### Q: When was the Kryo architecture introduced?
A: While the specific introduction date isn't in the provided text, Qualcomm announced details like the 2.2 GHz clock speed in September 2015. The manufacturer is Qualcomm, a company founded in 1985.

## Why It Matters
Kryo matters because it represents Qualcomm's strategic shift towards custom-designed CPU cores and microarchitectures rather than relying solely on off-the-shelf ARM designs. By implementing the ARMv8-A 64-bit instruction set through its own AArch64-based microarchitecture, Qualcomm can optimize performance and power efficiency specifically for mobile and embedded devices. This customization allows for heterogeneous computing solutions, integrating the CPU more tightly with other system components like GPUs and DSPs within Snapdragon platforms. For consumers and the industry, Kryo CPUs deliver the computational power necessary for advanced mobile gaming, artificial intelligence processing, and multitasking on smartphones and tablets, driving the capabilities of modern mobile technology forward.

## Notable For
- **Custom Microarchitecture**: Being a custom CPU and microarchitecture design by Qualcomm, distinguishing it from standard ARM Cortex cores.
- **64-bit Implementation**: Implementing the ARMv8-A 64-bit instruction set (A64).
- **Advanced Fabrication**: Utilization of a 14 nm lithography process for manufacturing.
- **High Clock Speeds**: Capability of reaching clock frequencies of 2.2 GHz.
- **Integration**: Serving as a core component in Qualcomm's semiconductor intellectual property portfolio.
