Snapdragon 730 vs 845: Specs & Benchmarks

The Snapdragon 730 and Snapdragon 845 are both Qualcomm processors, but they target different market segments: the 730 is a mid-range chip from 2019, while the 845 was the 2018 flagship. In raw CPU and GPU benchmarks, the older 845 generally outperforms the 730, but the 730 offers better power efficiency and newer features like a more advanced AI engine and support for Wi-Fi 6. This article breaks down the specifications, benchmark comparisons, and real-world implications to help you decide which matters for your needs.

Background: Why Compare a Mid-Range to a Flagship?

When the Snapdragon 845 launched in early 2018, it powered the year’s premium Android phones—devices like the Samsung Galaxy S9, OnePlus 6, and Google Pixel 3. It was built on a 10nm process and featured Qualcomm’s Kryo 385 cores, a custom design based on ARM Cortex-A75 and A55. The Snapdragon 730 arrived in 2019 as the successor to the Snapdragon 710, aimed at upper mid-range phones such as the Xiaomi Mi Note 10 and the Samsung Galaxy A80. It also uses a 10nm process, but with newer Kryo 470 cores (based on Cortex-A76 and A55). The comparison is interesting because it pits a mature flagship against a newer mid-range chip, and the results are not as one-sided as you might expect.

Benchmark Performance: CPU and GPU

In synthetic benchmarks, the Snapdragon 845 generally scores higher than the 730, especially in multi-core CPU tests and GPU tests. For example, in Geekbench 5 (a common CPU benchmark), the 845 typically scores around 500-550 in single-core and 2200-2400 in multi-core, while the 730 scores around 540-550 in single-core and 1600-1700 in multi-core. The single-core scores are surprisingly close because the 730’s Cortex-A76 core is newer and more efficient than the 845’s Cortex-A75, but the 845’s four high-performance cores give it a significant multi-core advantage. In GPU benchmarks like GFXBench and 3DMark, the Adreno 630 in the 845 is substantially faster than the Adreno 618—often by 40-60% in sustained performance. For gaming, the 845 can handle demanding titles at higher settings with more consistent frame rates, while the 730 may require lower settings for the same smoothness.

Real-World Performance and Efficiency

In everyday tasks like browsing, social media, and video streaming, both chips feel fast, and most users won’t notice a difference. The 730’s newer CPU architecture (Cortex-A76) is more power-efficient than the 845’s older Cortex-A75, so the 730 often delivers better battery life in light usage. However, under sustained heavy loads (like gaming or video editing), the 845’s higher peak performance can be beneficial, though it may also consume more power and generate more heat. The 730 also supports newer features like Wi-Fi 6 (if the phone manufacturer includes the necessary radio), which can improve network performance in congested areas. For AI tasks, the 730’s Hexagon 688 DSP with a dedicated AI accelerator is actually more capable than the 845’s Hexagon 685, so apps that use on-device AI (like camera scene recognition or voice assistants) may run faster on the 730.

How to Choose Between Them

When deciding between a phone with a Snapdragon 845 and one with a Snapdragon 730, consider your priorities:

Gaming: If you play heavy games, the 845 is the better choice due to its superior GPU. Look for phones with good cooling to sustain performance.
Battery life: For general use, the 730’s efficiency may give you longer battery life, especially if the phone has a large battery.
Camera and AI: The 730’s newer ISP and AI engine can support better computational photography features, like night mode and scene optimization.
Connectivity: The 730 supports Wi-Fi 6 (if the phone has it), which is a future-proofing advantage.
Price: Phones with the 845 (even used) may be cheaper than newer 730 phones, but consider the age of the device and software update support.

Common Problems and Misconceptions

A common misconception is that newer always means faster. While the 730 is newer, it is not a flagship chip, so its GPU is intentionally weaker to differentiate it from the 800-series. Another issue is thermal throttling: both chips can throttle under prolonged heavy load, but the 845’s higher power draw can lead to more significant throttling if the phone’s cooling is inadequate. Also, note that benchmark scores vary between devices due to RAM, storage, and software optimization, so use them as a rough guide rather than absolute truth. If you’re buying a used 845 phone, check for battery health and software support, as older devices may not receive the latest Android updates.

Frequently Asked Questions

Is the Snapdragon 730 better than the 845 for gaming?

No, the Snapdragon 845 is significantly better for gaming due to its Adreno 630 GPU, which outperforms the Adreno 618 in the 730 by a wide margin. The 845 can handle most games at high settings, while the 730 may need lower settings for demanding titles.

Which chip has better battery life?

The Snapdragon 730 generally offers better battery life for everyday tasks because its newer CPU cores are more power-efficient. However, actual battery life depends heavily on the phone’s battery capacity and screen, so it’s not a guarantee.

Does the 730 support 4K video recording?

Yes, the Snapdragon 730 supports 4K video recording at 30 fps, and some phones may offer 4K at 60 fps with the right software. The 845 also supports 4K at 60 fps, so both are capable for video.

Which chip has better AI performance?

The Snapdragon 730 has a more advanced AI engine (Hexagon 688 with a dedicated AI accelerator) compared to the 845’s Hexagon 685. This means AI tasks like camera scene detection and voice recognition may be faster and more efficient on the 730.

Is it worth buying a phone with the 845 in 2025?

If you can get a used 845 phone at a good price and it has a decent battery and software support, it can still be a good option for gaming and performance. However, the 730 may be a better choice for battery life and newer features like Wi-Fi 6, depending on the specific phone.

Conclusion

In summary, the Snapdragon 845 is the more powerful chip overall, especially for gaming and heavy multitasking, but the Snapdragon 730 offers better efficiency and newer features. Your choice should depend on your specific needs: if you prioritize gaming and raw performance, go with the 845; if you want better battery life and modern connectivity, the 730 is a solid choice. Always consider the entire phone package, not just the chip.
