Its about the same, its Gpu is the 305 vs our 230 though.
See the diagram for moto X with 2x Krait (its 1.7ghz compared to ours' 1.5 with better gpu).

The review is very helpful.
I really more concern about web browsing and multi-tasking abilities about the phone.
I use the browser a lot, and the AHD is doing ok. I would wait to see more web browsing reviews.
As for multi- tasking, maybe they are the same here. 1GB ram maybe the main reason to limit their muti-function.
I do some reading on AHD, and need to refer to dictionary every now and them, and in the meaning time using browsers, checking email.
sometimes my AHD just freezes ( on Holoblur rom). I am not sure if moto G would also just freeze due to same 1gb ram.
