up to 25MP single camera. But in terms of expanded single camera feature in both, the SD 662 can goes maximum 192MP single camera while SD 665 only support up to 48MP. Both the SD 662 and SD 665 SoCs supports up to Dual 16MP + 16MP camera.

Here we do not know ISP information of Helio, as per the official information from MediaTek, the SoC can support up to 48MP single-camera or up to 16MP in dual-cameras in both panels of the phone. The Snapdragon 660 is last in this list with a 24MP single-camera and 16MP dual-cameras support in both panels of the device. All three CPU from Snapdragon: SD 660, SD 662 and SD 665 have ability to record 4K videos at 30fps. However in Helio G70, it has restricted at 2K video recording at 30fps.

Display, RAM, & Storage

Display features of Snapdragon 662, Snapdragon 665 and MediaTek Helio G70 are same as these three can support up to 2520x1080p Full HD+ resolution. Only Snapdragon 660 offers 2560x1600p Quad HD+ display support.  However, this is unnecessary features of Snapdragon 660 because no company will launch a smartphone with SD660 and Quad HD+ display both in budget segment of smartphone. Because, ultimately it will raise the price of the devices.

The maximum RAM support in Snapdragon 662, Snapdragon 665, Snapdragon 660 and MediaTek G70 is the same as all have the ability to support up to 8GB of LPDDR4x RAM with 1866MHz clock speed. Similar case with storage features of the SoCs. All chipset in the list supports eMMC5.1 type storage. But additionally, the Snapdragon 662 and 665 offers UFS2.1 type storage support while the Helio G70 comes with UFS2.0 type storage support. The Snapdragon 660 has the eMMC5.1 storage type support only, does not offer any other type of storage feature in the SoC.

Artificial Intelligence (AI) & Machine Learning

Being the older one in the list, Snapdragon comes with basic Hexagon 660 DSP which lacks few new features than today’s SoCs offers. The AI features such as Vector eXtensions (HVX), and Neural Processing SDK are not available in Snapdragon 660. However, Snapdragon 662 and Snapdragon 665 come with Hexagon 683 and 686 DSP which have Vector eXtensions (HVX), and Neural Processing SDK feature. However, Snapdragon 665 and Snapdragon 662 DSPs performance are very much identical but it slightly better in SD 665. So, here Snapdragon 665 DSP performance is better than Snapdragon 662 and Snapdragon 660.

Now come to the MediaTek Helio G70. Without having any particular name for DSP, the company claims to have Fast AI-Performance. As per the company claim, its Fast AI performance can able to handle all AI-camera tasks including as object recognition (Google Lens), Smart Photo Album, scene detection and segmentation with background removal, and Bokeh-shot enhancements. Apart from MediaTek NeuroPilot and Android Neural Networks API (Android NNAPI) supports, it also provide support for many other third-party AI frameworks. So, if we concludes whole figure in short, the Helio G70 has similar AI performance and abilities like Snapdragon 662 and Snapdragon 665.

Geekbench Scores

The GeekBench score of Snapdragon 662 and MediaTek Helio G70 is not available right now. So, when it available, we will let you know about it. Therefore, as of now we will take a look on the GeekBench scores of Snapdragon 660 and Snapdragon 665.

Snapdragon 660 score a 1,616 points in Single-Core while in Multi-core it passed 5,731 points. Snapdragon 665 scored 1,537 points in Single-core performance while 5,707 points in Multi-core performance. So as you can see a very minor difference between both. However, the old SoCs Snapdragon 660 is still ahead in Geekbench benchmarks score.

AnTuTu Scores

Like the GeekBench, AnTuTu score of Snapdragon 662 and MediaTek Helio G70 is also not available right now. So we will add those scores later whenever it available. Now coming to the remaining two: SD 660 and SD 665.

Here, Snapdragon 660 last in the list with least score of 1,33,324 points. With 1,39,495 AnTuTu points, Snapdragon 665 comes second. MediaTek Helio G70 with 1,94,170 AnTuTu points comes top in the list.

Conclusion – Which one is faster?

Snapdragon 662 and MediaTek Helio G70 are the newly released SoCs and it should consider more than Snapdragon 665 and Snapdragon 660. Both the newly launched chipset provide some new feature and comes with some improvements as well. The SD 660 is old CPU  so we should ignore it. In the mid-range section, MediaTek Helio G70 provides great value fro money performance which will definitely help to improve company reputation in budget segment of smartphone. While Snapdragon 662 provide new connectivity feature “NavIC” and “WiFi-6” matches with the modern need in technology.
