THEM Qualcomm In November, it announced its new processor aimed at premium smartphones. Snapdragon 8 Generation 2🇧🇷 The chip is the implementation of Ray Tracing technology, Wi-Fi 7, more artificial intelligence in cameras, etc. brings important changes and additions such as

But is the new processor very different from its predecessor? That’s why TecMundo compared Snapdragon 8 Gen 1 with Gen 2 and pointed out the key differences and similarities between the chips. Payment!

Technicial Specifications

One of the biggest expectations regarding the launch of the new processor was linked to the chip manufacturing process. In the first model, Qualcomm worked with Samsung to produce parts at 4nm. Now 4 nanometers continueshowever manufacturing is on behalf of TSMCjust like the Snapdragon 8+ Gen 1.

As for the number of cores, the version has the system 1+4(2+2)+3, that is, a combination of colors Cortex-X3 (3.2 Ghz), Cortex-A715 and Cortex -A510 is used. The previous generation also had Cortex-A510 efficiency cores, but the main core and performance cores were responsible for Cortex-X2 and Cortex-A710.


An interesting thing that is often not noticed is the amount of cache that has increased from 6MB to 8MB with the new driver. Gained 8th Gen 2 memory support LPDDR5X type RAMGen 1 only supports the slightly slower LPDDR5 standard; and also Will support UFS 4.0 storagefar superior to the already integrated UFS 3.1.

Ray Tracing video card

In addition to the processor changes, Qualcomm also brought some improvements to the graphics card. The main advance of the GPU, called Adreno 740existence of structures. ray tracing acceleration🇧🇷 The technology isn’t necessarily new to the smartphone world, as MediaTek has already implemented this with the Dimensity 9200, but it’s a first for the Qualcomm chip.

The manufacturer promises meaningful figures regarding the Snapdragon 8 Gen 1. When we talk about performance, the difference should reach 25%energy consumption will decrease by 45%. In the scenario where the Vulkan API is used in games, Qualcomm promises up to 30% gains.

Graphical improvements with Ray Tracing in games

The company that has not made any changes on screen compatibility, i.e. both Snapdragon 8 Gen 1 and Gen 2 Supports Quad HD+ displays with a refresh rate 4K at 144Hz or 60Hz.

Artificial intelligence

In the new venture, Qualcomm added two AI coprocessors to the new chip, 4.35x performance compared to the previous model. Underlining that its energy efficiency is superior, the company reveals a 60% difference in consumption per watt.

Some new frameworks have also been added, such as the Tensor Core accelerator and the Hexagon co-CPU itself. With this, the chip becomes the brand’s first chip to be supported by the series. INT4 instructionswhich significantly improves the AI ​​performance of devices.


Processor and AI are factors directly related to the cameras of new smartphones. Now, Qualcomm is launching Cognitive ISPie an Image Signal Processor that can “better recognize” all layers of a photo.

Unlike the Snapdragon 8 Gen 1, the next generation uses a semantic segmentation system from neural networks to enable the camera to contextualize information about faces, hair, clothing, skin and more. Then, when the photo is taken, post-processing optimizes each of these elements individually to create the image with higher graphics fidelity.

Cognitive ISP Post Processing

The new chip is also supported by new camera sensors, but in general Supports up to 200 MPAs with the 8 Gen 1 and 8 Plus Gen 1. Meanwhile, the new Snapdragon processor will be compatible with the ISOCELL HP3, the first 200 MP sensor made by Samsung. In addition, the chip has these features: Record in 8K60An interesting update considering that its predecessor was limited to 30 frames at the same resolution.


Connectivity is one of Qualcomm’s strengths, and the model released last year already does a good job with the X65 modem. However, with the new announcement, the X70 appeared, which can reach 10Gbps in download and 3.5Gbps in upload.

The company’s new FastConnect 7800 system already supports the technology with Wi-Fi 7 Bluetooth 5.3🇧🇷 There is also the possibility of using two 5G chips simultaneously if the smartphone has this option.

When we talk about sound, there are differences in the presence of the new model mainly. spatial sound🇧🇷 The second generation features a head positioning tracking feature, so even if a user is listening to music and their head is turned to the side, the technology “converts” this sound so that it is reproduced differently. necessary path.

Compatible Smartphones

Since its launch in December 2021, Snapdragon 8 Gen 1 is now available for Xiaomi 12, Motorola Edge 30 Pro, Galaxy S22, Realme GT2 Pro etc. It can be used on many high-end devices such as Below, check out which smartphones should debut with the new Snapdragon 8 Gen 2.

  • Samsung Galaxy S23 Series
  • Vivo X90 Pro Plus
  • Xiaomi 13 and 13 Pro
  • Oppo Find X6 Pro
  • OnePlus 11
  • Motorola X40 (Edge 40 Pro)
  • iQOO Line 11
  • Red Magic 8 Pro
  • ZTE Axon 50 Ultra
