  • Supports both sub-6 GHz and mmWave 5G.

  • Download speeds up to 6 Gbps.

  • Dual SIM 5G support.

  • Multi-mode 5G support, including 4G LTE and 5G NR.

• Applications: Primarily used in laptops and connected devices (not widely used in smartphones anymore).

While the XMM 8160 is no longer actively used in new devices, it remains a comparable option for 5G modems in certain use cases, particularly in laptop and PC applications.

4. Huawei Balong 5000

• Huawei's Balong 5000 is a 5G modem that provides connectivity across both sub-6 GHz and mmWave 5G bands.

• Key Features:

  • Supports 5G sub-6 GHz and mmWave.

  • Download speeds up to 6.5 Gbps.

  • Multi-mode support for 2G, 3G, 4G, and 5G networks.

  • Carrier aggregation for enhanced 5G speeds.

• Applications: Found in Huawei smartphones, modems, and routers.

Although Huawei faces restrictions in some markets (such as the U.S.), the Balong 5000 still competes as a high-performance 5G modem with capabilities similar to those of the Qualcomm SDX65.

5. Unisoc Tiger T7510

• The Unisoc Tiger T7510 is a 5G modem that supports sub-6 GHz and mmWave 5G bands, targeting mid-range smartphones and IoT devices.

• Key Features:

  • Download speeds up to 4.25 Gbps (sub-6 GHz).

  • Supports dual 5G SIM cards for dual 5G standby.

  • Carrier aggregation and other advanced 5G technologies.

• Applications: Primarily in mid-range smartphones and IoT products.

While it does not offer as high a maximum download speed as the SDX65, it provides good 5G performance for mid-range devices.

6. Qualcomm X60 Modem (SDX55)

• The Qualcomm X60 5G modem (also known as the SDX55) is another 5G modem from Qualcomm, though it is a previous-generation model compared to the SDX65.

• Key Features:

  • 5G support for sub-6 GHz and mmWave.

  • Download speeds up to 7.5 Gbps.

  • Advanced carrier aggregation and dual 5G SIM.

• Applications: Found in smartphones, tablets, and laptops.

While the SDX60 is a bit older than the SDX65, it is still a powerful 5G modem with similar capabilities for smartphones and mobile devices.

Key Considerations When Choosing an Alternative:

• 5G Performance: Look at download/upload speeds, support for sub-6 GHz and mmWave frequencies, and overall 5G network coverage.

• Power Efficiency: The SDX65 is designed for mobile devices, so alternatives should offer good power efficiency for battery-powered applications.

• Carrier Aggregation: The SDX65 supports advanced carrier aggregation, which is important for maximizing 5G speed and network stability.

• Compatibility: Ensure the modem supports the global 5G bands and multi-mode operation (support for 2G, 3G, 4G, and 5G).

• Integration: Some alternatives like the MediaTek Dimensity chips or Samsung Exynos have integrated modems, while others are separate solutions (e.g., Qualcomm X60 or Huawei Balong).

Conclusion:

The Qualcomm SDX65 is a powerful and versatile 5G modem, and the alternatives listed above provide similar 5G capabilities, including support for sub-6 GHz and mmWave, carrier aggregation, and high-speed data transfer. Depending on your application (whether it's for smartphones, laptops, routers, or IoT devices), you can choose from chips like the MediaTek Dimensity 1200 AI, Samsung Exynos 5123, or Huawei Balong 5000 for equivalent performance. However, if you are focused on high-speed data and multi-band support, Qualcomm's X60 or X65 will likely remain the most optimal choice in terms of future-proofing and overall performance.
