Unisoc T7225 (T612) vs Qualcomm Snapdragon 665 vs Qualcomm Snapdragon 6s 4G Gen 1

Unisoc T7225 (T612)

The Unisoc T7225 (formerly Unisoc T612) is an entry level octa core SoC with two fast ARM Cortex A75 cores at up to 1.8 GHz and six power efficient ARM Cortex A55 cores at up to 1.8 GHz. The SoC furthermore includes a LTE modem (TDD-LTE, FDD-LTE, TDSCDMA, WCDMA, CDMA, GSM), a LPDDR3-933 / LPDDR4/4X-1600 memory controller, an ARM Mali G52MP1 GPU at 614 MHz and a tri core ISP (24, 8 and 8 MPixels max). Compared to the Unisoc T610, the T7225 offers one GPU core less (G52 MC1 versus MC2).

The chip is manufactured by TSMC on 12nm FinFET process.

Qualcomm Snapdragon 665

The Qualcomm Snapdragon 665 (SM6125) is a fast mid-range ARM-based SoC largely found on Android tablets and smartphones. It features 8 Kryo 260 cores (custom design, 64-Bit capable) that are divided in two clusters. A fast cluster of four cores with up to 2 GHz (Kryo 260 Gold - Cortex-A73 derivate) and a power saving efficiency cluster with up to 1.8 GHz (Kryo 260 Silver - Cortex A53 derivate). Both clusters can also be used together.

In addition to the 8 CPU cores, the SoC integrates a mid range Adreno 610 GPU with a LPDDR4 memory controller (dual-channel)  and supports Wi-Fi (802.11ac + MIMO, max. 867 Mbps), Bluetooth 5, and LTE (X12 LTE modem with up to 600 Mbps download and 150 Mbps upload).

Power Consumption

Thanks to the new 11 nm LPP process, the energy efficiency should be quite good.

Qualcomm Snapdragon 6s 4G Gen 1

The Qualcomm Snapdragon 6s 4G Gen 1 (SM6115-AC) is a renamed Snapdragon 662 SoC of the lower mid-range for (Android based) smartphones and tablets. The processor unit contains 8 Kryo-260 CPU cores (4x ARM Cortex-A73 with up to 2.1 GHz and 4x ARM Cortex-A53 with up to 1.8 GHz). The Qualcomm Adreno 610 is used as the graphics unit

The SoC comes with the third generation of Qualcomm's AI Engine and also includes Bluetooth 5.1. It is interesting to note that Qualcomm describes the Wi-Fi capability as "WiFi-6-ready", meaning you can connect to a WiFi 6 network, but not all parts of the standard are supported. The new WPS3 security protocol can be used. Support for the HEIF image file format and the Indian satellite network NavIC are also new.

The performance should be very similar to the old Snapdragon 662 (see for benchmarks).

The Snapdragon X11 is integrated as an LTE modem, which supports LTE Cat.13 in the uplink and downlink, as well as 2x2 MIMO in the downlink. The maximum transmission speed is 390 MBit/s (download) and 150 MBit/s (upload).

In terms of mass storage, a maximum of UFS 2.1 is supported, the memory limits are 32 GB and LP4x.

The SoC is manufactured using the 11 nm process.
