About Snapdragon

Snapdragon is a family of mobile system on chips by Qualcomm. Qualcomm considers Snapdragon a “platform” for use in smartphones, tablets, and smartbook devices.

The original Snapdragon CPU, dubbed Scorpion, is Qualcomm’s own design. It has many features similar to those of the ARM Cortex-A8 core and it is based on the ARM v7 instruction set, but theoretically has much higher performance for multimedia-related SIMD operations. The successor to Scorpion, found in S4 Snapdragon SoCs is named Krait and has many similarities with the ARM Cortex-A15 CPU and is also based on the ARMv7 instruction set.

All Snapdragon processors contain the circuitry to decode high-definition video (HD) resolution at 720p or 1080p depending on the Snapdragon chipset. Adreno, the company’s proprietary GPU technology, integrated into Snapdragon chipsets (and certain other Qualcomm chipsets) is Qualcomm’s own design, using assets the company acquired from AMD.

Snapdragon chipsets, as of 2011, include a CPU “Krait” (with speeds up to 2.5 GHz), GPU “Adreno 225″, 2G/3G/4G modem, and severalHexagon DSP coprocessors.
