Thanks to CTOnews.com netizens for the clues of 4100 eyes of birds, women, nftuoa and Piankesuohuang on the road! CTOnews.com3 news on March 17, after all kinds of rumors and revelations, Qualcomm today released a new second-generation Snapdragon 7 + mobile platform. Qualcomm calls this chip "the strongest 7-series platform in the history of Snapdragon." as for how strong it is, let's take a look at it in detail.

First of all, the second generation Snapdragon 7 + mobile platform uses the Kryo CPU,1+3+4 architecture, including a super core of the highest frequency 2.91GHz, 3 performance cores and 4 efficiency 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.

In the comparison between the second-generation Snapdragon 7 + engineering prototype and the commercial terminals of the same category competition in Geekbench 6 testing, the second-generation Snapdragon 7 + CPU leads by 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.

In terms of GPU energy efficiency, the second-generation Snapdragon 7 + Adreno GPU has a lead of 55% and 61%, respectively, including the GFX Manhattan 3.01080p off-screen test and the GFX Manhattan 3.1 1080p off-screen test.

In addition to CPU and GPU, the second-generation Snapdragon 7 + mobile platform has also been upgraded in terms of imaging capabilities. It is the first mobile platform to support 18-bit 3 ISP on the Snapdragon 7 series. Compared with the image data captured by 14-bit ISP,18-bit ISP has increased by more than 4000 times, it can provide extreme dynamic range, restore rich colors and achieve high definition, and the shooting effect has been qualitatively improved compared with 14-bit ISP.

In addition, the second-generation Snapdragon 7 + can support 200-megapixel photo shooting, clearly showing every detail of the picture, and for the first time supporting 18-bit RAW domain processing features that were only available on the previous flagship mobile platform.

The second generation Snapdragon 7 + also supports ultra-dark photo shooting on the Snapdragon 7 series for the first time. In the past, dark light shooting based on 14-bit ISP can capture 6 images in a single shot. The ultra-dark light shooting based on 18-bit three ISP can capture 30 images continuously in a single shot, fuse the best part of the 30 images, and finally show a picture with brighter and higher color restoration.

In addition, there is also triple exposure 4K computing HDR video shooting, which for the first time supports dual cameras to capture single frame line-by-line HDR video at the same time, which can achieve a smooth switch between the two cameras and combine the brightest, darkest and best parts in the triple exposure to create excellent color restoration, brightness and dynamic range.

In terms of AI, the second generation Snapdragon 7 + integrates Qualcomm sensor hub, based on a new low-power AI architecture, including a dedicated AI processor, DSP and proprietary memory.

At the same time, Qualcomm also supports the AI super-resolution feature, or AI super-score, in the Snapdragon 7 series for the first time. It is based on the trained AI hyper-score neural network model, combined with the corresponding game, can further improve the game resolution, such as from the original 720p to 1080p or even higher, so as to improve the picture quality of the whole game.

On the gaming side, the second generation Snapdragon 7 + also introduces many game features that were originally supported only in Snapdragon 8 series, such as Adaptive variable Resolution rendering (Auto VRS) and Adreno image motion engine. In addition, stereoscopic rendering is also the first game feature supported in the Snapdragon 7 series platform. This feature combines the features of Unreal engine 5, and by working with the game studio, you can further render the smoke and particle effects in the game to create extreme fidelity.

In terms of communication, the second generation Snapdragon 7 + integrates Snapdragon X625G modem and RF system, supports 3GPP Release 16, and the peak downlink rate is as high as 4.4Gbps. It also supports 5G millimeter wave and Sub-6GHz, and can support carrier aggregation between the two.

In addition, this mobile platform also supports 5G+5G and 5G+4G dual cards and dual access (DSDA). When the user has two cards and one card is making a voice call, the data service of the second card will be interrupted if the 5G+5G / 4G dual card is not supported; and if the 5G+5G / 4G dual card is supported, the concurrent voice service and data service can be realized, and the two do not affect each other.

In terms of Wi-Fi, the second generation Snapdragon 7 + supports FastConnect 6900 mobile connection system, Wi-Fi 6 and Wi-Fi 6e, the highest downlink rate can reach 3.6Gbps, and supports low latency at VR level.

Finally, in terms of security, the second generation Snapdragon 7 + supports trust management engine (TME) and Qualcomm trusted execution environment (TEE). In addition, it also has a Hypervisor execution environment (HEE) support, which can run different applications on a separate OS, and it is a separate area running inside the chip. The advantage of this is that, for example, fingerprint recognition or face detection in applications can be separated from the OS area of the system, thus ensuring the security of these applications.

Generally speaking, the second generation Snapdragon 7 + inherits many features that consumers are most concerned about in Snapdragon 8 series flagship platform, and has greatly improved the experience.
