I think you should look up what a chipset is. From Wikipedia:
A chipset is a set of electronic components in an integrated circuit that manage the data flow between the processor, memory and peripherals. It is usually found in the motherboard of a computer. Chipsets are usually designed to work with a specific family of microprocessors. Because it controls communications between the processor and external devices, the chipset plays a crucial role in determining system performance.
Just so we're clear, the chipset doesn't include a CPU or, usually, GPU. There really isn't an equivalent with the ARM architecture, and to say otherwise is just wrong. What we're talking about with the X8 Moto is using a brand new dual-core design. As in, this is the very first family of devices to launch with it. Here, I'll let WIkipedia show you. You tell me where on this table the same qualcomm SoC (again, not a chipset) is used in 2012.
Snapdragon (system on chip) - Wikipedia, the free encyclopedia
Your argument of "it's just a redesigned 2012 design" is misleading, and a bit disingenuous, since if you look at CPU design at all you'll realize that it's all derivative of previous architectures and generations. To think that a company can just take a dual-core design and slap a new GPU on it is really making light of the amount of engineering that goes into designing an SoC.
Wait, I'm getting ahead of myself. I keep using SoC and I haven't actually said what that is, and I'm going to assume that you don't know either, since you keep using chipset. Again, from Wikipedia:
A system on a chip or system on chip (SoC or SOC) is an integrated circuit (IC) that integrates all components of a computer or other electronic system into a single chip. It may contain digital, analog, mixed-signal, and often radio-frequencyfunctions?all on a single chip substrate. A typical application is in the area of embedded systems.
A typical SoC consists of:
These blocks are connected by either a proprietary or industry-standard bus such as the AMBA bus from ARM Holdings. DMA controllers route data directly between external interfaces and memory, bypassing the processor core and thereby increasing the data throughput of the SoC.
Now do you understand what the difference between a chipset and SoC are? Good, back to the point I was making. SoC's aren't modular. You can't pick and choose what works together. Qualcomm took two Krait 300 cores (same cores as in the S600 which is found in the One and S4) and mated them with the Adreno 320 GPU. So, this is a brand new dual core design as far as SoC's go for Qualcomm. That point can't be argued. Last year's dual core Snapdragon had Krait 200 cores and the Adreno 225 GPU. The GPU is much slower in last year's SoC, and the CPU cores are also less efficient and also slower.
We honestly don't know all that much about the custom processors that Moto is using for the contextual stuff. We can assume that they're some sort of DSP, and if you know anything about DSP's they are even more specific to the task they're designed to perform than ARM chips, which makes them even more efficient at doing what they do.
Go ahead and install Open Mic+ and see what happens to your battery life. Keeping the CPU alive just to listen for voice commands is extremely inefficient. That's what these special processors do. Offload these relatively mundane tasks so that the CPU can focus on more demanding things.
