Both phones come in two basic versions: one with 2GB of RAM and 16GB of internal storage and a slightly more expensive configuration that bumps RAM to 3GB and storage to 32GB.

Both phones support microSD cards for adding storage space.

Other hardware similarities exist too, including a 5.5-inch 1080p IPS display, a 5MP front-facing camera, and a rear camera with phase detect autofocus (PDAF) and dual-tone LED flash.

Both phones also support 802.11ac Wi-Fi.

The Redmi Note 3 does have an FM radio and an infrared transmitter for TV remote duties, features the M3 note lacks.

The M3 note uses a capacitive touch-based fingerprint sensor based on Meizu’s mTouch 2.1 technology that is also found in the more expensive PRO 5 and PRO 6. The Redmi Note 3 also comes with a capacitive touch-based sensor on the back of the phone. Both phones unlock quickly, but I found the M3 note’s sensor to be far more reliable, especially at handling moisture and changes in temperature. At one point I could not even get the Redmi Note 3 to register a fingerprint during the enrollment process.

One feature that helps set both of these phones apart from their peers is a large battery. While not swappable, the greater than 4000mAh battery in each phone should provide ample battery life.

The biggest difference between these two notes is the SoC each packs inside

The MediaTek Helio P10 in the M3 note uses an octa-core CPU with a performance and power-saving cluster of four Cortex-A53 cores each for a total of eight cores.

The Snapdragon 650 in the Redmi Note 3 pairs its power-saving cluster of four A53 cores with two Cortex-A72 cores, which should give it a performance advantage in most applications.

There’s also two different GPUs—an ARM Mali-T860MP2 for the M3 note and a Qualcomm Adreno 510 for the Redmi Note 3—which have their own relative strengths.

Both SoCs include an integrated baseband processor.

MediaTek’s Category 6 LTE modem offers up to 300 Mb/s down and 50 Mb/s up with 2x20 MHz carrier aggregation and 64-QAM on the downlink.

Qualcomm’s X8 LTE modem in the Redmi Note 3’s Snapdragon 650 SoC offers the same downlink capability but boosts uplink speed to 100 Mb/s max by adding 2x20 MHz carrier aggregation (still 16-QAM).

Both phones support Dual SIM Dual Standby (DSDS) operation, which means both SIMs are active for receiving calls or messages, but only one SIM can make a connection at a time because they share a single radio.

Each phone’s card tray has two slots: The M3 note can have two NanoSIM cards or one NanoSIM and one microSD card, while the Redmi Note 3 can use one MicroSIM and one NanoSIM or one MicroSIM and one microSD card.

Frequency band support is tailored for the Asian and European markets, although neither phone supports B20 for the latter. There’s no support for North American LTE frequencies, limiting the phones to HSPA+ operation.
