The Xperia ZR uses a Snapdragon S4 Pro APQ8064 which is a generation older than the Snapdragon 600 and uses a different naming convention.

The Xperia Z1 Compact uses a Snapdragon 800 which is the Snapdragon 600's bigger brother.

Hi,

ARM Cortex is a series of reference microarchitectures released by ARM Holdings PLC that span the ARMv6, ARMv7, and ARMv8 families.

The ARM Cortex A series are meant for applications and are often found in mobile phones

The ARM Cortex R series are meant for real time applications and are found in signal processors

The ARM Cortex M series are meant for microcontroller applications and are found in control systems often alongside R series devices.

ARM Holdings does not manufacture any devices themselves. Manufacturers such as Apple, AMD, NVidia, Qualcomm, and Samsung licence the designs in a synthesizeable format that can be integrated with their own designs.
Some manufactures may go a step further and customize the designs to their choosing or even design their own microarchitecture that is compatible with a particular instruction set. For example, the Qualcomm Krait is a series of ARMv7 compatible microarchitectures that is similar (if not directly derived from) the ARM Cortex A15.

I myself use a Samsung Galaxy S4. The North American edition has a Qualcomm Snapdragon 600 microprocessor which employs four Krait cores. The international edition has a custom Samsung Exynos 5 microprocessor which employs four Cortex-A15 and four Cortex-A7 in a power balanced configuration.
