The Exynos Modem 5300 5G is made using a 4nm EUV process by Samsung Foundry, a significant improvement over the Exynos Modem 5123’s 7nm EUV fabrication process. It makes the Exynos Modem 5300 a lot more power-efficient than previous-generation modems. The new telecommunication chip offers peak download speeds of up to 10Gbps while providing ultra-low latency with support for FR1, FR2, and EN-DC (E-UTRAN New Radio – Dual Connectivity) technology. The peak upload speeds are claimed to be up to 3.87Gbps. Of course, it supports mmWave and sub-6GHz 5G networks in both SA (Standalone) and NSA (Non-Standalone) modes.
It is compatible with 3GPP’s 5G NR Release 16 standard, which aims to make 5G networks much faster and more efficient. In the LTE mode, the Exynos Modem 5300 supports peak download speeds of up to 3Gbps and peak upload speeds of up to 422Mbps. It can be connected to a smartphone chipset via a PCIe connection.
On paper, the Exynos Modem 5300 that’s designed by Samsung’s System LSI arm appears similar to Qualcomm’s Snapdragon X70 Modem, which is also capable of offering up to 10Gbps download speeds and up to 3.5Gbps upload speeds on compatible 5G networks.
