What kind of processor is SDM710? Which is better, SDM710 or SDM845?

SDM710 processor

On May 24, Qualcomm officially released the first chip of the Snapdragon 700 series: Snapdragon 710. This new product is positioned as a high-end sub-flagship. The CPU adopts a 2 large core + 6 small core design. The GPU is Adreno 616 and supports X15 baseband. 4&TImes; MIMO, the highest downlink rate is 800Mbps, and the Snapdragon 710 has 2 times the AI ​​performance improvement.

First, let’s take a look at the specific parameters of the Snapdragon 710. The Snapdragon 710 uses the same second-generation 10nm LPP manufacturing process as the Snapdragon 845. The CPU part uses the Kryo 360CPU architecture, with 2 performance cores + 6 efficiency cores (2 large cores + 6 Small core design), the highest frequency of the big core is 2.2GHz, and the highest frequency of the small core is 1.7GHz; Snapdragon 710 GPU adopts Adreno 616, which officially claims a performance increase of 35%, supports QHD+ (2K+) resolution screen, and supports up to 21:9 ratio screen. Support QC 4+ fast charge technology.

Taking pictures

Snapdragon 710 uses Spectra 250 ISP, supports slow motion video shooting, image and video noise reduction, and active depth sensing. 4K video shooting power consumption is reduced by 40%. Snapdragon 710 supports up to 32 million pixel single camera or 20 million pixel dual camera, supports 3D structured light solutions, and is compatible with the emission of other photosensitive elements.

AI performance

Qualcomm claims that the Snapdragon 710 brings 2 times the AI ​​performance improvement compared to the Snapdragon 660. It achieves stronger AI performance through Hexagon DSP/CPU/GPU + Snapdragon Neural Processing (SDK). The Snapdragon 710 supports Google ARCore and is compatible with domestic SenseTime cooperated to develop SenseAR performance optimization technology.

Baseband

Snapdragon 710 uses X15 LTE baseband, 4&TImes; 4MIMO antenna design, and uses LTE and WiFi shared antenna technology. The 4G network supports a maximum downlink rate of 800Mbps, which is 30% faster than Snapdragon 660. Snapdragon 710 supports Bluetooth 5.

According to data officially released by Qualcomm, the overall performance of the Snapdragon 710 is increased by 20%, web browsing speed is increased by 25%, application startup speed is increased by 15%, 4K video power consumption is reduced by 40%, game power consumption is reduced by 40%, and video streaming performance is reduced. Reduce consumption by 20%.

After talking about the specific parameters, let’s talk about the highlights of the Snapdragon 710. The first is the CPU. Refer to the Kryo 385 architecture of the Snapdragon 845. It can be seen that the Kryo 360 architecture of the Snapdragon 710 is still a slightly improved version based on the ARM A75+A55, A75 and A55. The A55 architecture introduces the new DynamIQ big.LITTLE architecture. Compared with the previous big.LITTLE, DyanmIQ redefines the multi-core microarchitecture. The number of Cortex-A CPUs in a cluster of the DynamIQ cluster can range from single-core to 8-core, and It also supports the mix and match between heterogeneous CPUs. The popular point is that DynamIQ supports any combination of cores such as 1 large core + 7 small cores, 2 large cores + 6 small cores.

SDM710 and SDM comparison

The youth version of the Snapdragon 845 uses the same 10nm LPP process as the 845, and uses the ARM DynamIQ connection architecture like the 845. The large and small cores are in a cluster, and the task migration does not need to cross the cluster. The efficiency is smaller than the previous BIG. The connection architecture is higher.

Snapdragon 845 has 4 large cores (A75 modified) + 4 small cores (A55 modified), and Snapdragon 710 has 2 large cores (A75 modified) + 6 small cores (A55 modified). As for the difference in the core and size ratio, are the cores exactly the same? The core of the Snapdragon 710 may be castrated slightly more in terms of cache, etc., but there are still differences. Qualcomm named the core of Snapdragon 845 as kyro380, and named the core of Snapdragon 710 as kyro360. But they are all third-generation kyro cores, all based on the revision of A75/A55.

The GPU is also the 6th generation adreno like the 845, of course the performance is much worse.

In terms of overall performance and power consumption, compared with the previous generation of 14nm Snapdragon 660, the performance is increased by about 25%, and the power consumption is reduced by 20-40% (the more onerous tasks, the greater the reduction in power consumption).

The running score is basically the same as the Snapdragon 821 full blood version, but the power consumption can be reduced by nearly half. The Xiaomi Mi 5 series mobile phones using Snapdragon 820/821 were complained by a large number of users in the summer that they were hot and stuck, not because of the weak chip, but because of high power consumption and severe heat generation. The temperature control scheduling mechanism of the mobile phone was locked and reduced. Some users have deleted the temperature control, it is cool to play games, but the phone is hot.

If you want to be more intuitive, you can simply think of the Snapdragon 710 as a full-blooded version of the Snapdragon 821 that does not lock the core and lower the frequency, and it will not be hot.

In terms of cost, the number of transistors in GPU, CPU, cache, etc. is much less than that of the Snapdragon 845, which is naturally much cheaper.

Green Light Film

Eye protection:The principle of chlorophyll defocusing is adopted to prevent the eyeball from focusing for a long time, effectively alleviate eye fatigue, and achieve better eyesight protection.

Anti-blue light, ultraviolet light:The Green Light Film can actively filter the target wavelength while providing a band in the range of 380-400nm. It can effectively block 100% harmful light.

Edge coverage:The soft material fully covers the edges of any device, so it can be affixed to curved screen and round edges, 100% provides excellent edge coverage, and there is no gap between the edges of the device.

Oleophobic and waterproof:The oleophobic coating surface of the Green Light Screen Protector can provide your phone with oleophobic and waterproof properties, which can prevent sweat, grease residue, and fingerprints.

Sensitive touch:The 0.14mm ultra-thin film does not interfere with the touch response, almost as if it does not exist. When using a mobile phone, the fingertips can be easily swiped, bringing you a comfortable gaming experience.
