Qualcomm introduces Snapdragon 7+ Gen 3: Elevating GenAI in High-End Smartphones

In a recent announcement, Qualcomm has launched its latest addition to the Snapdragon lineup for mobile phones: the Snapdragon 7+ Gen 3. This new SoC (System on a Chip) follows in the footsteps of its predecessor, the Snapdragon 7+ Gen 2, and is designed for premium smartphones that offer high-end features at a more affordable price point.

The Snapdragon 7+ Gen 3 stands out as the most affordable Qualcomm SoC to feature an ARM Cortex-X core. While it may not reach the clock speeds of the Snapdragon 8 series, it still offers impressive CPU performance. The chip includes a mix of Cortex-A720 performance cores and Cortex-A520 efficiency cores, providing a balance between power and energy efficiency.

One notable improvement in the Snapdragon 7+ Gen 3 is its memory subsystem. Unlike its predecessor, which featured a 32-bit LPDDR5 memory bus, the Gen 3 version boasts a 64-bit LPDDR5X memory bus. This upgrade results in a significant increase in memory bandwidth, providing smoother performance and faster data transfer rates.

In terms of GPU performance, Qualcomm promises a 45% improvement compared to the previous generation. While specific details about the Adreno GPU configuration are scarce, it’s clear that Qualcomm has invested in additional GPU transistors to achieve this level of performance.

However, it’s important to note that the Snapdragon 7+ Gen 3 lacks certain features found in higher-end Qualcomm SoCs. For example, it does not support hardware Ray Tracing, which may disappoint those looking for graphics capabilities. Nevertheless, the chip still offers a powerful GPU that surpasses mid-tier smartphone standards.

The DSP/NPU (Digital Signal Processor/Neural Processing Unit) capabilities of the Snapdragon 7+ Gen 3 are similar to those of the Snapdragon 8s Gen 3. It supports generative AI models, marking the first time this functionality has been included in a Snapdragon 7+ SoC. However, the NPU IP remains largely unchanged, indicating that software enablement plays a more significant role in this aspect.

The camera system of the Snapdragon 7+ Gen 3 retains Qualcomm’s triple 18-bit Spectra ISPs, now equipped with the newer-generation “cognitive” IP. While the resolution limits and video capture capabilities remain the same as the previous generation, there have been improvements in image processing, including support for semantic segmentation.

On the connectivity front, the Snapdragon 7+ Gen 3 features the Snapdragon X63 integrated modem, supporting both sub-6 and mmWave spectrums. It offers 2×2 MIMO on mmWave and 4×4 MIMO on sub-6, with maximum upload speeds of 3.5Gbps and download speeds of 4.2Gbps.

Qualcomm’s FastConnect 7800 system handles wireless communication, providing Wi-Fi 7 support with 2×2 MIMO and Bluetooth 5.4. This marks the first time Wi-Fi 7 support has been integrated into a Snapdragon 7 SoC.

Overall, Qualcomm positions the Snapdragon 7+ Gen 3 as a worthy successor to its predecessor, offering improved CPU and GPU performance with a slight boost in energy efficiency. The chip introduces new hardware and software features while maintaining enough differentiation from the higher-end Snapdragon 8/8s series.

Phones powered by the Snapdragon 7+ Gen 3 are expected to hit the market in the coming months. SHARP, realme, and OnePlus are among the first OEMs to adopt this new SoC. However, it remains to be seen how popular this chip will be outside of China, where its predecessor gained significant traction.
