Which is the best processor between Xiaolong 670 and Xiaolong 710? Performance comparison between Xiaolong 670 and Xiaolong 710
4hw.com.cn: Recently, vivo officially released a new machine, vivo x23. Vivo x23 is the first mobile phone equipped with Xiaolong 670 in China. Many people are curious about which is better, Xiaolong 670 or Xiaolong 710 Processor? Let's have a look.
Surprisingly, previously, the world had agreed that the popular "Shenu" snapdragon 670 had strengthened its AI performance, so Qualcomm decided to open up a new snapdragon 7 Series platform. In fact, snapdragon 670 has been renamed as snapdragon 710 as the first product of 7 series. This time, the return of Xiaolong 670 really surprised everyone.
The brand new Xiaolong 670 seems to come directly from Xiaolong 710. The specifications of the two products are very close. At first glance, it is easy to ignore their differences.
The biggest inconvenience of Xiaolong 670 and Xiaolong 710 is that their X12 baseband does not support 4x4 MIMO, and does not support 10bit video decoding and output. Therefore, the maximum downlink rate of Xiaolong 670 is reduced from 800Mbps of Xiaolong 710 to 600mbps, and HDR support is lost.
In addition, Xiaolong 670 and Xiaolong 710 maintain a high degree of similarity.
The Xiaolong 670 adopts the same CPU core configuration as the Xiaolong 710, i.e. the same kryo 360 architecture, 2 + 6 big.LITTLE In the design of large and small cores, the difference is that the frequency of two large cores is slightly reduced from 2.2GHz of Xiaolong 710 to 2GHz, while the frequency of six small cores remains unchanged at 1.7GHz.
And the result of this design is the same as Lei Feng's analysis of Xiaolong 710. Qualcomm does not blindly pursue the overall multithreading performance of the processor, but focuses on improving the single core efficiency and performance of the large core, and plays a better role in the face of the poor use of multi-core programs.
The GPU part of Xiaolong 670 is Adreno 615. Although Lei Feng has no more knowledge about the specific parameters of Qualcomm's Adreno, the naming of Adreno 615 is lower than that of the same Adreno 6xx Series in Xiaolong 710, so the performance should be slightly lower. Qualcomm said the GPU performance of the snapdragon 670 is 25% higher than that of the snapdragon 660. (as a comparison, the increase of Xiaolong 710 compared with Xiaolong 660 is 35%)
According to the analysis of foreign media AnandTech, Xiaolong 670 uses the same hexagon 685 DSP and spectrum 250 ISP as Xiaolong 710, only reducing the operating frequency of the two. Therefore, the camera specifications supported by Xiaolong 670 are also reduced from 32 million for single shot / 20 million for double shot to 25 million for single shot / 16 million for double shot.
Xiaolong 670 is not far away from Xiaolong 710 in positioning. When Lei Feng first saw a brief introduction to the new model, the first reaction was' this is a low-frequency Xiaolong 710 '? Although Qualcomm said that snapdragon 670 is indeed a "different design", we are still curious about how much cost can snapdragon 670 reduce on the basis of snapdragon 710?
On the surface, it must be the customer's demand that makes the snapdragon 670. In a sense, this chip shows Qualcomm's advantages in customer demand driven and fast adapting to the market.
The snapdragon 670 is currently on the market and is expected to launch commercial devices in the coming months.
