Shulou(Shulou.com)11/24 Report--

On March 17, Qualcomm launched the iterative work of the first generation Snapdragon 7 mobile platform-the second generation Snapdragon 7 + mobile platform. The reason for surpassing the "second-generation Snapdragon 7" and directly calling it "7 +", according to Qualcomm, is that the chip is so powerful in all aspects that it can be directly named after "7 +".

Now, the second generation Snapdragon 7 + mobile platform has been released, and we all know its relevant parameters. Is it really, as Qualcomm says, so powerful that it needs to skip one level to define it? Today, we might as well analyze this brand new mobile platform in detail to see how unique it is.

Performance and energy efficiency for a mobile platform chip, we believe that the most concerned is the CPU performance.

The second generation of Snapdragon 7 + uses Kyro CPU, and the core architecture is 1-3-4 three-cluster architecture, including a super core of the highest main frequency 2.91GHz, 3 performance kernels and 4 efficient cores. The overall performance of CPU is 50% higher than that of the previous generation platform.

In terms of GPU, the overall performance of the Adreno GPU adopted by the second generation Snapdragon 7 + is two times higher than that of the previous generation 7 series platform, which is also the biggest improvement in GPU performance among Snapdragon 7 series products at present.

At the same time, in terms of energy efficiency, the energy efficiency of the second generation Snapdragon 7 + is 13% higher than that of the previous generation platform. On the one hand, it benefits from the upgrade of the process (TSMC 4nm), on the other hand, it is also related to the chip design.

There are a lot of comparative data to show the advantages of the second generation Snapdragon 7 + mobile platforms CPU and GPU in terms of performance and energy efficiency.

In the comparison between the second-generation Snapdragon 7 + engineering prototype and the commercial terminals of competing products in the Geekbench 6 test, the CPU of the second-generation Snapdragon 7 + leads 35% in single thread and 24% in multi-thread. In terms of GPU performance, the second-generation Snapdragon 7 + has a 25% lead over competitive products in the GFX Aztec Ruins 1440p benchmark.

Of course, for a mobile platform chip, running performance and energy efficiency performance are not all, if high performance can only maintain output for a period of time, certainly not, whether it can maintain high performance output state for a long time, that is, how the "physique" of a chip is sometimes more important.

At this point, there is also relevant data to see the continuous performance output ability of the second generation Snapdragon 7 +. For example, using the GFX Manhattan 3.01080P with the second-generation Snapdragon 7 + running 20 rounds at the same time, we can see that the absolute performance of the competition is 18% lower than that of the second-generation Snapdragon 7 + at the beginning of the run.

To the fifth round, the performance output of the second generation Snapdragon 7 + is still very stable, but the competition has declined significantly, and the gap between the two sides has widened to 27%. The GPU performance of the products has declined sharply since the 7th round, and the absolute performance gap has reached 65%. At this time, the performance of the second generation Snapdragon 7 + remains very stable.

In terms of energy efficiency, using the two products to run GFX Manhattan 3.01080p off-screen and GFX Manhattan 3.11080p off-screen, the second generation Snapdragon 7 + mobile platform also showed significant advantages over competitive products, reaching 55% and 61% respectively. This kind of performance can be said to be quite excellent.

Then there is a comparison of the actual game tests.

Using the second generation Snapdragon 7 + engineering prototype and the commercial production machine of competitive products, the actual test was carried out on the "original god" Sumicheng route for 30 minutes to maintain the ambient temperature of 25 degrees Celsius and the picture quality of 720p. It can be seen that the average frame rate of the second generation Snapdragon 7 + is 10% higher than that of the competition, and its energy efficiency is 17% higher than that of the competition.

In addition to "the original God", "Arena of Valor" is also a game that everyone often plays. During Arena of Valor's 30-minute test, the ambient temperature was 25 degrees, and the configuration of 120 frames with high-definition picture quality showed that the average frame rate of the second generation Snapdragon 7 + reached 119.25fps, and more importantly, its energy efficiency was 29% higher than that of competitive products, indicating that such a stable high frame rate game performance can last longer on the second generation Snapdragon 7 +.

The above series of analysis and comparative tests show that the second generation Snapdragon 7 + mobile platform is indeed very powerful in basic CPU and GPU performance, and can even reach the level of flagship or sub-flagship mobile platform, which can be said to be a "leap" for Snapdragon 7 series chips.

AI and image performance are only the powerful foundation of a mobile platform chip. in addition to computing performance, the second generation Snapdragon 7 + is also the existence of configuration fullness in other aspects. Like AI.

In terms of AI performance, there are also comparative data of the second generation Snapdragon 7 + and competitive products. The tests are respectively based on various neural network models of MLPerf. As can be seen from the chart below, the comprehensive AI performance of the second generation Snapdragon 7 + is 3 times higher than that of competitive products.

Specific to individual test projects, the second generation Snapdragon 7 + also has advantages, such as image classification is 2.5 times higher than competitive products, object detection is 2 times, image segmentation v2.0 is more than 3 times ahead, and language comprehension is nearly 3.7 times.

In addition, the second generation Snapdragon 7 + also supports AI super resolution, which can intelligently enhance the lower resolution game pictures and photos to higher picture quality (from 1080p to 4K), achieving excellent visual effects.

In addition to AI, nowadays smartphones are also very concerned about image capabilities, and whether taking pictures is good or not is becoming an important reference standard for people to buy mobile phones.

In terms of images, the second generation Snapdragon 7 + supports the architecture of 18-bit 3 ISP for the first time on Snapdragon 7 series. Compared with the previous generation 7 series 14-bit ISP, the image data that can be captured increases by 4096 times, so that your phone can grab enough information like a professional imaging device.

For example, in the comparison of the photos taken by 14-bit 's ISP and 18-bit ISP in the same scene below, we can find that 18-bit has a very obvious advantage in the overall dynamic range and HDR capabilities.

In terms of photo pixels, the second generation Snapdragon 7 + can support up to 200 megapixels, while in night scene photography, the second generation Snapdragon 7 + also supports the feature of ultra-dark photo shooting on the 7 series for the first time. Help you also take very clear and amazing photos at night.

This is because the 18-bit 3 ISP of the second generation Snapdragon 7 + platform can capture 30 frames of images at a time, which means that the image data processing ability in night scene mode has been improved by 5 times, and then the best and clearest parts of the 30 frames have been fused to make a qualitative leap in the brightness, clarity and color of the synthesized images.

In addition, the second generation Snapdragon 7 + mobile platform also supports triple exposure 4K computing HDR video shooting on the Snapdragon 7 series for the first time, and for the first time supports dual cameras to simultaneously capture single-frame progressive HDR video, which can achieve smooth switching between the two cameras.

The brightest, darkest and best parts in the middle of the triple exposure are combined to create excellent color reduction, brightness and dynamic range. Finally, make the overall details, dynamic range and color of the video very rich and clear.

Another "first time" is that the second-generation Snapdragon 7 + mobile platform supports 18-bit RAW domain video shooting on the 7-series platform for the first time. Due to the support of 18-bit RAW, the mobile phone has really entered the field of more professional image and video processing, and users can edit a variety of unimaginable images by obtaining a larger amount of original data, thus greatly enhancing the playability and fun of shooting.

In short, in terms of key AI and imaging, the second generation Snapdragon 7 + mobile platform also surpasses its peers, introducing many innovative features of flagship mobile platforms for the first time, which is undoubtedly an exciting thing for mid-range mobile phone consumers.
