Qualcomm reveals its new processor Snapdragon S4 on its white paper. Here’s a block diagram of the chip from the Qualcomm White Paper:It claims that this aSMP (asynchronous Symmetric Multi-Processor) approach delivers a 25 to 40% improvement in operating power for a given performance, as you can see in the following graph:
|2011/2012 SoC Comparison|

|Samsung Exynos 4212||32nm||2 x ARM Cortex A9 w/ MPE @ 1.5GHz||ARM Mali-400 MP4||2 x 32-bit LPDDR2||2012|
|TI OMAP 4430||45nm||2 x ARM Cortex A9 w/ MPE @ 1.2GHz||PowerVR SGX 540||2 x 32-bit LPDDR2||Now|
|TI OMAP 4460||45nm||2 x ARM Cortex A9 w/ MPE @ 1.5GHz||PowerVR SGX 540||2 x 32-bit LPDDR2||Q4 11 - 1H 12|
|TI OMAP 4470||45nm||2 x ARM Cortex A9 w/ MPE @ 1.8GHz||PowerVR SGX 544||2 x 32-bit LPDDR2||1H 2012|
|TI OMAP 5||28nm||2 x ARM Cortex A15 @ 2GHz||PowerVR SGX 544MPx||2 x 32-bit LPDDR2||2H 2012|
|Qualcomm MSM8x60||45nm||2 x Scorpion @ 1.5GHz||Adreno 220||2 x 32-bit LPDDR2*||Now|
|Qualcomm MSM8960||28nm||2 x Krait @ 1.5GHz||Adreno 225||2 x 32-bit LPDDR2||1H 2012|
They pointed out "Other than TI's OMAP 5 in the second half of 2012 and Qualcomm's Krait, no one else has announced plans to release a new microarchitecture in the near term. Furthermore, if we only look at the first half of next year, Qualcomm is the only company that's focused on significantly improving per-core performance through a new architecture. Everyone else is either scaling up in core count (NVIDIA) or clock speeds. As we've seen in the PC industry however, generational performance gaps are hard to overcome - even with more cores or frequency."
The performance is expected a big improvement over previous architectures.
