The Snapdragon 7+ Gen 2 is Qualcomm’s most powerful mid-range chipset, but is it truly as powerful as the Snapdragon 8+ Gen 1? The Snapdragon 8 series is Qualcomm’s flagship line of processors for smartphones and is currently led by the Snapdragon 8 Gen 2. The Snapdragon 7 series is designed for premium mid-range smartphones, while the Snapdragon 6 and Snapdragon 4 series are targeted at lower mid-range and budget-friendly smartphones, respectively.
Both the Snapdragon 7+ Gen 2 (SM7475-AB) and the Snapdragon 8+ Gen 1 (SM8475) are 4nm chipsets manufactured by TSMC. They also have the same 1+3+4 CPU core arrangement. For its CPU cores, the Snapdragon 7+ Gen 2 has a Cortex-X2 prime core clocked at 2.91GHz, three Cortex-A710 performance cores clocked at 2.49GHz, and four Cortex-A510 efficiency cores clocked at 1.8GHz. The Snapdragon 8+ Gen 1 has identical CPU cores but is clocked higher. Its Cortex-X2 cores are clocked at 3.2GHz, its three Cortex-A710 cores are clocked at 2.75GHz, and the four Cortex-A510 cores are clocked at 2.0GHz.
The higher clock speed of the CPU cores in the Snapdragon 8+ Gen 1’s indicates better performance than the Snapdragon 7+ Gen 2. Geekbench results when using a Qualcomm reference design device with a Snapdragon 8+ Gen 1 chip show scores of 1316 points in the single-core test and 4199 points in the multi-core test. In contrast, the Snapdragon 7+ Gen 2 scored 1031 points in the single-core test and 3707 points in the multi-core test, according to Nanoreview.
On the GPU side, the Snapdragon 8+ Gen 1 has an Adreno 730 GPU clocked at 900MHz. The Snapdragon 7+ Gen 2 also has a still unknown Adreno GPU, but it most likely isn’t as powerful as that of its flagship rival. However, Qualcomm says that it offers 2x the performance over the Snapdragon 7 Gen 1’s GPU.
The 7+ Gen 2 has a Snapdragon X62 5G Modem that offers up to 4.4 Gbps peak download speeds. It also supports four carriers (mmWave), 2×2 MIMO (mmWave), and 4×4 MIMO (Sub-6). In contrast, the Snapdragon X65 modem inside the Snapdragon 8+ Gen 1’s has a peak speed of 10 Gbps, and supports eight carriers (mmWave), 2×2 MIMO (mmWave), and 4×4 MIMO (Sub-6). Both chipsets have the same Qualcomm FastConnect 6900 Wi-Fi/Bluetooth chip with a peak speed of up to 3.6 Gbps, Wi-Fi 6E, tri-band support, Bluetooth 5.3, and support for Bluetooth Low Energy Audio.
Like MediaTek’s Dimensity 1080 mid-range chip, the Qualcomm Spectra Image Signal Processor (ISP) in both phones boasts an 18-bit ISP and supports 200MP image sensors. However, while the Snapdragon 7+ Gen 2 is capable of recording in 4K at 60fps, the Snapdragon 8+ Gen 1 can record in 8K at 30 fps, and in 4K at 120fps. The Snapdragon 8+ Gen 1 also supports displays with up to 4K UHD resolution at 60Hz and QHD+ at 144Hz. In contrast, the Snapdragon 7+ Gen 2 supports a maximum display resolution of QHD+ at 120Hz. Both chipsets support Quick Charge 5.
While the Snapdragon 7+ Gen 2 no doubt packs some flagship-grade features, it’s still not on the same level as the Snapdragon 8+ Gen 1, which has a more powerful CPU and GPU, superior modem, features 8K recording, and supports displays with a higher resolution and refresh rate. Unsurprisingly, smartphones with a Snapdragon 8+ Gen 1 chip should outperform those with a Snapdragon 7+ Gen 2 chipset.
