Ist der Snapdragon Prozessor eine Cortex A8 Architektur oder hat er ähnlichkeiten zu einem CortexA8?

Although Scorpion and Cortex-A8 have many similarities, based on the information 

released by Qualcomm, the two cores differ in a number of interesting ways. For example, 

while the Scorpion and Cortex-A8 NEON implementations execute the same SIMD-style 

instructions, Scorpion’s implementation can process128 bits of data in parallel, compared to 64 

bits on Cortex-A8. Half of Scorpion’s SIMD data path can be shut down to conserve power. 

Scorpion’s pipeline is deeper: It has a 13-stage load/store pipeline and two integer pipelines—

one of which is 10 stages and can perform simple arithmetic operations (such as adds and 

subtracts) while the other is 12 stages and can perform both simple and more complex 

arithmetic, like MACs. Scorpion also has a 23-stage floating-point/SIMD pipeline, and unlike on

Cortex-A8, VFPv3 operations are pipelined. Scorpion uses a number of other microarchitectural

tweaks that are intended to either boost speed or reduce power consumption. (Scorpion’s 

architects previously designed low-power, high-performance processors for IBM.)  The core 

supports multiple clock and voltage domains to enable additional power savings.

Overall, Qualcomm has made a huge investment in creating a custom implementation of the

ARMv7 architecture.
