The Snapdragon 665 is considered a necessary update to the popular Snapdragon 660, especially in GPU and AI. However, there is one more processor of the 600 series that has been underestimated and until now there are only a few smartphones that equip it. We are talking about the Qualcomm Snapdragon 670, a really powerful mid-range mobile processor, which the industry did not like to use. We do not know why this happened.
Also, we have the Helio P70, reaffirming that MediaTek continues to focus on the catalog of midline processors. This is ahead of other exponents of the company, such as the Helio P60, and offers some interesting and essentials features, as the presence of artificial intelligence in the processor core. But what does it offer compared to the Qualcomm processors and why the Snapdragon 670 has gone unnoticed compared to the more recent Snapdragon 665? Today we will try to discover it through a Snapdragon 665 vs Snapdragon 670 vs Helio P70 comparison.
All three are octa-core processors with 64-bit memory architecture but work in different micro-architectures. The Snapdragon 665 works with Kryo 260 and the Snapdragon 670 has the Kryo 360 architecture. Finally, MediaTek does not handle Kryo micro-architectures but the Helio P70 is also based on ARM. Also, the Helio P70 is designed in the 12nm FinFet process. However, the Qualcomm processors have been built with a smaller manufacturing process technology, 11nm for the Snapdragon 665 and 10nm for the Snapdragon 670. Remember that as long as the number of Fin Fet Process is lower, better is the energy efficiency of a SOC.
The 8 cores of Helio P70 are divided into two parts according to the management of the tasks. So, there are 4 main Cortex ARM-73 cores at a maximum clock speed of 2.1GHz and 4 cores for power saving Cortex ARM-53 at 2.0GHz. As mentioned, the Snapdragon 665 has the CPU architecture Kryo 260 and basically uses 2 powerful cores based on Cortex-A73, with clock speeds up to 2.0GHz and 6 efficiency cores based on Cortex-A53 with speed clock up to 1.8GHz. Finally, the Snapdragon 670 has a customized Kryo 360 architecture where 2 Cortex-A75-based cores at a speed of 2.0GHz are combined with 6 Cortex-A55 energy-efficient cores with a processing speed of 1.7GHz.
The microarchitectures A75 and A55 are better than the A73 and A53, so Snapdragon 670 is the winner that can easily overcome the Snapdragon 665 and the Helio P70. Although the Helio P70 reaches a slightly higher clock speed, it is not enough to surpass it. In addition, the manufacturing process is also better.
In AnTuTu, the Helio P70 has registered a total score of 156.906. This score is very much on par with Qualcomm’s Snapdragon 670 that registers a total of 157,271 points in AnTuTu. The Snapdragon 665, on the other hand, scored lower than the Snapdragon 670 and even lower than the Snapdragon 660 in CPU performance, with only 57,939 points. However, the Snapdragon 665 has a higher GPU score, but it is still behind the Snapdragon 670. Finally, its overall score is only 125,092 points.
The MediaTek Helio P70 has the ARM Mali-G72 GPU MP3 that offers a maximum frequency of 900MHz. The Snapdragon 665 has the Adreno 610 GPU, however, the Snapdragon 670 has the Adreno 615 GPU, which is a later generation with more power.
Again, the Snapdragon 670 manages to lead in one category. The Adreno 615 is a GPU with better performance than the Adreno 610 GPU and the ARM Mali-G72 MP3 GPU. However, you will only notice the differences if you use them all three in parallel in real life. Otherwise, there will be an almost equal performance.
Now is the time to compare the optics department of chipsets. We start with the Helio P70 that has support for a single camera up to 32MP (30 fps) or a dual camera configuration of up to 24MP + 16MP (90fps). Also, it is possible to record 4k videos at 30 fps. It also offers sensor AI features such as face detection and scene detection, EIS, anti-bloom engine, multi-frame noise reduction, real-time HDR recording and viewing with Zig-Zag HDR included, and much more.
In Qualcomm, the camera department is mainly managed by the ISP. In the Snapdragon 665 we find the Spectra 165 ISP, thanks to this, the processor is able to handle the configuration of 16MP in double camera sensors or can support up to 25MP of a single camera. For more resolution, this processor gives you the ease of up to 48MP. But for this, must compromise the MFNR and the ZSL, which are available with the 16-megapixel or 25-megapixel camera arrangement. As for recording videos, this processor can record videos from 720p to 240 fps or videos from 1080p to 120fps. While in normal mode it can go up to 4k at 30 fps.
Finally, the Snapdragon 670 has a better ISP, the Spectra 250. With the help of this ISP, the SoC can reach 192MP in camera images. And compared to the previous one, the 48MP does have support for the MFNR. The other features are the same as the Spectra 165 of the Snapdragon 665. However, the image processing will be much better with this ISP.
The Snapdragon 665 is compatible with a Full HD+ screen with a resolution of up to 2520 x 1080. While Snapdragon 670 is compatible with HDR10 Full HD+ screen up to 2560 x 1600. While the Helio P70 also supports a Full HD+ screen with a resolution of up to 2160 x 1080 and a maximum aspect ratio of up to 20:9.
The Helio P70 has great artificial intelligence technology inside to execute machine learning and deep learning codes. This results in a dedicated AI accelerator that can reach a speed of up to 280GMAC per second.
In the case of Qualcomm, in this segment the DSP is the most important, it helps to process RAW AI data. In the Snapdragon 665, is the Qualcomm Hexagon 686 DSP, which is the successor of the Hexagon 685 DSP Snapdragon 670. It has been shown that the Hexagon 685 has a good performance but as the 686 is its most direct update, offers better processing of artificial intelligence. Besides that, the rest of the little things related to the processing of AI are the same, for example, both have Qualcomm Hexagon Vector eXtension (HVX) and Qualcomm All-Ways Aware Technology, etc.
Helio P70 supports connectivity options in the LTE category Cat-7 DL and Cat-13 UL that offers 300MBit/s of download performance. It also has general connectivity options such as Dual 4G VoLTE, Bluetooth 4.2 (Low Energy), Beidou, Galileo, Glonass, GPS and Wi-Fi 5 (a/b/g/n/ac).
This category is exactly the same in Qualcomm SoCs. Both use the Qualcomm X15 LTE modem that provides up to 600 Mbps of Cat-12 download speed and 150 Mbps of Cat-12 upload speed. The rest of the connectivity options are also the same. Both have dual-band Wi-Fi, Dual 4G VoLTE, Bluetooth 5.0 and other basic connectivity options.
Winner: Snapdragon 670 > Snapdragon 665 > Helio P70
The truth is that the Snapdragon 670 is a high-performance mobile processor, better than the 665, the Helio P70 and the old but popular 660. We do not know what the reasons for it are, but we think that the factor economic is the key. In the only aspect where the 665 is unquestionably superior is in the AI processing. Also, the MediaTek Helio P70 offers similar features in all categories, but it is clear that it is one step lower than the Qualcomm chipsets. However, all three are excellent options for midrange devices.
